【題目】

On April 2, we said goodbye to Tiangong I, China’s first space lab. According to the China Manned Space Agency (中國載人航天), Tiangong I re-entered the Earth’s atmosphere (大氣層) and some of its debris (碎片) fell into the South Pacific Ocean.

There are many spacecraft (宇宙飛船) that are still in orbit

(軌道) above the Earth. After finishing their trips, they will all re-enter the Earth’s atmosphere like Tiangong I.

There are two types of re-entries: controlled re-entry and uncontrolled re-entry.

Some satellites and manned spacecraft come back to the Earth in a controlled re-entry. Experts calculate (計算) the path of the falling spacecraft and its speed. Thy can guide the spacecraft to fall in a chosen area.

Some spacecraft may have problems while in space after a certain amount of time. These spacecraft come back in an uncontrolled re-entry. It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was hurt.

During re-entry, most of the spacecraft will burn up while passing through the Earth’s atmosphere. Only a small amount of the debris will reach the ground. The debris typically ends up falling into the ocean, China Daily reported.

【題目】A group of students from the US have been in China for a week. Here is part of their chat history (聊天記錄) on WeChat.

20:45

Hi, everybody! Anything to share today?

20:49

Yes. I went to a restaurant to have dinner with some friends this evening.

When we finished the meal, the waiter brought us the bill. It was 270 yuan.

We gave him 300 yuan and left 30 as a tip(小費) for his service(職務(wù)).

To our surprise, he returned us the change!

Really? How kind he is!

20:53

@Sunny It’s different form that of the US. I worked in a restaurant in my free time. I accepted tips. Well, something interesting happened to me this morning…

20:55

I couldn’t find the bus stop. I came up to a man who was walking near me and showed him the bus number. He nodded and asked me to follow. We walked for about 10 minutes and finally got to the bus stop. I wanted to give him a hug (擁抱) to show thanks, but he just said goodbye and walked away. I couldn’t believe that he had taken so much trouble for a stranger(陌生人)!
