Passage fourSome pessimistic experts fleel that the automobile is bound to fall into disuse. They see a day in the not too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the futtire should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion(拥挤). One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable(可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer.The computer will then mortitor all of the car’s movements.The drivet will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer(蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that call be carried by a present-day highway. One significant improvement in the future car will probably be （）.

Passage TwoEach 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.Balancing a job with schoolwork, especially at colleges known for their heavy workloads like Harvard and MIT, can be tough. So can the pressure students often feel to financially keep pace with their friends."When you get dragged along shopping, you’re going to spend money; if you get dragged to a party and everyone wants to take a cab but you’re cheap and want to take a bus. Chances are you"ll end up sharing the fee for the cab," said Tom. "I guess you could say no, but no one wants to be the only one eating in the snack bar while your friends are ont to dinner. "Max Cohen, a biology major at MIT, said he is accustomed to watching fellow students spend $ 40 a night to have dinner delivered or $ 50 during a night out at a bar. During the school’s recent spring break, friends on trips for the week posted away messages that read like a world map—Paris, Rome, Tokyo. "Meanwhile I stay home and work," said Cohen. "I didn’t realize when I came here how much money I would spend or how hard I would have to work to get by."It is a lesson some younger students learn quickly. Others, surrounded by credit card offers, go into debt, or worse, are forced to leave school."A lot of people don’t think twice about how much they spend," said a first-year student at MIT, "and you feel the pressure sometimes to go along with them." The sentence "If only the rest of his expenses were as easy to quantify." (Lines 2 ~ 3, Paragraph 1) implies that （）.
