题目内容

【题目】Lisa is new student from Canada, but she knows a lot about China .

A.a B. an C.the D./

【答案】A

【解析】

试题分析:句意:丽莎是一位加拿大新同学,但她对中国有很多了解。冠词作为一种虚词,只能和名词一起使用。英语中的冠词分为不定冠词和定冠词。不定冠词有两个,a an。a用在辅音开头的单词前面;an用于以元音开头的单词前。不定冠词用在单数可数名词前面,表示这个人或事物是泛指的不确定的一个,相当于中文的“一个”。定冠词和名词连用,表示某个或某些特定的人或东西。所以选A。

【题目】

There are many different houses in the world. They can be different because people are different. The houses can also be different because of where they are. Houses can be made in many shapes.

The dome house

Some people live in windy places. Big winds, like hurricanes, can blow houses down. In one place, a house was made in the shape of a dome. When a big hurricane came, it didn't blow down. However, all the other houses around it did. A dome house is made of triangle shapes. The shape of the dome house lets the wind go around it. A house with a flat wall is not as safe in a strong wind. A dome house doesn't have a roof to blow off. There is no wind in a dome house, so it is safer in a fire. It is safe from termites(白蚁),too. There is no wood for them to eat!

A ball-shaped house

Some houses have been made in a shape like a ball. The walls, celing and floor are all one in a house with this shape. The wind moves around-the outside of the house. Ball-shaped houses can be hung from things or float on water.

A house on the ground can take up a lot of space. A house in a tree doesn't use any space on the ground at all. No trees have to be chopped down to make room for these houses. And the tree housed can be built in the shape of bee nest(巢). Such a house doesn't take very long to move to a new place. So it is helpful during the natural disasters.

A walking house

Some people have made a house that can walk. It is the shape of a long hexagon. The house has six legs. It can walk over any ground. It can even walk over bumpy ground. When it walks, three legs are always on the ground. A walking house would be very good if there was a flood or a fire.

Different shapes of house are so useful that different people can choose whatever they need. Which one do you prefer? Probably you can create another different shape of house one day!
