题目内容

【题目】There is ________”h” and ________”u” in the word “hour”.

A. an ; a B. a ;an

C. a ; a D. an; an

【答案】A

【解析】

试题分析:h的词首音素是元音,故不定冠词用an。U词首音素是辅音,故不定冠词用a。选A。

冠词是一种虚词,一般用于名词前面表示特指或者泛指某一个。冠词的应用都用一定规则,熟记这些规则是解题的关键。需注意的是不定冠词的用法是看词首音素,不是看首字母,如:useful首字母是元音,但是词首音素时辅音,故不定冠词用a;hour首字母是辅音,但是词首音素是元音,故用冠词an。

【题目】

After that, we went on down the river. It was very dark that night and it wasn’t easy to see where we were going. Suddenly, a big steamboat came at us very fast, and the next minute it was right over us. Jim and I jumped off the raft (木筏) into the water. The boat hit the raft and went on up the river.

When I came up out of the water, I couldn’t see Jim anywhere. I called out his name again and again, but there was no answer. “He’s dead!” I thought. Slowly, I swam to the side of the river and got out. I saw that I was near a big old wooden house. Suddenly a lot of very angry dogs jumped out at me. They made a terrible noise and someone called from the house, “Who’s there?”

“George Jackson,” I answered quickly. “I’ve fallen off a river boat.”

Well, the people who lived in that house were very kind, and they took me in and gave me some new clothes and a good meal. I told them that my family were all dead, so they said I could stay with them as long as I wanted. It was a beautiful house and the food was good there, so I stayed.

A few days later one of the slaves in the house came to me and said, “Come with me!” Together, we went down to some trees by the river. “In there!” he said and went away.

On the ground, I found a man, asleep. It was Jim! I was really pleased to see him. When the steamboat hit the raft, Jim told me, the raft didn’t break up. Jim swam after it and caught it. Then he began to look for me.

We decided to leave at once. It’s all right living in a house for a little while, but you feel more free and easy and comfortable on a raft.

【题目】We brush our teeth every day but few people know how well we’re brushing. Today, a French company has introduced an electric toothbrush, which can work wirelessly (无线地) with a smartphone.

It’s called the Kolibree toothbrush. It has different models, and will cost from $99 to $200.

Users download an app and connect via Bluetooth, and the Kolibree will record 1) the time you spent brushing teeth, 2) whether all areas of your mouth are reached, 3) whether you brush up and down instead of just side to side. Then it will send the information to a mobile phone via Bluetooth, telling you whether you have brushed in a proper way. The Kolibree app records your progress and scores your brushing way to help you improve brushing habits.

The toothbrush will also be able to talk to other apps on your phone, so developers could create a game controlled by your toothbrush. That would be very interesting.

The Kolibree toothbrush was invented by Thomas Serval. He says the idea of inventing it came from his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They always answered “yes”, but Thomas used to find their toothbrush

heads dry. He decided that a kind of brush was needed to tell him how well they brushed their teeth. Thomas says that one day, it’ll be possible to use a brushing unit with a camera. The camera can even examine holes in your teeth while you brush.

【题目】Umbrellas are certainly one of life's necessary handy helpers. But as anyone ever caught in a heavy rain will tell you, they're far from perfect. So, many creative designers made efforts to challenge. Here are four clever designs that can solve the rainy day problems.

Senz

Common umbrellas love to invert(翻转)when it's windy. The Senz umbrella changes the round shape into the one that's long in the back and short in the front. The design is much stronger against even strong winds, and according to their tests, the Senz works well.

Nubrella

An American named Alan Kaufman and his company spend 6 years inventing this hand-free umbrella. The hand-free umbrella is called Nubrella. The umbrella can rest on the user's shoulders. So the user needn't hold the umbrella any more. And it's convenient to make a phone call or ride a bike without an umbrella in the hand.

Kazbrella

There is no doubt that this kind of umbrella is the shining star in the umbrella market this year. Common umbrellas drip(滴水)everywhere when they are closed. Kazbrella tries to solve this problem in a special way. Though it looks like common umbrella, the design allows the wet side of the umbrella to be inside once you fold it. As a result, getting in and out of your car is not a problem.

Rain Shield

In the face of a heavy rainstorm, rain can hit you from all directions. Rain Shield gives the protection from the sideway rain and its bendy(弯曲)design means it won't invert. It can handle strong wind. When not in use, it folds into a small piece.

A. are useful but not perfect enough B. can only be used in a heavy rain

C. can protect us very well in a heavy rain D. are challenges for creative designers

3If you use Rain Shield in a heavy rainstorm,__________________________________.

C. it will prevent neither rain nor wind D. it's easier to get in and out of the car

4Which sentence is WRONG according to the passage?

A. Senz is easy to hold with its special shape even in windy weather.

B. Nubrella is a great idea for those who want to play sports on rainy days.

C. Kazbrella opens from the inside out and keeps dry when you carry around.

D. Rain Shield sells best with the special shape and it folds into a small piece.
