One evening as he was out walking,he passed an old house3he heard someone inside playing one of his compositions.As he stopped4(listen),he overheard a girl say that she5(wish) she could hear a real musician play it properly.

Beethoven went6the house and,noticing the young lady at the piano was blind,offered to play the piece for her.He did so for her for more than an hour7while he did,darkness fell and the lone candle in the room had gone out.

Outside in the night sky the8shone brightly and sent its light into the room where Beethoven sat9(play) beautiful music.He was so inspired by the appreciation of his music by the young lady and the beauty of the atmosphere in the room10he composed his famous "Moonlight Sonata."

【答案】

1practising

2known

3where

4to listen

5wished

6into/in

7and

8moon

9playing

10that

【解析】本文主要讲述了贝多芬散步时路过一个老房子,听见里面的人在演奏他的作品而且希望能够听到真正的演奏家正确地演奏,于是他便进去为屋里的盲人女子演奏了一个多小时,夜幕降临,屋里唯一的蜡烛也熄灭了,月光照在贝多芬弹钢琴的地方,他深受鼓舞,于是创作了月光曲。

1句意为:他每天花好几个小时练习音乐。Spend hours (on) doing sth 故填practising 。

2句意为:他被人们熟知。主语是he,与know是被动关系,故填known。

3句意为:一天晚上,当他出去散步时路过一个老房子,他听见有人在演奏他的作品之一。缺少连接词,定语从句修饰old house 故填where。

4句意为:当他停住听时,无意中听到一个女孩说她希望能够听到真正的音乐家正确地演奏它。Stop to do sth 停下来去做某事。故填 to listen。

5句意为:当他停住听时,无意中听到一个女孩说她希望能够听到真正的音乐家正确地演奏它。对过去的事进行描述用过去时,故填wished 。

6句意为:贝多芬走进房子,注意到钢琴旁边的年轻女士是盲人,提出要为她演奏这首曲子。走进用固定句式went into/in ,故填into/in 。

7句意为:他这样弹了一个多小时,在他弹的时候,天逐渐黑了,屋子唯一的蜡烛也熄灭了。连接两个并列的句子,故填 and 。

8句意为:外面的夜空中月光很明亮,因为是晚上所以是月光,故填 moon。

9句意为:月光照在屋里贝多芬坐着弹钢琴的地方。Sit doing sth 故填 playing。

10句意为:他因年轻女士的欣赏和屋子里美丽的氛围深受鼓舞,以至于创作了著名的月光曲。So……that,太……以至于,故填that。

【题目】A new smart phone system under development can locate you even when you’re inside a building, which GPS can't do. While the concept sounds powerful, it’s not yet clear how practical it might be.

The set-up, called SurroundSense, sends information from cameras and microphones—gear in the latest smart phones—to a server that produces a fingerprint of the location.

“You can’t tell much from any of the measurements individually, but when combined, the optical (光学的), acoustic (声学的) and motion information creates a unique fingerprint of the space,” said Ionut Constandache, a student in computer science.

The system distinguishes between two indoor spaces in this manner: It knows that a bar is likely to be dark and noisy and people move little, sit a lot, whereas a department store will be brightly lit, contain vibrant colors, and will see a lot of people moving up and down passages. The more the system is used, the more it learns about specific places.

More work is needed before the set-up would be ready for prime time, however. For now, it can’t work if a person’s cellphone is in a handbag or otherwise unable to employ the camera. Finally it would be best served if paired with phones that were worn on the wrist or hung around the neck. Batteries, too, are a problem.

Students on the research team went out across Durham, North Carolina, with their cellphones collecting data in different types of businesses. The students mirrored the actions of the selected customers so that they would not prejudice the measurements.

“We went to 51 different stores and found that SurroundSense achieved an average accuracy (精确性) of about 87 percent," Constandache said.

“As the system collects and analyzes more and more information about a particular site, the fingerprint becomes more precise,” said Romit Roy Choudhury, professor of computer engineering. “Not only is the ambience different at different locations, but also can be different at different time at the same location.”

【1】We can infer from the first paragraph that GPS .

A. can find you wherever you are

B. can make too much loud noise

C. can only find outside things

D. isn’t really practical yet

【2】Why did students mirror the actions of the selected customers?

A. To get a reasonable result.

B. To collect data in different ways.

C. To receive information about a particular site.

D. To learn more about specific places.

【3】The underlined word “ambience” in the last paragraph may mean .

A. the fingerprint of the location

B. the character of a place

C. the existence of people

D. the area of store

【4】The main idea of the passage is about .

A. comparing GPS with a smart cellphone

B. the development of cellphones

C. a cellphone knowing where you are

D. what kind of future cellphones face

【题目】Taxi-sharing could have a good effect on car numbers.

Taxi-sharing services could reduce the number of cars on the road by 75%,a study has suggested.The Massachusetts Institute of Technology (MIT) study found that a number of 3,000 four-passenger taxis could take the place of the present number of 13,000 yellow taxis in New York City.But it would mean that people would have to travel with strangers.The study was based on data from 3 million taxi rides.

Most experts who are looking at our city future agree that there is a real need to do something about the heavy traffic.Studies suggest that around the world people waste 7 billion hours each year sitting in traffic.And the effects on the environment are also severe-with cars in traffic burning 3 billion more gallons of gas.

Prof Daniela Rus from MIT's Computer Science and Artificial Intelligence Lab writes,"Instead of taking one person at a time,drivers could transport two to four people at once,leading to fewer trips in less time to make the same amount of money."The team developed a math method that could arrange cars based on real-time requests."A system like this could allow drivers to work shorter time,while also creating less traffic,cleaner air and less stressful rush hour,"said Prof Rus.Such a system would be particularly suitable for smart cars controlled by computer systems, she added.

1What's the shortcoming of sharing a taxi?

A. Passengers have to wait longer.

B. Passengers have to face strangers.

C. Passengers have to talk more.

D. Passengers have to pay more.

2What is the main cause that leads to taxi-sharing?

A. The busy people. B. The serious pollution.

C. The heavy traffic. D. The gas shortage.

3According to Prof Daniela Rus,who can also benefit from taxi-sharing?

A. The gas companies. B. The math experts.

C. The car producers. D. The taxi drivers.

4The taxi-sharing trips had better to be carried out by .

A. cars controlled by computer systems

B. cars driven by the latest robots

C. the Science and Artificial Intelligence Lab

D. the Massachusetts Institute of Technology
