A The earliest tomatoes were little sour berries。 They grew among low bushes in dry, Sunny places in the Andes Mountains in South America it was about 350 million years ago. Tomato plants are relative to nightshade (茄属植物), which has poison The leaves and stems of tomato plants have poison, but the berries are good to eat. The berries are red so that animals can find them easilyand eat them. The animals carry the seeds to other places. That was how earliest tomato plants found new places to grow. Tomatoes are also relative to tobacco, chili peppers and potatoes. When people hint Came 10 South America about 20.000 years ago, they ate these tiny wild tomatoes. Travelers brought a few kinds of wild tomato plants from the Andes to Central America. There the ancestors of the Maya began to farm them. Nobody knows exactly when people began farming tomatoes, but it probably was much later than com and beans, and it was surely before S00 BC . These Central American farmers bred tomatoes to be bigger and sweeter than the wild ones. By the time Spanish explorers got to Tenochtitlan in Mexico in 1521 AD, the Aztec people were eating a lot of tomatoes They made a Sauce of chopped(利碎的) tomatoes onions salt and chili peppers that was a lot Iike our salsa. The word"tomato" comes from their Nahuatl word"tomatl”.

Because tomatoes weren't farmed until pretty late, farmers further north had not yet been able to adapt their growing season to working in North America. Even today, it's pretty hard to get your tomatoes ripe in the northern parts of North America before the growing season ends. ( ) 1. What do we know about the earliest tomatoes? A. They were big sweet berries. B. They grew in Central America C They grew in dry, sunny places. D. They grew about 35 million years ago. ( ) 2. How did the earliest tomato plants grow in new places? A. People grew them in new places. B. They grew in new places naturally. C. Their seeds were carried away by wind. D. Their seeds were carried away by animals. ( ) 3.What happened after tomatoes were brought to Central America? A. The farmers sold them to others. B.The farmers disliked their taste. The farmers tried to improve them. D. The farmers showed no Interest in them. . ( ) 4. What is the text mainly about? A. How to grow tomatoes. B. The history of tomatoes. C. When to grow tomatoes. D. The places where tomatoes grow. B The Mexican blind cavefish does not have eyes, but it can "see”obstacles in dark caves by wrinkling its mouth and producing bursts of suction (抽吸), according to a new study. The research describes this unique form of navigation for the first time. Scientists previously thought the eye-less Mexican cavefish navigated by sensing changes in water pressure produced by waves sent out from the fish's own body. But when the researchers examined the fish, they found some problems with this explanation. For example, larger fish, which would likely produce larger waves, should be able to identify objects from farther away than smaller fish. In fact, larger fish detected objects at about the same distance as smaller fish did. Researchers at Tel Aviv University in Israel decided to survey the sightless navigation further, conducting an experiment in which they counted the number of times the fish opened and closed their mouths when being near objects the fish were familiar with. The researchers then moved the objects and observed changes in the fishes' mouth movement in the unfamiliar environment. The fish opened and closed their mouths more than twice as frequently in unfamiliar surroundings, and more frequently when approaching an object than in the open, with no objects nearby, suggesting this behavior plays a role in detecting the fish's environment. Through further analyses, the team determined the suction sent outby this mouth motion produces a signal similar to echolocation (回声定位) ----a system in which animals, like bats and dolphins, emit sound waves and detect the distance of an object based on how long the sound takes to bounce back. Instead of measuring time, however, the cavefish appears to measure the pressure change produced by its mouth suction. The study findings were detailed last week in the Journal of Experimental Biology. ( ) 5. What can we learn from Para. 2? A. The larger the fish is, the further it can detect B. The larger the fish is, the closer it can detect. C. The smaller the fish is, the closer it can detect. D. The fish, large or small, can detect objects at the same distance. ( ) 6. Why did researchers at Tel Aviv University do the experiment? A. To observe the cavefish more carefully. B. To find out the fishes' mouth movement. C. To research on this unique navigation further. D. To compare the cavefish with bats and dolphins. ( ) 7. What does the cavefish do when it approaches an object? A. It stops swimming and changes its way. B. It opens and closes its mouth more slowly. C. It may hit the object and then turn away. D.At opens and closes its mouth more frequently. C On an ordinary weekday evening, Jane was at home as usual. As she was considering what she was going to do with her dinner plans for the evening, she was unexpectedly interrupted by an urgent call from her sister,“get over here!”

A few hours later, Jane found herself with 8 strangers in the middle of the boiling desert heat of Utah, picking up rubbish and raising awareness about zero waste and climate change. Armed with a deep love of the environment and a desire to make a difference, Jane, Davey, and a group of self-described "environmental pick-up artists” went on a road-side rubbish pick-up. As they walked, sometimes only covering 0.9 miles in an entire day, they slowly and steadily made their way across the United States, picking up a total of 201 ,678 pounds of rubbish. In the end, three years and 3,672 miles later, they dipped their feet in the cold waters of the Pacific. The road is winding, often up-hill.“With a rubbish bag as your companion, how do you remind yourselves that picking up that tiny gun wrapper on the ground makes a difference? Where do you find the strength to keep going?" As I asked Jane and Davey to answer these questions, they shared remarkable stories of caring environment that gave their efforts to continue their journey. A small group of us were lucky enough to spend two hours last Wednesday evening listening to the remarkable stories of Jane and Davey. As they shared their deep concern for the environment, we together experienced their real spirit Jane and Davey, like so many ordinary unknown heroes in our community, might not ever draw much attention like multi-million-dollar-funded projects. In many ways, it is exactly that which makes their story so attractive. ( ) 8. Why did Jane's sister call her out? A. To ask her to prepare dinner for them. B. To beg her to help them out of trouble.

C. To ask her to join them in their activity. D. To ask for advice on picking up rubbish. ( ) 9. How did the group travel across the United States to gather rubbish? A. By bus. B. on foot. C. By train. D. By bike. ( )10. What gave them the courage to go on their journey? A. Good teamwork spirit. B. Great interest in traveling. C.,Deep love of natural beauty. D Deep concern for the environment. ( )11. Which of the following can best describe Jane and her teammates? A.Ordinary people have done extraordinary things: B. Their effort will stop nature from being polluted. C. Their action is wiser than environmental projects. D. They are famous heroes of environmental protection. D It is an unlikely collaboration (合作): She is a fashion designer whose creations have been won by Madonna, Rihanna and Katy Perry while he is a world-famous chemist. But together, Helen Storey and Tony Ryan are combining style and science to create clothes that clean the air webreathe. Their“Catalytic Clothing”makes use of existing self-cleaning technology found in paints and glass which employ photocatalysts (光催化剂) to break down harmful air pollutants污染物) like that given out by cars and factories. Applying it to clothing is creative though, and potentially far more effective, says Ryan, a chemist at the UK'S University of Sheffield. Some rough calculations showed that his suit has a surface area of about 80 square meters.“We already knew that we could get self-cleaning windows and paints. But I thought if I put a catalyst on that surface I can do a lot of environmental clean-up,"Ryan said. When ultraviolet light(紫外线) hits it, it causes pollutants to break down into non-harmful chemicals. “We found out, rather wonderfully, that the catalyst works particularly well on jeans," Storey added while pointing out that there are more pairs of jeans than people on the planet. Ryan added that a pair of jeans weighing 500 grams could absorb around two grams of pollution. Ryan and Storey say more testing needs to be done, but they're confident a product could be on the market within the next two years. ( )12. Which of the following is true of Catalytic Clothes? A.They are able to make air clean. B. They could keep clean for a long time. C. They are designed for famous people. D. They have been worn by many people. ( )13. Catalytic Clothes will not work effectively when_______. A.they are in a dark place B. there are so many cars around C. the surface is less than 80 square meters D. they are exposed to too much strong light ( )14. Para. 4 is mainly used to show________. A. people have a preference for jeans B. the new technology will make jeans lighter C. people should be encouraged to wear more jeans D.“Catalytic Clothing" will benefit the environment a lot

( )15. What is the best title for the text? A. New Tech Promotes Clothing Industry B. A New Way to Deal with Clothing Pollution C. Clothes Can Mean a Lot to the Environment D. Famous People and Environmental Protection 完形填空
