Directions: Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Dolphins are not fish; they’re mammals. They are warm-blooded like man and give birth to one baby called a calf at a time. At birth a calf is about 90—130cm long and grows to about 4m. They live up to 40 years. They are highly sociable animals.
Their teeth are interlocking rows of hooks, suitable for holding slippery fish. They eat fish whole starting with head first. When they go wild they keep their mouth open and sometimes keep it nodding to express their aggression. Greater aggression is shown by violent jaw clapping. Dolphins breathe through their blowhole(呼吸孔) located at the top of their head. The dolphin’s eyes produce a special slippery secretion(分泌物) which protects the eyes from foreign objects and water friction.
Dolphins use their powerful tail to move through the water. They also use their tail while hunting. They slap their tail rapidly when they get annoyed or when they want to indicate the sign of danger to alert other dolphins.
The dolphin’s skin is completely smooth allowing the dolphin to move easily through the water, and also reduce heat loss. Their skin may bear rake marks from other dolphin’s teeth during play or mating, and can easily become badly sunburned if they strand(搁浅).
Their bodies are very streamlined so they may swim at high speed through the water, and an example of this is their ears. Dolphin’s ears are barely noticeable marked only by a small hole just behind the eyes.
While sleeping, it shuts down only half of its brain, as its breathing is under voluntary control. Dolphins take short catnaps, floating just below the surface, and then slowly rising to breathe. Often dolphins are very active during night time, for some this is their main feeding time. Dolphins are able to dive to great depths, and also leap to great heights. They may leap to avoid predators or to show how powerful they are to females at mating time.

Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobiliser (锁止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.
The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro- processor and memory, and a GPS (全球定位系统) satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted.
In the UK, a set of technical fixes is already making life harder for car thieves. 'The pattern of vehicle crime has changed,’ says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old.
Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code beamed out by the ignition (点火) key. In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997.
But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.
If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal.
Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit.
66. What's the function of the remote immobilizer fitted to a car?
A .To allow the car to lock automatically when stolen.
B. To prevent the car thief from restarting it once it stops.
C. To help the police make a surprise attack on the car thief.
D. To prevent car theft by sending a radio signal to the car owner.
67. By saying 'The pattern of vehicle crime has changed' (Lines 1-2. Para. 3). Martyn Randall suggests that ____.
A. self-prepared tools are no longer enough for car theft
B. the thief has to make use of computer technology
C. it takes a longer time for the car thief to do the stealing
D. the thief has lost interest in stealing cars over 10 years old
68. What is essential in making a modern car tougher to steal?
A. A GPS satellite positioning receiver. B. A unique ID card.
C. A special cellphone signal. D. A coded ignition key.
69. Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?
A. To give the driver time to contact the operations centre.
B. To allow for possible errors in the GPS system.
C. To keep police informed of the car's movements.
D. To leave time for the operations centre to give an alarm.
70. What will the operations centre do first after receiving an alarm?
A. Start the tracking system. B. Locate the missing car.
C. Contact the car owner. D. Block the car engine
What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity (容量). As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger.
Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own.
56. The size of man’s forehead will probably grow bigger because _______.
A. he will use his brain more and more as time goes on
B. he makes use only 20% of the brain’s capacity
C. his brain has grown larger over the past centuries
D. the other 80% of his brain will grow in due time
57. What serves as the evidence that man is changing?
A. Man has got stronger eyes now than he ever had.
B. Man has been growing taller over the past 500 years.
C. Man’s hair is getting thinner and thinner.
D. Man’s arms and legs have become lighter and weaker.
58. What will be true about a human being in the future?
A. He will be hairless because hair is no longer useful.
B. He will have smaller eyes and will wear better glasses.
C. His fingers will grow weaker because he won’t have to make use of them.
D. He will think and feel in a different way.
59. It is implied that __________________.
A. human beings will become more attractive in the future
B. body organs will become poorer if they are not used often
C. human beings hope for a change in the future life
D. future life is always predictable
60. The passage mainly tells us that _______________.
A. man’s life will be different in the future B. man is growing taller and uglier as time passes
C. future man will look quite different from us
D. human beings’ organs will function weaker
Directions: Complete the following passage by filling in each blank with ONE word that best fits the context.
New studies show how food and its production affect the globe and its climate. The process of making a hamburger, for example, requires lots of energy. A cow has to be fed and raised on farmland. And cow waste is a major source of methane（沼气）— 48 especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed and shipped, 49 takes fuel. Most of the cow won’t even be used for meat people eat. By the time a hamburger finally lands on a dinner plate, 50 has made bad effect on the environment.
We can reduce the production of global warming gases by eating less beef. Other kinds of meat like pork and chicken do 51 harm to the environment ---at least 52 terms of the amount of greenhouse gases released. 53 , all kinds of meat are harder on the planet than vegetables. 54 changing our diet to less meat and more vegetables, as it turns 55 , may do the world some good.
