Underwater archaeology(考古)-the study of ships, aircraft and human settlements that have sunk under large bodies of water-is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment. Besides the Swedish ship wreck(残骸），underwater archaeologists have made more exciting discoveries such as the 5000-year-old boats in the Mediterranean Sea.
Underwater archaeology can provide facts abut the past. In ancient ports all over the world are ships sunken in the past 6, 000 years. There are also sunken settlements in seas and lakes telling of people’s way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world"s knowledge of history, but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines(挖掘机）often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.

解析
试题分析：文章主要告诉我们的是考古学重要的一个分支——水下考古以及水下考古的目的，面临的困境等。
小题1:B 推理题。文章用瑞典斯德哥尔摩港口的一艘沉船来引起读者的兴趣，来引起下文。故B正确。
小题2:C 细节题。根据第二段前两行Underwater archaeology(考古)-the study of ships, aircraft and human settlements that have sunk under large bodies of water-is really a product of the last 50 years.说明水下考古的目的是为了研究水下的文物，以此来研究历史。故C正确。

Many people enjoy the freedom in blogging. Some, however, find that putting one’s life online can have a price. The blogs of some students in America were stopped by the government for some time because they posted threatening words to their teachers on their blogs.
A recent study finds that nearly a fifth of teens who surf the Internet have their own blogs. And 38 % of teens say they read other people’s blogs. By comparison, about a tenth of adults have their own blogs and a quarter say they read other people’s online magazines.
With the development of the Internet, more and more people will be attracted by blogging.
In another study, 79% of teens agree that people at their age aren’t careful enough when giving out information about themselves online. Besides, careless blogging can also influence blog readers. When you are angry or unhappy, your blog is the first place you turn to. The words you post then may not be rational which you may regret later. To minimize (使减到最小) the negative influence, change the safety setting and make such posts “personal” so that only you can read them.
As long as you are careful with what you post, blogging is a great means of staying in touch with friends and displaying one’s creative works.
小题1:Blogs are the place where people __________.
| A．go online to have a chat |
| B．go online to enjoy freedom |

| B．American students are limited in blogging |
| C．anyone who gets on the Web has his blog |
| D．people should be careful with what they write |
| A．strange | B．perfect |
| C．helpful | D．reasonable |
| A．the use people make of blogs |
| B．the number of people who have blogs |
| C．advantages and disadvantages of blogs |
| D．the author’s suggestions about blogging |
Why is more and more land becoming desert？Scientists think that people make deserts．People are doing bad things to the earth against the scientists’ wish．
Some places on the earth don’t get much rain. But they still don’t become deserts．This is because some green plants are growing there．Small green plants and grass are very important to dry places．Plants don’t let the sun make the earth even drier． Plants do not let the wind blow the dirt away．When a bit of rain falls，the plants hold the water. Without plants, the land can become desert more easily．
小题1:Deserts ____________ ．
| A．never have any plants or animals in them |
| B．can all be turned into good land before long |
| C．are becoming smaller and smaller |
| D．get very little rain |

| D．scientists know little about the deserts |
| A．they don’t let the sun make the earth even drier |
| B．they don’t let the wind blow the soil away |
| C．they hold water |
| D．All of the above． |
| A．plants can keep dry land from becoming desert |
| B．it is good to get rid of the grass in the deserts |

MONTAGNE: How many things emit radiation?
Dr CARACAPPA: Well, radiation and radioactive material is a part of nature. So everything that’s living has some amount of radiation coming from it—a very small amout. Plus there’s radiation in the ground and the air.
So the extremes are uranium in the soil to bananas?
Yes.
By the way, why do bananas have radiation?
Bananas have a lot of potassium(钾). And a small amount of potassium naturally is called potassium 40, which is radioactive
What’s the difference between radiation that’s harmful and not harmful?
Well, the term radiation can apply to a lot of different things. But the harmful radiation is ionizing(离子)radiation. It has enough energy that it can make chemical changes in material. We could get ionizing radiation from an X-ray, for example. It’s the kind of radiation that causes cancer.
The broader definition of radiation includes a lot of things that we call non-ionizing radiation. That includes everything like radio waves and visible light and your microwave.
So what then is the largest contributor of ionizing radiation?
For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon(氡), which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lying areas of homes like basements.
Would it be fair to say that most people do not need to worry about the danger of being exposed to radiation?
I would say that the everyday exposure to radioation that we meet contributes an extremely tiny risk to our life or to our health compared to all of the other risks that we meet in our day-to-day life.
小题1:We can infer from the first paragraph that radiation is______.
| A．rare | B．powerful | C．dangerous | D．common |
| A．an interview | B．an argument | C．a talk show program | D．a science report |
| A．whether it has a small amount of potassium |
| B．whether it changes chemical in materials. |
| C．whether it has energy to change materials |
| D．whether it is visible in life |
| A．advise on how to protect us from radiation |
| B．analyze what causes radiation in daily life |
| C．warn people of the danger of radiation |
| D．expect people not to fear everyday radiation |

Figures show an ever-increasing crime rate, but it is only too easy to imagine "It will never happen to me". Unfortunately, statistics show that it really can happen to you and, if you live in a large city, you run twice the risk of being a victim.
