[不定项选择题]People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco bums, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person′s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy (头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers′ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.
What′s the main idea of this passage?
A.Where did cigarettes come from?
B.The effect of smoking on your body.
C.How to smoke is healthy?
D.Who is the first smoker?

TV Shows and Long Bus Trips Long bus rides are like televisions shows.They have a beginning,a middlle,and an end-with commercials thrown in every three or four minutes.The commercials are unavoidable.They happen whether you want them or not.Every couple of minutes a billboard glides by outside the bus window.“Buy Super Clean Toothpaste.""Drink Good‘n’Wet Root Beer.""Fill up with Pacific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of"You Need It!Buy It Now!" The beginning of the ride is comfortable and somewhat exciting,even if you've traveled that way before.Usually some things have changed-new houses,new buildings,sometimes even a new road.The bus driver has a style of driving and it's fun to try to figure it out the first hour or so.If the driver is particularly reckless or daring,the ride can be as thrilling as a suspense story.Will the driver pass the truck in time?Will the driver move into the right or the left-hand lane?After a while,of course,the excitement dies down.Sleeping for a while helps pass the middle hours of the ride.Food always makes bus rides more interesting.But you've got to be careful of what kind of food you eat.Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning.You know it will soon be over and there’s a kind of expectation and excitement in that.The seat,of course,has become harder as the hours have passed.By now you've sat with your legs crossed,with your hands in your lap,with your hands on the arm rests-even with your hands crossed behind your head.The end comes just at the right time.There are just no more ways to sit.
The writer thinks that the end of the ride is somewhat like the beginning because both are______.
A.exciting
B.comfortable
C.tiring
D.boring

To Have and Have Not
It had been boring hanging about the hotel all afternoon.The road crew were playing a game with dollar notes.Folding them into small planes to see whose would fly the furthest.Having nothing better to do,I joined in and won five,and then took the opportunity to escape with my profit. Despite the evil-looking clouds,I had to get out for a while.
I headed for a shop on the other side of the street. Unlike the others,it didn't have a sign shouting its name and business,and instead of the usual impersonal modern lighting,there was an appealing glow inside.Strangely nothing was displayed in the window.Not put off by this,I went inside.
It took my breath away.I didn't know where to look,where to start. On one wall there hung three hand-stitched American quilts that were in such wonderful condition they might have been newly -made .I came across tin toys and antique furniture,and on the wall in front of me,a 1957 stratocaster guitar,also in excellent condition.A card pushed between the strings said $50.I ran my hand along a long shelf of records,reading their titles.And there was more...
"Can I help you?"She startled me.I hadn't even seen the woman behind the counter come in.The way she looked at me,so directly and with such power. It was a look of such intensity that for a moment I felt as if I were wrapped in some kind of magnetic or electrical field.I found it hard to take and almost turned away.But though it was uncomfortable.I was fascinated by the experi- ence of her looking straight into me,and by the feeling that I was neither a stranger,nor strange, to her.
Besides amusement her expression showed sympathy. It was impossible to tell her age.She reminded me faintly of my grandmother because,although her eyes were friendly.I could see that she was not a woman to fall out with .I spoke at last."I was just looking really",I said,though secretly wondering how much of the stuff I could cram into the bus.
The woman turned away and went at once towards a back room,indicating that I should follow her. But it in no way lived up to the first room.The light made me feel peculiar,too.It came from an oil lamp that was hung from the centre of the ceiling and created huge shadows over eve-rything. There were no rare electric guitars,no old necklaces,no hand-painted boxes with deli-cate flowers.It was also obvious that it must have taken years,decades,to collect so much rub-bish,so many old documents arid papers.
I noticed some old books,whose gold lettering had faded, making their titles impossible to read."they look interesting",I said,with some hesitation."To be able to understand that kind of writing you must first have had a similar experience",she said clearly.She noted the confused look on my face,but didn't add anything.
She reached up for a small book which she handed to me."This is the best book I can give you at the moment",she laughed."If you use it."I opened the book to find it full,or rather empty,with blank white pages,but paid her the few dollars she asked for it,becoming embar-rassed when I realised the notes were still folded into little paper planes.I put the book in my pocket,thanked her and left.
The writer disliked the back room because______.
A.there was hardly anything in it
B.she had ordered him to go there
C.he saw nothing he really liked
D.it was too dark to look around
