听力原文： M: It looks like there is going to be a shower any minute now.
W: I think so too. Isn’t it strange how you can sense it？
M: I know what you mean.
W: Look at the clouds in the sky. Whenever they seems dark and low like this, you know it’s going to rain. Or look at the object that’s far away. If it seems clear to you, it’s going to pour.
M: Yes. And everything seems to have a strange smell to me then.
W: I know. And people often say it’s going to rain when they have aches and pains in certain parts of their body. My mother always complains that her knee hurts just before a storm.
M: And have you ever noticed how the animals act before a storm？
W: Sure. Horses and cows always seem to go to a protected area and huddle together.
M: Yeah. But with all these sensible signs, how can we carry an umbrella with us now？

B．How to treat minor aches and pains.

听力原文： There is nothing quite so depressing as a house which has been shut up for a period of time. Even if it has been kept dusted and clean, there is still a musty smell and a feeling of airlessness about the rooms. No warmth seems to come out from the electric fire one has just switched on, no light through the window from which one has just down to the curtains. The chairs in the sitting-room look as if they has never been sat on, even if they are far from new. They are arranged in neat patterns round the coffee table. Not until you drop your coat or the newspapers on them do they begin to look as anything normal. As far as the kitchen, that is the least attractive place of all. Although it hasn't been used for months, it still seems to smell vaguely of some old food. The kitchen table is clean, the cupboards are bare. You cannot remember where the gas and the water turn on, the cups all seem to have lost their handles, the plates seem to be cracked, and it is impossible to find a teaspoon anywhere.

听力原文： Are electric cars the way of the future？Automobile manufactures are under pressure to develop cars that do not pollute.One powerful motive is a California law requiring that by the year 2020 ten percent of new car sells in the state be so called zero-emission vehicles.These cars must put no pollutants whatsoever into the at-mosphere.
California is a huge market for the automobile companies,so they are working hard to meet these standards. So far the electric car seems to be the best alternative.So the big advantage of electric cars is that they don't pollute.However they will be in competition with gas-powered cars and that's where the weaknesses come out.The big problem is that the batteries that power electric cars weigh a lot relative to the amount of power they deliver.For instance,in one prototype electric car,the batteries weighed 400 kilograms.And they provide enough energy to go 250 kilometers before recharging,which takes eight hours.Compare that to a moderately fuel-efficient conventional car,it can go 600 to 700 kilometers on a tank of gas and refilling takes just minutes.If there are other drains on an electric car's batteries besides the motor,headlights,air-conditioning or a heater,its already limited range will be significantly reduced.So automobile engineers are trying to make more powerful batteries that would increase the cars'range and make them more attractive to buyers.
Why does the electric car seem to be the best alternative so far？
A．It is comfortable.
B．It is best made.
C．It causes no pollution.
D．It makes less noise.

M: I know what you mean.
W: Look at the clouds in the sky. Whenever they seem dark and low like this, you know it's going to rain, or look at the object that's far away, if it seems clear to you, it's probably going to pour.

W: I know, and people often say it's going to rain when they have aches or pains in certain parts of their body. My mother always complains that her knee hurts just before a storm.

W: Sure, horses and cows will seem to go to a protected area and huddle together.
M: Yeah, but with all these sensible signs, how come we aren't carrying our umbrella with us now？

Psychologists have noticed that larger units of time. such as months and years, fly on swifter wings as we age.
They also note that the more time is structured with schedule and appointments, the more rapidly it seems to pass. For example, a day at the beach. Since most of us spend fewer days at the beach and more at the office, an increase in structured time could well be to blame why time seems to speed up as we grow older.
Expectation and familiarity also make time seem to flow more rapidly. Almost all of us have had the experience of driving somewhere we've never been before. Surrounded by unfamiliar scenery, with no real notion of when we'll arrive, we experience the trip as lasting a long time. But the return trip, although exactly as long, seems to take far less time. The novelty of the outward journey has become routine. Thus taking a different route on occasions can often help slow the clock.
When days become as identical as beads(珠子) on a string, they blend together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day--to stop time, so to speak.
Learning something new is another way to slow the passage of time. One of the reasons the days of our youth seem so full and long is that these are the days of learning and discovery.
The purpose of this passage is to ______.
A．show the different ideas of physicists and psychologists on time
B．state the principles of time
C．describe various notions about time
D．explain why time flies and how to slow it down

听力原文：M: I am really excited at the prospect of starting my coming holiday!
W: It sounds good. It's a good idea to have relaxation after working so long.
M: Yes. I've been looking forward to it for ages. It seems such a long time since I had a holiday.
W: Then, what do you plan for the coming holiday？
M: You know, I have two kids. Both of them are keen on the idea of going camping.
W: Sounds great! Children are often active and like to have an adventure.
M: Absolutely. I like the idea, too.
W: You haven't decided where to go yet？
M: No, not exactly. Going abroad requires a large sum of money and I cannot afford it at the moment. Most probably I will choose a place not far from here so that we can go on a cycling tour.
W: Twenty days will be enough for your family to enjoy yourselves.
M: It would be far better if we could have a longer holiday. The holiday will last only two weeks. So we must seize every day to relax ourselves.
W: Still, two weeks is not bad. At least you are luckier than I am. We seldom have holidays because the bank seldom provides holidays for people who work for it.
M: As a teacher, I always keep busy with my teaching work and other work in the school. But the holiday provided by the school is good enough to recover my lost energy and give me refreshment.
(23)
A．Hiking.
B．Having a picnic.
C．Camping.
D．Fishing.

听力原文：W: So, what do you think of this place？
M: Well, I like the location, but it seems a bit darker than the other flat, don't you think？
W: Yes, you might be right, but that's because the walls are painted a darker colour, right？
M: You have a point there. If we can paint them a brighter colour…The rooms are not quite as spacious.
W: That's true, but there is an extra room. We could use that for storing items that we don't often use and our bicycles.
M: Good idea. There aren't so many stairs to climb either. As usual the key thing is money. This place is a little more expensive than the other one. Can we stretch our budget this far？
W: I think we can. Actually, I'm thinking less about the rent and more about the time we'll save getting to and from university.
M: Yes. We've both got part-time jobs, so we won't have any financial difficulties. We'll just save a little less, that's all.
W: What do you think of the landlady？ She seems OK to me.
M: Yeah, she seems fine. Let's ask her about the painting. We can offer to do it ourselves and pay for the paint. I don't see how she could object to that.
W: Are you any good at painting？
M: My middle name is Picasso!

Many companies in the United States have been moving jobs to countries where costs are much lower. Factory production jobs have moved away for years. But the jobs now also involve skills like computer programming.
Labor groups and workers are angry. They point to reports that say the United States has lost two-and-a-half million jobs since two-thousand-one. Most were jobs in manufacturing. Some states have lost more jobs than others. But no one seems to know for sure how many jobs left the country.
There was a recession. Jobs were cut. Yet, so far, the economic recovery has produced fewer jobs than expected. So outsourcing has created an emotional debate.
What's the purpose of outsourcing？
A．Recruiting new staff.
B．Producing quality products.
C．Increasing productivity.
D．Save money and labor cost.
