The year 2019 marked the 40th anniversary of the start of diplomatic (外交) relations between China and the United States. When the Joint Communique on the Establishment of Diplomatic Relations《中美建交公报》went into effect on Jan 1, 1979, the two countries began a friendship that stays deep to this day. Whether it's stepped-up trade, shared entertainment markets (娱乐市场) or simply people-to-people exchanges, China and the US have helped each other grow and succeed.

Trade and economy (经济)

As the largest and second-largest economies in the world, the US and China have a strong economic relationship. They are both major trade partners for each other, exporting (出口) and importing (进口) billions of dollars worth of goods every year. As of October 2019, the total value of trade between both countries was nearly $468 billion (3.26 trillion yuan), according to US Census Bureau. Certain US products, such as high-end (高端) clothing and electronics brands (品牌), are in high demand (需求) in China. Likewise, China exports large amounts of manufactured (制造的) goods to the US, including clothing and industrial equipment (工业设备).


As the world's fastest-growing film market, China is Hollywood's top target (目标) at the moment, with new releases in China earning millions of dollars. Avengers: Endgame 《复仇者联盟4:终局之战》 for example, earned $614 million (4.28 billion yuan) in China last year, according to Box Office Mojo. China, for its own part, is working to develop its own movie industry and send its films abroad. The sci-fi film The Wandering Earth 《流浪地球》, which came out last year, did quite well in the US. It became China's third highest-grossing (票房最高的) film of all time with total worldwide earnings of nearly $700 million (4.88 billion yuan), according to Box Office Mojo.

People-to-people exchanges

The US is a top choice for many Chinese students who wish to study abroad. US universities have welcomed record numbers of Chinese students in recent years, with the total number of students reaching 360,000 as of June 2019, according to the BBC. This has allowed students from both countries to gain a greater understanding of each other's cultures. And, of course, there are those on both sides who choose to live and work in each other's countries. Many Chinese researchers work in US labs (实验室), while in China, there are many US citizens working in fields ranging (范围) from journalism (新闻) to English education.

I had hidden the long black bag in the garage for the past two days.Tonight,in the dark,I would finally take it away.If everything went OK,it would be done by morning.But I had to be sure no one,not even my wife,saw me.

It was more difficult to get away from the party than I expected.I said that the children were tired and needed to get to bed.It was partly true.But the main reason for leaving was that I wanted to complete my plan.

First I had to get the kids to sleep.That was never easy at any time and tonight it was even more difficult.The eldest one wanted to know why we left the party early.I told him 10:30 pm was not early.As usual,I read them a bedtime story,but I had to stop myself reading too quickly or they would learn my secret.

Silence finally came,and feeling like a thief in the night,I went out of the house and into the garage.Taking one end,I dragged the bag out from its hiding place and took it into the garden.I was worried that my neighbours might see me and call the police.

It was already eleven o’clock.By the light of the moon I started working,trying to make as little noise as possible.And that was not easy with a saw(锯子)and a hammer.

After much effort,my work was finally completed.I looked down at my watch.It was exactly 4:00 am.Then I went inside to have a shower and get a few hours of sleep.It wouldn’t be long now before the kids would rush into my room and wake me up to tell me about the new tree house Father Christmas had brought them this year.

Last year in the UK at least 45 people died and 900 more were injured in car accidents where drivers were using their mobile phones. Yet many people continue to use them while driving even though it's dangerous.

Research has shown that it is difficult to concentrate on driving and talking at the same time. It can even be more dangerous than driving after drinking too much. A recent study found that when drivers were talking on their mobile phones, their stopping times were 30 percent slower than when they had drunk too much—and nearly 50 percent slower than when they were driving normally. It also found that drivers talking on mobile phones were less able to control their cars than drunk drivers.

And talking isn't even the most serious problem, texting is. Unbelievably, another recent study reported that 22 % of adults admitted they had sent a text message while driving at least once in the past month. An average text message takes 90 seconds to write and send. That means for one and a half minutes a driver is looking at their phone's screen and not at the road. The arrival of new smart phones such as the iPhone will only make matters worse as they will allow users to do more things than ever before.

Using a mobile phone while driving puts others' lives at risk. No matter how well we drive, if another driver is not being professional or careful, we are put in danger by their actions. Such drivers are selfish, careless and should have their driving licences (驾照) cancelled.

There is no doubt that mobile phones call be fun and are extremely useful, especially when you're in trouble. But there is no need to use them while driving. Just wait until you stop or you will probably get into trouble of your own.
