Do you want to improve your physics and chemi...

Do you want to improve your physics and chemistry grades? Well, maybe you should first learn something about the struggles(奋斗) of great scientists.

The American Psychological Association did an interesting study. More than 400 students from schools in New York City took part in it. The students were divided into three groups. Group 1 read a typical textbook that describes the achievements of great scientists. Group 2 read about those scientists' personal struggles. For example, as a Jew, Einstein ran away from Nazi Germany to avoid persecution(迫害). The last group read about the scientists' intellectual struggles. These stories about struggles also told students how the scientists dealt with these obstacles(障碍).

The students took a science exam before the study. After the six­week study, they took another. Scientists found those in Groups 2 and 3 improved their science grades. Students in Group 1 didn't see a grade increase. Some of them even had lower grades after the study.

The study was led by Xiaodong Lin­Siegler, a teacher at Columbia University. According to Xiaodong, kids often think Einstein was truly intelligent. They believe they will never match him. Many of them fail to realize that any success requires a long journey. Along the way, there are many failures.

Students who read the struggle stories more probably said that great scientists were like themselves. The "great minds" also had to overcome obstacles to achieve success.

Xiaodong thinks textbooks should include more stories about how great scientists had to struggle to succeed. And students should focus more on how these scientists dealt with the obstacles they met along the way.

1.According to the passage, students can improve their physics and chemistry grades by ________.

A.reading the achievements of great scientists more carefully

B.listening more carefully to their physics and chemistry teachers

C.learning about how great scientists dealt with their obstacles

D.doing more physics exercises and correcting mistakes

2.All of the students who took part in the study ________.

A.were interested in physics and chemistry

B.went to schools in New York City

C.wanted to improve their physics and chemistry grades

D.didn't like physics at all

3.The underlined word "match" in Paragraph 4 means "________".

A.satisfy B.catch C.hate D.like

4.Xiaodong Lin-Siegler thinks science textbooks should ________.

A.tell students directly that Einstein was born a common man

B.make the long lists of facts that students have to remember more interesting

C.include more stories about how great scientists had to struggle to succeed

D.tell students that great scientists have better families

5.What does this passage mainly talk about?

A.Students should learn something about the struggles of great scientists.

B.Success can be easily got by everyone.

C.Students should read more books to improve their grades.

D.An interesting study led by Xiaodong Lin-Siegler and his views.

Five tips for safe running

We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.

Running is good exercise, but it can be hard on the body. Here are five ideas to reduce (减少、 降低)the risk of injury (受伤).

1. Do not run too much, too soon or too fast. Most people get running injuries when they push their bodies too bad. The body needs time to get used to increase in distance or speed. Muscles and joints (关节)need time to recover.

2. Most running injuries do not come unexpectedly. Usually, there are warning signs. They may include body aches, sore muscles and pain that does not go away.

3. There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should change your shoes every 500 to 800 kilometers.

4. Take time after each run to write down what you did and how you felt. Look for patterns, things that happen over and over again. These notes will help you find the best exercise for you.

5. As we said earlier, running is hard on your body. So physical fitness experts suggest some form of cross training to improve muscle balance and to help you stay injury free. They say swimming, yoga, and riding a bicycle are good exercises to combine (结合)with running. These exercises are easier on the body.

A.Train properly

B.Go on a diet

C.Listen to your body.

D.Take it easy.

E.Take good notes.

F.Get good running shoes.
