There are various reasons why cancers appear to be on the increase. For one thing, though their sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their middle and advanced years. Naturally, since people live longer these years, there are more cancer sufferers than before. Again, with better methods of diagnosis (診斷), doctors can more easily recog??nize cancerous growths that would formerly have passed unnoticed or that would have been wrongly di??agnosed. It is also believed that certain habits and conditions of modem living, including heavy smok??ing and the pollution of the air, may leave people living in more cancer-causing conditions than before.

We all look forward to the day when a simple medical test can find cancer while it is still small. Researchers around the world are working on such a test. Most of their work deals with the examina??tion of the blood.

Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.

The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.

The test examines very small bits of fat in the blood called lipids (脂質(zhì)). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.

The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.

1. Who will fail cancer from the study of the researchers?

A. The young.                           B. The middle age and the older.

C. The man.                                    D. The woman.

2. The underlined words "such a test" refer to________.

A. the test that shows which persons have cancer and which don’t     .

B. the test that may be able to show cancer very early in its development,.

C. a simple medical test that cannot find cancer when it is -small

D. a new test that could be a step to develop a difficult way

3. Which of the following statements is true according to the passage?

A. Cancers have much to do with something in patients’ blood.

B. People living in better conditions are most likely to be attacked by cancer.

C.X-raying is the best way to determined whether a person has cancer or not.

D. Cancers have nothing to do with a person’s habits and living conditions.

4. What would be the best title for the passage?

A. A simple way to cancer                 B. Cancers can be cured

C. How to find cancer                            D. Early discovery of cancer

I HEAR America beeping(嘟嘟響)．

 Beep，says my cellophane when it gets a text message．

  Beep，says my microwave oven when my sandwich  is warmed up． 

 Sometimes  I long for a natural sound：a bird singing，dog barking，children laughing， anything to drown out  the maddening beeps that have become the soundtrack(配樂)to modern life．

  My cellophane? It isn’t enough that its ring tone offerings seem to stretch from  “annoymg” toextremely “annoying”． It also has to beep whenever someone texts messages me． 

The microwave? A bell rings when it's finished heating my food．But is that enough? No．If I don’t rush to it right away, it starts beeping，like an impatient child tugging(用力拉) at my sleeve(袖子)．

 The smoke detector(探測器) is the worst offender．When its batteries are in need of replacement，it 1ets out a series of chirps．The things that don’t beep buzz(嗡嗡響)．And for some reason，beeping and buzzing is beneath them，they clear their throats and perform a symphony． Like my TV, each time I turn it on, it performs an aria(詠嘆調(diào))：La di da di dum．Salutions! Here I am! Same thing when I turn it off: La di da di dum．Good bye, kind sir! Until the next time

But at 1east I know where each of these sounds is coming from．That isn’t always the case．For weeks, my wife and I were awoken in the night by a beeping．There，in the stillness， we went through the possible suspects．Could we have a text message? Could it be any of the devices(裝置)able to make a sound? Curling iron, rice cooker, smoke detector, TV set，clock radio．．．

The only way to tell was to chase the sound down ，but no sooner  would we pull on our bathrobes than the beeping would stop. We didn’t hear it every night but often enough that we would climb into bed wondering whether our sleep  would be interrupted by that maddening sound，that beep．

  Finally,early one morning，my wife found it：in the study,under a desk，a big plastic cube that was plugged into the wall．It was an uninterruptible power supply that we’d inherited(繼承)from my wife’s mother．We’d never known it was capable of speech． 

I think it just wanted someone to talk to.

14．What does the writer truly mean by saying“I hear America beeping”?

A．American people like devices that beep．

B．Americans are crazy about sending text messages．

C．In modern society people are dependant on technology．

D．The soundtrack to modern life is no longer natural．

15．Why couldn’t the author and his wife find the source of the noise in their house in the beginning?

A．There were too many devices for them to check．

B．They were unwilling to get up at midnight．

C．They had never known that thing could beep too．

D．The noise didn’t come every day．

16．After reading this passage，we can probably tell the author    ．

   A．enjoys being surrounded by beeps  B．has a touch of humor in his writing

C．tries to avoid using anything that beeps

D．understands the beeping is designed to be user-friendly

D
I wrote to the White House asking about a birthday greeting for my grandfather who will be 95 next year. I received a card signed by Bill and Hillary. They look like real signatures（簽名）and are not printed and they are probably produced by autographing（親筆簽名）machines. That says:
Happy Birthday!
Hillary and I are delighted to join your friends and family in congratulating you on this special day. As you look forward to the year ahead, please accept our best wishes for good health and much future happiness.

The outer envelope does have a little "B" written on the upper right corner indication that they have a pile of these pre-signed and double-enveloped; when a request comes in, they just write the address on the outer envelope and mail it.

Institute
Not Doing Much is the best organization in the world. You know how to avoid unnecessary activities!
     We closely followed the advice in your article. First, we replaced all our telephones with carrier
pigeons. Simply removing the jingle of telephones and replacing them with the pleasant sounds of birds
has had a remarkable effect on everyone. Besides, birds are cheaper than telephone service. After all,
we are a business. We have to think of the bottom line. As a side benefit, the birds also fertilize the lawn
outside the new employee sauna.
     Next, we sold the computers of, to Stab, Grab, Grit, and Nasty, a firm of lawyers nearby. Our
electricity bill went way down. Big savings! The boss is impressed. We have completely embraced paper
technology. Now that we all use pencils, doodling is on the increase, and the quality of pencilwomanship
is impressive, as you can tell from my handwriting in this letter. By the way, if you can, please send this
letter back to us. We can erase and reuse it. Just tie it to Maggie's leg and she'll know where to take it.
     Now it's very calm and quiet here. You can notice the di fference. No more loud chatter on the
telephones! All we hear is the scratching of pencil on paper, the sound of pigeons, and the delivery of inter-

it's perfect.
