The difference between substance abuse and addiction is very slight. Substance abuse means using an illegal substance or using a legal substance in the wrong way.1.

You can abuse a drug or alcohol without having an addiction. For example, Sara smoked a few times doesn’t mean that she has an addiction, but it does mean the she’s abusing a drug—and that could lead to an addiction.

2. When we think of addiction, we usually think of alcohol or illegal drugs. But people become addicted to medications, cigarettes and so on! And some substances are more addictive than others. Drugs like heroin are so addictive that they might only be used once or twice before the user loses control.

Addiction means a person has no control over whether he or she uses a drug or drinks. Someone who’s addicted to cocaine has grown so used to the drug that he or she has to have it. 3.

Being physically addicted means a person’s body actually becomes dependent on a particular substance. Someone who is physically addicted and stops using a substance may experience withdrawal symptoms. 4. Psychological addiction happens when the desire for a drug are psychological or emotional. People psychologically addicted feel overcome by the desire to have a drug. They may lie or steal to get it.

A person crosses the line between abuse and addiction when he or she is no longer trying the drug to have fun or get high, but has come to depend on it. 5. An addicted person—whether it’s a physical or psychological addiction or both — no longer feels like there is a choice in taking a substance.

A. It’s better to avoid using medicine or wine in life.

B. People can get addicted to all sorts of substances.

C. Addiction can be physical, psychological, or both.

D. Addiction begins by using a substance like cocaine.

E. His or her whole life centers on the need for the drug.

F. The addicted people often got into trouble by themselves.

G. Common symptoms of withdrawal are generally feeling awful.

Dad had a green comb (梳子）.He bought it when he married Mum. Every night，he would hand me his comb and say. “Good girl, help Daddy clean it, OK?”

I was pleased to do it. At age five, this dull(无趣的) task brought me such joy. I would excitedly turn the tap (水龙头)on and brush the comb carefully. Satisfied that I'd done a good job. I would happily return the comb to Dad. He would smile affectionately (亲切地）at me and place the comb on his wallet.

Two years later. Dad started his own business, which wasn't doing so well. That was when things started to change. Dad didn't come home as early and as much as he used to. Mum and I became mad with him for placing our family in trouble. With time, an uncomfortable silence grew between us.

After my graduation, Dad's business was getting back on track. On my 28th birthday. Dad came home early. As usual I helped him carry his bags into his study. When I turned to leave, he said," Hey, would you help me clean my comb?” I looked at him a while，then took the comb and headed to the sink.

It hit me then: why, as a child, helping Dad clean his comb was such a pleasure. That routine (习惯) meant Dad was home early to spend the evening with Mum and me. It meant a happy and loving family.

I passed the clean comb back to Dad. He smiled at me and carefully placed his comb on his wallet. But this time, I noticed something different. Dad had aged.

Channel Islands

The two main islands, Jersey and Quernsey, are remarkable in that they present a combination of enjoyment, peace and quiet. Neither island is very big (only ten miles long) and so all parts of these coasts are easily reached from the main centers -- St. Helier and St. Peter Port. In both these towns and particularly in Jersey's St. Helier are the amusements of really big resorts (度假胜地). The nearness of France gives a continental atmosphere; the weather here is far better than that of any other part of England. The other three islands, Jethou, Hern and Sark are small and quiet.

Isles of Scilly

The islands are really small and quiet; the weather is warm but windy. The islands are excellent for those who enjoy exploring small inlets (水湾), creeks (小溪) and bays on foot, or better, in a boat.

Isle of Wight

he island is 24 miles across and therefore quite large. The scenery is good and varied. The resorts are neither overlarge nor showy. The island has the best sunshine record in Britain.

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.

Daniella Wride was brushing her daughter’s long brown hair when she noticed that with each comb, masses of the hair were coming out. That was January 1, 2017. Within 20 days, seven-year-old Gianessa Wride’s hair was completely gone, and her doctor said the hair would never grow back. Gianessa had become one of the 6. 8 million Americans with alopecia, an auto-immune disease that causes hair loss.

Alopecia isn’t painful, but for kids who suffer from it, the severe pain comes from standing out from the crowd. For the most part, the students in Gianessa’s first-grade class in Salem, Utah, were understanding. But the occasional jokes of “Baldy”(秃子) made her feel like an abandoned child. “I didn’t want her to feel that she wasn’t like the other kids,” her mother said.”I tried covering her baldness, but the artificial hair was uncomfortable. “

Then comes the school’s traditional “Crazy Hair Day” in April, a great just-for-fun celebration where all the kids and their parents can express their wild sides a bit. Daniella and Gianessa decided that rather than hide Gianessa’s baldness under the artificial hair, they would celebrate it. Daniella bought scrapbook-sticker (贴纸) jewels and decorated her head with flowered designs and even a deer. “They just fit her personality,” Daniella smiled. “She’s so lovely. “

On the morning of the competition, Gianessa was nervous. Would her friends think it was funny? However, with her mother’s encouragement, she had nothing to fear. Impressive Gianessa was a hit and a winner of the crazy-hair competition. Gianessa is now glad that she dared to go bare. “I was sad at first when I lost all my hair,” she told people. “But now I love being bald. I can do things to my head that other kids can’t. I’m thinking now it might be fun to decorate my head with some colourful butterflies and flowers. “

1.Why was Gianessa different from other kids?
