2012年8月3日台风“达维”登陆威海,我市发布台风红色预警。回答题。

小题1:下列示意图中,反映上述气象灾害的是

小题2:形成该天气系统的直接原因是

A.水平气压梯度力

B.地转偏向力

C.摩擦力

D.重力

答案

小题1:D

小题2:A

题目分析:

小题1:台风属于热带气旋,北半球为逆时针旋转向里辐合,中心气流上升,对比四副图可知,D图符合要求。故选D。

小题2:该天气系统是因中心气压低,周围气压高,在水平方向上存在气压差异,产生水平气压梯度力,进而形成气旋。故选A。

点评:本题结合图示考查对台风的判断及形成的直接原因,试题难度中等,解题关键是掌握台风所属的天气系统及形成原因。

     In a few years, you might be able to speak Chinese,Korean,Japanese,French,and English-andall at the

same time. This sounds incredible,but Alex Waibel,a computer science professor at US's Car-negie

Mellon University (CMU) and Germany's University of Karlsruhe,announced last week that it may soon

be reality. He and his team have invented software and hardware that could make it far easier forpeople

who speak different languages to understand each other.

     One application,called Lecture Translation,can easily translate a speech from one language into

an-other. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Us-ers also have to be trained how to use the programme.

     Another machine can send translations of a speech to different listeners depending on what

languagethey speak. "It is like having a simultaneous translator right next to you but without disturbing the

person next to you,"Waibel said

     Prefer to read? So- called Translation Glasses transcribe(转录) the translations on a tiny

liquid-crystal display(LCD) screen.

     Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle

movements made naturally when a person is mouthing words. The signals are then translated into speech.

The electrodes could be replaced with wireless chips implanted in a person's face,according to

research-ers.

     During a demonstration held last Thursday in CMU's Pittsburgh campus,a Chinese student named

Sang Jun had 11 tiny electrodes attached to the muscles of his cheeks,neck and throat. Then he

mouthed-without speaking aloud- a few words in Mandarin (普通话) to the audience. A few seconds

later,the phrase was displayed on a computer screen and spoken out by the computer in English and

Spanish: "Let me introduce our new prototype."

     This particular instrument,when fully developed,might allow anyone to speak in any number of

lan-guages or,as Waibel put it,"to switch your mouth to a foreign language". "The idea behind the

universi-ty's prototypes is to create'good enough' bridges for cross- cultural exchanges that are

becoming more common in the world,"Waibel said.

     With spontaneous(自发的) translators, foreign drivers in Germany could listen to traffic warnings on

the radio; tourists in China could read all the signs and talk with local people;leaders of different

coun-tries could have secret talks without any interpreters there.

1.What can't be learned from the text?

A.The spontaneous translators will help us a lot.

B. There is no Muscle Translator in the world now.

2. What does the underlined word mean?

A. happening at at the same time.          

B. happening by itself.

C. similar in size.

A. To make cultural exchanges between different countries easier.

B. To help students learn foreign languages more easily.

C. To make people live in foreign countries more comfortably.

D. To help people learn more foreign languages in the future.

4. What can be inferred from the seventh paragraph?

A. The translator is so good that it can translate any language into the very language you need.

B. The translator is becoming more and more common in the world as a bridge.

C. With the help of the translator,you only need to open your mouth when you want to say

     something without saying the exact words at all.

D.The translator needs to be improved before being put into market.
