Everyone has done experiments in high school laboratories,but have you ever thought about designing a satellite to explore space?

On Nov.19,a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite.

The first satellite designed and built by high school students was sent up into space along with a record setting.28 other small ones on a rocket were sent from a NASA center in Virginia,CNN reported. It took the students seven years to build.

The students call their tiny satellite TJ3Sat,which is named after their school.It is just 10x10x12 centimeters and weighs only 0.89 kilograms,according to Orbital Sciences,a company which developed the rocket and supported the students’ project.It can be controlled with a smartphone.

Like most satellites,TJ3Sat can send and receive datA. The small spacecraft is equipped with a voice synthesizer (合成器),which can switch text to voice and transmit those sounds back to Earth over radio waves,said Orbital officials.In this case,anyone can give it a try via the project’s website (school website) by submitting (提交) a text.The texts that get approved will be sent to the satellite,changed to voice and then broadcast back to Earth via radio waves.

“I can say ‘Go Colonials’on our ground station and when it is on the other side of the world,in India,someone can hear‘Go Colonials’over the radio,”the team explains on the website.

The satellite will stay in space for at least three months.

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time.Later it became a research project for a select group of seniors.

At a time when American students are busy with SATs,the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities,Glazer said.

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro,program executive (主管) for small spacecraft technology at NASA,said in a statement.“I think we might be seeing kids saying what they want to do is build a spacecraft.The idea here is that they really can do that.”

1.The underlined word “awed” in the second paragraph is closest in meaning to _____.

A. influenced

B. amazed

C. delighted

D. inspired

2.Which of the following statements about TJ3Sat is TRUE according to the article?

A. It took a group of students about a decade to build the satellite.

B. Besides TJ3Sat,28 other small satellites were built by the students.

C. TJ3Sat can receive text messages that the students send into space,which can be changed to voice messages and broadcast back to Earth.

D. TJ3Sat is expected to stay in orbit for the next year,sending out messages together with information about its position in space.

3.According to the article,the launch of the satellite _______.

A. is evidence of the advance of spacecraft technology

B. proves that hard working teenagers can achieve a lot

C. shows the importance of extracurricular activities at school

D. has inspired many people to take an interest in space travel

People hold different views on what or how much homework should be. It is partly due to(由于) the fact that people can’t seem to agree on the purpose of homework.

Some teachers think that homework is necessary to reinforce (巩固)what is learned in school. And so they ask their students to memorize what was discussed in class through homework. Some teachers think the point of homework is to cover material that the class didn’t have time to get to, so their homework is to let students learn additional things. Other teachers like homework simply because they want students to form work habits and still others believe homework is necessary because it’s the best way for parents to learn what their children do in school.

However, many parents seem to have different ideas. Elisa Cohen, who has twins at Lafayette Elementary School, doesn’t like the fact that third-grade students in DC elementary schools are asked to write about 25 book summaries a year. She said, “They do the same thing over and over without really getting into alternate (交替的) ways of thinking about books, reading and writing.”

Some education reformers (改革者), such as Howard Gardner, a Harvard University professor well-known for his theory on multiple intelligence, think that Cohen is on the right track. But it’s often hard to persuade overworked teachers to give much thought to homework tasks.

1. How many opinions do the teachers have on “homework”?

A.3.B.4.C.5.D.6.

2. According to the experts’ opinions, ___________.

A. what Cohen’s thinking about is correct

B. teachers shouldn’t work too hard or too long

C. teachers should give necessary work to the students

D. teachers should let the students repeat what they didn’t have time to get in class

3.What’s the problem with Elisa Cohen’s twins in writing about their book report?

A. They find homework really hard.

B. They simply copy one repeatedly.

C. They get different ways of thinking about their work.

D. They aren’t given much thinking about what they read.

4.Some education reformers think we should improve our school education by_____.

A. increasing homework B. changing schools

C. changing teachers D. reducing homework

科目:高中英语 来源:2015-2016学年青海西宁十四中学高二上学期期中英语试卷(解析版) 题型:阅读理解

Down-to-earth means being honest, open, and easy to deal with. It is a pleasure to find someone who is down-to-earth. A person who is down-to-earth is easy to talk to. He or she accepts others as equals. A down-to-earth person may be an important member of society, of course, but they do not let their importance go to their heads, and they do not consider themselves to be better than others who are less important. Someone who is filled with self-importance and pride, often without cause, is said to have his nose in the air. There is no way a person with his nose in the air who can be down-to-earth.

Americans use another expression that is similar in some way to down-to-earth. The expression is both feet on the ground. Someone with both feet on the ground is a person with a good understanding of reality. He has what is called common sense. He may have dreams but he does not allow them to block his knowledge of what is real. The opposite kind of person is one who has his head in the clouds. A man with his head in the clouds is a dreamer whose mind is not in the world. Sometimes such a dreamer can be brought back to reality; sharp words from the teacher, for example, can usually get a daydreaming student to put both feet back on the ground.

The person who is down-to-earth usually has both feet on the ground. But the opposite is not always true. Someone with both feet on the ground may not be as open and easy to deal with as someone who is down-to-earth. When we have both our feet firmly on the ground, we are realistic and we act honestly and openly toward others, and our lives are like the ground below us, solid and strong.

1.If a person has both feet on the ground, he ____.

A. is in touch with reality, and doesn’t have any dreams

B. has some dreams but he is realistic

C. is honest, open and easy to deal with

D. is honest, open but hard to deal with

2.From the second paragraph, we know that sharp words from a teacher can usually ________.

A. help a student get down to the earth

B. wake a student up

C. help a daydreaming student come down

D. help a daydreaming student to become more realistic

3.The underlined sentence “But the opposite is not always true.” most probably means that ______.

A. the person who has his nose in the air is not true

B. a man with his head in the clouds is often not intelligent

C. the opposite direction is always wrong

D. a person who has both feet on the ground may not be down-to-earth
