For several years, scientists have been testing a substance called interferon(干扰素), a possible wonder drug that is proving to be effective in treating a variety of diseases, including virus infections, bacterial infections, and cancers. To date, the new drug has no side effect of great influence to discourage its use.  But in spite of its success, last year only one gram was produced in the entire world.

The reason for the shortage lies in the structure of interferon. A special protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so effective that the amount given to each patient each time is very small.

Unlike antibiotics (抗生素), interferon does not attack germs directly. Instead, it protects healthy cells from being infected, and prevents the reproduction of viruses within cells.

As you might conclude, one of the most special uses of interferon has been in the treatment of cancer. Dr. Hans Strander, a research physician at Sweden’s famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who had received operations for advanced cancer, half were given  traditional treatments and the other half were given interferon. Among those treated with interferon 70 percent of them remained alive over three years, as compared with only 10 to 30 percent among those who had received the traditional treatments.

In the United States, a large-scale project supported by the American Cancer Society is now under way. If the experiment were successful, interferon could become one of the greatest medical discoveries of our time.

1.What is the difference between antibiotics and interferon?

A. Interferon has serious side effects, while antibiotics do not.

B. Antibiotics kill germs by attacking them directly, while interferon does not.

C. Antibiotics are very effective, while the effect of interferon is limited.

D. They are different in structure, although they are both proteins.

2. According to the passage, if 170 cancer patients received interferon treatment, how many of them would remain alive over three years?

A. About 30.

B. About 50.

C. About 120.

D. About 70.

3. The passage tells us that ________.

A. it is difficult to produce interferon in large quantities because of its special structure.

B. interferon is produced widely in lots of countries.

C. few of the patients who had received traditional treatments remained alive.

D. most of the patients who received interferon also needed traditional treatments.

Wild

I was 16 when my father finally decided he would send me to wilderness camp for several months. He had threatened to do it many times before, but my mother had always managed to prevent him from doing so. This time he insisted on doing it.

The latest incident was the last straw. Impulsively(冲动地), I hade pushed Mr. Ford, my math teacher, down a flight of steps at school. He broke his arm in two places. Anyway, he had agreed not to accuse me as a favour to my dad, who was in the middle of a tight race for sheriff(执法官) in our town. But my reckless behaviour had my dad’s closest advisor talking.

“John, he’s your son and he’s a kid, but he is dragging you down,” I heard Jake Hutch tell my dad through his closed office door the night after I pushed Mr. Ford. “If you can’t make your son obey the rules, how can you make the law obeyed in this town?”

So, off to Pisgah National Forest I went. I imagined hours of untold abuse at the hands of some strong sergeants(警官). I was determined no to be broken. I was who I was.

Nearly every day for six months, a small group of other troubled teens and I carried our 30-pound backpacks on a difficult journey covering about 10 miles. We hiked in a rough wilderness that seemed untouched by civilization.

Our sergeants were firm but kind, not frightening as I had imagined. We learned how to make a fire without matches and create a shelter with branches and grass. We learned which plants were safe to eat out in the wild. I felt myself change. I was calm and often reflective. My old, impulsive self was gone.

One morning, six months later, my dad came to pick me up. I ran to hug him and saw relief and love in his eyes.

“So what’s it like being sheriff?” I asked on the ride home.

“I lost the race, Danny,” he said.

“I’m sorry, Dad.” I knew my behaviour probably had a lot to do with hid defeat.

Dad squeezed my shoulder and brought me close. “As long as I don’t ever lose you, I’m okay.”

1.The author was finally sent to wilderness because _____.

A. he could learn how to survive in the wild

B. his teacher insisted on giving him a lesson

C. he pushed his math teacher down the stairs

D. his mother feared that he would be accused

2.The underlined word “reckless” in Paragraph 2 probably means ______.

A. selfish　　 B. careless　　 C. rude　　 D. reasonable

3.What can we learn about the author from the passage?

A. He changed a lot after the camp.

B. He was not satisfied with his life in the camp.

C. He was still what he used to be after the camp.

D. He made enemies with other troubled teen at the camp.

4.How did the author’s father feel at the end of the story?

A. Grateful.　　 B. Annoyed.

C. Disappointed　 D. Relieved

高三英语阅读理解中等难度题查看答案及解析

Several years ago, I had to replace a receptionist for my unit. Before I advertised for the position, I was approached by another manager, and asked if l would consider a transfer from his staff instead of opening a new competition. My natural question was to ask who he wanted me to consider and why.

It appeared from his description of this employee, Maria, that she was having a lot of problems performing her duties, and had difficulties with her boss, and did not appear to respond to any attempts he, the manager, had made to settle the issues. Now, after listening to his explanation, I really had severe doubts. What crossed my mind, after this discussion, was that he wanted me to take a problem off his hands.

I told him I would think about it and would let him know the next day. As promised, after thinking more about this potential performance issue, I decided that I would agree to speak with Maria privately before I made any decision.

And, what I found out during this interview, left me deep in thought. As it turned out, the    performance issue appeared to result from working for a boss who never extended a good morning greeting, never gave a word of encouragement, and was constantly changing the work load and routines. The end result was a totally ruined employee who was unconfident, hated to see a new work day start.

I decided to accept her transfer to my unit. What started out as a shy, withdrawn and frightened employee turned out to be one of the most productive and loyal employee that I had ever worked with. Maria couldn't do enough and was constantly asking for more and for more responsibility. I was more than happy to give her what she needed-praise for work well done, respect as a person, and encouragement for doing well in anything she dealt with.

Sometimes, we are guilty of holding others back from accomplishing or doing or developing as they should or could. It may be a wise idea that we all look in the mirror, from time to time, to see what we are really like.

1.What can we learn about the writer from the first paragraph?

A. He is a manager in the company.

B. He doesn't like his receptionist.

C. He likes to compete with others.

D. He wants to find another position.

2.After hearing his colleague's description of Maria, the writer thought that Maria_______.

A. attempted to settle the issues

B. was a problem to her boss

C. shouldn't stay in the company

D. could get on well with others

3.Why did Maria fail to perform well in her previous job?

A. Her previous job was not suitable for her.

B. She had difficulty responding to her manager.

C. Her boss didn't inspire her working enthusiasm.

D. Her boss showed no trust in her ability.

4.The writer accepted Maria's transfer to unit probably because he thought that________.

A. she was a ruined employee

B. she would need his protection

C. she would turn out to be a good employee

D. she was a shy and frightened employee

5.The writer probably believes that a good boss should________.

A. praise and award his employees a lot

B. respect, praise and encourage his employees

C. greet his employees and give them much work

D. always give his employees guidance in working

For several months, Cara has been working up the courage to approach her mom about what she saw on Instagram. Not long ago, the 11-year-old girl discovered that her mom had been posting her photos for much of her life. “I’ve wanted to bring it up. It’s strange to see myself up there, and sometimes there are pictures I don’t like of myself,” she said.

Like most other modern kids, Cara grew up under the influence of social media. Facebook, Twiter and YouTube were all founded before she was born. Instagram has been around since she was a toddler (学步儿童). While many kids may not yet have accounts themselves, their parents, schools, sports teams have been organizing an online presence for them since birth. It is a shock to know that details about their lives have been shared online without their permission or knowledge. And this has become a common experience for many teenagers.

Recently a parenting blogger (博主)said that despite her 14-year-old daughter’s horror at discovering that her mother had shared years of highly personal stories and information about her online, she simply could not stop doing it.

But it’s not just crazy mommy bloggers who share their children’s information on social media. Plenty of average parents do the same. There’s even a special word for it: sharenting (晒娃). Almost a quarter of children begin their digital lives when parents upload their prenatal sonogram scans (产前超声波扫描) to the Internet, according to a study conducted by the Internet-security firm AVG. The study also found that 92 percent of kids under the age of 2 already have their own unique digital identity.

1.How does Cara feel about her mom’s behavior?

A.It’s supportive. B.It’s appropriate.

C.It’s annoying. D.It’s favorable.

2.Who is most likely to share children’s information?

A.A quarter of students. B.Some crazy doctors.

C.Kids under the age of 2. D.Many ordinary parents.

3.What can we learn from Paragraph 4?

A.Fathers don’t like to share their kids’ information on social media.

B.25% of children begin their digital lives before they are born.

C.The word “sharenting” can be found 10 years ago.

D.AVG is the name of an internet company.

4.What can be a suitable title for the article?

A.Growing up on the Internet B.A New Term Born
