【题目】Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. “What we saw was that the more diet sodas a person drank, the more weight they were likely to gain, said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

While the findings are surprising,they also offer some explanations.

Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. “We weren't seeing weight loss necessarily, and that was confusing to us, said Rogers.

So why would diet soda cause weight gain? No one knows for sure yet,but it could be that people think they can eat more if they drink diet sodas, and so over-compensate(弥补) for the missing calories.

A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. “Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky, said Helen P. Hazuda, professor at School of Medicine of the University of Texas. They may be free of calories, but not of consequences.”

【1】People drink diet sodas to________.

A. enjoy its taste B. stay in fashion

C. achieve weight loss D. gain more energy

【2】We can learn from the passage that________.

A. regular sodas make people lose more weight

B. diet soda drinkers tend to eat more food

C. diet sodas do help reduce calories

D. most blood diseases come from diet sodas

【3】The underlined word “They” in the last paragraph probably refers to“________”.

A. sweeteners

B. diet sodas and artificial sweeteners

C. sodas

D. diet soda drinkers and sweetener takers

【题目】In 1985, a lionfish was caught off the coast of Florida. Now they can be found not only in the Atlantic Ocean but also in the Gulf of Mexico and the Caribbean Sea. And they are continuing to move south. Lionfish are native to the Indian and western Pacific Oceans. So how did they end up in the Atlantic? Scientists believe some pet owners abandoned their unwanted lionfish and poured them into the sea. Little did they know the trouble their actions would cause.

The Atlantic Ocean turned out to be a comfortable home for lionfish. Their venomous spines (毒刺) protect them from sharks and other fish. Female lionfish can spawn (产卵) every few days, producing as many as 2 million eggs per year. Other big fish would have competed with lionfish for food. But overfishing has removed many of these large fish. As a result, the fish have eaten so much that they have grown to be more than three times the size of their cousins in the Pacific and Indian Oceans. “They eat mostly fish,” says Stephanie Green, a scientist at Oregon State University.

All that eating has caused great changes. Scientists have found that when lionfish are present somewhere, many other fish, which are small enough for them to eat, disappear. Some of the fish they eat are greatly missed in their habitats. For example, parrotfish eat certain plants off corals (珊瑚), which allows corals to grow better. But they are now disappearing due to lionfish.

Scientists say lionfish are here to stay. But there are ways to deal with the problem. The key, says Green, is to keep lionfish numbers in check. In Florida, divers can now go through a special training program and get certified (授予合格证书) to catch lionfish in areas where fishing is not usually allowed. And a number of restaurants have added the fish to the menu. “It’s going to be a long-term battle, but the missing sea species will come back someday,” says Green.

【1What can we learn about lionfish?

A. Its population is growing very quickly.

B. All of them are almost the same size.

C. They eat other big fish and even sharks.

D. Most of them have gathered in the Atlantic.

【2Parrotfish were mentioned to show lionfish’s _____.

A. loneliness B. carelessness

C. weakness D. harmfulness

【3】What is Stephanie Green’s attitude towards the battle against lionfish?

A. She doubts it.

B. She is hopeful of it.

C. She is worried about it.

D. She thinks it is against the law.
