Dear Sirs,
We have been very pleased with your product, as you know.However, we find that we can obtain a price of $4.00 per hundred with a local firm.This is fifty cents per hundred lower than your price.
If you can see your way clear to meeting these figures we would be pleased to place with you an order that will carry us for the rest of this year.That order is likely to be one of the largest that we have ever placed with you.
Sincerely,
英译汉: 2. (本小题只翻译有下划线的句子) It has become increasingly clear that the United States must find methods to control inflation, probably the single problem that most worries the average American. President Jimmy Carter noted that inflation is the cruelest tax that anyone can pay. Many people agree with that statement, arguing that the persistent decline in the dollar’s purchasing power hurts people directly because products cost more, and also causes a kind of psychological damage. Recent polls have shown that the average American, far from being optimistic, expects prices to rise to ever higher rates.
The usual way to ensure reliable delivery is to provide the (71) with some feedback about what is happening at the other end of the line. Typically, the protocol calls for the receiver to send back special (72) flame bearing positive or negative (73) about the incoming frames. If the sender receives a positive acknowledgement about a frame, it knows the frame. has arrived safely. On the other hand, a negative acknowledgement means that' something has gone wrong, and the frame. must be transmitted again.
An additional complication comes from the possibility that hardware troubles may cause a flame to (74) completely. In this case, the receiver will not react at all, since it has no any reason to react. It should be clear that a protocol in which the sender transmits a frame. and then waits for an acknowledgement, positive or negative, will hang forever if a frame. is ever lost due to, for example, (75) hardware.
A.receiver
B.controller
C.sender
D.customer
According to paragraph 4, it was difficult for Smith to distinguish rock strata because
A.the rocks from different strata closely resembled each other
B.he was often unable to find fossils in the younger rock strata
C.their similarity to each other made it difficult for him to distinguish one rock type from another
D.the type of rock between two consistent strata was always the same
Because it was isolated and because the weather was almost always clear and peaceful, a spot of desert near Alamogordo was chosen as the last site for the first atomic bomb ever exploded. The secret name of the test was Zeo.
At dawn on July 16, 1945, the atomic bomb was set off. Observers agreed that they had witnessed something unlike anything ever seen by men before, a huge, colorful fireball, more brilliant than the sun flashing as it rose for miles into the air. Never before had men released so much power at one time, nor had any nation ever possessed weapon as terrible and destructive as the atomic bomb.
For several weeks, the test was kept secret. When an atomic bomb was dropped from an American plane on Hiroshima, Japan, newspapers and radio stations all over America told of the test of the bomb in New Mexico. Almost everybody was amazed to learn where the bomb had been made and tested; the deserts of the Southwest had hidden the secret well.
When news of the atomic bomb and its destructiveness was announced, people all over the world wondered what other new weapons were being prepared in the New Mexico desert. Some people doubted that the secret of making atomic bombs could be kept from other countries. Some even doubted the wisdom of using so powerful a weapon. But no one doubted that a new kind of war—and a new kind of world—had begun at Alamogordo, one summer morning in 1945.
第36题:What is the main topic of this passage?
A) The secret of Alamogordo.
B) A new kind of war.
C) The destructive force of the first atomic bomb.
D) The selection of the test site for the first atomic bomb.
(79) There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement. We might ask whether the cost of advertisement is paid for by the producer or by the customer. Since advertisement forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for the advertisement. How ever, if large—scale advertisement leads to increased demand, production costs are reduced, and the customer pays less.
It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to in crease demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. (80) What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them.
Advertisement is often used to ______.
A.deceive customers
B.increase production
C.arouse suspicion
D.push the sale
With Mars the scientific benefits are perhaps higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by accumulating evidence that Mars once had abundant liquid water and by the controversy over suggestions that fossils of bacteria rode to Earth on a rock ejected from Mars during its early history. A definite answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. The revelation that life arose independently on Mars and on Earth would provide the first concrete clue in one of the deepest mysteries in all of science: how prevalent is life in our galaxy?
One of the reasons why the idea of sending people to Mars strikes a chord in so many people is that it is already possible—the U.S. has the money and the fundamental technology needed to do it. More important, recent discoveries about the planet's environment in the distant past have presented a clear and compelling scientific incentive for sending people: to search for evidence of life. The thesis that liquid water was once stable on Mars has been strengthened by aerial photographs taken last year that showed what appeared to be a drainage channel cut deeply by water flowing for hundreds if not thousands of years.
A thorough hunt for any life on Mars that might be hanging on—despite the present deficit of water—would also have to be undertaken by humans, according to some experts. Such life will be hidden and probably tiny. "Finding it will require surveying vast tracts of territory," one expert explains. "It will require the ability to cover long distances and adapt to different conditions." Robots might be up to the task sometime in the distant future, making human explorers redundant, he concedes. But relying on them to survey Mars during periodical missions to the planet would take a very long time—"decades if not centuries," he believes.
Which of the following may be the reason for humanity's exploring?
A.Some urgent needs.
B.Profit or national pride.
C.Economic benefit and national glory.
D.International competition in space.
Another fragmented idea concerns the planet's seasonal changes in color. Once attributed to the rapid spread of some life-form, these shifts are now known to develop from the movement of fine dust in the atmosphere.
By the close of the 20th century none of the many experiments conducted by spacecraft had ever found persuasive evidence of life. Nevertheless, speculation continued over the existence of some form. of life, in either the present or the past. In 1996 scientists discovered organic compounds and minerals in a meteorite(陨石), consisting of Martian rock, that collided with Earth around 11,000 B.C. These compounds suggest that Mars may have been inhabited by organisms more than three billion years ago.
Why did people in the 19th century believe the existence of intelligent life on Mars?
A.Because the surface of Mars seemed to be geometric.
B.Because the lines were drawn across the surface of the planet.
C.Because a system of canals was thought to be there.
D.Because it was the Martians that built the canals.

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?
What is the main topic of the conversation?
A.How to select a good umbrella.
B.How to treat minor aches and pains.
C.How to sharpen the senses.
