【推荐2】Recently, a company has come up with software that can grade our papers for teachers. With this new software, students submitting their papers online can get immediate feedback(反 馈)： no more waiting until the professor gets around to grading their work, probably leaving inky fingerprints on the pages.

Having a program grade papers would obviously free teachers to do other things, but I think it would be a mistake. As a teacher, I may begin to understand students by their conversation or how they respond in class, but when they actually have to put their thoughts on paper， I can learn a huge amount in a short time. I can see how they think and feel in relation to the material before them, and if they have problems in making connections, organizing arguments, and drawing conclusions.

The truth is, students rarely come to college knowing how to write well. This takes a lot of what one of my old professors used to call "correction''. I remember sitting beside him in his office as he went over my papers. He would draw a red pencil through adjectives, suggesting that I find stronger nouns. Don't say it was a "long narrow street. Call it an alley(小巷)if it's an alley. I learned from him how to make sentences more powerful and how to make arguments more persuasive.

Really education lives in sitting side by side with a student, in face-to-face exchange of ideas and feelings. Grading papers often represents the beginning of a good exchange.

I think my best teaching moments have occurred off-stage, late at night. I would spot a problem in a student paper and respond at length, in writing, in the margins(页边空白). This would lead to a meeting in my office, where the student would come back at me to discuss what I'd written. The conversation would continue for a very long time.

I don't think any software program is ever going to replace people in education. It may offer some help, but it's not the real thing.

【推荐3】China successfully sent the 52nd and 53rd satellites of its domestically developed BeiDou Navigation Satellite System （BDS）-the last two medium Earth orbit （MEO） satellites for the BDS-3 constellation（星座）－into space on Monday, marking the completion of the global navigation system's core constellation deployment（部署）and this year's BDS satellite launch campaign.

Launched from Xichang Satellite Launch Center, Sichuan Province, on board a Long March-3B carrier rocket with an Expedition-1 upper stage, the two satellites were injected into planned orbits after more than three hours' flight.

Since the first BDS-3 satellite was launched on November 5, 2017, China has conducted 18 BDS satellite launch missions, successfully sending 30 into their planned orbit, setting a national record for highest mission frequency and success rate.

In-orbit tests will be carried out before the two MEO satellites are commissioned（正式委托）.By then the core constellation for the Chinese global navigation satellite system will be successfully completed.

Wang Ping, chief designer of the BDS-3 system, said that the hybrid constellation design, in which three groups of satellites-the Inclined Geo Synchronous Orbit （IGSO）, MEO and geosynchronous Earth orbit （GEO）-work in concert in different orbits, was an exclusive BDS innovation and a world first. “Existing global navigation satellite systems, such as the US GPS and Russia's GLONASS, only have a MEO satellite constellation, ” said Wang.

The MEO satellites, in orbit 20, 000 kilometers above Earth, are a special type of satellite providing global service, while the IGSO and GEO satellites, in an orbit 360, 000 kilometers above Earth, mainly enhance regional service quality, according to Wang. That explained why completion of the MEO constellation was significant, marking the completion of the core network for BDS-3, meaning a stable BDS-3 global coverage without weak points has been carried out.

Feedback shows that the BDS service quality was already comparable to GPS since the end of 2018, and after completing BDS-3, “We will be as good as any GNSS, ” Wang said.

1. How many BDS satellites were sent into their planned·orbit successfully?

A．3.

B．5.

C．18.

D．30.

2. What's the advantage of BDS compared with GPS and GLONASS?

A．The excellent service quality.

B．The diverse functions.

C．The lower cost of designing it.

D．The ability to work in different orbits.

3. Why are the MEO satellites important?

A．They can serve the world.

B．They can enter farther orbits.

C．They can avoid all the weak points.

D．They can be put into use immediately.

4. What may be the best title for the text?

A．Exploring Space Is Very Important to the World

B．The BDS-3 System Has Benefited Many Countries

C．The Core Constellation of BDS-3 Completes Deployment

D．China Becomes the First Country to Launch a MEO Satellite

【推荐1】What will man be like in 5,000 or even 50,000 year from now on? We can only make a guess, of course. However, we can be sure that he will greatly differ from what he is today.    1    

Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today.    2     Five hundred years is a relatively short period of time, so we can imagine that man will continue to grow taller. Nowadays our eyes are in constant use. In fact, we use them so much that often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.

On the other hand, we make less use of out* arms and legs.    3     We can’t walk farther. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. What about our brain? As time goes on, we shall have to use our brains more and more and eventually we shall need larger ones!    4     Our head, in particular the forehead, will larger.

Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may be true.    5     He will still be a human being with thoughts and emotions similar to our own.

A．For man is slowly changing all the time.

B．As a result, these are likely to grow weaker.

C．Man will live in the earth for a long time.

D．Now on average, man is about three inches taller.

E．This is likely to bring about a physical change, too.

F．What9s more, man is likely to have a wonderful life.

G．All in all, in spite of all these changes, future men will still have a lot in common with us.

【推荐2】Space tourism is the term used to describe space travel for recreational or leisure purposes. What was once only a dream, as described in A Space Odyssey by Arthur C. Clarke, is now becoming a reality.

Futurologists attempt to make predictions of what life will be like in the future. After the first man landed on the moon, they thought that hotels would be built on the moon by the year 2000. They also considered the possibility that, in the 21st century, families might go for a holiday on the moon. Neither of these predictions have come true yet-but the rapid development of technology may mean these predictions are possible in the years to come.

Space Adventures is currently the only company to have succeeded in sending paying passengers into space. It worked with the Federal Space Agency of Russia and Rocket and Space Corporation Energia to provide flights for the world’s first private space explorers. Each paid over $20 million for their 10-day trip to the International Space Station.

Following successful explorations into space, other companies are now considering the possibility of enabling tourists to visit space. To make it affordable, suborbital space travel is being considered by some companies, like Virgin Galactic. Passengers would be transported to a height of between 100 and 160 km above earth, experience 3 — 6 minutes of weightlessness and a view of the stars before back to earth. This is expected to cost around $200, 000 per person.

Whilst it could be an enriching experience, there are some disadvantages. Many critics say that a huge growth in the spaceflight industry could drastically speed up the process of global warming. The ozone layer would be damaged further and the polar regions would suffer. In addition, space travel is only really affordable for the super-rich, though Virgin Galactic claims to be ‘opening space to the rest of us’.

A．The future life on the moon.	B．Landing on the moon in 1969.
C．Predictions about trips to the moon.	D．The history of the moon exploration.

3. Why is suborbital space travel considered possible?

A．It’s cheaper.

B．It’s safer.

C．It’s greener.

D．It’s convenient.

4. What is some critics’ major concern about space tourism?
