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

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.

Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.

Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.

The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.

To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.

1.It can be inferred from Para. 2 that __________.

A. foods with natural enzymes help people keep fit

B. we’d better be cautious about raw and whole foods

C. it is essential for people to protect their vital organs

D. giving up cooked and refined foods is a new lifestyle

2.Processed foods are unhealthy because they __________.

A. destroy body’s cells B. stop body’s metabolism

C. may lead to obesity D. are difficult to digest

3.What is the main purpose of this passage?

A. To warn people of the problem of obesity.

B. To advocate eating more raw and whole foods.

C. To inform people of the harm of processed foods.

D. To tell the differences between raw and processed foods.

4.The underline word “vicious” in the last paragraph probably means ____________.

A. violent B. progressive C. positive D. harmful
