[不定项选择题]共用题干 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 of this passage would probably favor______.
A.bus drivers who weren's reckless
B.driving alone
C.a television set on the bus
D.no billboards along the road

[单项选择] Vice Vaccines At first glance, vice vaccines look just great. These injections promise to inactivate drugs such as cocaine, heroin and nicotine in the bloodstream before they reach the brain. Without the "hit", people just won’’t come back for more. It’’s true that these vaccines are still being developed, so their full risks and benefits are not yet clear. But all the signs are that for people who are in danger of overdosing, or for addicts who want to get themselves clean but need some help to overcome their craving, the vaccines will be immensely valuable. But like many new technologies, they also bring difficult choices. Will convicted criminals who steal to feed their drug habit be allowed back onto the street if they agree to be vaccinated, for example Could a judge even compel these people to be vaccinated Perhaps the most controversial debate that vice vaccines have raised is whether they should be given routinely to childre

Passage Two
Each semester, Andrew Tom receives a term bill outlining his expenses: tuition, dorm fee, student center fee, recreation fee, resident activity fee, health insurance. If only the rest of his expenses were as easy to quantify.
"It’s like you start out the semester with plenty of money and then $ 20 for dinner out here and $100 at the department store there, it’s gone," said Tom, a Northeastern University third-year student. "And there are so many things you need like toothpaste or laundry detergent (洗涤剂) that you don’t think about until you get here and need it."
From the books lining their shelves to the fashionable clothes filling their closets, college students say the expenses of a college education go well beyond tuition and a dining hall meal plan. Many say they arrive on campus only to be overwhelmed by unexpected costs from sports fees to the actual price of a slice of pizza.
Ba
A. the extremely high prices of daily necessities
B. the school’s overcharging for campus activities
C. the too many expenses the students have to pay
D. the pressure of keeping pace with their peers
