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.

A Different Kind of Spring Break

For many American university students, the weeklong spring break holiday means an endless party on a sunny beach. In Panama City Beach, Florida more than half a million university students arrive during the month of March to play and party, making　　　　　 it the number one spring break place in the United States.

A weeklong party is not for everyone, however, and a growing number of American university students have found a way to make spring break matter. For them, joining or leading a group of volunteers to help solve problems such as homelessness or environmental　　　　　 damage makes spring break a special learning experience that university students can feel good about.

During one spring break week, students from James Madison University in Virginia took part in 15 “spring break” trips to nearby states, three others to more distant parts of the United States, and five international trips. One group of JMU students　　　　　 traveled to Bogalusa, Louisiana, to help rebuild homes damaged by Hurricane (飓风) Katrina. Another group traveled to Mississippi to organize creative activities for children living in a homeless shelter. One group of students did go to Florida,　　　　　 but not to lie on the sand. They did some work to help protect the native Florida plants.

Students who take part in spring break projects find them very rewarding (值得的). While most university students have to get their degrees before they can start helping people, student volunteers are able to help people right now without degrees. On　　　　　 the other hand, the buildings or rooms they live or stay are far from attractive. Students often sleep on the floor of a school or church. But they only pay around $250 for meals and transportation, which is much less than some of their friends　　　　　 spend traveling to more traditional spring break hot spots.

Spring break projects appear to be growing in popularity at universities across the United States. Some students take the opportunity to meet new friends. Others want to exercise their beliefs to make the world a better place. Whatever their reasons,　　　　　 these students have discovered something that give them rich rewards along with a break from school work.

1.What's the number one spring break place in the United States?

2.What is the way to make spring break matter for some students?

3.How did the students help in Bogalusa, Louisiana?

4.Where do the student volunteers often sleep?

5.What makes the spring break projects more rewarding?

When you do your homework, you may often meet some problems. How do you solve them? Tom, a middle school student, would take out his smart phone, open a special app（应用）and search the problem. Answers soon appear on the screen.

Nowadays, many students do homework with the help of the special apps like Tom. "It's convenient. You don't have to go out or wait for a tutor（家庭教师）at home," Tom said. "You also learn by seeing how others work them out. It’s very helpful and improves students' abilities." said John, another student. He said it was especially true for new types of homework.

John's Chinese teacher often asks students to give speeches on great writers. When it comes to John's turn, he usually searches online, picks out certain stories and makes PPTS（演示文稿）. "I've become skilled at finding information online and using Microsoft Office." John said.

However, many people think this trend（趋势）also brings up problems. Some students just copy the answers online without thinking. They become lazy.

Head teacher Mr. Wang in Tom and John's school thinks that knowing how to use the Internet is important. The key is to have good self-control. "No matter how difficult the problem is, think about it by yourself first. Remember not to depend on the Internet too much." the teacher said. "Be sure to understand the reasons behind the answers, or you won't make progress. If you don't have confidence in your self-control, ask your parents for help."

根据短文内容判断对错，对的为“T”，错的为“F”。

For some students, getting better grades can seem like an impossible task sometimes. With the challenges（挑战）of school, just paying attention in class or studying hard isn’t always enough. But what if there were other ways for students to improve their grades? For parents and students who have ever wondered if this is possible, now you can rest easy. Research suggests that a person who likes doing activities can improve their grades.

Scientists think that those students who are active are not just exercising their bodies, but also exercising their brains（大脑）. In turn, they can be able to improve their grades at school.

In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing（组织）their schoolwork as well as doing project work and learning traditionally “difficult” subjects, such as maths.

What does this mean for children who aren’t active? Researchers think that if kids don’t get enough activities, they are going to be at a disadvantage when it comes to school performance.

In the research experiment, a group of children skipped with ropes（跳绳）, played basketball and did a number of other games or exercises. Another group of children didn’t do any activities. They took part in testing both before experiment and after the experiment. Testing was mainly for maths and reading skills. Results showed that the children in the activity group did better on the tests than those who had no activity.

All work and no play will not only make Jack a dull（迟钝的）boy, but will also negatively（消极地）affect his grades in school, according to a new study published in the Journal of Pediatrics.

Parents complain（抱怨）children today are actually less active and they always worry about their grades. Dr. Belton, an expert, said,“If you’d like to see your kids do better in school, have them close their books, set down their pencils and go outside to play.”

1.What does the underlined words “rest easy” in Paragraph 1 mean?

A.Stop worrying. B.Keep working. C.Continue learning. D.Study hard.

2.What kind of children is better at organizing their schoolwork in the most recent study?

A.They study all the time.

B.They play for half an hour every day.

C.They finish their homework on time.

D.They do some reading after class every day.

3.In Paragraph 5, what does the research experiment want to show us?

A.Doing activities is bad for the students.

B.Doing more homework can get better marks.

C.The children in the activity group did better on the tests.

D.Children who didn’t do any activities did better on the tests.

4.Where is the text most probably from?

A.A sports magazine. B.A science book. C.A guide book. D.A history book.

While the start of a new school year is always exciting, this year was even more so for some students at White Cloud Primary School. They became the world's first kids to be taught by an electronic teacher. This electronic teacher is not a human­like robot walking around the classroom. Instead, he is a computer­created head that appears, when needed, on students' computer or phone screens. His name is Bill.

Created by technology company Smart Machines, Bill is able to show human­like behavior. He is designed to teach a special program about environmental­friendly power created by the sun and wind. This program, started in 2005, used to be taught by human teachers.

Just like human teachers, Bill is able to immediately respond to the students' questions and opinions about the topic. Thanks to computer cameras, he is also able to see and react to students' physical actions. For example, if a student smiles at Bill, he responds by smiling back. This two­way exchange helps get the students' attention. More importantly, it allows the program developers to improve Bill's behavior and knowledge base when needed.

The program has been a great success, according to Smart Machines spokesman Robert Frost. Frost says, “What is interesting to me is the children's reaction to Bill. He really attracts their attention.” Frost thinks kids don't find the experience of being taught by smart machines as strange as older people because they have grown up in a time of computers and smart phones.

It is doubtful, however, that human educators will lose their jobs to Bill any time soon. For one, this talking head's knowledge base is not large. More importantly, even the smartest computer programs can't guess and react to all the unexpected situations that educators face daily. Bill's future might be as a “personal tutor”， providing kids with one­on­one help for different subjects and topics.

1.What is Bill?

A.A human­like robot.

B.A kind of computer game.

C.A computer recording tool.

D.A computer­created talking head.

2.How does the two­way exchange help the program developers?

A.It lets them correct students' mistakes.

B.It allows Bill to respond more quickly.

C.It helps them know how to improve Bill.

D.It helps them study students' body language.

3.What does the word “they” refer to (指的是)?

A.Kids. B.Older people.

C.Smart machines. D.Program developers.

4.What is Bill NOT good at doing?

A.Attracting students' attention.

B.Understanding students' body language.

C.Responding to students' questions.

D.Dealing with unexpected situations.

5.How might Bill be used in the future according to the last paragraph?

A.To work as human classroom teachers.

B.To encourage students' interest in computers.

C.To give students personal help with different subjects.

D.To watch over the behavior of the students in the classroom.
