【题目】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.”

1Which 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.

2According 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

【题目】You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.

The lift becomes this interesting social space where etiquette(礼仪)is sort of strange, Gray told the BBC. They are socially very interesting but often very awkward places.

We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, liftusers unthinkingly go through a set pattern of movements. He told the BBC what he had observed.

He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.

If there are two of you, you go into different corners, standing diagonally(对角线地)across from each other to create distance.

When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.

New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.

Why are we so awkward in lifts?

You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”

In such a small, enclosed space it becomes very important to act in a way that cannot be construed(理解)as threatening or strange. The easiest way to do this is to avoid eye contact, she said.

The underlined phrase size up in Paragraph 7 is closest in meaning to _______.

A. judge B. ignore

C. put up with D. make the best of
