Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for(满足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.
The passage tells us that Charles Darwin .
| A．was a great English scientist |
| B．always liked doing the experiments that others thought difficult |

| D．didn’t get well with others |
The underlined phrase “set aside” most probably means .
| A．throw away | B．store up |
| C．put to use | D．realize |
The author of the passage tries to .
| A．convince us that Charles Darwin, Galileo and Newton are the greatest scientists in the world |
| B．draw the conclusion that basic sciences are simple things |
| C．prove that two sheets of paper, with the same size and shape, will fall at the same speed |
| D．draw our attention to everyday happenings around us |
Which of the following is TRUE?
| A．Darwin really did foolish experiments. |
| B．According to some people Darwin did foolish experiments. |
| C．It is believed by all the people that things could be important though they seemed to be simple. |
| D．Galileo and Newton worked out ancient Greek physics. |
In this voyage I visited my new colony on the island, saw the Spaniards(西班牙人), had the whole story of their lives and of the villains(罪犯) I left there; how at first they treated the poor Spaniards badly,·how they afterwards agreed, disagreed, unired, separated, and how at last the Spaniards were forced to use violence with them; how they gave in to the spaniards, how honestly the Spaniards used them ---- a history, if it were entered into, as full of variety and wonderful
accidents as my own part ---- particularly, also, as to their battles with the Caribbeans, who landed several times upon the Island, and as to the improvement they made upon the Island itself, and how five of them made an attempt upon the main land, and brought away eleven men and five women prisoners, by which, at my coming, I found about twenty young children on the Island.
Here I stayed bout 20 days, left them supplies of all necessary things, and particularly of arms, powder, shot, cloths, tools, and two workmen, which I brought from England with me, namely a carpenter and a smith.
Besides this, I shared the Island into parts with them, reserved to myself the property of whole but gave them such parts resoeetively as they agreed on; and having settled all things with them and encouraged them not to leave the place, I left them there.
From then on I landed the Brazils, from where I sent a bark, which I bought there, with more people to the island; and in it, besides other supplies, I sent seven women, being such persons as I found proper for service, or for wives to such as would take them. As to the Englishmen, I promised them to send them some women from England, with a good cargo(船货) of necessaries, if they would apply themselves to planting ---- which I afterwards could not perform. And the fellows proved very honest and diligent after they were mastered and had their properties set apart for them. I sent them also from the Brazils five cows, three of them being big with calf, some sheep, and some pigs, which when I came again were considerably increased.
But all these things, with an account how 300 Caribbeans came and invaded(入侵) them, and ruined their plantations, and how they fought with that whole number twice, and were at first defeated, and one of them killed; but at last a storm destroying most of their enemies’ boats, they destroyed almost all the rest, and renewed and recovered the possession of their plantation, and still lived upon the Island.
All these things, with some very surprising incidents in some new adventures of my own, for ten years more, I may perhaps give a further account of the story.

It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(证明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic
variations(变异). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子关系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.

Kenya wants to organize a major international conference to discuss how to fight piracy(海盗) off the coast of Somalia. The conference may also deal with ways to rescue Somalia from seventeen years of civil war. More than forty percent of its people depend on food aid.
Kenyan Foreign Minister Moses Wetangula says the world cannot end piracy and civil war without dealing with Somalia’s political problems.
Somali pirates operate in the Indian Ocean and the Gulf of Aden. The Gulf of Aden connects the Red Sea to the Mediterranean by way of the Suez Canal. The pirates have fast boats, modern weapons and equipment like satellite phones and global positioning systems.
Pirates hijacked the Sirius Star off the coast of Kenya and moved it to waters off Somalia.
The tanker Sirius Star, at three hundred thirty meters long, is the biggest ship ever known to have been captured by pirates. It also happened farther south than most attacks, and farther out at sea ---- more than eight hundred kilometers from land.
The ship was headed for the United States with two million karrels of oil, worth an estimated one hundred million dollars. A Saudi Arabian company owns the tanker. The pirates have reportedly demanded twenty-five million dollars in negotiations to release the ship and its crew of twenty-five.
Somali pirates generally do not steal goods or kill hostages. They are believed to be holding seventeen ships with about three hundred crew members. Among the ships is a Ukrainian vessel hijacked(劫持) in September with a load of military weapons including tanks.
The increase in piracy is raising the cost of insuring ships. Also, oil from the Middle East and exports from East Asia could take longer to arrive.
Some of the world’s heaviest shipping traffic passes the Somali coast. But major shipping companies have begun to consider new routes. One of the world’s biggest shippers, A.P, Moeller Maersk, says it will avoid the Gulf of Aden. A move away from the Suez Canal could hurt Egypt’s economy.
American and other foreign navy ships are now watching for pirates. This week the Indian Navy destroyed a heavily armed “mother ship” in the Gulf of Aden. But the area to protect covers more than one hundred sixty million square kilometers.
56. According to the passage, which of the following is the key to solving the piracy in Somalia?
A. Providing lots of money. B. Ending Civil war.
C. Supplying enough food. D. Handling Somalia’s political problems.
57. Somali pirates do the following things except that _______.
A. they demand money B. they hold the ships with crew
C. they kill some of the hostages D. they hijack ships with military weapons
58. What can we infer from the passage?
A. The cost of ship transport is decreasing.
B. The routes of some ships might change.
C. Nothing has been done to fight against the piracy.
D. The Suez Canal is of no importance to Egypt’s economy.
