Passage 1
The Information Highway is the road that links computer users to a large number of on-line services: the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowded road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.
Passage 2
Want to know more about global warming and how you can help prevent it? Doctor Herman Friedman, who is considered a leading expert on the subject, will speak at Grayson Hall next Friday. Friedman studied environmental science at three well-known universities around the world before becoming a professor in the subject. He has also traveled around the world observing environmental concerns. The gradual bleaching (变白) of the Grate Barrier Reef, which came into the public eye in 2002, is his latest interest. Signed copies of his colorful book, which was published just last month, will be on sale after his talk.

A new eight-kilometre road is under construction that links the port area with the motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometre road tunnels are being built below the central area of the city, one for traffic to the north and the other for traffic to the south .The two tunnels are about 20 metres below the surface and are 12 metres wide, providing for two lanes of traffic in each direction.
In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electronic signs at frequent intervals (间隔). They show traffic conditions ahead, and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and , on the inside of the tunnel , a concrete lining (混凝土衬砌).
Each tunnel is roughly round and the lower part of the tunnel is somewhat flat .The surface of the road lies on the base, which is made of concrete and steel. The drainage system (排水系统), just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel, and at the level of the road surface. Other systems in the tunnel will include emergency phones .
1.Each of the tunnels under construction is ________.
A．eight kilometers long and twelve metres wide
B．eight kilometers long and six metres wide
C．four kilometers long and twelve metres wide
D．four kilometers long and six metres wide
2.Which part of the tunnel in the diagram is used to pipe out extra water?
A. 1 B. 3 C. 5 D 6
3.Driving in the tunnel , one can know the traffic conditions ahead through ________.
A．the lights B．the electronic signs
C．the trucks and cars D．the emergency phones
4.The passage is mainly about ________.
A．the construction of a road
B．the design of a road
C．the construction of two tunnels
D．the design of two tunnels

Sitting too much is linked to changes in a section of the brain that is important for memory, according to a recent study by UCLA researchers of middle-aged and older adults.
Studies show that too much sitting, like smoking, increases the risk of heart disease, diabetes and premature death. Researchers at UCLA want to see how sedentary behavior (sitting for long periods of time) influences the health of the brain, especially regions of the brain that are important to memory formation.
UCLA researchers gathered 35 people aged 45 to 75 and asked about their physical activity levels and the average number of hours per day they spent sitting over the previous work. Each person had a high-resolution MRI (热分辨磁共振成像)scan, which provides a detailed look at the medial temporal lobe, or MTL, a bruin region involved in the formation of new memories.
The researchers found that sedentary behavior is an important predictor of thinning of the MTL and that physical activity, even at high levels, is mil enough to compensate the harmful effects of silting for long periods.
“This study does not prove that too much sitting causes thinner brain structures, but instead that more hours spent sitting are associated with thinner regions,” researchers said. In addition, the researchers focused on the hours spent sitting, but did not ask participants if they took breaks during this time.
The researchers next hope to follow a group of people for a longer duration to determine if sitting cause the tinning and what role gender (性別), race, and weight might play in bruin health related to silting.
“MTL thinning can be an indication of cognitive (认知的) decline in middle-aged and older adults. Reducing sedentary behavior may be a possible target for measures designed to improve bruin health in people at risk for Alzheimer’s disease,” researchers said.
1.What is the study done by UCLA mainly intended to find out?
A. What harm sitting too much causes.
B. Why silting too much is like smoking.
C. How too much sitting affects brain health.
D. Whether too much sitting causes early death
2.Participants were scanned by a high-resolution MRI to .
A. evaluate their memory loss
B. examine their MTL conditions
C. record their physical activity levels
D. record the length of lime for their sitting
3.What do UCLA researchers think of their study?
A. It in a great success.
B. It is little practical value.
C. It must target the young.
D. It still needs to be improved.
4.What can be the best title for the text?
A. Long Sitting Is Bad for Your Brain
B. How to Improve Brain Health
C. Sitting Causes Many Health Problem
D. An Easy Way to Prevent Memory Loss

Read the following passage. Complete the diagram by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.
Since it was founded a year ago, the babysitting pool has become increasingly popular in the United States. More and more mothers have joined it and have benefited from it. What attracts them most is the idea that you pay your babysitter not in cash, but in paper cards. When you join the babysitting pool, you are given thirty cards, which are worth 30-minute babysitting time each. For each half an hour while you are gone, the babysitter gets paid one card.
There are rules regulating this service. You should not watch more than three kids at a time including your own. On big holidays, such as Christmas and Thanksgiving, the babysitter should be paid twice as much, which means two cards for every half an hour. When you leave the babysitting pool, you should return all the cards. If you are out of cards, you cannot use money instead. You should have to baby-sit for others to earn enough cards so that you will have them handy when you yourself need a babysitter.
Many mothers think highly of this service. It keeps children in constant touch with one another, and makes life easier for the mothers. Since in most cases, the babysitter is the mother who watches other kids at her own home, it is still possible for her to do her own things while the kids play with each other. In fact most mother babysitters find that their own kids are less of a monster and easier to watch when they are around other playmates. Moreover, since the babysitting pool service does not involve money, it will not be a financial loss to the family.
In the past year, the babysitting pool has helped so many mothers with their work that they all think that it is indeed a good community service worth keeping.
