This aging of the population is driven by two factors. The first is declining birth rates, which means old generations are large 【1】（compare） to younger generations, and so, on average, the population becomes older than before. This is 【2】（especial） true in the US. The second reason is 【3】 people are living longer. A child born in the US today has a very realistic chance of living beyond 100 and needs to plan accordingly.

【答案】

【1】compared

【2】especially

【3】that

【解析】

這是一篇說明文。文章介紹了人口老齡化是由兩個(gè)原因造成的。

【1】考查非謂語動(dòng)詞。句意：首先是出生率的下降，這意味著老一代比年輕一代人口多，因此，平均而言，人口比以前老齡化。賓語從句的謂語的are large，且compare與邏輯主語是old generations之間是被動(dòng)詞關(guān)系，因此此處要用過去分詞形式在句子中做狀語。故填compared。

【2】考查副詞。句意：在美國尤其如此。此處要用副詞修飾形容詞true。故填especially。

【3】考查表語從句的引導(dǎo)詞。句意：第二個(gè)原因是人們的壽命變長了。根據(jù)系動(dòng)詞is可知此處是一個(gè)表語從句，從句people are living longer結(jié)構(gòu)完整，不缺成分，因此要用that引導(dǎo)表語從句。故填that。

【題目】 Back in November 1988, Robert Tappan Morris was a 20-something graduate student at Cornell who wanted to know how big the Internet was- that is, how many computers were connected to it. So he wrote a program that would travel from computer to computer and ask each machine to send a signal back to a control server, which would keep count. That was how the world’s first cyber (網(wǎng)絡(luò)) attack set the stage for modern cyber security challenges.

The program worked well. Morris had known that if it traveled too fast there might be problems, but the limits he built in weren’t enough to keep the program from blocking up large sections of the Internet, both copying itself to new machines and sending those pings (電子脈沖) back, When he realized what was happening, even his messages warning system administrators about the problem couldn’t get through. Large numbers of Internet-connected computers are told to send lots of traffic to one particular address, overloading it with so much activity that either the system shuts down or its network connections are completely blocked. Morris’s program is now known as the “Morris worm”.

Worms and viruses are similar, but different in one key way: A virus needs a command, from a user or a hacker (黑客), to run its program. A worm, by contrast, hits the ground running all on its own. For example. even if you never open your email program, a worm that gets onto your computer might email a copy of itself to everyone in your address book.

In a time when few people were concerned about harmful software and nobody had protective software in his computer, the Morris worm spread quickly. It took 72 hours for researchers at Purdue and Berkeley to stop the worm. It affected tens of thousands of systems, Cleaning up the infection cost hundreds or thousands of dollars for each affected machine.

Morris wasn’t trying to destroy the Internet, but he was sentenced t0 three years of probation (緩刑) and a roughly US $ 10.000 fine. In the late 1990s, though. he became a dot-com millionaire- and is now a professor at MIT.

【1】What is Morris’s intention 1o write the program known now as the “Morris worm”?

A.To test the effect of protective software.

B.To start a harmful attack on the Internet.

C.To see how well a program can work on the Internet.

D.To get the number of the computers connected to the Internet.

【2】What is the second paragraph mainly about?

A.What loss the problem caused.

B.How the problem was dealt with.

C.How the unexpected problem came about.

D.What Morris did to prevent the problem from expanding.

【3】What does the underlined part “hits the ground” in Paragraph 3 mean?

A.Copies itself.B.Gets on the Internet.

C.Gets the user’s command.D.Copies your email address book.

【4】What happened to Morris after the attack?

A.He was punished for it.B.He invented a protective software.

C.He got help from a millionaire.D.He was asked to clear up the Internet.
