Section B

Directions: There are several passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and

D). You should decide on the best choice.

Passage One

Questions 31 to 35 are based on the following passage.

In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn’t any crime to worry about.

Amazingly, these happy times appear still to be with us in the world’s biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up homes without fitting locks to their doors.

SATAN can try out a variety of well-known hacking (黑客的) tricks on an Internet site without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle (闯

入……行窃).

But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder.

So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer.

At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage.

But let’s look on the bright side. Given the lack of locks, the Internet is surely the world’s biggest (almost) crime-free society. Maybe that is because hackers are fundamentally honest. Or that there currently isn’t much to steal. Or because vandalism (恶意破坏) isn’t much fun unless you have a peculiar dislike for someone.

Whatever the reason, let’s enjoy it while we can. But expect it all to change, and security to become the number one issue, when the most influential inhabitants of the Net are selling services they want to be paid for.

Passage Two

Questions 36 to 40 are based on the following passage.

It was the worst tragedy in maritime (航海的) history, six times more deadly than the Titanic. When the German cruise ship Wilhelm Gustloff was hit by torpedoes (鱼雷) fired from a Russian submarine in the final winter of World War II, more than 10,000 people — mostly women, children and old people fleeing the final Red Army push into Nazi Germany — were packed aboard. An ice storm had turned the decks into frozen sheets that sent hundreds of families sliding into the sea as the ship tilted and began to go down. Others desperately tried to put lifeboats down. Some who succeeded fought off those in the water who had the strength to try to claw their way aboard. Most people froze immediately. I’ll never forget the screams," says Christa Ntitzmann, 87, one of the 1,200 survivors. She recalls watching the ship, brightly lit, slipping into its dark grave — and into seeming nothingness, rarely mentioned for more than half a century. …… 此处隐藏：5156字，全部文档内容请下载后查看。喜欢就下载吧 ……
