【题目】 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 (网络) 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 (电子脉冲) 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 (缓刑) 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.

1What 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.

2What 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.

3What 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.

4What 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.

【题目】 It was back in 2014. I learned I needed an operation to remove the tumor (肿瘤). Hearing the word “cancer” was the first shock, but knowing the surgeon would have to cut the front of my neck open was a lot to swallow. I was relieved to learn that thyroid (甲状腺) cancer can be treated if caught early, but 1 wasn’t thrilled it would mean a lifelong scar front and center on my neck.

Back at home, I looked at my reflection in the mirror. I admired my neck, running my finger across a delicate gold chain I wore. Then came a tiny voice, “Mommy!” My then five year -old son. Jack, appeared in the mirror behind me. Our reflection was a big reality check. See, my son didn’t know I had been diagnosed (诊断) with the Big C, or that I was having an operation. I patiently explained my condition to him and told him I would have a scar on my neck after the operation.

I never had any intentions of hiding the scar. I didn’t want my son to think my scar was something to be ashamed of. I was his role model and I needed to set a good example. Bad things can happen, but it’s how you deal with them that matters.

The operation was successful. The recovery process, bearing it all, in the grocery store, out to dinner with family and on the summer camp pickup line, made me realize, if I could get through this phase (阶段),I could bear the scar of survival forever. The scar proves I looked at fear in the face and won.

People will ask about my scar even though it’s a very thin. dull line five years later. That means I have the chance to educate others about thyroid cancer and how they should. self-check their necks and remind their doctors to do the same, at yearly physicals. To me, the scar is like a superhero stamp.

1What’s the author worried about before the operation?

A.Her neck would look ugly.B.The tumor couldn’t be removed.

C.Jack couldn’t take care of himself.D.She would have difficulty swallowing.

2Why did the author decide to face the reality bravely?

A.She didn’t care how people liked her.

B.She realized she didn’t have other choice.

C.She wanted to set a good example to her son.

D.She felt lucky to have her cancer caught early.

3How does the recovery process turn out?

A.Regretful.B.Stressful.

C.Surprising.D.Meaningful.

4What can be inferred about the author from the last paragraph?

A.She has a better chance of education.

B.She feels proud of what she has done.

C.She has become an expert in cancer treatment.

D.She has suffered [rom poor health for five years.

【题目】 E-cigarettes lead to as many lung diseases as tobacco products, a new study has found. The report from the University of North Carolina at Chapel Hill compared saliva (唾液) samples from tobacco smokers, e-cigarette smokers and nonsmokers. Researchers found that e-cigarette smokers were likely to develop dangerous proteins associated with lung diseases. The study adds to a growing body of evidence proving that e-cigarettes might not be the perfect alternative smokers addicted to tobacco are looking for.

Last year a Surgeon General’s report claimed that the use of e-cigarettes among a certain group of people jumped 900 percent from 2011 to 2015 and more studies were carried out to research their side effects. That same year, the FDA put e-cigarettes in the tobacco products the administration monitors.

Previous research from UCLA has proven that e-cigarettes can cause lifelong damage to one’s heart, and that one puff (吸一口烟) of an e-cigarette is all it takes to increase one’s risk of having a heart attack. For the new study UNC researchers observed 15 e-cigarette users, 14 cigarette smokers and 15 nonsmokers. The study revealed that e-cigarette smokers have raised levels of NET-related proteins in their airways, the increased levels of which can lead to lung illnesses, making it difficult for patients to breathe.

Study author Dr Mehmet Keismer said, “There is confusion about whether e-cigarettes are ‘safer’ than cigarettes because the potential adverse effects of e-cigarettes are only beginning to be studied. Our results suggest that e-cigarettes might be just as bad as cigarettes.” Dr Keismer also stressed that e-cigarettes come with their own harmful risks along with those linked to tobacco, which challenges the concept that switching from cigarettes to e-cigarettes is a healthier alternative.

A citizen named Dyclna said, “The e-cigarettes probably make you cough less, but nobody gives a warning about your lungs. For producers, it’s just a money thing — it’s just about getting profits from it. The problem is that our government just stands there with its hands behind the back.”

1Why did the FDA list e-cigarettes into monitored products?

A.It might realize the harm of them.

B.It wanted to improve their quality.

C.It aimed to reduce their illegal sales.

D.It might be warned by the government.

2What harm does the increased level of NET do to people?

A.Leading to weight gain.B.Spoiling people’s appetite.

C.Making breathing hard.D.Speeding people’s heartbeat.

3What does Dyclna mainly want to express?

A.E-cigarettes are safer than regular ones.

B.E-cigarettes can only benefit few people.

C.Producers make a high profit from e-cigarettes.

D.Governments are to blame for e-cigarettes’ consumption.

4What is the best title for the text?

A.E-cigarettes: A new way of smoking.

B.E-cigarettes: A better way than tobacco?

C.E-cigarettes: The harmful proteins it produces.

D.E-cigarettes: The urgent need of government control.

【题目】 Old Mrs. Lynn was working in the cottage, hanging the washed clothes on the line. What she wasn’t aware was that some children were hiding in a nearby tree watching her every move. They were sure that she was a witch and wanted to find the evidence.

They watched nervously as she took a broomstick to sweep the dirt from her stone steps. But much to their disappointment, she didn’t get on the broomstick and fly off. The old lady only looked up when her hen began to make sounds loudly — signaling that she had laid an egg in the nest on the top of the haystack. (干草堆).

The old lady put aside her broomstick and walked to the haystack, followed by Michael, a black cat she had rescued from a fox trap. With only three legs, it was hard for Michael to keep up with his mistress. The cat was proof for the children that only a witch would own a black cat with three legs! Accidentally, she tripped and crashed to the ground. The children were in horror.

“Should we go and help her?” asked Mia.

“What if it’s a trick?” replied Patrick. “She probably knows we’re here. Witches know things like that!”

After thinking for a while, Julia said, “Anyway, we should go and check whether she is all right.”

Approaching prudently, they could see a wound on the old lady’s forehead. She had knocked her head on a stone and was unconscious.

“Go and get Dad,” Mia yelled to her brothers. “Tell him about the accident.”

Later, in the hospital, the old lady smiled her thanks. “I was so lucky that you lovely children happened to be passing when I fell. I must have yelled quite loudly.” The children exchanged guilty glances, but were very pleased that she was not a witch after all!

1Mrs. Lynn stopped sweeping when ________.

A.her doorstep became very clean

B.she heard the hen making sounds loudly

C.she noticed the children in the tree

D.her cat Michael managed to get her attention

2Why was Patrick not willing to help Mrs. Lynn when she fell?

A.He thought that she could be cheating them.

B.He was afraid of the three-legged black cat.

C.He did not think that she was hurt in the fall.

D.He knew he and the others shouldn’t have been in her tree.

3Which of the definitions is closest in meaning to the underlined word “prudently” ?

A.Slowly.B.Hurriedly.

C.Carefully.D.Quietly.

4What is the main idea of the story?

A.Constant dropping wears away a stone.

B.Never judge a book by its cover.

C.A friend in need is a friend indeed.

D.A good medicine tastes bitter.
