Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.

The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases.

Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.

Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.

People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.

1.What is the main cause that people suffer from a lot of new sicknesses?

A. Ancient people did a great deal of physical exercise.

B. People today have a lot of alcohol.

C. People today have more tobacco.

A. the human body has changed compared with humans who first appeared on the earth

B. the way we live has changed a little

C. our body can’t deal with the changes in life style

D. the way we live today is proper for the human body

4. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________.

Heat has been used to control hair for hundreds of years. But how much is too much? If you have ever opened a very hot oven, you know that heat can burn your eyebrows off your face very quickly. A scientist from Purdue University in Indiana is trying to find a scientific answer on how hot is too hot when it comes to your hair.

Many women and some men are very particular about their hair. Some people who have naturally curly hair prefer to have it straightened. Others with straight hair want to have curls. Tahira Reid is one of those people. As an African-American woman, she is familiar with the challenges of maintaining (保养) curly hair.

Tahira Reid and other researchers at Purdue University are studying how heat treatment interacts with different types of hair and how to prevent damage. Amy Marconnet is an assistant professor. She says the team is seeing how heat and temperature relate to their research.

In a Purdue University’s lab, team members designed a hair straightener tool —a flat iron with temperature control. They attached it to a robotic arm that moved over pieces of hair. They controlled the temperature while the device straightened hair.

What did they find? Their study found that the heat weakens or breaks a protein called keratin, responsible for the hair’s shape, and temporarily changes it. But nobody knows exactly what level can make the heat actually cause forever change. Researchers say early results are a bit inconclusive.

It turns out that everyone’s hair is different and there’s no exact temperature where hair straightening becomes hair damage. Ms Reid says they will continue their research in the hope of finding what works best without damaging hair.

1.What does the scientist want to find out?

A. Ways to protect our hair.

B. Ways to maintain curly hair.

C. The temperature that can damage hair.

D. The temperature that makes hair curly.

2.The underlined part “those people” in Paragraph 2 refers to those who ________.

A. are African-Americans

B. love their hair very much

C. love making their hair curly

D. love changing their hairstyle

3.When the heat breaks a protein called keratin in the hair, ________.

A. the hair gets burned

B. the hair’s shape is changed

C. the hair is forever damaged

D. the hair surely becomes curly.
