【题目】 All networks like 3G and 4G will be things of the past, because 5G will be reachable in the near future. So, what’s so special about a 5G future? First, its download speed can be as fast as 20GB/s, which is 100 to 200 times that of 4G. But what’s more impressive is 5G’s low delay rate. Now 4G takes 200 milliseconds to send and receive information. But 5G will get it down to 1 millisecond.
5G is going to change the way equipment connects to the Internet. And self-driving cars may be one of the biggest breakthroughs to come out of 5G. The self-driving car under 5G network could react to hundreds of cars around it within 1 millisecond. It’ll prevent car accidents and end traffic jams completely.
5G can benefit us in other ways. Operations could be performed by robots controlled by experts from the other side of the world. Factories can be staffed by robots that can communicate their tasks to each other, and they can do more work over a 5G network. Imagine a group of drones(无人机) flying over a field of crops. Then farmers won’t have to work so hard anymore.
But, 5G is not perfect. One major shortcoming has to do with why it’s so fast. 5G uses the millimeter waves, while 4G uses the 15 to 40 centimeter-long waves. And shorter waves go fast but not very far. On 4G networks, the signal can go 10 kilometers. But the 5G signal can go at most 300 meters, and it can’t even go through walls or rain.
【1】How does the author show us 5G’s advantages in Paragraph I?
A.By giving examples of the uses of 5G.
B.By making comparisons between 4G and 5G.
C.By explaining the scientific principles of 5G.
D.By analyzing 5G’s development from 4G.
【2】According to the author, the self-driving cars will ___________.
A.cause more car accidents.
B.slow down 5G’s development.
C.run without being connected to the Internet.
D.have a much faster reaction speed than humans.
【3】What does the underlined part “ be staffed by robots” in paragraph 3 mean?
A.Be built by robots.
B.Have robots as workers.
C.Offer employees home robots.
D.Produce more medical robots.
【4】What does the last paragraph mainly talk about?
A.The main weakness of 5G networks.
B.How to make 4G networks more perfect.
C.The types of long waves and short waves.
D.How to improve the communication in rainy days.

A trail of hot springs dot the northern Kapong District. For tree worshipers, it's a site best described as awesome.

These original century-old shophouses are “so authentic” here a local told me, it can overwhelm Phuket people with nostalgia.
However, the town centre of Phang Nga is not Takua Pa, though. The story has it 【8】 back in 1809, the Siam-Burmese wars drove people down to Phang Nga bay，hence the new settlement that has now become the province's municipal seat. It's still small in size, but with newer natural charms. Mountains 【9】 (surround) Phang Nga with the most magnificent limestone peaks 【10】 create wonderfully amazing signature views. Driving through the town's small parallel streets and looking up, one can only marvel at Mother Nature. Perpetual rain and misty mornings to virtual greenness --- Phang Nga people will ensure you get all that.
