【题目】（London）—If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.

Some doctors now think that the internal( 内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.

“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI（核磁共振） machines to create “fat maps” showing where people store fat.

According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits （沉积）of internal fat, even if they are slim.

Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.

According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.

Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body’s communication systems.

The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.

【1】What is this piece of news mainly about?

A. Thin people may be fat inside.

B. Internal fat is of no importance.

C. Internal fat leads to many diseases.

D. Thin people also have troubles.

【2】Doctors have found _____.

A. the exact dangers of internal fat

B. internal fat is the cause of heart disease and diabetes

C. being slim is not dangerous at all

D. being slim doesn’t mean you are not fat inside

【3】According to the passage, which of the following is WRONG?

A. Exercise can help to reduce the internal fat.

B. People can get rid of internal fat by improving diet.

C. Men are more likely to have too much internal fat.

D. People with heart disease all have internal fat.

【4】From the last paragraph, we can find that _____.

A. whether internal fat can lead to disease has been proved

B. exercise plays an important role in people’s life for keeping healthy

C. thin people usually have internal fat even if they are slim

D. it is easier to burn off internal fat than external fat

【5】The underlined part in the last paragraph means _____.

A. a long road B. an easy way

C. a clear difference D. a short distance

“They’re going to kick me out of my own home,” said Karl Berger, 86 years old. Karl is a widower with no living children. When Karl’s wife died a couple of years ago, he told the Social Security Administration to stop monthly checks to his wife. But the agency to send the checks. Karl called again; a clerk said not to 33 . He told Karl to mail a follow-up that included his wife's of death. But the checks continued to come. Karl needed the money, he cashed his wife’s checks.

When SSA realized its mistake, it sent Karl a letter saying that he SSA $5,900 plus interest. Karl receives only $12,000 a year, which is slightly poverty level. The only that he ever had--$5,000--was on his wife’s funeral. He fought on Iwo Jima, site of one of the most furious battles of World War II. The battle left him in one ear and almost blind in one eye.

His small house used to be in a good neighborhood. He takes the bus once a week to visit his wife's . The rest of his time is spent at home, where he carves military figures that he donates to a local charity. The charity the carvings and uses the money to help feed the homeless.

SSA gave Karl six months to pay the debt in . Otherwise, the SSA letter said, the agency would seize his home. Karl wrote back, asking if it would be okay to $30 a month. That was all he could .

“That’s insufficient,” said William Shatner, an SSA agent. “We know that he is a war veteran, but that doesn’t entitle him to . He knew that his wife was dead, yet he cashed her monthly . That is fraud, pure and simple.”

Many areas of cropland in Bangladesh(孟加拉国) are becoming unfit for farming. The land is becoming salty. It is a big problem for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

Farmers in the country are learning to grow vegetables in so-called "vertical gardens." The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain.

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

Villagers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12-$13 to build.

The village of Chandipur is in southwestern Bangladesh. Pumpkins and other gourds(葫芦) grow on vines on top of small homes. The vegetables get the food they need from soil placed in containers on the ground.

Shobitha Debna is a 35-year-old farmer in the village. Her garden space is very small. But she is able to grow hundreds of kilograms of vegetables each season.

She says she grows gourds, including pumpkin, as well as green beans, red amaranth, beets, carrots, cauliflower and more.

Ms. Debna depends on the vegetables to earn money. She makes a few dollars a day.

This kind of farming is new in Chandipur. But it may spread across the country.

A. the soil has been polluted

A. because there is much less salt in the soil

B. because there is much salt in the soil

【3】From paragraph 4, we can learn that_______?

A. vegetables with long roots grow in the sides of the containers

B. vegetables with short roots grow out of the small holes in the sides of the containers

C. vegetables with short roots grow on top of the container

D. vegetables in vertical gardens are not productive

【4】Ms. Debna grows many kinds of vegetables EXCEPT________.

【5】What can we infer from the passage__________?
