题型二 阅读理解
No one can know for sure what the weather is going to be like in the future, but many people think there are
going to be some differences.
According to (根据) the scientists, one difference is that in many places it’s going to be much hotter and it’s
going to rain less. Some countries in Africa are going to become very dry all year round, and people will hardly find
food and water. In Southern Europe and the United States, it’s going to be less easy for plants to grow. People there
are also going to have problems finding food in the future.No one knows how much warmer it is going to be, but scientists say that the change is going to be at least 2℃.
They say that the ice in the Arctic (北极) is going to melt in the next few years and a lot of the animals there are going
to die. There is also going to be more water in the sea, so cities near the sea are going to disappear (消失).
Another difference is that there are going to be more hurricanes and typhoons (飓风和台风). Scientists say
they are going to happen all over the world, and many people are going to lose their homes.
1．Scientists think it is ________ for people to find food and water in some countries in Africa.
A．unlucky B．difficult C．common D．easy
2．The underlined word “melt” in the third paragraph means ________.
A．become water B．become dirty C．turn white D．turn clean
3．We can know from the passage that ________.
A．the plants will be less difficult to grow in the USA
B．a lot of animals in the Arctic will still live happily there
C．few people will lose their homes because of more typhoons
D．people living in some cities near the sea will have to leave their homes
4．What’s the structure of this passage?
A． B． C． D．
Have you ever heard of an avalanche (雪崩)? The avalanche is a kind of sudden natural disaster like
earthquakes. During an avalanche, a lot of snow and ice rush down the mountain. As they rush, the snow and ice
move faster and faster. In fact, snow from an avalanche can move as fast as two hundred miles an hour. That is three
times faster than a car on a highway!
Most avalanches happen after big storms. In the mountains like the Alps and the Himalayas, there is snow and
ice all year round. After big storms, new snow puts more pressure (压力) on the snow that is already in the mountains.
It can make the old snow rush down.
Avalanches are very dangerous. Heavy snow moving down the mountains may pull trees and rocks along. That
can cause great damage, such as pushing down houses and killing people. Luckily, few people live in the parts of the
mountains where avalanches are most likely to happen. So not many people die from avalanches each year.
Most people who may lose their lives in avalanches are ski lovers. It’s important for them to stay safe while
having fun in the snowy mountains. Scientists can usually tell whether (是否) an avalanche might happen or not. Ifyou are a ski lover, remember to pay attention to scientists’ warnings before you go skiing.
1．Which word best describes the avalanche according to Paragraph 1?
A．Slow. B．Fast. C．Powerful. D．Dangerous.
2．What makes the old snow rush down the mountain?
A．The pressure. B．The mountain. C．The storm. D．The ice.
3．What should ski lovers do before skiing according to the passage?
A．Go and talk to scientists about avalanches.
B．Learn about how to keep themselves safe.
C．Check whether there is an avalanche warning.
D．Live far away from the mountain with avalanches.
