The food we eat seems to have a great effect on our health．Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat．Some research has shown tha
t perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well．That food is related to illness is not a new discovery．In 1945,some researchers realized that things commonly used to keep colors in meats and other food additives caused cancer．Yet, these additives remain in our food, and it is difficult to know which things on the wrappings of foods are helpful or harmful．The additives which we eat are not all so direct．Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows．Sometimes similar things are supplied to animals not for their health, but just to make a profit．
The farmers are simply trying to fatten the animals in order to get a higher price on the market．Although some countries have tried to control such things, the practice continues．According to this passage, we can know ．

Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因）is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument，in terms of morality or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations. Then the other clone would be as well. The latter could foe inserted in the woman and allowed to ripen to term. Moreover，cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single(or more) organ(s）.It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle”of life. There would be a large number of same genes., which reduce the chances of improvement，and, in turn, development-the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappea. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as “objects” rather than people in the society.Scientists haven’t 100 percent. guaranteed that the first cloned will be normal. Thus this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades: of it. I believe that cloning is only legal if its purpose is for cloning organs, not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.Which of the following is true according to the passage？
| A．Genetic limitation will be beneficial for some women |
| B．A large number of genes will prevent us from developing |
| C．Prohibition of cloning might limit the freedom of scientists |
| D．First cloned humans might be normal according to scientists |
What’s the author’s opinion on cloning?
| A．Cloning should be entirely banned |
| B．Cloning should be used in creating life |
| C．Cloning will take away the right to reproduce |
| D．Cloning is acceptable if it is used for cloning organs |

Which of the following shows the structure of the passage
He’s out there somewhere, an instant icon in the records of American conflict, the final big-game hunter. But a puzzle, too, his identity would be kept a secret for now, and maybe forever.
He is the unknown shooter. The nameless, faceless triggerman who put a bullet in the head of the world’s most notorious（臭名昭著的）terrorist, Bin Laden.
He’s likely between the ages of 26 and 33, says Marcinko, founder of the “SEALs Team 6” that many believe led the attack on Bin Laden in Abbottabad, Pakistan. He’ll be old enough to have had time to hurdle the extra training tests required to join the counter-terrorism unit, yet young enough to stand the body-punishing harshness of the job. The shooter’s a man, it’s safe to say, because there are no women in the SEALs. And there’s a good chance he’s white, though the SEALs have stepped up efforts to increase the number of minorities in their ranks, Marcinko and Smith say.
He was probably a high school or college athlete, Smith says, a physical specimen who combines strength, speed and wisdom. “They call themselves ‘tactical athletes,’” says Smith, who works with many future SEALs in his Heroes of Tomorrow training program in Severna Park. “It’s getting very scientific.”
Marcinko puts it in more conventional terms: “He’ll be ripped,” says the author of the best-selling autobiography “Rogue Warrior.” “He’s got a lot of upper-body strength. Long arms. Thin waist. Flat stomach.”
On this point, Greitens departs a bit. “You can’t make a lot of physical assumptions,” says the author of “The Heart and the Fist: The Education of a Humanitarian, the Making of a Navy SEAL.” There are SEALs who are 5 feet 4 and SEALs who are 6 feet 5, Greitens says. In his training group, he adds, there were college football boys who couldn’t hack it; those who survived were most often men in good shape, but they also had a willingness to show their concerns in favor of the mission.
The shooter’s probably not the crew-cut（平头）, neatly shaven ideal we’ve come to expect from American fighting forces. “He’s bearded, rough-looking, like a street naughty boy,” Marcinko supposes. “You don’t want to stick out.” Marcinko calls it “modified grooming standards.”
His hands will be calloused（长老茧）, Smith says, or just rough enough,” as Marcinko puts it. And “he’s got frag in him somewhere,” Marcinko says, using the battlefield shorthand for “fragments” of bullets or explosive devices. This will not have been the shooter’s first adventure. Marcinko estimates that he might have made a dozen or more deployments（部署）, tours when he was likely to have dealt with quite a number of dangerous situations, getting ready any time for explosive devices or bullets.Which of the following is most likely to be the title of the passage?
| A．Who shot Bin Laden? | B．What do the SEALS do? |
| C．How can boys be SEALS? | D．What SEALS are like? |
We can say for sure according to the passage that ___________.
| A．the shooter will eventually be revealed in the Press |
| B．the writer is a person who is curious about the shooter |
| C．the writer is a detective who tries to arrest the shooter |
| D．the shooter is a strong man with a pair of rough hands |
Which of the following are the names of writers mentioned in the passage?
①. Marcinko ②. Greitens ③. Smith ④. Abbottabad
| A．①④ | B．③④ | C．②③ | D．①② |

There are various ways in which individual economic units can interact with one another. Three basic ways may be described as the market system, the administered system, and the traditional system.
In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, real goods such as automobiles, shoes, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. Hence, the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy, goods and services are bought or sold for money.
An alternative to the market system is administrative control by some agency over all transactions. This agency will issue commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy.
In a traditional society, production and consumption patterns are governed by tradition; every person’s place within the economic system is fixed by parentage, religion, and custom. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste（阶级） may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. An inactive society may result.What is the main purpose of the passage?
| A．To outline contrasting types of economic systems. |
| B．To explain the science of economics. |
| C．To argue for the superiority of one economic system. |
| D．To compare barter and money-exchange markets. |
In the second paragraph, the underlined word “real” could best be replaced by _______.
| A．valuable | B．concrete | C．absolute | D．reliable |
According to the passage, a barter economy can generate ______.
| A．rapid speed of transactions | B．misunderstandings |
| C．inflation | D．difficulties for the traders |
According to the passage, who has the greatest degree of control in the administered system?
| A．Individual households. | B．Small businesses. |
| C．Major corporations. | D．The government. |
Which of the following is not mentioned by the author as a criterion（标准）for determining a person’s position in a traditional society?
| A．Family background | B．Age |
| C．Religious beliefs. | D．Custom |
The government-run command post in Tunis is staffed around the clock by military personnel, meteorologists and civilians. On the wall are maps, crisscrossed with brightly colors arrows that painstakingly track the fearsome path of the enemy.
What kind of invader gives rise to such high-level monitoring? Not man, not beast, but the lowly desert locust(蝗虫). In recent months, billions of the 3-inch-long winged warriors have descended on Algeria, Libya, Morocco and Tunisia, blackening the sky and eating up crops and vegetation. The insect invasion, the worst in 30 years, is already creating great destruction in the Middle East and is now treating southern Europe. The current crisis began in late 1985 near the Red Sea. Unusually rainy weather moistened the sands of the Sudan, making them ideal seedbed for the locust, which lays its eggs in the earth. The insect onslaught threatens to create yet another African famine. Each locust can eat its weight (not quite a tenth of an ounce) in vegetation every 24 hours. A good-size swarm of 50 billion insects eats up 100,000 tons of grass, trees and crops in a single night.
All ﹩150 million may be needed this year. The U.S. has provided two spraying planes and about 50,000 gal. of pesticide. The European Community has donated ﹩3.8 million in aid and the Soviet Union, Canada, Japan and China have provided chemical-spraying aircraft to help wipe out the pests. But relief efforts are hampered by the relative mildness of approved pesticides, which quickly lose their deadly punch and require frequent replications. The most effective locust killer dieldrin has been linked to cancer and is banned by many Western countries and some of the affected African nations. More than 5 million acres have been dusted with locust-killing chemicals; another 5 million will be treated by the end of June.
On May 30, representatives of Tunisia, Algeria, Libya, Morocco and Mauritania will meet in Algiers to discuss tactics to wipe out the ravenous swarms. The move is an important step, but whatever plan is devised, the locust plague promised to get worse before the insects can be brought under control.The main idea of the first sentence in the passage is that ______.
| A．the command post is stationed with people all the time. |
| B．the command post is crowded with people all the time. |
| C．there are clocks around the command post. |
| D．the clock in the command post is taken care of by the staff. |
The favorable breeding ground for the locust is ______.
| A．rich soil. | B．wet land |
| C．paces covered crops and vegetation | D．the Red Sea |
People are alert at the threat of the locust because ______.
| A．the insects are likely to create another African famine. |
| B．the insects may blacken the sky. |
| C．the number of the insects increases drastically. |
| D．the insects are gathering and moving in great speed. |
Which of the following is true?
| A．Once the pesticides are used, locust will die immediately. |
| B．Relief efforts are proved most fruitful due to the effectiveness of certain pesticides. |
| C．Dieldrin, the most effective locust killer, has been widely accepted in many countries. |
| D．Over 10 million acres of affected area will have been treated with locust-killing chemicals by the end of June. |
The purpose for affected nations to meet in Algiers on May 30 is ______.
| A．to devise anti-locust plans. |
| B．to wipe out the swarms in two years. |
| C．to call out for additional financial aid from other nations. |
| D．to bring the insects under control before the plague gets worse. |
