I am a German by birth and descent. My name is Schmidt. But by education I am quite as much an Englishman as a 'Deutscher', and by affection much more the former. M
y life has been spent pretty equally between the two countries, and I flatter myself I speak both languages without any foreign accent.
I count England my headquarters now: it is “home” to me. But a few years ago I was resident in Germany, only going over to London now and then on business. I will not mention the town where I lived. It is unnecessary to do so, and in the peculiar experience I am about to relate I think real names of people and places are just as well, or better avoided.
I was connected with a large and important firm of engineers. I had been bre
d up to the profession, and was credited with a certain amount of “talent”; and I was considered—and, with all modesty, I think I deserved the opinion—steady and reliable, so that I had already attained a fair position in the house, and was looked upon as a “rising man”. But I was still young, and not quite so wise as I thought myself. I came close once to making a great mess of a certain affair. It is this story which I am going to tell.
Our house went in largely for patents—rather too largely, some thought. But the head partner's son was a bit of a genius in his way, and his father was growing old, and let Herr Wilhelm - Moritz we will call the family name—do pretty much as he chose. And on the whole Herr Wilhelm did well. He was cautious, and he had the benefit of the st
ill greater caution and larger experience of Herr Gerhardt, the second partner in the firm.
P
atents and the laws which regulate them are strange things to have to do with. No one who has not had personal experience of the complications that arise could believe how far these spread and how involved they become. Great acuteness as well as caution is called for if you would guide your patent bark safely to port—and perhaps more than anything, a power of holding your tongue. I was no chatterbox, nor, when on a mission of importance, did I go about looking as if I were bursting with secrets, which is, in my opinion, almost as dangerous as revealing them. No one, to meet me on the journeys which it often fell to my lot to undertake, would have guessed that I had anything on my mind but an easy-going young fellow's natural interest i
n his surroundings, though many a time I have stayed awake through a whole night of railway travel if at all doubtful about my fellow-passengers, or not dared to go to sleep in a hotel without a ready-loaded gun by my pillow. For now and then - though not through me - our secrets did ooze out. And if, as has happened, they were secrets connected with Government orders or contracts, there was, or but for the exertion of the greatest energy and tact on the part of my superiors, there would have been, to put it plainly, the devil to pay. The writer preferred to be called ________.
| A．a German | B．an Englishman |
| C．both a German and an Englishman | D．neither a German nor an Englishman |
Which of the following words cannot be used to describe the writer?
| A．Talented | B．Modest | C．Reliable | D．Wise |
The head of the company where the writer works is ________.
| A．Schmidt | B．Moritz | C．Wilhelm’s father | D．Gerhardt |
The writer often stayed awake on the train or kept a ready-loaded gun in the hotel, because ________.
A．some peo ple sometimes let out the secrets of his company |
| B．the writer occasionally didn’t keep the secrets of his company |
| C．patents and the laws are strange things to have to do with |
| D．the secrets were connected with Government orders or contracts |
Believe it or not, optical illusion(错觉) can cut highway crashes.
Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. But stripes, called chevrons(人字形), painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.
Now the American Automobile Association Foundation(基金会) for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.
Excessive (too great) speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards (danger) are the greatest curves, exit slopes, traffic circles, and bridges.
Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.
Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.
1. The passage mainly discusses ________.
A. a new way of highway speed control
B. a new pattern for painting highways
C. a new way of training drivers
D. a new type of optical illusion
2. On roads painted with chevrons, drivers tend to feel that ________.
A. they should avoid speed-related hazards
B. they are driving in the wrong lane
C. they should slow down their speed
D. they are coming near to the speed limit
3. The advantage of chevrons over straight, horizontal bars is that the former ________.
A. can keep drivers awake B. can cut road accidents in half
C. will look more attractive D. will have a longer effect on drivers
4. The American Automobile Association Foundation for Traffic Safety plans to ________.
A. try out the Japanese method in certain areas
B. change the road signs across the country
C. replace straight, horizontal bars with chevrons
D. repeat the Japanese road patterns
5. What does the author say about straight, horizontal bars painted across roads?
A. They are suitable only on broad roads.
B. They are falling out of use in the United States.
C. They are ignored in a long period of time.
D. They cannot be used successfully to traffic circles.
Suppose we built a robot to explore the planet Mars. We provide the robot with seeing detectors(探测器) to keep it away from danger. It is powered entirely by the sun. Should we program the robot to be equally active at all times? No, the robot would be using up energy at a time when it was not receiving any. So we would probably program it to stop its activity at night and to wake up at dawn the next morning.
According to evolutionary(进化的) theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason. The theory does not deny that sleep provides some important restorative functions. It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous. However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us. So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent.
The evolutionary theory explain the differences in sleep among creatures. Why do cats, for instance, sleep so much, while horses sleep so little? Surely cats do not need five times as much repair and restoration as horses do. But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep. Horses must spend almost all their waking hours eating, because what they eat is very low in energy value. Moreover, they cannot afford to sleep too long or too deeply, because their survival depends on their ability to run away from attackers.

D. The sleeping pattern of a living creature is determined by the food it eats.
Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks—we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta. Georgia. People in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.
1. Ray Birdwhistell believes that physical appearance _______.
A. has little to do with culture

A. how much he or she laughs B. how he or she raises his or her eyebrows
C. what he or she likes best D. the way he or she talks
4. This passage might have been taken out of a book dealing with ________.

Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.
This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.
Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn’t disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.
Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.
After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.
It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.
It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.
1. How does the grass water spider kill its prey?
A. in a web B. by drowning C. by poisoning D. with its antennae
2. the writer describes the special spider as “special” because _______.
A. it walks on water B. it has eight eyes
C. of its hairy appearance D. of the way it produces its young
3. The passage tells us that the spider ______.
A. feeds grass and thistles to its young.
B. lives on blades of grass under the water
C. lives in the grass on the banks of streams
D. eats a meal once every five weeks
4. The purpose of the passage is to _______.
A. convince readers that spiders are dangerous
B. indicate that the grass water spider is endangered
C. list all of the spiders that can be found in New Zealand
D. describe the characteristics of the grass water spider
Space travel is definitely bad for astronauts’ bones, reducing their bone density(密度) after only a month of weightlessness, according to French research published on Friday.
Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights.
“Bone loss was especially striking in four astronauts, ” the scientists reported in the Lancet Medical Journal.
They measured the bone mineral density (BMD) of bones in the forearm(前臂) and lower leg of the astronauts who had spent one to six months in space.
The BMD loss was significant in the tibia(胫骨) of the lower leg, a weight-bearing bone, but barely changed in the radius(桡骨) of the forearm. “Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton (骨架) are similarly affected by space conditions, ” they added.
Without gravity the body isn’t bearing any weight so there is no need for calcium (钙) which makes bones strong, and it becomes empty into the bloodstream.
The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.
1. French scientists did their research on Russian astronauts, because _______.
A. they only cared for the Russian astronauts
B. they were not interested in their own astronauts
C. the Russian government invited them to do their research
D. the Russian astronauts worked in space for a long time
2. Scientists have found that _______.
A. the BMD loss may cause serious illness to astronauts
B. the BMD loss may cause some change in astronauts’ bodies
C. astronauts shouldn’t care about the BMD loss
D. astronauts should take some calcium before space travel
3. What cause the BMD loss to astronauts, according to this passage?
A. The food they eat in space. B. The drinks they take in space.
C. The temperature in space. D. The gravity in space.
4. In the third paragraph, the word “striking” means ______.
A. unusual B. simple C. weak D. slow
