【题目】Where she from?

A. does; come B. is; come C. does; comes

【答案】A

【解析】句意:她来自哪里?表示来自……”有两种说法:come from和be from,二者所构成的句型是不一样的,本题用的是come from结构,由它可构成主谓宾句子结构,原句中没有be动词,故其问句不能提前be动词,要借助于助动词do/does来构成,主语是she,要用does,故选A。

【题目】

At night, you fall asleep while listening to beautiful music.1You can enjoy all of these things because of one important organ (器官) — the ears. March 3 is Ear Care Day. It helps us remember the importance of our ears and encourages us to take good care of them.

You may wonder: how do the ears work? The ear has three different parts: the outer ear, the middle ear, and the inner ear, The outer ear is the part you can see.2The sound then travels down to middle ear, the inner ear and then to your brain.

3Your ears keep on hearing sounds, but your brain just ignores them. That’s why you may sometimes wake up suddenly in the middle of the night — your brain heard something, but you don’t know what it was, since you were asleep.

But ears do more than hear.4In the inner ear, there are organs that are filled with liquid and covered in small hairs. When you move your head, the liquid and hairs move, too. They send messages to your brain about the position (位置) of your head.

More surprisingly, ears even help with tasting food.5But there are nerves ( 神经) running through the middle ear that connect the tongue to the brain.

The ears are truly important organs with many functions (功能). Everyone should make sure to protect their own ears as well as they can.

A. Of course, you don’t actually taste food with your ears.

B. Your ears never stop working, even when you are asleep!

C. In the morning, you are woken up by the singing of birds outside.

D. They help you keep your balance, too.

E. It collects sound around you.

【题目】 For many years scientists have said that the earth is getting warmer. Now they have found something new-hot cities! In the southern US, they have found that cities become very hot in summer.

China also has the same kind of problems. Every year more farming land is used for factories or offices. More housing is needed too. As people become richer, they buy more cars. New roads are needed and new car parks are built in the city centres. This all makes the cities hotter.

It is not easy to change the situation(情形). City planners say that we should plant more trees in the middle of cities. ‘Every new street should have trees on both sides,’ they say. Trees make the temperature(温度) lower, so we should have more trees in our parks and squares. Also we should paint our roofs(屋顶) white. If we do this, they do not become so hot. Every roof in a hot and sunny country should have solar(太阳的)roof panels(板). The electricity from these can be used to run the air conditioners in the building.

People continue(继续) to cut down forests around the cities. This makes the problem worse. Cities are growing faster and faster. By the year 2050, 80% of the world’s population will be living in cities. If we go on like this, there will not be enough farmland to feed everyone in the world.
