Books are in Latin.Some Romans（羅馬人） went to other parts of the world. They took their language with them. Soon Latin was used in many countries. It became a world language.People in other countries did not talk in Latin the same way. In each land, they changed the language a little. As time went by, they made more changes.

Many people e to watch football and they want their team to win. Which of the following is not their act?A. Jumping B. throw B. how to play footballC. American sport s D. seven days or even longer5. The main（主要的）idea of this passage is that satellites are now used in _________.A. taking pictures of the atmosphere B. receiving pictures of the atmosphereC. doing other work in many ways D. weather forecasting【013】In almost every big university（大學(xué)）in the United States, football is a favourite sport. American football is different. Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the other end of the field. They have four chances（機會）to move the ball ten yards（碼）. They can carry it or they can throw it. If they move the ball ten yards, they can try to move it another ten yards. If they move it to the end of the field, they receive six points（點.It is difficult to move the ball. Eleven men on the other team try to stop the man with the ball. If he does not move the ball ten yards, his team kicks the ball the other team.Each university wants its own team to win. Many thousands of people e to watch. They all shout for their favourite team.Young men and women e on the field to help the people shout more. They dance and jump while they shout.Each team plays ten or eleven games each season.The season begins in September and ends in November.

Many people go to see these games and many others watch them on TV.1. The passage talks about ___________.A. football D. above space2. Why do we use the weather satellites to take pictures of the atmosphere? Because __________.A. the weather satellites can do it easily B. clouds form thereC. the weather forms there D. the pictures can forecast the weather3. Meteorologists forecast the weather __________.A. when they have received satellite picturesB. after they have pared new satellite pictures with earlier onesC. before they received satellite picturesD. during they study satellite pictures4. Maybe we’ll soon be able to forecast the weather for ________.A. one day B. in the atmosphere C. above the ground D. Can Bees See Color?【012】Now satellites are helping to forecast（預(yù)報）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大氣）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（氣象學(xué)家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists pare（比較）them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.1. Satellites travel _______
