Everyone {#blank#}1{#/blank#} (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 {#blank#}2{#/blank#} (provide) with moving roads. One side of the road travels {#blank#}3{#/blank#} one direction; the other side moves {#blank#}4{#/blank#} opposite way. Anyone who wants to go to another part of the city steps on the moving “way” and sits on one of the seats until he arrives. He has none of the troubles {#blank#}5{#/blank#} a private car brings with it: whether there is enough petrol, whether the tyres are all right, where to park it. The moving way is always at his service, always moving {#blank#}6{#/blank#} (silent) along, always ready {#blank#}7{#/blank#} (take) him to his destination. That city of the future has no traffic jams.

    To link up the {#blank#}8{#/blank#} (vary) cities, vehicles driven by atomic power will pass along highways {#blank#}9{#/blank#} (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 {#blank#}10{#/blank#} (city), ports and other built-up areas, they will pass through underground tunnels.

    A few people have lucid (清醒的) dreams, in {#blank#}1{#/blank#} the dreamer is aware they're dreaming and can control the experience. Some others can learn {#blank#}2{#/blank#} (have) lucid dreams. The practice can be used to deal with frightening dreams. However, its potential has been limited by it often {#blank#}3{#/blank#} (be) so hard to achieve. Now, researchers have developed the most effective method yet for promoting lucid dreams.

    The researchers let 121 adults aged 19 to 75 pick something {#blank#}4{#/blank#} (see)in a previous dream. It was called a "dreamsign" that can serve {#blank#}5{#/blank#} a reminder to become lucid when met again. The {#blank#}6{#/blank#} (volunteer) were then handed capsules. Each person got a high-dose (大剂量的) capsule, a low-dose capsule and a placebo (无效对照剂) capsule, but they couldn't tell which was which. On three occasions, they woke in {#blank#}7{#/blank#} middle of the night, took a capsule, imagined their dreamsign and went back to sleep. The high dose was most effective, causing lucid dreams in 42 per cent of participants. About 27 per cent {#blank#}8{#/blank#} (report) lucid dreams with the low dose and 14 per cent after taking the placebo capsule.

    The potential applications are {#blank#}9{#/blank#} (excite). "This new method has the success rate we need to be able to {#blank#}10{#/blank#} (proper) do research on lucid dreaming," says Denholm Aspy at the University of Adelaide in Australia.

    One night, {#blank#}1{#/blank#} winter, a bear came into the city in Vancouver Canada. It walked through the city streets past houses, shops and offices. Then it {#blank#}2{#/blank#} (find) some food in bins outside a restaurant and started eating. In the morning, someone saw the bear and called the police. The police came with a vet (兽医) from the city zoo. They put the bear in a lorry and took it to the mountains outside the city. {#blank#}3{#/blank#} (lucky), the bear was safe. But {#blank#}4{#/blank#} happens in other countries when big animals come into cities? In Vancouver it is unusual {#blank#}5{#/blank#} (see) a bear, but in some cities you can see big animals on the city streets every day.

    Big animals usually come into cities to find food. In Cape Town in South Africa baboons (狒狒) come into the city when they are {#blank#}6{#/blank#} (hunger). Human food is very bad for the baboons {#blank#}7{#/blank#} (tooth) because it has a lot of sugar. Now, there are Baboon Monitors working in Cape Town. {#blank#}8{#/blank#} (they) job is to find baboons in the city and return them to the countryside.

    In Berlin in Germany, pigs sometimes come into the city for food. They eat flowers and plants in parks and gardens. Sometimes they eat vegetables from gardens {#blank#}9{#/blank#} they walk in the street, causing accidents. Some people like the pigs and they give them food and water to drink. Other people do not like the pigs and they want the government and the police to stop them {#blank#}10{#/blank#} (enter) the city.
