In order to arrest a person, the police have to be reasonably sure that a crime has been committed. The police must give the suspect the reasons why they are arresting him and tell him his rights under the law. Then the police take the suspect to the police station to "book" him. "Booking" means that the name of the person and the charges against him are formally listed at the police station.
The next step is for the suspect to go before a judge. The judge decides whether the suspect should be kept in jail or released. If the suspect has no previous criminal record and the judge feels that he will return to court rather than run away — for example, because he owns a house and has a family — he can go free. Otherwise, the suspect must put up bail. At this time, too, the judge will appoint a court layer to defend the suspect if he can't afford one.
The suspect returns to court a week or two later. A lawyer from the district attorney's office presents a case against the suspect. This is called a hearing. The attorney may present evidence as well as witnesses. The judge at the hearing then decides whether there is enough reason to hold a trial. If the judge decides that there is sufficient evidence to call for a trial, he or she sets a date for the suspect to appear in court to formally plead guilty or not guilty.
At the trial, a jury of 12 people listens to the evidence from both attorneys and hears the testimony of the witnesses. Then the jury goes into a private room to consider the evidence and decide whether the defendant is guilty of the crime. If the jury decides that the defendant is innocent, he goes free. However, if he is convicted, the judge sets a dale for the defendant to appear in court again for sentencing. At this time, the judge tells the convicted person what his punishment will be. The judge may sentence him to prison, order him to pay a fine, or place him on probation.

Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.
In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.
The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.
This passage mainly talks about ______.
A．the origin of the earth
B．the origin of the ocean
C．the history of the earth
D．the forming of the earth's crust
Passage Three
Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form. a crust of rock that was many miles thick.

It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣专) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding and sometimes safer forms of exercise, such as walking and swimming, running remain the most popular forms of exercise.
As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (强有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times of more a week will produce considerable improvements in physical health in about three months.
According to the passage, what was the percentage of American adults doing regular physical exercises two years ago？ ()
A．About 70%.
B．Nearly 60%.
C．Almost 50%.
D．More than 12%.

NASA, the U.S. space agency, believes there's a good chance that we're not alone in the universe. Last fall, NASA began a new project called the High Resolution Microwave Survey (HRMS). Its aim: to find evidence of life in one of the billions of galaxies in the universe.
The search for intelligent life on other planets isn't new. It began almost 100 years ago. That's when scientists built a huge transmitter to send radio waves into space. Scientists thought smart beings on other planets might pick up the signals.
Scientists also have sent a message about humans and our solar system to a nearby constellation (星座 ). But because the constellation is 25,000 light years away, a return message wouldn't reach Earth for 50,000 years! So don't wait up for an answer.
So far, no extraterrestrial (地球外的 ) beings that we know of have returned our “ calls. ” But according to Dr. Jill Tarter, an HRMS scientist, we haven't exactly had our ears wide open. “ Now, however, ” says Dr. Tarter, “ we've built the tools we need to listen well.”
Last October, Dr. Tarter switched on the largest radio receiver in the world. It's an enormous metal bowl stretching 1,000 feet across a valley in Puerto Rico.
Meanwhile, another NASA scientist turned on a huge radio receiver in California's Mojave Desert. NASA hopes these big dishes-and others around the world-will pick up radio signals from new world.
Dr. Frank Drake has been searching for life in outer space for years. He explains the HRMS project this way: To listen to your radio, you move the tuner on the dial until the channels come in loud and clear: Now imagine radio receivers that scan our galaxy “listening” to 14 million channels every second. That's what NASA's radio receivers in Puerto Rico and California are doing.
But that's not all. Powerful computers hooked to the receivers examine every signal carefully. The computers try to match the signals to ones that scientists already recognize, such as human-made signals. If they can't, Drake and Tarter check on them. “It could prove there is radio technology elsewhere in the universe, ” says Dr. Tarter. “ And that would mean we're not alone. ” 26、NASA scientists started a new project in order to _______.
A、discover life in other galaxies
B、send human beings into space
C、find evidence of a new galaxy
D、confirm the number of galaxies
27、According to Dr.Jill Tarter ,the reason why we haven't received any return any return messages from outer space is that_______.
A、our ears are not sharp enough to hear them
B、our equipment hasn't been good enough
C、it takes millions of yuars for them to reach us
D、it takes quite a long time to send them
28、Dr.Jill Tarter compares the large receiver to _______.
A、the human ear
B、the universe
C、a metal bowl
D、a huge dish
29、According to Dr.Frank Drake ,NASA's radio receivers in Puerto Rico and California are _______.
A、trying to check on every channel carefully
B、moving the tuner on the dial for clear channels
C、scanning the universe for possible signals
D、picking up radio signals from new world
30、The best title of this passage is ________.
A、Signals from the Space
B、The Invention of New Radio Receivers
C、The Intelligent Life in Outer Space
D、NASA Listens for Space Neighbors
More than one in ten people who are regularly exposed to organophosphate pesticides(有机磷酸脂农药) will suffer unrecoverable physical and mental damage, a team of psychiatrists warns. The investigators say that theirs is the first serious attempt to estimate the number of people suffering because of chronic low-level exposure to the pesticides.
"This is a worrying high level of illness," says one researcher. The findings by the researcher, who also treats many of the victims, conflict with those of the Britain's government agency monitoring occupational health, which says there is no good evidence to suggest chronic exposure leads to widespread illness. The research team sent questionnaires to 400 farmers selected at random from a phone book. Of 179 who replied, 130 reported that they had been exposed to organophosphates. And 21 farmers complained of enough symptoms to be classed as suffering from organophosphate poisoning. Allowing for bias inherent in the survey method, they suggest that around 10 percent of farmers exposed to the pesticides suffer from poisoning.
The researchers also uncovered a consistent pattern of symptoms ranging from extreme tiredness and speech difficulty to suicidal impulses. Again this contrasts with the government agency's view that there is no clear pattern of symptoms for pesticide poisoning, making a diagnosis difficult.
They believe the real figure for poisoning is much higher, once you include cancers and heart disease linked to the pesticide. Last year, British specialists also found evidence of a link between organophosphates and severe bone abnormalities in eight men. One of the researchers, Anthony Lyons of Queen's Medical centre in Nottingham, says preliminary results from a larger follow-up study suggest the extent of bone damage may be worse than they feared.
All those who suffer from organophosphate poisoning complain of becoming "exquisitely sensitive" to any further exposure. This is bad news for any Gulf War veterans sent back to the Middle East. Many scientists and doctors are convinced that Gulf War Syndrome is at least partly caused by organophosphate pesticides, which were sprayed in tents and on clothes to protect troops from biting insects.
A spokesman for Britain's Ministry of Defense says there are no immediate plans to send ground troops to the Gulf. But the US is moving 5,000 troops into the region. Returning troops "would be more vulnerable to poisoning", says one of the leading US authorities on such poisoning.
In which area do the findings of the researchers have confliction with those Britain's Health and Safety Executive(HSE), the government agency monitoring occupational health？ ______.
A．Whether exposure to organophosphate will do any harm to man
B．Whether chronic exposure to organophosphate would lead to widespread illness
C．Whether it is worthwhile to find out the number of people suffering from organophosphate poisoning
D．Whether organophosphate is a good pesticide
Some people seem to lose all their energy and drive, wanting only to sleep. Others react in exactly the opposite way. Becoming so over energized that they can't find enough activity to burn off their excess energy. For instance, one woman said she cleaned out all her closets completely and was ready to go next to start on her neighbor's. Both these extremes, however, eventually, the symptoms may be intense for two or three days, but within 10 to 14 days after quitting, most subside (平静下来). The truth is that after people quit smoking, they have more energy, they generally will need less sleep, and feel better about themselves.
Quitting smoking not only extends the ex-smoker's life. but adds new happiness and meaning to one's current life. Most smokers state that immediately after they quit smoking, they start noticing dramatic differences in their overall health and vitality.
Quitting is beneficial at any age, no matter how long a person has been smoking. The death rate of an ex-smoker decreases after quitting. If the patient quits before a serious disease has developed, his/her body may eventually be able to restore itself almost completely.
Which of the following is the main psychological symptom of smokers who quit？ ______.
A．Being light-headed
B．Being anxious
C．Being easily annoyed
D．Being violet
