【题目】To: David Rodgers

From: Mavis Chen

Subject: getting back our old subscribers

Since the marketing meeting yesterday, it occurred to me that we might be ignoring one potentially important source of subscribers. We have focused so intently on how to expand the appeal of our product to groups that have never used it before that I’m afraid we may have overlooked the obvious we may have forgotten that there is a whole group of interested people who have used it and stopped for one reason or another.

This target group has particularly good potential because it consists of readers who have demonstrated interest in the subject matter we present. Their interest is not something we have to work to stimulate. I suggest that making a maximum effort to win these readers back will be more effective on a percentage basis than pursuing some of the other groups we’ve identified.

Since these readers quit using our product once, they were most likely dissatisfied with some aspect of our presentation or our pricing. Our new product will be vastly improved over the old version and is priced more competitively. We need to do everything possible to get those points across, perhaps by sending them a free issue and by asking for their opinions on how we might improve it even further. This could be in the form of a very short survey, either included with the free issue or accessible online.

If you think this idea has merit and might be willing to authorize it, let’s discuss it further when you’ve got a few spare minutes. I have a rough draft of the survey questions I could show you.

1What kind of product is the writer referring to in the memo?

A.A web-based information service.B.A magazine.

C.A consulting service.D.Computer software.

2Why is the writer confident that they can win back their old customers?

A.Their product has no competition.

B.Their product has changed dramatically.

C.They have reduced the price of their product

D.The need for their product has increased.

3What does the writer want to do?

A.Start her plan immediately.B.Wait for input from the survey.

C.Get Mr. Rodgers’ approval.D.Present her idea in the next meeting.

【题目】 No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting. For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. Many people feel in their bones the coming of wet weather, their joints(关节) hurt. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because the insects which they are hunting fly low. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in color, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.

1People’s joints ache ______.

A.is a sign of coming rainB.without any reason

C.because they are illD.because of the insects

2The birds fly high and the stars twinkle clearly is a sign that the weather will ______.

A.be warmB.be rainy

C.become clear and fineD.be cold

3We must ______ to make weather forecasting.

A.use our eyes and brainsB.study the weather hard

C.read correctly the signsD.All of the above

【题目】Self-respect is very important for a great life. If we lack self-respect we will be unsure of ourselves and try to be someone we are not. The following are some ways we can improve our self-respect.

1 There is great pressure from parents, work and society to become a certain person and to achieve certain things. But, real self-respect only comes from being true to our inner calling. It is important that you have faith (信念) in your own values and remember what is important to you.

Respect others. If you have no respect for others, how can you have self-respect? 2

Learn to deal with criticism (批评). When we are criticized, we feel bad about ourselves. So to keep a sense of self-respect, we need to learn how to handle criticism. 3 If there is some truth in it, we can use it to develop our character.

4 Our appearance is important. It can give us confidence or it can make us feel ashamed. Dressing smartly gives us self-confidence. Dress for your own benefit. Don’t dress in the hope of pleasing others and receiving praises.

Never dislike yourself. We make mistakes or we may do the wrong thing. 5 We should never hate ourselves.

A.Try to be selfless.

B.Be true to yourself.
