Everyone     1     (complain) about being stuck in traffic. It is quite possible that the future city will have no traffic at all. H.G Wells, in his book The Sleeper Awakes, tells something about the traffic. In the streets of that future London there will be no vehicles. The city     2     (provide) with moving roads. One side of the road travels     3     one direction; the other side moves the opposite way. Anyone who wants to go to another part of the city steps on     4     moving “way” and sits on one of the seats until he arrives. He has none of the troubles,     5     a private car brings with it: whether there is enough petrol, whether the tires are all right, where to park it. The moving way is always at his service, always moving     6     (silent) along, always ready     7     (take) him to his destination. That city of the future has no traffic jams.

To link up the     8     (vary) cities, vehicles driven by atomic power will pass along highways     9     (divide) into two main groups of lanes. Each group will consist of several lanes, some for slow traffic, some for fast. Crossroads will not exist on these highways, but will be replaced by bridges and junctions (交叉口). Where these highways enter     10     (city), ports and other built-up areas, they will pass through underground tunnels.

How will our continuously growing population affect our way of life, our environment, even our planet? No matter how you look at it, we will face     1     extremely serious problem. By the middle of the 21st century, we will have used up all the oil that     2     (drive)our cars if at the rate we’re going. Even if scientists develop some new     3     (way)of feeding the human race, the crowded conditions on the earth will make     4     necessary for us to look for open space somewhere else. But none of the planets in our solar system are able     5     (support)life at present. One possible solution     6     the problem, however, has recently been raised by an American scientist, Professor Carl Sagan. His idea is     7     before the earth’s resource are almost exhausted, it will be     8     (total)possible to change the atmosphere of Venus(金星) and so create a new world almost as large as earth itself.

However,     9     his idea is turned into reality, humans have a long way to go. On the one hand, Venus is much     10     (hot)than the earth; on the other hand, there is only a tiny amount of water there.

5G is developing, but most of us aren't really sure what it is or the reason     1     we need it. A big part of the reason is that 5G means more than one thing. If you ask different people, you     2    (provide) with different answers.

Experts believe that 4G is on     3     way out. In 2020, the U.K. is expected to use 5G. At present, it is unknown exactly what influence 5G will have on people's life but it is widely thought that 5G will     4     (definite) be faster than any generation of networks we have used previously.

Work will likely become much easier as 5G will allow quicker downloads and a better ability to work online even if there is no wi-fi connection. With the     5     (develop) of 5G, driverless cars will be able to communicate     6     other vehicles, which can reduce road accidents by about 10%, One of the most     7     (impress) things will be that people can see which seats on a train are accessible to     8     (they) when it arrives at the station.     9     (get) around the world will also be more convenient.

A number of     10     (company) are now working on bringing 5G to the market. It remains to be seen how much of the country 5G will cover and whether everyone will be able to benefit from it.
