Dear Volunteers，
The service you will provide to elderly individuals in Abilene as a Meals on Wheels volunteer is deeply appreciated. I want to take this opportunity to thank you for the many miles you will travel and all of the hours you will contribute to help make this one of the best programs in the entire state.
We have our staff members make a home visit before adding each person to the program and try to visit everyone at least once every year. That is hardly enough, and we depend on your contact a great deal! It is important that you report back when you do not get an answer to your knock on the door. The person inside may be hurt or ill. They may be in hospital or out of town and fail to inform us. If they are frequently absent, we may need to determine if they still need meals.
If you find someone with a medical emergency, please call 911 to request medical assistance, and then call the Meals on Wheels office. If you find someone who needs assistance other than for a medical emergency, please call the Meals on Wheels office at 6725050, and we will try to find the appropriate agency or individual to call.
Let us know when a certain person needs extra food. We have a food preparation room of shelf stable items to share with them. Please feel free to take a few magazines when you deliver meals. Many of those we serve cannot afford magazines and enjoy reading. If someone is interested in getting books from the Abilene Public Library, let us know. We can sign them up for the Books on Wheels program. Call if you smell gas strongly when you deliver meals, or if someone needs a space heater, a blanket, or an electric fan. Please convey all needs to us, and we will try to see that they are met. Some of the elderly people who we offer our service may have cancers, liver diseases, AIDS, etc. If you do not want to deliver meals to the people with certain types of health problems, such as these, please let us know.
Sincerely,
Betty L. Bradley, LBSW,
Executive Director

Unless we spend money to spot and prevent asteroids now，one might crash into Earth and destroy life as we know it，say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one，the scientists say，we'll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “If we don't take care of these big asteroids，they'll take care of us,” says one scientist. “It's that simple.”
The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.

A．They are heavenly bodies different in composition.

B．They are heavenly bodies similar in nature.

C．There are more asteroids th

an meteoroids.

D．Asteroids are more mysterious than meteoroids.

【小题2】 What do scientists say about the collision of an asteroid with Earth?

A．It is very unlikely but the danger exists.

B．Such a collision might occur once every 25 years.

C．Collisions of smaller asteroids with Earth occur more often than expected.

D．It's still too early to say whether such a collision might occur.

【小题3】 What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?

A．It sounds practical but it may not solve the problem.

B．It may create more problems than it might solve.

C．It is a waste of money because a collision of asteroids with Earth is very unlikely.

D．Further research should be done before it is proved applicable.

【小题4】We can conclude from the passage that ________ .

A．while pushing asteroids off course nuclear weapons would destroy the world

B．asteroids racing across the night sky are likely to hit Earth in the near future

C．the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime

D．workable solutions still have to be found to prevent a collision of asteroids with Earth.

Scientists are not sure how the brain follows the tracks of time．One theory holds that it has a group of cells specialized to record the intervals （间隔）of time, while another theory holds that some neural processes （神经突）act as an inside clock．

Whichever theory it may be, studies find, the cells have a poor grasp of longer interval．Time does seem to slow during an empty afternoon and race when the brain focuses on challenging work．Stimulants （兴奋剂）, including caffeine, tend to make people feel as if．time is passing faster; complex jobs, like doing taxes, can seem to drag on longer than they actually do．And emotional events — a breakup, a promotion, a transformative trip abroad —tend to be sensed as more recent than they actually are, by months or even years．In short, some psychologists say, the findings support the philosopher Martin Heidegger' s observation that time "persists merely as a consequence of the events taking place in it．"

Now researchers are finding that the opposite thing may also be true: if very few events come to mind, then the sense of time does not persist; the brain shortens the interval that has passed．

In one classic experiment, a French explorer named Michel Siffre lived in a cave for two months, cut off from the rhythms of night and day and man-made clocks．He appeared then, convinced that he had been isolated for only 25 days．Left to its own devices, the brain tends to shorten time．

In earlier work, researchers found that a similar case at work in people’s judgment of intervals that last only moments．Relatively infrequent stimuli, like flashes or tones, tend to increase the speed of the brain' s internal pacemaker．

On an obvious level, these kinds of findings offer an explanation for why other people' s children seem to grow up so much faster than one's own．Involved parents are all too well aware of first step in their own children; however, seeing a cousin's child once every few years, without bothering memories, shortens the time．

1.What can we infer from the first paragraph?

A．Scientists have agreed about how the brain records time．

B．Scientists all think that some cells record the intervals of time．

C．Scientists haven't agreed on how the brain records time．

D. Scientists all hold the theory that neural processes are an inside clock．

2.According．to Paragraph 3, if we have few things to do, the brain will____．

A．make the intervals of time long

B．make the intervals of time short

C．keep a state of rest

D．stop working

3.Which of the following is TRUE according to the passage?

A．Michel Siffre didn' t think he had stayed in the cave for as long as two months．

B．Parents tend to think their own children grow faster than others．

C．Michel Diffre actually stayed in the cave for twenty-five days．

D．Children usually bring bad memories to their parents．

4.In which column of a newspaper can we find this passage?

A．Social news B．Community activities

C．．Science D．Children s life
