【题目】If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.

“The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locks because it greatly extends the range of protection with only a few components,” Siegel explains on his website. “It is low-cost, durable and easy to use.”

The Bikealarm was designed as part of Siegel’s Bachelor’s degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thieves the moment they begin to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram / car and a serious theft.

Siegel created a working model of an alarm that would sound when it sensed movement, but wasn’t initially sure how it would be best attached to a bicycle. “I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit,” he says.

Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size.

The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasn’t signed any agreements to put it on the market.

【1】When it senses movement, the RFID Bikealarm will _____.

A. make a warning sound

B. fasten the bicycle tightly

C. shake the bicycle quickly

D. call the police automatically

【2】Which of the following shows the right position of the RFID Bikealarm on a bicycle?

A. B.

C. D.

【3】 What do we know about the RFID Bikealarm?

B. It is very difficult to use.

C. It uses a kind of battery for power.

D. It depends on Bluetooth technology.

【4】 It can be inferred from the last two paragraphs that ______.

A. the electronic circuit is a little larger

B. it’s very easy to make a Bikealarm

C. it costs too much at present

D. not many Bikealarms are produced

One year ago, I had a special English lesson hold at the railway station. It was quite different from the regular English classes we were familiar to, for we had no textbooks, no blackboard and no fixed seats.

Gathered at the entrance of the station, we told to collect as much English words and sentence as possible there. Curious and excited, we walked around the station and looked everywhere, search for any information in English. Whenever an English word comes into sight, the class wouldburstinto the cheers as if we had discovered a new world. With the Chinese translation and vividly pictures, we could figure out its meaning with ease.

Now, this unforgettable lesson still encourages me to be an active learner where I go.

I just come back from Britain last week. I was luckily enough to be one of the student from different countries to visit the UK from Feb. 16 to 28. We paid a visit to many places, like London, Oxford or the Lake District. I learned much about British culture and history in London, where was my favorite. I also liked Oxford, in which I saw much more old buildings. The Lake District was beautiful, but it was pity that it rained heavily when they were there. The most excited thing for me in the Britain was that I made a lot of friends there.

For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright “tail” of burning gas. The comet Tempel 1 has an orbit（轨道） far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface.
The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was travelling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a close-up picture which the spacecraft took just 3 seconds before it crashed into the comet.
“Right now we have lost one spacecraft,” said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion.
The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash.
The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second.The aim of the mission was to study for the first time the interior of a comet.
The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet.
（1）How many hours did it take for the spacecraft from the earth to touch the comet Tempel 1?
A.About 2,500
B.About 3,500
C.About 4,500
D.About 5,500
（2）Which of the following shows the possible orbits and positions of the comet Tempel 1?
S=solar P=Pluto T= Tempel
A.
B.
C.
D.
（3）Which of the following is the closest in meaning to the underlined word in Paragraph 5?
A.position.
B.relation.
C.inside.
D.distance.
（4）Which of the following is NOT true according to the passage?
A.The name of the space mission is called Deep Impact.
B.Deep Impact was a fantastic success but the scientist regretted losing a spaceship.
C.The crash didn't have much effect on Tempel 1.
D.The aim of the mission was to study the interior of a comet.
（5）The author's main purpose in writing the passage is to ____________.
A.inform people the discovery of a new comet
B.show the power of America in space.
C.introduce the knowledge of comets
D.introduce an experiment

People have strange ideas about food. For example, tomato is a kind very delicious vegetable. It is one of useful plant that can be prepared in many ways. It has rich nutrition(营养) and vitamin in it. But in the 18th century, Americans never eat tomatoes. They grew them in their gardens because of tomato plants are so pretty. But they thought the vegetable was poisonous. They called tomatoes “poison apples”.

President Thomas Jefferson, but, knew that tomatoes were good to eat. He was a learning man. He had been to Paris, which he learned to love the taste of tomatoes. He grew many kinds of tomatoes in their garden. The President taught his cook a way for a cream of tomato soup. This beautiful pink soup was served at the President party. The guests thought the soup tasted really well . They never thought their president would serve his honored guests poison apples. Jefferson never spoke with his honored guests about the fact.

For 80 years, Macy's Thanksgiving Day Parade has kicked off the holiday season with glorious bands, balloons and floats (花车)，and for one day, it has transformed New York City into a living comic book.
The Macy's Thanksgiving Day Parade is an annual parade presented by Macy's Department Store. It was first held in 1924. It was organized by Macy's employees, most of whom were first generation immigrants(移民)，who wanted to celebrate holidays like they did in Europe. The employees dressed in costumes(盛装)and marched on the streets with floats, bands and live animals borrowed from a zoo.
With an audience of over a quarter of a million people, the parade was such a success that Macy's declared it would become an annual event.
In 1927 Felix, the Cat became the first parade balloon to float over the city. Large animal shaped balloons replaced the live animals from then on. These giant signature(特有的)balloons are by far the biggest attraction of the parade. Each year sees parade balloons adding new characters from comic strip characters to timeless toys.
One tradition long gone is the releasing of the balloons after the parade. They would float for days and the lucky finder or finders could claim a cash reward if he or she returned the balloon or its remains to Macy's.
The parade has gone on every year except during World War Ⅱ when, aside from not having much to cheer about, the helium(氦气)air and rubber used for the balloons were needed for the war effort.
When the parade returned in 1945，it was televised in New York for the first time and also traveled its current route for the first time.
Nowadays, more than 10,000 people participate in the parade and the National Broadcasting Company(NBC) will nationwide broadcast it live from 9 a.m. to noon. The NBC has even earned several Emmy Awards for this program.
As always, the parade will end with a visit from Santa Claus. The joyful old man will get settled in Macy's Department Store after the parade to start amonthlong search for who's been naughty and who's been nice.
