Yet many runners might find _____easier than running in hot weather. That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is _____than in warmer conditions. Besides, the body needs less water _______a cold day than in warm weather. This information comes from John Brewer, a _______ scientist at St. Mary’s University in London. Brewer says every movement runners make produces heat. He explains that one way in which we lose heat _____by sweating, and that the body also loses heat by transporting the blood to the surface of the skin. But sweating puts much strain（张力）on the heart, particularly in hot conditions because it is______ harder to lose heat when the external environment is warm ______. In addition, running in higher temperatures results in faster heart rates. Scientists find that heart rates are about 6 percent higher in the hotter conditions. However, running in cooler temperatures has ______advantages. One is that the body does not have to work so hard to pump blood to the skin surface in cooler temperatures, which means running requires less energy.

On March 14 in 2018, one of science’s brightest stars went dark. Stephen Hawking, the world-famous scientist, died at 76 in Cambridge, UK. Hawking is considered by many to be the greatest scientist in history since Albert Einstein. He came up with the theory that the universe began with the Big Bang and will end in black holes. His theory became the important base for a lot of later research. He also wrote books to help common people understand the universe. His most famous book is A Brief History of Time（《时间简史》）， which has sold more than 10 million copies around the world, according to CNN. Besides his scientific achievements, Hawking was also someone who had a strong will and positive attitude. When Hawking was 21, he was told that he had a serious illness that stopped him from walking and talking. Later in life, he had to sit in a wheelchair and “speak” using a computerized voice. But this didn’t stop him from living a meaningful and colorful life. “If one is physically disabled, one cannot afford to be psychologically(心理上) disabled as well.” he once said. Hawking travelled around the world to attend science meeting, visiting every continent, including Antarctica. He was also a fan of popular culture and appeared on TV shows such as Star Trek and The Big Bang Theory. He celebrated his 60th birthday by going up in a hot-air balloon. When he was 65, he took part in a zero-gravity flight to experience weightlessness. He hoped to travel into space one day. In 2013, Hawking spoke about how he felt life was unfair when he first knew his illness. “But now, 50 years later, I can be quietly satisfied with my life,” he said peacefully. 【1】What is the author’s purpose in writing the article? A.To tell us the brightest star went dark and Hawking died. B.To introduce Hawking’s famous book A Brief History of Time. C.To describe how Hawking overcame his serious physical illness. D.To introduce Hawking’s life to help people remember him. 【2】How important is Hawking’s theory that the universe began with the Big Bang and will end in black holes? A.It helped him write all his books to help ordinary people understand the universe. B.A lot of research which came after the important theory later depends on it. C.It made his famous book sell more than 10 million copies all over the world. D.This achievement led him to become a strong and positive famous man. 【3】Which of the following statement is TRUE? A.He travelled around the world just in order to pay a visit to every continent. B.Although Hawking had a serious illness, he still had a wonderful and meaningful life. C.He was a fan of up-to-date culture and hosted TV shows such as Star Trek and The Big Bang Theory. D.He was so positive and strong that he still felt satisfied when he was first told he had a serious illness. 【4】What does Hawking mean by “If one is physically disabled, one cannot afford to be psychologically(心理上) disabled as well.”? A.Although one man has a disabled body, he can still have a strong will and positive attitude. B.If someone is physically ill, he can’t pay more money to treat his psychological disability. C.If one is physically disabled, he needn’t have psychological disability because it’s too much for him. D.Although one man has disabled illness, he can also be psychologically disabled in his life. 【5】In what order did the following take place in the story? a. He said that he was happy with his life 50 years later. b. He had to sit in a wheelchair and began to use a computer to help him speak. c. He took part in a zero-gravity flight to experience weightlessness. d. He went up in a hot-air balloon. e. He couldn’t walk and talk at the age of 21. A.e-b-a-d-c B.a-e-b-d-c C.e-b-d-c-a D.a-e-d-b-e

It is a question that has confused parents for many years: why do children refuse to eat greens? Now, two American experts believe they have the answer. After studying dozens of babies as they played with various objects, the researchers noted that they were far more unwilling to touch plants than other things. They believe this is because evolution (生物进化) has biologically made children be wary of plants. Due to susceptibility (敏感性) to illness or injury in the early years of life, the body has designed an inner defence mechanism (内部保护机制) that limits a child’ s contact with plants, they think. The researchers believe this is why children turn their noses up when faced with a plate of broad beans. The findings are published in a paper by Dr. Annie E Wertz and Dr. Karen Wynn, both psychologists at Yale University. They wrote, “Throughout human evolution... plants have been important in human’s life. Yet, for all of these benefits, plants have always caused very real dangers.” “Plants produce toxins (毒素) as defences that can be harmful, or even deadly. Some plants also produce physical defences, such as thorns (荆棘) can damage tissues (组织) and cause effects over the whole body.” They added, “We predicted that babies may have behavioural strategies that reduce dangers caused by plants.” To test their theory, the researchers studied how children aged eight to 18 months old reacted when presented with a variety of objects. It took much longer for children to grab plants; objects that were pretended to look like plants also caused a slow response time. For parents attempting to spoon some peas into the mouth of their child, this finding should come as welcome relief. 【1】The underlined word “they” in Paragraph 3 refers to_____? A.the parents B.the researchers C.the babies D.the plants 【2】What does the underlined word “wary” in the third paragraph mean? A.Curious B.Afraid C.Tired D.Certain 【3】What did early humans probably do in order to keep away from illness or injury? A.They choose to make more man-made things. B.They didn’t allowed their children to touch plants. C.They chose to have little contact with plants. D.They tried very hard to escape from the past. 【4】What was plants’ role in early human’s life? A.They were important, in spite of danger. B.They reacted badly to human evolution. C.They contributed to the most deaths and illness. D.They developed human physical defenses against dangers. 【5】What’s the passage mainly about? A.Why some plants are harmful. B.How humans react to plants. C.Why children don’t like to eat greens. D.When children from behavioural strategies.

One Monday morning, Paul and his classmates were in the science laboratory for their chemistry lesson. The students were going to work in pairs to do an experiment. Before they began, the teacher gave them this description of the different stages of the experiment. Stage 1: Prepare the equipment: a test tube, a crucible（坩埚）, a Bunsen burner（煤气灯）and tongs（钳子）. Stage 2: Weigh 5 grams of baking soda (小苏打) and put it in a crucible. Stage 3: Heat 10 ml of hydrochloric acid (盐酸) in a test tube. Stage 4: Pour the warm acid onto the baking soda and continue to heat the mixture. Result: The acid reacts with the bicarbonate（碳酸氢盐）to form water, carbon dioxide gas and salt. The hotter the mixture, the quicker the reaction. Continue to heat the mixture until the water evaporates（蒸发）, leaving the salt in the crucible. Paul and his partner followed the instructions and set up their equipment. Paul went to the cupboard to get a bottle of hydrochloric acid. He found that there was only one bottle in the cupboard so he took that. There was no label on the bottle and Paul didn’t check with the teacher if it was the right solution(溶液). He measured the liquid and poured it into a test tube. Using tongs to hold the test tube, he heated it over the Bunsen burner. That’s when things started to go wrong. The liquid in the test tube was not hydrochloric acid. When it was heated, it formed a thick cloud of white gas. Soon the room was full of this strong smelling white gas. All the students started coughing and their eyes hurt. The teacher immediately opened the windows and ordered the students to leave the laboratory at once. She realized that the liquid was acrylamide (丙烯酰胺) and that it is poisonous. Fortunately, nobody was injured in the incident. However, it taught the students and the teacher a good lesson. 【1】The teacher and her students planned to make ________ in the experiment. A.water B.salt C.acrylamide D.carbon dioxide gas 【2】How can they make the reaction quicker? A.By putting more hydrochloric acid. B.By heating the hydrochloric acid. C.By making the water cooler. D.By making the mixture hotter. 【3】Why did Paul make the mistake? A.There was only one bottle. B.His partner didn’t help him check it. C.There was no label on the bottle. D.He didn’t pick the right one out of the bottles. 【4】What happened when Paul heated the liquid? A.His teacher ordered him to stop it at once. B.The white poisonous gas was formed. C.All the students left the lab at once. D.Someone was injured in the accident. 【5】What lesson did the incident teach the student and the teacher? A.Never leave a bottle without a label in the chemistry lab. B.Obey your teacher’s instructions in the chemistry lab. C.Acrylamide can’t take the place of hydrochloric acid. D.While something unusual happened, leave the lab at once.

NEVER! 【2】 For example, they insist that if we could clone a new Einstein, we would make more progress on physics; and if we could get a new Shakespeare, we would enjoy more profound classic literary works and ... But how can we guarantee that another Hitler could not be brought back to life “thanks to” cloning? Moreover, can we give birth to a baby who exactly shares your grand grandpa’s genes? We would be confused by that relationship or kinship.【3】 Some scientists believe that we can get the organs we need to save people’s life from the cloned counterpart. But is it unfair to them? Even if they are not the creatures of nature but of technology, they are a kind of life.【4】 I do not suppose this action is humane. 【5】 It is another violation of the natural law. Life should be a cycle from birth to death and then rebirth and re-death. Every round of change can breed more varieties of genes. Thereby our human species can live rather than copying ourselves repeatedly, which I believe would lead to the final retrogression(退化) of human species. A. I do not think we can be granted the right to kill them and take out the organs for our use. B. If we can always replace our old organs with new ones, we will predictably never die. C. Thus, the problem unavoidable arises: should we permit human cloning? D. And in that case, we would find ourselves lost in an embarrassing and disorderly situation. E. Some people maintain that it can save talents.
