[单项选择]New Foods and the New World
In the last 500 years, nothing about people—not their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree (可可树) by South American Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Braz

B. they were forced to leave their homeland and move to America
C. the weather conditions in Ireland were not suitable for growing potatoes
D. the potato harvest was bad

第三篇
Up in Smoke
I began to smoke when I was in high school. In fact,I remember the evening I was at a girlfriend's house,and we were watching a movie一a terribly romantic movie.He(the hero of the movie)was in love,she(his lady)was beautiful,and they were both smoking. My friend had only two cigarettes from a pack in her mother's purse,and she gave one to me.It was my first time.
My parents didn't care much. They both smoked,and my older brother did too. My mother told me that smokers don't grow tall,but I was already 5 '6"(taller than most of the boys in my class), so I was happy to hear that"fact".In school,the teachers talked against smoking,but the cigarette advertisements were so exciting. The men in the ads were so good-looking and so successful,and the women were well, they were beautiful and sophisticated（老于世故的）.
I read a book called How to Stop Smoking. The writer said that smoking wastes time,and that cigarettes cost a lot of money."So what?"I thought. The book didn't say that smoking can take away years of your life.But ten years later,everyone began to hear about the negative effects of cigarette smoke:lung disease,cancer,and heart problems.After that,there was a health warning on every pack of cigarettes.I didn't pay much attention to the reports and warnings.I felt healthy,and thought I was taking good care of myself.
Then two events changed my mind.First,I started to cough,I thought it was just a cold,but it.didn't get better. Second,my brother got lung cancer. He got sicker and sicker. My brother and I used to smoke cigarettes together over twenty years ago,and we smoked our last cigarettes together the day before he died,I sat with him in his hospital room,and I decided to quit."NO more cigarettes,ever,"I said to myself.
However,it was very hard to stop.Nicotine（尼古丁）is a drug;as a result,cigarettes cause a powerful addiction.I tried several times to quit on my own一wlthout success.I made excuses,I told myself:Smoking helps me keep my figure一I don,t gain weight when I smoke.Smoking not only relaxes me but it also helps me think clearly.I,m a free,liberated woman,I can smoke when I want to.
Finally,I ran out of excuses一I might say my excuses went up in smoke.I joined the"Stop Smoking"program at the local hospital,which also ended up in failure.
The writer found it hard to quit smoking because______.
A.she had been addicted to nicotine
B.she had been putting on weight
C.she could not think clearly
D.she was an independent woman
