Have you ever noticed that your fingertips are winked when you’ve just finished swimming or washing dishes? It seems as if your hands have aged 30 years in a second. But is this an accident? Or is it something that nature has built into our bodies?
If your finger’s wrinkling up had no use at all, “ it wouldn’t need to.” Professor Tom Smulders from Newcastle University, UK, told BBC News. By studying wet fingers closely, Smulders and his partners found that the wrinkles looked a bit like the patterns on the car tire or on the bottom of the running shoes. So they made a guess that wrinkles on fingers might be able to help the hand hold things more tightly.
To test this, researchers asked 20 people to pick up marbles from water with their hands. But before they started, some of the people had to keep their hands in water for half an hour.
The researchers found that the people with wrinkled fingers completed the task the task faster than those with dry hands. But when they were asked to move dry marbles, all the people performed equally well, no matter they had the wrinkled fingers or not.
Our ancestors might not have played with marbles, but wrinkled fingers could have made it easier for them to climb around in the wet forests and catch fish from rivers, researchers say.
Similarly, our toes also get wrinkled in water. This may have developed from our ancestor’s need to run on wet ground.
But the question is, if wrinkled fingers are so helpful, why don’t our hands just stay that way all the time? Researchers explained that wrinkling has its disadvantage: wet fingertips are far less sensitive than smooth ones, reducing our sense of touch.
1.What does the underlined world “this ” in the third paragraph refer to?
A. Whether fingers have wrinkles after they are put in water.
B. Whether wrinkled fingers can hold things more tightly.
C. Why keeping things in water makes them wrinkled.
D. Why wrinkles help hands hold things more tightly.
2.The test shows that ________.
A. winkled hands hold dry things more tightly than dry hands do.
B. dry hands hold dry things more tightly than wrinkled hands do.
C. winkled hands hold wet things more tightly than dry hands do.
D. dry hands hold wet things more tightly than wrinkled hands do.
3.What might be the disadvantage of wrinkled fingers?
A. They are too sensitive to be touched.
B. They might be more likely to get hurt.
C. They cannot hold things tightly enough.
D. They are not so sensitive as dry fingers.

When throwing away rubbish, do you know which bin it should go in? Have you ever noticed the differently-colored rubbish bins on the street? Some of you might not be able to answer the questions. However, it's actually quite important to know how to sort your rubbish. Not knowing how to sort rubbish can make it harder to save energy and protect the environment. If you don't sort your rubbish, all of it will be buried (埋) together. It can take up large areas of ground that could have been used for planting trees. Shanghai is the first city to put rubbish-sorting into practice in China.
Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable (可回收的), harmful and dry. "Wet" rubbish is also known as "household" rubbish. It is what people produce every day after they eat or drink. "It is the thing you don't want but pigs can eat", Guangzhou Daily explained. Paper, metal, glass and other things that can be reused are recyclable rubbish.
Harmful rubbish includes things like medicine, batteries and so on. Finally, any rubbish that is not wet, recyclable or harmful will go in the dry rubbish bin. Many other Chinese cities, including Changsha, plan to use this method to sort their rubbish. Now that you know this, perhaps you can do your part in protecting the environment.

When throwing away rubbish, do you know which dustbin it should go in? Have you ever noticed the differently-colored dustbins on the street?
Some of you might not be able to answer this question. However, it's actually quite important to know how to sort(分类)your waste. Not knowing how to sort waste can make it harder to save energy and protect the environment.
If you don't sort your rubbish, all of it will go to a landfill(垃圾清理场)and be buried together. These landfills can take up large areas of ground that could have been used for planting trees or crops. The electronic waste you throw away, such as batteries, can pollute the soil and groundwater. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.
With this in mind, many cities in China have been running waste-sorting campaigns(活动)in recent years. for example, Shanghai announced in 2018 that within three years(2018—2020), all the people living in Shanghai should sort their rubbish into four groups: wet, recyclable, harmful and dry.
Wet waste is also known as household waste. They are things you don't want but that pigs can eat. Paper, metal, glass and other things that can be reused are recyclable waste.
Many other Chinese cities, including Shenzhen, are using this method to sort their rubbish. Now that you know this, perhaps you can do your part to protect the environment and encourage others to sort their rubbish.
根据短文内容,判断下列句子正(T)、误(F)。
1.If you know how to sort waste, it will help us save energy and protect the environment.
2.Shanghai will achieve the goal of sorting their rubbish into four groups in 2020.
3.The food that we haven't finished eating at home belongs to recyclable waste.
4.Many cities in China are doing waste-sorting work nowadays.
5.The passage mainly tells us how to recycle rubbish.

You might have noticed that sometimes, when you are playing mobile games, the picture suddenly freezes(卡顿)because the network speed is o slow. However, these annoying things will soon become a thing of the past, as China just issued commercial licenses (发放商用牌照)for 5G networks on June 6, 2019. This means that China's telecommunications companies will be able to offer 5G network speeds to users.
The "G" in "5G"stands for generation. IG let us talk to each other, 2G let us send messages, 3G gave us mobile data and internet, and 4G made all of these things faster. So what will SG bring?
It will allow us to download an entire HD movie in seconds. The delay(延时)between sending and receiving data will be shortened. Now, 4Gtakes about 100 to 200 milliseconds, while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to I millisecond or less, which is almost real—time.
With the development of 5G, new kinds of technology will be created and used.
Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay. Self—driving cars will be able to drive more safely because they can smoothly communicate with each other, traffic lights and road sensors.
5G networks will be powerful, but not perfect. They do have some disadvantages.
On one hand, 5G signals don't go very far. On 4G networks, you can be 10 kilometers away from the nearest transmission base(传送基站)and don't lose signal. But 5G maxes out at about 300 meters. On the other hand, 5G signals have a hard time going through walls and rains. This means we will need to build many small transmitters to make sure 5G signals can be received everywhere. Soon you may see small boxes on every street lamp and building.
1.Why does the picture freeze when we are playing mobile games?
2.What does "G" in"5G"stand for?
3.How long will it take to download an entire HD movie with 5G?
4.What is the fourth paragraph mainly about?
5.What disadvantages do 5G networks have?

You might have noticed that sometimes, when you’re playing mobile games or making a video call, the picture suddenly freezes(卡顿)because the network speed is too slow. When you try to download a movie on your phone, it seems to take forever.
These annoying things will soon become things of the past, as China just issued commercial licenses(发放商业牌照)for 5G networks on June 6. This means that China’s telecommunications(电信) companies will be able to offer 5G network speeds for mobile phone users.
The “G” stands for generation (代) . 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and Internet, and 4G made all of these things faster. So what will 5G bring?
First of all, 5G is so fast that it will allow us to download an entire HD movie in a second. The delay(延时) between sending and receiving data will be shortened. Now, 4G takes about 100 to 200 milliseconds(毫秒),while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to 1 millisecond or less, which is almost real-time.
Because of this increase in speed, it will be possible to create and use new kinds of technology. Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay. Self-driving cars will be able to drive more safely because they can smoothly communicate with other cars, traffic lights and road Sensors (传感器). 5G also makes the Internet of Things(IOT物联网)possible.
All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.
1.From the first paragraph we can know that________.
A.people can’t download movie at all on the phone
B.making a video call is impossible for phone users
