A simple mosquito bite can mean serious illness or death. So we spray large areas with chemicals to wipe out mosquitoes. But this has a bad influence on the whole ecosystem and your health. Now there’s a new device (装置), which claims to keep you and your loved ones mosquito­free： What are we talking about? Mosquitron, a brand new type of bug (虫子) catcher, designed by two German engineers, is perfect for clearing your home of all annoying and dangerous flying pests! How does it work? ◆It is easy to set up; plug it in — and away you go! ◆It lures (引诱) the flying pests near using a safe, completely harmless UV light. ◆A reverse fan sucks the insects through a one­way trapdoor. ◆Once trapped in the drying basket, they are dried to death by the fan within 2 minutes. ◆You can simply empty the dead bugs into the trash, without even touching them. ◆No need for batteries or any chemicals. How much does it cost? It’s now ＄179.99. It may seem expensive at first, but when you consider most devices need regular, expensive refills and don’t work for more than 10 minutes, this is a pretty good deal. In fact, competitor products using the same UV technology are priced at over ＄250! Now you can buy it from the supplier’s website with 50% off and with free shipping for a limited time by clicking here. Note: The device can only be returned or exchanged if it arrives damaged, and you must pay in advance. 【1】What is the characteristic of a Mosquitron? A.It is easily recharged. B.It is battery­powered. C.It is almost silent when operating. D.It kills mosquitoes with UV light. 【2】What can you enjoy if buying a Mosquitron online now? A.A high discount. B.A cheap delivery.

The spine (脊柱) stands at the center of your health, providing your body with structure and support. It also contains a major collection of nerves that deliver electric signals from the rest of the body to your brain. So it’s important to take care of it. Staying in a good position is one of the most important things to keep your spine healthy. A proper position means standing or sitting while keeping your spins straight, except for its natural bending. Positions play a vital part even when you’re asleep. Stomach sleeping is far from a good idea. Many people prefer sleeping on their side, which is in the interests of their spine. Sleeping on your back has lots of benefits yet can cause lower back pain and put some pressure on your spine. Staying still for too long — even if your position is good — can be hard on your back. Especially if you work at a task most of the day, it’s important to get up and stretch (伸展) periodically. Strength exercises with light weights like push-ups can also help by strengthening the muscles. However, don’t overdo the exercise, as repeated movements can hurt the muscles around the spine, as trying to lift heavy weights with poor technique. Vitamins also affect the health of your spine. In particular, vitamin B and omega-3 fatty acids help keep nerves healthy. Another important part is vitamin D, which is required for strong bones. Vitamin D can come from some foods, but it’s also absorbed from sunlight, so it may help to do some exercises outside. At last, many of the actions necessary to keep a spine healthy are similar to those used to protect your health in other ways. So protect your back, and the rest of the body will benefit. 【1】Which sleeping position is best for our spine according to the passage? A. B. C. D. 【2】What is suggested in paragraph 3? A.Strengthening muscles around the spine. B.Repeating a certain movement more. C.Doing a proper amount of exercise. D.Staying still in a good position. 【3】What can we infer about vitamins? A.Vitamin B reacts with omega-3 fatty acids. B.Abundant vitamin D guarantees strong bones. C.Vitamin D can’t be absorbed without sunlight. D.Doing push-ups outside increases vitamin D intake. 【4】What is the best title for the text? A.Stay still, stay healthy B.Good position, good spine C.Healthy means, healthy spine D.Proper exercise, proper weight

There may be no job more reactive than firefighting. You wait for the alarm to sound; when it does, you go and fight fires. However, what if there is an algorithm (计算程序) that can take the guesswork out of fire prevention? For more than a year, the Fire Department of New York (FDNY) has been doing just that. Using a data tool called FireCast 2.0, it has been prioritizing (排序) which ones of the hundreds of thousands of buildings in the city are at the highest risk of having a fire. The software applies an algorithm from five city agencies, taking into account as many as 20 different risk factors. It wasn’t that long ago, in fact, that even a fire department as sophisticated (配备精良) as FDNY was keeping track of buildings in card catalogues in local fire houses. Each structure would have its own card with basic information on it — when it was built, construction materials — and from that, company commanders were expected to determine which buildings were to be inspected (检查). Building inspections were a key part of fire prevention in cities like New York, and that, as you might suspect, wasn’t a very efficient way to handle them. Usually, the FDNY struggled to meet its annual goal of inspecting 10 percent of the 330,000 buildings in the city for which it was responsible. But FireCast 2.0 has already simplified that process, allowing the department to more accurately target the most fire­prone buildings, many of which haven’t been inspected for years. The FDNY is pleased with the big advance it has made in what's known as “smart firefighting”, but it’s only a first step. Later this year, the department is expected to upgrade to FireCast 3.0, an even more powerful tool that will analyze three years’ data from 17 different city agencies for every one of the 330,000 buildings. Each will be given a fire risk score. But that list will be updated daily — if a building receives a trash violation, for instance, its score may rise on the next day’s list. Compiling (汇集) the data from all those buildings will take only 90 minutes, according to a report from the National Fire Protection Association. A very different approach to the future of firefighting was unveiled (揭露) recently by the U.S. Office of Naval Research. It’s an 18­pound robot named SAFFIR, and it was designed by engineers at Virginia Tech to put out fires where they’re most dangerous. During a recent test, SAFFIR was able to find fire through thick smoke and extinguish (扑灭) the flames. Maybe more impressively, it displayed its sea legs, able to stay upright on a rolling ship. That, according to SAFFIR’s designers, may have been their biggest challenge. SAFFIR still struggles to navigate (穿过) doorways and stairwells. In the test, in fact, its movements were controlled by a human. While it will likely be paired with a human for some time, SAFFIR may eventually be able to move and make decisions on its own. 【1】According to the passage, what’s the main function of FireCast 2.0? A.To make the alarm sound for a longer time. B.To reduce firefighters' chances of being injured. C.To prevent the fire from spreading further. D.To predict places that are more likely to catch fire. 【2】What can we learn from Paragraph 2? A.The FDNY doesn’t keep track of buildings in card catalogues. B.The FDNY is only responsible for inspecting buildings in New York. C.The FDNY has failed to meet its annual goal of building inspections. D.The FDNY gets its staff’s workload reduced by using FireCast 2.0. 【3】According to the passage, FireCast 3.0 ________. A.can analyze more data than FireCast 2.0 does B.has already been used by each fire department C.will update the fire risk scores every 90 minutes D.will keep a record of information on buildings in 13 cities 【4】According to the passage, SAFFIR ________. A.is able to make decisions on its own B.is not ready to be brought into use C.was originally designed to be used on ships D.is mainly used to lead the way for firefighters

I grew up eating eggs from white shells; I didn't know they could be any other color. Our eggs came from the grocery store in styrofoam packaging, and the eggs in the refrigerators at all my friends' houses were exactly the same. Life in the 1970s and 1980s meant no farmer's markets, no trips to farms and no concept of food variety. When I began buying my eggs at the farmer's market, things changed. The eggs were brown and usually in paperboard cartons or Styrofoam cartons that were clearly being reused. I know I'm not the only one who had that experience with eggs, so it's no wonder that many people assume brown eggs are more nutritious. If we're working off the assumption that all white eggs at the grocery store come from big factory farms and that all brown eggs come from local farmers who raise free­range chickens... sure. Brown is better. But is that true? Eggshell color is determined by the breed of the hen, not by the conditions in which the chicken is raised. Generally speaking, you can tell whether eggs will be white by looking at a hen's earlobes, the colored skin on the side of the head. Hens with white earlobes generally lay white eggs. Hens with brown or reddish earlobes generally lay eggs that are brown, or sometimes light green, blue or a speckled creamy color, according to Michigan State University Extension. No one breed of hen, however, is proven to lay a more nutritious egg than another, despite the color of the eggshell. Not all eggs are created equal because not all hens are raised the same way. A test done by Mother Earth News on eggs taken from 14 flocks around the country whose hens were allowed frequent access to fresh pasture, land covered with grass, found that true free­range eggs were nutritionally superior to eggs sold in grocery stores. “True” free­range means just that eggs from the grocery store that are marketed as free range do not necessarily come from hens that have spent their days wandering the barnyard, getting fresh air and eating a natural diet. When “Free­range” is on an egg carton, it means that the chickens can move around their building and have access to the outdoors “during their production cycle”． But access doesn't guarantee time outside. There's no regulation that says getting to that door has to be easy, how big the outdoor area must be, or that a chicken ever has to get outside. A chicken in a crowded henhouse may never get to the door, and if it manages to go through it, it may find there's no room for it in the small area outside. That's why it's so hard to determine if free­range eggs at the store come from truly free­range chickens. At a farm or farmers' market, you can ask about the conditions that the hens' are raised in before you buy. Another factor in the nutrition of an egg is the hens' diet. Although chickens are not vegetarians by nature—bugs and worms are part of their natural diets—Consumer Reports tested grocery store eggs and found that “hens fed vegetarian diets tended to have more of certain vitamins and omega­3s than those from hens fed a conventional diet”. So when you're choosing eggs and aiming for nutrition, don't judge an egg by its shell color. White eggs can be just as nutritious as brown eggs. Hens that are kept in conditions that are natural to them—with access to the outdoors, sunlight and exercise—and fed a good diet are what you're looking for. To find them, you'll need to ask some questions and, perhaps, pay a little more, because raising hens in pastures costs more than raising them at factory farming. 【1】When the author first saw eggs at a farmers' market, ________. A.they were fresher than those in grocery stores B.they had an unusual colour C.they cost less than those he had bought before D.they were variously packed 【2】It is implied in the passage that nowadays ________. A.true free­range chickens can no longer be found anywhere B.so­called free­range hens remain in henhouses all day long C.the word “free­range” is only used as a means of cheating D.the definition of “free­range” can sometimes be ambiguous 【3】We can learn from the passage that ________. A.nutritional value of eggs depends on nothing but what hens eat B.a diet mixed with plants and worms makes eggs more nutritious C.farmers should feed hens scientifically to get high­quality eggs D.the breed of hens should be improved for the purpose of nutrition 【4】To get eggs richer in nutrition, you need to ________. A.analyse their nutritional composition B.investigate how the hens are raised C.assure yourself of the eggs cost price D.discover where the eggs come from

Travel and illness go hand in hand. How many times have you been on the road or traveling by plane and within a three-day time the flu comes knocking? 【1】Ways to prevent? Like all good things having a set list or ingredients to fight against getting sick while travelling is necessary. Take Your Herbs (药草) With You. By all means, you can pack your vitamins but, also pack those herbs. 【2】 herbs have been studied to show an improved immunity (免疫力) of a person who suffers from respiratory (呼吸道的) infections too. A great herb to have on a hand (especially if you intend trying a new restaurant) will help settle that upset digestive track. (消化道). Do Not Ignore Symptoms 【3】 This bitter spice (苦涩的香草） can save several days spent in misery. However, sometimes we have to travel for business, so postponing (拖延）is looked down upon. If this is the case, check your insurance coverage when it comes domestic and international traveling. This is cautious move when it comes to needing medical assistance while traveling. 【4】 Walking around the city, running, or exercise of some sort will help fight off travel illnesses. We would all like to walk around for an entire week, but be sure to clock in some exercises or low cardio action action (有氧运动）. Cardio helps our immunities to stay in shape and traveling can be a bit dangerous on that front. There is a lot of waiting around, so take that little extra time to jog in place or run. Pack Vitamins This is an easy one to forget. As a last minute check, pack some vitamins you nearly take at home. Just because traveling doesn’t mean you get a back seat to when it comes to the flu.【5】 A.Is there anything to be done? B.Movement keeps you healthy. C.Swimming is a good kind of exercise. D.Don’t tkae too many things while traveling. E.But the vitamins you take will be helpful to your cold. F.Andrographis paniculata (穿心莲) has been known to treat bacterial infections. G.Before traveling, if symptoms start to show, postpone traveling if possible.

When Mike Mushaw joined the national bone marrow (骨髓) registry three years ago, he never really gave it a second thought. About six months after the sign-up, Mushaw did get a call that his bone marrow _______ a patient in Virginia. Mushaw didn’t know it at the time his donation would go to a five-month-old girl named Eleanor. Neither did he know whether his donation would _______. Eleanor, sick with a rare immuno deficiency disease, had seldom left her house _______ to travel to the hospital or the doctor. Her immune system was far too weak to risk even the most _______ human contact. Her mother, Jessica, told NBC, “The _______ were to either get a transplant or face death.” Still, there was no _______ of success. Instead, after a few weeks, the doctors came back with _______ news: Eleanor’s condition hadn’t just improved — Mushaw’s bone marrow had _______ her. Mushaw says: it was more of a _______ and happy feeling than anything. About six months after the procedure, Eleanor’s parents sent him an e-mail to thank him for saving her life. “When I was told it was a little girl, I ________,” Mushaw says. But their surprising ________ was only beginning. Mushaw and Eleanor FaceTime ________ to check on her progress. In August, about a year after Eleanor’s ________ transplant, Mushaw invited her family to one of his games. Tiny shouts of “Mike!

阅读下面材料，在空白处填写1个适当的单词或括号内单词的正确形式。 Did you know that what you think you like and don’t like is often the result of false 【1】 (believe)? As humans, we tend to be 【2】 (ease) influenced when it comes to liking or disliking something, and we’re happy to have our existing opinions 【3】 (confirm). But once they became fixed, we often lose our ability to be 【4】(object) and we don’t like to have our ideas challenged. Generally speaking, human beings are not good at taking a balanced view of things. For instance, we unconsciously start to listen for and select information that 【5】 (match) our understanding and turn a blind eye to information that doesn’t, 【6】 (reject) it out of hand. We don’t always like to accept new information that doesn’t match up with what we already believe. As a result, we often don’t even consider the reasons behind 【7】 opposing point of view. Instead, we look for evidence that confirms 【8】 we have already thought, and which conforms to our own point of view. We’re more likely【9】 (give) meaning to information that matches those we’ve already believed. In other words, we are biased (偏见) towards certain information.【10】can come as a shock when information we trusted is actually exposed to be untrue.

读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。 “Misssy,” I cried to my wife. “Did you put his banana skin on my desk?” “No, honey, Meghan probably did.” As I’d feared, she had missed the real purpose of my question, which was to make it clear to her that she hadn’t done her job of defending my desk against the invader-our naughty girl. I abandoned the conversation. I sat at my desk and stared at the screen. I waited patiently for ideas to come to me as I tried to think up exam questions for a test I would give my English students. My wife was off to a party somewhere, but I was not alone. Meghan, our 22-month-old angel, kept me company. Yet her plans seemed to go against mine. She followed a daily routine that was both time-consuming and challenging. It included certain basic tasks: watching the fish, sweeping the floor in her room, climbing up and down on her bed. At first I was able to concentrate on designing my test paper. But I was soon sidetracked. I had not counted on the arrival of the “bib-bibs”---“bib-bibs” were birds. “Bib-bibs!” Meghan screamed excitedly, her eyes alive with expectation. She insisted that I came with her to the window. “In a minute. Just let me finish this question.” I said. She pulled me by the hand (two fingers, actually) toward the window. I saw myself as a fool, being led to watch the “bib-bids”. They chattered and leaped back and forth on the lawn just outside our apartment window. Meghan was absorbed, but as I watched them, I still thought about my work. With her attention off me, I left the window and went back to my desk. Five minutes later, she returned. She reached up to my keyboard and pressed a bunch of keys, adding a long line of scrabbled letters to my question. I struggled to bring my annoyance under control. “No, thank you, Meghan. Daddy’s seen your work. I will do it myself.” She backed off. 注意： 1. 续写词数应为150左右 2.请按照如下格式在答题卡上的相应位置作答。 A few minutes later, she stood in front of me with her shoes and socks in her hand. ______________________________________________________________________________________________________________________________________________________________ I finally decided to take Meghan to the park. ______________________________________________________________________________________________________________________________________________________________
