Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.
There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸气).
Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.
Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.
【小题1】Where can we find water?

If you enjoyed the spring-like sunshine over the weekend and thought the weather has finally turned a corner, you’re sadly mistaken.
Chilly (寒冷的) days and grey clouds are forecast for the week—making it far too early to pack away the winter woollies.
Temperatures will struggle to rise above zero at night and fail to make double figures during the day.
People enjoy the spring sunshine in Sefton Park, Aigburth, Liverpool. Forecasters have predicted a return to chilly weather this week.
Met Office forecaster Charlie said, “It was a nice, dry, bright weekend in many parts and Monday is going to be a similar affair for many.”
“Temperatures will be between 5℃and 8℃, which is below average for the start of spring.”
The sun will disappear from the south of the country after today, with dry but cloudy conditions forecast for tomorrow and Wednesday. 
Wednesday will be warmest of the three, with temperatures peaking at 9℃. But this is still two degrees below the March average for the district.
Overnight, temperatures will drop sharply, with lows of minus 3℃for the next three nights.
“It will generally stay on the cold side of average,” said Mr. Powell.
The March misery comes at the end of the coldest winter for more than 30 years.
Temperatures in December, January and February struggled to stay above zero, with the UK’s average 1.5℃, making it the deepest freeze since 1978—79.
It claimed there was just a one-in-seven chance of a cold December to February.
The agency also sadly predicted a “barbecue summer”, saying it was “quite optimistic” that it would be warmer and drier than average.
Following the two mistakes, the Met Office has dropped its long-range seasonal forecasts and will instead publish a monthly prediction for Britain, updated once a week.
In its defense, it says that while short-term forecasts are extremely accurate, Britain’s size and geographical position makes long-term predictions much more challenging.
It also points out that it gave warning of any heavy falls of snow this winter.
60. According to the passage, the weather on Tuesday in the south might be _______.
A. dry but cloudy  B. sunny but chilly  C. sunny and warm  D. cloudy and chilly

B. The Met Office has shortened its forecast range.
C. The weather forecast becomes more and more accurate.
D. The agency was quite confident of long-term predictions.
62. Which of the following would be the best title for the passage?
A. The big chill isn’t over yet                     B. A warm spring finally arrives
C. A heavy snow is on the way                 D. The Met Office drops forecasts
63. From the passage, we can conclude ________.
A. the weather report is more and more important
B. British people become worried about bad weather
C. Britain has just experienced a very freezing winter
D. The Met Office can always predict any heavy snow falls accurately

Seeing from the foot of the mountain, clouds are seen beautifully ____over its top.

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．

Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．

We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．

Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．

1.Which of the following is NOT done by satellites according to the passage?

2.What’s the speed the earth rotates at?

3.Why does the satellite move around the world at the same speed as the Earth rotates?

4.What does the underlined word “This” in the 3^rd paragraph refer to?

5.Which is true of satellites?
