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. 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.

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______.
