【题目】

Global Positioning Systems are now a part of everyday driving in many countries.These satellite-based systems provide turn-by-turn directions to help people get to where they want to go.But,they can also cause a lot of problems, send you to the wrong place or leave you completely lost.Many times,the driver is to blame.Sometimes a GPS error is responsible.Most often,says Barry Brown,an expert in human-computer interaction,it is a combination of the two.

We spoke to Mr Brown by Skype (网络电话软件).He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPS-equipped car to use during his stay.Barry Brown:“And they just plugged in an address and then set off to their destination.And,then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address ia So again,the GPS is kind of 'garbage in garbage out'”.

Mr Brown says this is a common human error.But,he says,what makes the problem worse has to do with some of the shortcomings,or failures,of GPS equipment.Barry Brown:“One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn,sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place.

Barry Brown once worked on a project with Eric Laurier from the University of Edinburgh.The two men studied the effects of GPS devices on driving by placing cameras in people's cars.They wrote a paper based on their research.It is called “The Normal,Natural Troubles of Driving with GPS”.It lists several areas where GPS systems can cause confusion for drivers.These include maps that are outdated,incorrect or difficult to understand.They also include timing issues related to when GPS commands are given.

Barry Brown says to make GPS systems better we need a better understanding of how drivers,passengers and GPS systems work together.

1In Paragraph 2,Mr Brown mentioned his friend in the conversation to .

A.build up his own reputation

B.laugh at his stupid friend

C.prove the GPS system is only garbage

D.describe an example of human error

2Which of the following statements would Barry Brown most likely agree with?

A.GPS units are to blame for most GPS service failures.

B.We should introduce higher standards for the driving license.

C.Cameras are urgently needed to help improve GPS systems.

D.Drivers,GPS systems and passengers should unite to improve GPS systems.

3What is Mr Brown's attitude towards GPS?

A.Unconcerned. B.Prejudiced. C.Objective. D.Critical.

4What would be the best title for the text?

A.Driving with GPS can be difficult

B.Driving confuions can be caused by small screens

C.Driving without GPS should be much more convenient

D.GPS equipment in driving:to be deserted or improved?

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

【题目】Are you always disturbed by the noise made by your coworkers while you’re working hard at your task? What kind of feelings will you have on hearing such kind noise? Have you ever got an idea that a certain helmet will help you out of the trouble no you can focus on your work at the office? Now, you needn’t worry for the “Helmfon” will help you ignore noisy co-workers and other distractions.

Created by Ukrainian design company Hochu Rayu, the Helmfon is a big helmet that uses special equipment to absorb the sound so as to completely block out any outside noise, giving the wearer their own quiet personal space so they can better focus their attention on their work. Made of a glass fiber shell, cloth and polyethylene(聚乙烯), the helmet not only blocks outside sound, but it also keeps the noise you make in, allowing you to answer calls, hold Skype conferences, watch or edit videos, privately.

The company came up with the idea for the Helmfon after being asked to design a new phone booth for an IT company. The project made the team think about the way we communicate and finally begin work on a device that would allow you to be in two worlds just sitting on your chair in the office, in a meeting, or everywhere you feel like just wearing your helmet.

The Helmfon comes complete with a system board, microphone, speakers, and a special holder for your phone. The only trouble is that it makes you look like a character from Mel Brooks famous movie Spaceballs, but the company also made public a variety of great choices, including Bat man-inspired design, and even a Native American headgear.

The Helmfon is still in prototype(维形)stage, but the Ukrainian company is already working on a commercially available design and plans to offer the design for sale. A release date has not yet been made public.

You may like chewing gum (口香糖) after meals to stop your breath smelling bad; or your mother might use a special neutralizer (调理剂) to protect her permed hair (烫发). But have you thought about the chemical principles behind such everyday actions?
On March 2, the Senior 3 students from the IB (International Baccalaureate, 国际文凭) classes at Beijing Huijia Private School presented their discoveries, all in fluent English. This kind of seminar is held every year to show the achievements of the IB chemistry experiment lessons offered by the school. IB is a qualification based on a common curriculum (课程) for students aged 16-18 in any country and is recognized by universities everywhere.

"Once I saw an advertisement for xylitol (木糖醇) gum," recalled Zhang Xinju. "Suddenly an idea came to my mind: are there any chemical reactions when the xylitol is working on our teeth?"
Zhang and his partner Bu Xuan visited several hospitals to try and find out. "Doctors know that xylitol can protect teeth, but few could explain how the chemical reactions happen," said the 17-year-old boy.
Presenting the results of their research in English to an audience of Chinese and foreign judges was never a problem for the students.
"Textbooks for IB students are in English, and our teachers speak in English," explained Wei Duan and Han Yu, whose research topic was "The Acid-Base Reaction (酸碱反应) in the process of Hair-Perming".
"In Senior 1 we often referred to Chinese textbooks, but we found we could understand and express it all in English by the second year."
Lu Jiang, the school's IB chemistry teacher and China's only IB vice-examiner, is proud that her students can apply scientific theories they learn in class to daily life.
"You might have learned these facts from you kindergarten teachers, but few think about the theories behind them," Lu said. "This kind of practice is intended to develop the scientific thinking they will need in their future studies."
(1)IB is recognized by____________.
A.Beijing Huijia Private School
B.univercities in China
C.schools in Engkish-speaking countries
D.universities in any country
(2)which statement is true?____________
A.Doctors don't know that xylitol can protect teeth
B.Doctors can explain how the chemical reactions happen
C.Few could explain how the chemical reactions happen.
D.The foreign doctors can explain how the chemical reactions happen
(3)Textbooks for IB students are in___________

【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?

A. It can’t tell between specific events.

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
