Do you know your mobile phone number well? Your number has 11 digits(数字). You may sometimes find it hard to remember your number. That’s because China has the longest mobile phone numbers in the world. Why is that?

The 11 digits include three parts. Each part has a different meaning. The first three numbers tell you the mobile phone service provider you are using. For example, 135 is for the China Mobile Communication Corporation(中国移动)and 188 is for China Unicom(中国联通). The fourth to the seventh digits tell you where the number is from. And the last four digits are random (随机的).

The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits from 1999.

Eleven digits can make tens of billions of mobile phone numbers. That’s enough for each person to have seven or eight phone numbers to use in China. Also, we can use the mobile phone numbers again. Usually, the service provider will use a canceled number again after three to six months. If you call a number that you haven’t called for a long time, you may find its owner has changed.

Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot make as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada’s mobile phone numbers are perhaps the world’s shortest: they use seven digits.

1. What can we learn from the mobile phone number 188-4792-83437?
A.The service provider is the China Mobile Communication Corporation.
B.The digits 4792 tell you the area the mobile phone number is from.

3. What does the underlined word “canceled” mean in Chinese?

文章大意:本文是一篇议论文。文章主要介绍了时尚与医疗之间的一些实例,希望我们从中能多思考时尚如何更好的在医疗中发挥作用。

【推荐1】No doctor has ever considered that a shirt can save a patient’s lie. But on a family summer vacation in 2017. Rob Leibowitz wore a T-shirt while walking around Disney World with the words: “In Need of Kidney, O Positive.” A few months after a picture was posted on Facebook, Leibowitz, who had been on the list for several year, had a successful surgery with a kidney donated (捐赠的肾脏) by a complete stranger. Although this story might be unusual, it made me wonder: can medicine and fashion intersect in other ways?

They might seem like as strange a combination as red and green. Yet fashion is already being considered in heath care settings. For example, the effect (影响) of hospital gowns on patients has been studied, and many patients report feeling a loss of privacy (隐私) when putting on a gown. The gown even drove patients to have the idea that they were unwell.

As a result, designers (设计师) have rethought what a patient gown could look like. Such redesigns have not been widely accepted by hospitals yet, perhaps because the gowns have to be cheap, easy to make and easily washable. However, gowns in different sizes and colors might help give the patients a feeling of control and support—especially when so much is out of their control.

In fact, creative solutions to patient gowns have already been shown to have some positive effects. At Weill Cornell, young patients undergoing MRI scans (核磁共振检查) were given an “MRI-am-a-Hero” kit to make the experience feel like part of a superhero adventure. Researchers found that the number of kids who needed medicine to stay calm decreased (减少).

My own experience also has shown me the value of thinking about how important fashion can be in medical settings. A few years ago, I was working on a study about how patients could find kidney donors through social networks. I remember asking one woman about her pink shirt, with “Help Me Find a Kidney” on the front and a picture of her and her family printed on the back. “Every time I put it on,” she explained, “I am reminded that there is still hope.”

1. The underlined word “intersect” in Paragraph 1 probably means “________”.
A.get connectedB.become differentC.be comparedD.stay expensive
2. The writer probably agrees that ________.
A.making gowns easily washable is unimportant
B.redesigning gowns needs much money and new tools
C.gowns with creative designs can help patients get support
D.patients with terrible illnesses must post their needs online
3. What can be the best title for the article?
A.Dressing for HeathB.Fashion Will Never Leave
C.Ideas with ImaginationD.Patients Ate Always Waiting

【推荐2】In the 2lst century people often join a“group chat”on Wechat, share videos on Douyin and give opinions on Facebook. We live in a world that has accepted the social media(媒体)wholeheartedly. Being the international common language, English has lent itself willingly to be used on social media, experiencing many small but important changes during the process.What are the effects of the social media on the English language?

Old words but new meanings

When someone wants to post something on his“wall”, why do we think of the homepage of his Facebook, and not the walls in his house? This is the magic of social media. We know“friend”is a noun, but now it's also used as a verb. “friended”and“unfriended”mean the process of adding or deleting someone from your list of friends.

♦__________________________

Social media has invented new words like“selfie”or“emoji”to describe the new things. The most famous of these words perhaps is “google”which is used more than the old-fashioned simple word“search”.Generally speaking, a new word should be in use for at least 10 years before being entered in the Oxford English Dictionary. However, the dictionary officially included the word“tweet”.

♦Introducing acronyms(缩略词)

LOL (Laugh Out Loud). OMG (Oh My God) and BRB(Be Right Back)are examples of acronyms, the same as IDK(I Don’t Know)and TTYL(Talk To You Later). We need them to be short in length on social media, so we use acronyms to take the place of these phrases.

Social media is without doubt here to stay. In the future, it's likely to develop to a greater degree and take the English language along with it on the road of development.

1. What does the first paragraph mainly tell us?
A.Social media can be easily found in our daily life
B.It's exciting for everyone to live in the 21st century
C.Social media has a big influence on the English language
D.It's necessary for teenagers to make full use of social media
2. Which of the following can be put in_________________?
A.Creating short phrasesB.Introducing new words
C.Showing simple expressionsD.Keeping old but necessary words
3. What can we infer from the passage?
A.TBH can be the acronym of To Be Honest.
B.English is becoming more and more important.
C.It's a long way for social media to become perfect
D.Wechat, Douyin and Facebook are popular in China

文章大意:本文主要介绍了芯片短缺带来的影响。

【推荐3】Carmakers around the world are being forced (被迫的) to make fewer cars because they can’t get enough computer parts. As a result, several factories have had to close down for a while.

When you think of car parts, you might not think of computers. But a small unit of a computer, called the microprocessor (微处理器), is very important in modern cars. And these microprocessors, often called chips (芯片), are used to control many different parts of a car. A modern car may have as many as 150 chips.

Last year, with the world locked down because of COVID-19, many carmakers had to close their factories. Since they didn’t make cars, they canceled many of their orders with chip makers, which forced the chip makers to stop making so many chips for cars. They started looking for other customers, and soon began selling lots of chips to other kinds of companies. Now those carmakers are ready to start making lots of cars again, but there aren’t enough chips. Another reason for the chip shortage (短缺) is that there aren’t many companies making them.

How bad is it? The chip shortage has already caused carmakers to produce 500,000 fewer cars, according to a company that studies the car business. The company expects that number to drop by 300,000 more cars this year.

In the US, President Joe Biden asked the government for $37 billion to help make sure that more chips would be made in the future. Evens, it’s unlikely to solve the problems the carmakers face now in a short time. Most people expect the chip shortage will last for months.

1. What’s the problem with the carmakers right now?
A.They can’t sell their cars.
B.They’re forced to make computer parts.
C.They don’t have enough money.
D.They don’t have enough chips to make cars.
2. How many cars may be cut off this year according to the passage?
A.200,000.B.300,000.C.500,00.D.800,000.
3. What can we learn from the last paragraph?
A.The problem will be solved in a month.
B.The US takes this problem very seriously.
C.Chinese factories have enough chips to keep making cars.
D.The US government will provide $37 billion for carmakers.
