What can explain and solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going—and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.

The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site.
Web sites offering cheap services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they thought they bought.
The thieves then go shopping with your card number--- or sell the information over internet.
Computers hackers（黑客） have broken down security（安全） systems raising questions about the safety of cardholder information. Several months ago, 25,000 customers of CD Universe, and on-line music retailer（批发商）, were not lucky. Their name, addresses and credit-card numbers were posted on a web site after the retailer refused to pay US $157,828 to get back the information.
Credit-card firms are now fighting against on-line fraud. Master-card is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated.
Ask about your credit-firm’s on-line rules. Under British law, cardholders are responsible for the first US $78 of any fraudulent spending.
And shop only at secure sites: Send your credit-card information only if the web site offers advanced secure system. If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The web site address may also start the extra “s” stands for secure.
If you still have any doubt, give your credit-card information over the telephone.
Keep your password safe: Most on-line sites require a user name and password before placing an order. Treat your password with care.

Authoring a blog, maintaining a blog or adding an article to an existing blog is called “blogging”. Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as “text and photos” in a blog can be called “blog posts”, “posts”, or “entries”. The person who posts these entries is called a “blogger”.
Now, somewhere around the world, a blog is created almost every 6 seconds. Because it’s great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He’s trying to make blogs the important tools for future business communications.
小题1:A blog is .
| A．a comment | B．an Internet journal |
| C．a design | D．a link |
| A．talk to others | B．give comments | C．read articles | D．enjoy photos |
| A．A person who posts letters. |
| B．A person who writes articles. |
| C．A person who posts text or photos in a blog. |
| D．A person who is an online publisher. |
| A．give everyone the chance to be an online writer |
| B．can be created by people without much knowledge of computer technology |

| D．all of the above |
Researchers think they may be able to stop AIDS from connecting to T4 ceils．When AIDS virus finds a T4 cell，it actually connects to a part of the cell called CD4 protein．
Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood．This way the AIDS virus will connect to cloned protein instead of the real ones．Scientists use genetic engineering methods to make the clones．Normally a CD4 protein remains on the T4 cell at all times；the AIDS virus must go to it．
In a new technique，however，the cloned CD4 protein is not connected to a cell．It floats freely，so a lot more can be put into the blood to keep the AIDS virus away from real CD4 protein on T4 cells．One report says the．AIDS virus connects to cloned protein just as effectively as it connects to real protein．That report was based on tests with blood cells grown in labs．The technique is just now beginning to be tested in animals．If successful，it may be tested in humans within a year．
小题1:The new technique can .
| A．cure AIDS |
| B．kill the AIDS virus |
| C．prevent the AIDS virus from spreading |
| D．produce new anti-AIDS cells |
| A．itself |
| B．the blood cells |

Probably the greatest deficiency （不足）of the Titanic was that she was built 40 years before the widespread use of the wonderful invention radar(雷达). Her only defense against icebergs and hidden obstacles was to rely on manned lookouts. On that fateful night the eyesight of trained lookouts only provided 37 seconds of warning before the collision.
Traveling at nearly 30 miles an hour the Titanic was moving far too fast to avoid the huge iceberg. The warning did prevent a head-on collision as the officer on the bridge managed to turn the ship slightly.
The last ship to send a warning was the California. She was within ten miles of the Titanic during the disaster, but her radio operator went to bed at midnight and never received any of the SOS messages from the Titanic. That was one of the important lessons learned from the catastrophe, the need for 24-hour radio operators on all passenger liners.
Another lesson learned was the need for more lifeboats. The Titanic remained afloat(漂浮) for almost three hours and most of the passengers could have been saved with enough lifeboats.
1,500 passengers and workers died in the 28 degree waters of the Atlantic. Out of the tragedy, the sinking did produce some important maritime reforms. The winter travel routes were changed to the south and the Coast Guard began to keep an eye on the location of all icebergs. The new rules for lifeboats were obvious to all. There must be enough lifeboats for everybody on board.
The most important lesson learned was that no one would ever again consider a ship unsinkable- no matter how large or how well constructed. Never again would sailors place their faith in a ship above the power of the sea.
小题1:The text mainly tells us ______.
| A．the reason why the Titanic sank in the Atlantic Ocean |
| B．how the unsinkable ship of Titanic sank in the Atlantic Ocean |
| C．the lessons that we could learn from the accident of theTitanic |
| D．the things we should do to protect the lives on the ship |
| A．If the captain had been more careful, he could have had the chance to save the Titanic. |
| B．If radar had existed 40 years ago, the Titanic would have never disappeared from the world. |
| C．If the lookout had had much more experience, he could have had the time to save the Titanic. |
| D．If there had been enough lifeboats on the Titanic, the Titanic would not have sunk in the Atlantic. |
| A．Lessons from the Titanic | B．Technology is Important |
| C．Demands of Passengers | D．Power of Sea |
| A．They think there really exists the unsinkable ship. |
| B．They think ships could eventually defeat the sea. |
| C．They think there is no power that could control the sea. |
| D．They think the bigger the ship is, the safer it is. |
Here’s something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later.
This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. “Don"t be too quick to get help when learning something new,” education expert Manu Kapur told TFK. “Try to work on it yourself even if it means trying different ways.”
Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher’s help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher.
With the teacher’s help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution.
Kapur’s advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. “Simply doing a little work or nothing at all won’t work,” says Kapur. “The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible.”

| B．Let students learn it on themselves in one way. |
| C．Let students learn it by themselves in the same way. |
| D．Let students learn it for themselves in different ways. |
| A．By asking questions. |
| B．By solving art problems. |
| C．By group comparations. |
| D．By solving science problems. |
| A．Getting the teacher’s help. |
| B．Getting the student’s help. |
| C．Grasping the learning course. |
