A study has warned that seafood supplies from the world's oceans could be almost gone by the middle of the century. The researchers say there has already been a breakdown in wild populations of almost one third of currently fished sea-foods. The study says that means their catch has fallen by ninety percent from their highest level. Boris Worm of Dalhousie University in Nova Scotia Canada led the intentional team that did the study. Professor Worm says species have recently been disappearing from oceans at an increasing speed. At this rate he says all seafood species could collapse by 2048.
Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty, in, fifty years.Some scientists said parts of the world do have problems but others arc doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research.
The study appeared earlier this month in Science magazine.
The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appears to increase the risk of fish kills and beach closures from harmful algae growth.
The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide. They studied records from the United Nations Food and Agriculture Organization from 1950 to 2003. And they examined archaeological information and other historical records for twelve coastal areas. That research reached back over a thousand years.
Boris Worm says the findings are, in his words, “beyond anything we suspected.”But he also said the situation is not too late to core. He said that with good fisheries management, some species could completely recover in three to ten years.
【1】The two underlined words “their” in the first paragraph most probably mean .
A.researchers' B.fisherman's
C.sea foods' D.the oceans'
【2】Which of the following is true according to the passage?
A.All the scientists don't believe that all seafood species will disappearing very soon
B.Most government officials disagree to the seafood-disappearing research
C.Some scientists are doing a good job of protecting fish populations
D.It's too late to take any action to improve the situation.
【3】According to Boris Worm, .
A.Some people are doing a good job of protecting fish populations
B.Overfishing is one of the causes for the loss of seafood species
C.things are getting worse though efforts can be made
D.some more species will come into being with right measures
【4】What is the main purpose of the passage?
A.To call on people to protect the ocean environment
B.To introduce a study about the disappearing of sea foods
C.To report different opinions about the seafood research
D.To criticize the present fisheries management

You can count on the fact that cocoa bean planting is bad for the environment—especially for the rainforests of West Africa. That’s enough to make some consumers think about giving up chocolate. But what if we could enjoy chocolate without climate guilt? In fact, we can, because when cocoa is grown sustainably, it can actually help save the world.
Cocoa beans grow on shrubs that are often planted in the open but can also grow better under large rainforest trees. Well-managed shade-grown cacao trees can store a significantly higher amount of carbon than annual crops—up to three times the amount stored by cacao trees grown in full sun. Shade-grown cacao trees are also more drought-tolerant and weed-resistant than those grown in the open. They are friendlier to wildlife, improving biodiversity.
The problem is not that cacao trees can’t help the environment. The problem is that too few of them do. The reasons for this are complex, but mainly boil down to lack of resources, lack of information and insecure land tenure( 保 有 期 ). Many West African cacao farmers are sharecroppers. They can’t remove old, diseased trees because this would risk losing the land. They can’t afford to plant new trees, either. As a result, new cacao farms are usually created by businessmen who cut down trees and create chemical-intensive( 大 量 使 用 化 学 物 品 的 ) plantations, which both pollute and reduce biodiversity.
As the planet grows warmer and drier, though, these high-productive, full-sun cacao varieties are becoming weaker in the heat. Many small cacao farms in West Africa’s cocoa belt, which supplies up to 70 percent of the world’s cocoa, now suffer from low productivity. But there is hope. When cost and land tenure issues are solved, farmers are more than willing to grow cacao trees in the shade.
Trees are the most important weapons in the fight against climate change. So enjoy your chocolate—provided that it’s a sustainable, shade-grown brand. In fact, buy, eat and give as much of it as you like. The world will thank you.
【1】Which of the following can store the largest amount of carbon?
A.Local annual crops that grow near the water.
B.Cacao trees that grow in full sun.
C.Cacao trees that grow under the shade.
D.Newly planted cacao trees that have most leaves.
【2】What is the current problem according to the passage?
A.There are not enough cacao trees to take effect.
B.Pollution from chemical plants poisons cacao trees.
C.Only a part of the cacao trees can help the environment.
D.Local cacao farmers run chemical-intensive plantations.
【3】What is a possible solution to the low productivity of cacao farms in the cocoa belt?
A.Making improvement to cacao varieties by means of chemicals.
B.Encouraging farmers to grow cacao trees under rainforest trees through some supporting measures.
C.Providing shade for originally full-sun cacao trees in the warmer and drier region.
D.Inviting successful businessmen to manage cacao farms in West Africa’s cocoa belt.
【4】What is the best title for the text?
A.West Africa’s Cocoa Belt Is in Danger
B.Sustainable Brands Help Save the World
C.How Chocolate Can Help Save the Planet
D.How We Can Enjoy Food Without Climate Guilt

This season, the bushfires in Australia have burned more than 12.35 million acres of land. At least 25 people have been killed and 2000 homes destroyed. According to the BBC, this is the most casualties (伤亡) from wildfires in the country since 2009. The University of Sydney estimates that 480 million animals have died in South Wales alone.
Zeke Hausfather, an energy systems analyst and climate researcher at Berkeley Earth, said warmer temperatures and extreme weather have made Australia more susceptible to fires and increased the length of the fire season. “The drier conditions combined with record high temperatures in 2019 created main conditions for the disastrous fires. Australia’s fires were worsened by the combination of those two. 2019 was the perfect storm for being the warmest year on record for Australia and the driest year on record for Australia,” Hausfather added on Friday.
Kevin Trenberth, a senior scientist at the US National Center for Atmospheric Research, said warmer ocean temperatures also contributed to more variable weather around the world. Trenberth believes that global warming contributed to energy imbalances and hot spots in the oceans, which can create a wave in the atmosphere that locks weather patterns in places, causing longer rain events in Indonesia, for example, and at the same time contributing to drought in Australia. He said that once an area experiences drought conditions for two months or more, it increases the risk of fires catching and spreading. Those changing weather patterns due to global warming make drought events longer.
Climate experts stress that climate change is not the only factor in the severity of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled burns and other factors can impact the risk to people and property, such as warning systems and the type of development in a given area. Changing those policies has great potential to limit future damage from wildfires along with changes to how fire management resources are dispatched (派遣).
【1】What are the numbers about in Paragraph 1?
A.The causes of Australian fires. B.The results of Australian fires.
C.The damaged areas of Australian fires. D.The property destruction of Australian fires.
【2】Which of the following best explains “susceptible to” in the second paragraph?
A.Very quickly to adapt to. B.Very seriously to focus on.
C.Very easily to be protected against. D.Very likely to be influenced by.
【3】What can we infer from Trenberth’s research?
A.Warmer ocean temperatures promote fires spreading.
B.Longer dry weather contributes to global warming.
C.The imbalanced energy leads to the temperature rising.
D.Global warming is the root cause of the bushfires.
【4】What does the author intend to do in the last paragraph?
A.To provide some advice about reducing damage.
B.To show the methods for controlling burns.
C.To predict the seriousness of Australian fires.
D.To stress the effects of Australian fires.

It’s an argument that every modern parent has had with their child: the battle to break them away from the mobile phone they’re staring at. For children, a smartphone is a window to games, videos and constant interaction with their friends. But for parents, it can feel like a minefield. 【1】
First, it’s worth bearing in mind that screen time can be beneficial. “【2】But they often use them to develop an interest. For instance, if they’re interested in gymnastics, they’ll watch videos of routines and try to learn from them,” Peter Twining, professor of education at the Open University says.
【3】It may help to explain the substantial gap in opinion between children and parents about how much screen time is acceptable. According to a survey, the amount of screen time that adults thought appropriate for children was 1.75 hours, with children believing it to be 3.34 hours.
【4】However, recent research suggests that instead of setting specific time limits for usage, such as a maximum of two hours per day, it’s actually the nature of the screen time that matters. For instance, passively looking through social media posts is less beneficial than actively playing games, which can improve problem solving skills. A study found that “how children use the devices, not how much time they spend on them, is the strongest predictor of emotional or social problems connected with screen addiction.”
Twining agrees, saying: “I’m less concerned about screen time than about the nature of the interaction around the screen. The screen should become a shared focus for interaction with the family rather than an individual activity. The screen shouldn’t be an alternative to communicating with your child. 【5】”
A.It should be an improvement to it.
B.It’s a dilemma to judge which side outweighs the other.
C.A mobile phone is different from traditional land line phones.
D.But at least both parties do recognize that there should be limits.
E.Screen time counts down only during the time a child is signed in.
F.We tend not to recognize the value of what they do on their mobile devices.
G.We should emphasize the difference in understanding children’s mobile phone usage.

Ecology is a complicated thing. Given the facts that elephant damage often kills trees and bush fires often kill trees, it would be________to assume that a combination of the two would make things worse. Contrary to this assumption, ________, as the recently-published research by Benjamin Wigley shows, if a tree has already been damaged, fire can________help to make things better.
One common way in which elephants harm trees is by stripping(剥) them of their bark(树皮). Dr Wigley, who did indeed start from the obvious________, set off to find out how much worse bush fires would make the effects of this bark stripping. To serve this purpose, he set up a study in the Kruger National Park. Since 1954, the Kruger has been the site of experiments in which plots of land have been burned________, to understand the effects of fire on plain ecology. In these experiments, Dr Wigley looked at trees in three different zones, in one of which, the trees were burned every year; in the second, they were burned every other year, while the third zone, by contrast, was actively________fire. To keep things consistent, he looked at the fate of the same tree species, the marula(马鲁拉树), in all three zones. He picked marulas because they are particular________of elephant activity. Their fruit are delicious, and prized by elephants and people alike. But elephants also seem to enjoy eating their bark. In July 2016 he and his colleagues identified 20 marulas in every zone and used special tools to________from each of them a circular section of bark 5 cm in diameter. Having imposed this damage, they________the wounds over the course of the following two years, to see what would happen. To their________, they discovered that the wounds of trees in fire zones recovered far better than those of trees that had seen no fires at all. Wounded trees in the annual burn zone re-grew 98% of their lost________during the two years of the study. Those living in the biennial(两年一次的) burn zone re-grew 92% of it. But those in the zone where fires were________re-grew only 72%.
The researchers also found something else when they were measuring the trees’ wounds: ants. Ten of the 20 trees in the fire-prevention zone developed ant colonies in their wounds. The ants in question were a species that is known to damage trees and is supposed to________tissue healing. By contrast, only five trees in the biennial burn zone and three in the annual zone developed ants’ nests in their wounds. It looks, therefore, as if bush fires are treating trees’ wounds by killing ants that might________colonize and damage them. Though such fires are surely harmful to healthy trees, it seems, in an example of two negatives making a positive, as if they are actually________to sick ones.

阅读下面材料,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。
When a tornado(龙卷风) touched down in a small town nearby,many families were left completed ruined. Afterward all the local newspapers carried many human-interest stories featuring some of the families who suffered the hardest.
One Sunday, a particular picture especially touched me. A young woman stood in front of an entirely shattered(破碎的) mobile home, a depressed expression on her face. A young boy, seven or eight years old, stood at her side, eyes downward. Clutching(紧握) at her skirt was a tiny girl who stared into the camera, eyes wide with confusion and fear.
The article that went with the picture gave the clothing sizes of each family member. With growing interest, I noticed that their sizes closely matched ours. This would be a good opportunity to teach my children to help those less fortunate than themselves. I stuck the picture of the young family on our refrigerator, explaining their difficulty to my seven-year-old twins, Brad and Brett, and to three-year-old Meghan.
“These poor people now have nothing,” I said. “We’ll share what we have with them. I brought three large boxes down from the room upstairs and placed them on the living room floor. Meghan watched seriously, as the boys and I filled one of the boxes with canned goods and foods.
While I sorted through our clothes, I encouraged the boys to go through their toys and donate some of their less favorite things. Meghan watched quietly as the boys piled up old toys and games.
Meghan walked up with Lucy, her worn, much-loved rag doll hugged tightly to her chest. She came to the box that held the toys, pressed her round little face into Lucy's flat, painted-on-face, gave her a final kiss, then laid her gently on top of the other toys.
“Oh, Honey,” I said.” You don’t have to give Lucy. You love her so much.”
Meghan nodded seriously, eyes filled with held-back tears. "Lucy makes me happy, Mommy. Maybe she’ll make that other little girl happy,too.”
Paragraph. 1:
The boys had watched,open-mouthed,as their baby sister placed her favorite doll in the box.
