【题目】

Your Internet experience must be uncomfortable when the net speed is too slow — it takes so long to open a web page and the reality shows you’re watching stops every few minutes. That can make you angry.

But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China’s major telecom carriers (电信公司) would start to provide 5G services.

1. What is 5G?

The “G” in “5G” refers to “Generation”. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster. The mobile network technologies are developing quickly.

Now 5G promises much faster data download and upload speeds, and more stable (稳定的) connections. This means that you will be able to download a complete HD movie in seconds and only experience a short delay (延迟) between sending and receiving data.

2.What changes will 5G bring us?

With a 5G network, the short delay in information exchange will allow driverless cars to run more safely. Meanwhile, 5G-enabled wearable devices (设备) will be in use in hospitals. Besides,VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

3. Does 5G have any disadvantages?

According to the BBC, though 5G will make our lives more convenient, it will not be perfect. For one thing, 1 . On 4G networks, you can be 10 kilometers away from the nearest transmission base and hardly lose signal (信号). But 5G will only cover about 300 meters. And in order to use 5G, we will have to buy new products designed for 5G that are expensive at present.

【1】“G” in “5G” means the generation of________.

A.the mobile network experienceB.the mobile communication technology

C.the speed of data download and uploadD.the delay in data exchange

【2】According to the passage, the best sentence for the blank is 1 .

A.5G will not “travel” farB.5G will be used in a limited way

C.products designed for 5G is expensiveD.5G has its both advantages and disadvantages

【3】What is the passage mainly about?

A.Changes in the mobile technologies.B.The uses of 5G.

C.Disadvantages of 5G.D.An introduction to 5G.

【答案】

【1】B

【2】A

【3】D

【解析】

本文是一篇说明文，主要讲述了什么是5G，5G带给我们的改变和5G的缺点。

【1】

细节理解题。根据第3大段“The “G” in “5G” refers to “Generation”…The mobile network technologies are developing quickly”5G里的G是指“一代”，移动网络技术发展迅速。可知，5G里的G也是指移动网络交流技术。故选B。

【2】

推理判断题。根据第6大段“On 4G networks, you can be 10 kilometers away from the nearest transmission base and hardly lose signal (信号). But 5G will only cover about 300 meters.”4G网络里，你可以在距离最近的传输基地10公里的地方，几乎不会失去信号，但是5G只能覆盖大概300米。可知，空格句子的意思指5G走不远的缺点。故选A。

【3】

最佳标题题。根据小标题“1. What is 5G? 2.What changes will 5G bring us? 3. Does 5G have any disadvantages?”5G是什么，5G带给我们的改变和5G的缺点。可知，本文在总的介绍5G。故选D。

	Ping Pong Door Do you want a ping-pong table in your room? But you may not have enough space. Now this door is here to help you. It can turn into a ping-pong table when you pull it down. After the ping-pong game is over, it goes back to being a common door. It was designed by Tobias Frnzel from Germany. Cool idea!
	Dog Watch The dog watch is a “clock for keeping time at a rate(比率) other than human time” and was invented in 1991. With this watch, you can know time at your animal’s rate instead of your own. The watch multiplies（乘）every human time by seven, giving us “doggy time”. If a dog lives to be the age of 14, that translates into 98 human years!
	Earthquake House Big earthquakes can hit a house, possibly making the people in it get hurt. But Dysinger has found a way, the Earthquake House! His idea is simple. Build a round house that has earthquake sensors(传感器) in it. If the sensors know the big earthquake, the house is free from its chains(链条). Don’t worry. You always remain straight in it.
	Smell This How do you know if your breath smells nice, or if it smells bad? It’s difficult to know because it’s very hard to smell the air that comes out of your own mouth. Smell This is useful for this situation. You just place the mask on your face, then breathe out through your mouth and breathe in through your nose.

【题目】

Have you stroked (抚摸) a cute dog recently? If that dog touched you with its nose, you might find how wet and cold it was. If dogs are so warm and fluffy (毛茸茸的), then why are their noses so cold?

Before, people thought that dogs had cold noses to help them control their body temperature. But, a new study in the journal Scientific Reports has shown some interesting findings about dogs’ noses. The study found that when the air temperature was 30 ℃, the tip of a dog’s nose is about five degrees cooler than the air. But why is this?

The researchers believed that the tip of a dog’s nose has a special sensory function (探测功能). So, they did an experiment to test it. The study showed that dogs could find weak heat sources—like a small animal—with their noses from 1.5 meters away.

The research team studied three dogs named Charlie, Delfi and Kevin. For the experiment, the dogs had to tell the difference between two objects. The two objects were heated to different temperatures. Amazingly, all three dogs were able to sense the temperature difference between both objects.

The study also found that the heat from the objects in the experiment “was too weak to be felt by human hands, even at very short distances”. The dogs were able to sense these heated objects from a distance, but humans were only able to feel the warmth of the object if they touched it.

To know more about it, the research team also studied the brain activity of 13 dogs. When a warm object was put near their noses, there was an increase in brain activity.

“From the two complementary (互补的) experiments, we can know that dogs are indeed able to sense heat from warm-blooded animals, and a special region of the brain is made to be active by such heat.” said Anna Balint, the leader of the study.

【1】What did the new study published in the journal Scientific Reports find about dogs?

A.What makes dogs loyal.B.Why dogs have cold noses.

C.How dogs feel heat better.D.How a dog’s temperature influences its brain activity.

【2】Which of the following words has the closest meaning to “region”?

A.Way.B.Area.C.Type.D.Change.

【3】What happened to the dogs when a warm object was put near their noses?

A.They showed no change in their brain activity.B.They had different kinds of excitement.

C.Their brain activity slowed down.D.Their brains became more active.

【4】What can we infer from the passage?

A.Heat sensing ability can help dogs hunt for food.

B.The tip of a dog’s nose has a special sensory function.

C.Dogs are smarter than other animals.

D.The two experiments found different results.
