Scientists have found that the cause of this strange weather is that the air circulation pattern has changed and is now more variable than earlier in the twentieth century. This means that different regions of the world get long spells (持续时间) of the same type of weather, whether hot , cold, wet or windy.
However, weather experts have different views about why this has happened. One theory is that the temperature of the sea has increased. Another is that man’s activities on earth have disturbed the balance of nature.
Whatever the cause, the economics of many countries in the world depend upon the weather. And until we know exactly what effect man’s activities are having on the weather, we cannot make changes which might help. So for the moment the only answer is …wait and see!

The summer holidays are the best part of the year for most children.The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields.Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside.Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something which they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpool or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside？ I think it is the sand, sea and sun more than any other things.Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that makes the seaside what it is.
1.Summer holidays start _________.
A.with July

D.in August
2.After the examination, all pupils leave for home ________.

D.meet their old friends
5.Children like the seaside so much because they can _______.

C.take a sun bath
D.do all of the above
ort, and convenience. These cars will float along never touching the ground, and therefore will have no need for wheels. Annoying highway vibrations, caused by the rotations of the disc-and-tire wheels, will be things of the past. The coming highway passenger cars will literally fly above the road, supported on columns of air compressed by
turbine-driven fans.
The car without wheels has been called a “flying car” , and, in a sense, that’ s just what it is; however, it will not back out of the family garage, start down the street, and then suddenly go quickly upward heading for some distant point. On the contrary, to avoid problems in aerial navigation, the wheel-less vehicle probably will travel no more than three inches above road surface. It will travel over fairly rough road and even over smooth water.
The inevitable problems of maritime regulations, severe weather conditions, and running out of fuel in remote areas all will require new concepts of operation, servicing, and vehicle regulation.
