根据短文，简要回答下面的问题，将答案写在答题纸的相应位置上。
In the early nineteenth century, people did not use stamps. They had to pay postage（邮费）when they received letters. Sometimes they didn't want to receive a letter at all, but they had to pay money for it. They were unhappy about this. The postage was high at that time, because the post offices had to send many people to get the postage.
Rowland Hill was a school teacher in England. He was the first to think of using stamps in the 1850s. He thought it would be much easier for people to use stamps. They could go to the post office to buy stamps and put them on envelopes（信封）before they sent the letters. The post office could just put seals（印记）on the stamps so that people could not use the stamps again. In this way, the post office did not need postman to get postage. It only needed fewer postmen to send letters.
小题1: Did people use stamps in the early nineteenth century?
___________________________________________.
小题2: What did the people have to do when they received letters?

阅读下面短文，根据短文内容完成表格中所缺信息，每空一词。
In common with many countries, Britain has serious environmental problems. In 1952, more than 4,000 people died in London because of the smog. The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot.
Today, London is much cleaner but there is a new problem: smog from cars. In December
1991, there was very little wind in London and pollution increased a lot. As a result, about 160
people died from pollution in just four days.
Part of the problem is the new ‘out of town’ shopping centres. In the past, people often walked to shops near their home or went by bus. Now, many people drive to the new shopping centres. As a result, the small shops have disappeared and more people have to travel to do their shopping.
Critics say that Britain needs better and cheaper public transport. Transport in Britain is very expensive. An early morning train trip from Glasgow to London (about 600km) can cost about
￡100, for example. A short 15-minute bus trip can cost over ￡1.00.
Many people are trying to reduce the use of cars in Britain. Some cities now have special bicycle paths and many people cycle to work. Some people also travel to work together in one car to reduce the pollution and the cost.
