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(內(nèi)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 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 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(糖尿病). 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 shortcut. Exercise has to be an important part of your lifestyle.” Bell said.

1.What is the passage 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 don’t have diabetes.

2.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.

3.From the last paragraph, we can find that ______.

A．internal fat leading 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

4.The underlined part in the last paragraph means ______.

A．a(chǎn) long road

B．a(chǎn) clear difference

C．a(chǎn)n easy way

D．a(chǎn) short distance

The latest fashion in kitchen is the food steamer． All the stores are selling them; everyone wants one． Steaming is one of the simplest and healthiest ways of cooking food．However, that cooking time is usually longer than with other methods． In case you’re thinking of buying a steamer, I've done a survey about the steamers available on the market to help you decide which will suit you best．

●Folding Steamer

The simplest and least expensive is the folding stainless-steel （不銹鋼）version．

Advantages: This is a good, basic design which sits inside a variety of different shapes of pans with the water under it; a ring in the center allows for easy lifting and it's easy to clean．

Disadvantages: It only holds small dishes． Also, if you put too much water in the pan, it will boil up through the vegetables and they will be watery． If you put too little water in and let it get dry, you will burn the pan and get strange-smelling vegetables．

●Steaming Pan

This is a three-layered black Teflon-coated version with a lid and two double-handled steamers, which sits on the oven ring． The brand I bought is called Nutritious Living．

Advantages: This is an excellent steamer, lightweight, easy to clean, and of all the steamers I've tried, this cooks the fastest． Fish and chicken can be cooked on the bottom with rice or vegetables on the top． It's easier to store．

Disadvantages: Water can boil away until the pan is dry, but if you make sure you fill the pan up to the suggested level and do not overcook the food, this should not happen．You cannot see the food cooking from the top． It doesn't supply a dish for cooking rice．

For serious users of steamers, I recommend having one of each version． If you just want to try it, get the folding stainless-steel type．

1.Why did the author carry out the survey?

A．To inform people of different steamers

B．To run an advertisement for steamers

C．To find out a suitable steamer to buy

D．To learn how to cook with steamers

2.What can we learn about the folding steamer?

A．It comes in different kinds of shapes and sizes．

B．It is designed for large families．

C．It is able to clean itself．

D．It is easy to take out．

3.The Nutritious Liuing steamer ．

A． is more difficult to store

B． provides a dish to cook rice with

C． cooks different foods at the same time

D． cooks fish and chicken faster than vegetables

4.According to the author, you should ．

A． use steamers to save cooking time

B． buy a steamer with dishes supplied

C． do a survey before choosing a steamer

D． buy a folding steamer if you want to try
