12.People laugh and people cry.But it is thought that emotions such as anger,grief or joy,typically make Americans feel uncomfortable and embarrassed.The shedder of tears(落泪者) is likely to apologize,even when a great tragedy was the cause.The observer of tears is likely to do everything possible to put an end to the emotional tears.But judging from recent studies of crying behavior,both those responses to tears are often inappropriate and may even be counterproductive (适得其反).
  Humans are the only animals clearly known to shed emotional tears.Since evolution has given rise to few purposeless physiological responses,it is logical to assume that crying has one or more functions that increase survival.
  Although some observers have suggested that crying is a way to ask for assistance form others (as a crying baby might from its mother),the shedding of tears is hardly necessary to get help.Vo-cal (出声的) cries would have been quite enough,more likely than tears to gain attention.So,it appears that there must be something special about tears themselves.
  Indeed,the new studies suggest that emotional tears may play a direct role in easing stress.University of Minnesota researchers who are studying the chemical composition of tears have recently separated two important chemicals from emotional tears.Both chemicals are found only in tears that are shed in response to emotion.Tears shed because of exposure to cut onion would contain no such substance.
  Other researchers are looking into the usefulness of tears as a means of diagnosing human ills and monitoring drugs.At Tulane University's Teat Analysis Laboratory Dr.Peter Kastl and his colleagues r eport that they can use tears to detect drug abuse,to study the causes of"dry eye"syndrome(综合症) and the effects of eye surgery,and perhaps even to measure exposure to environmental pollutants.
64.What does the phrase"both those responses"in Paragraph 1 refer to?D
A.Crying out of sorrow and shedding tears for happiness.
B.The embarrassment and unpleasant feelings of the observers.
C.Linking illness with crying and finding the chemical composition of tears.
D.The tear shedder's apology and the observer's effort to stop the crying.
65.It is known from the first paragraph thatA.
A.shedding tears gives unpleasant feelings to Americans
B.crying may often result in tragedy
C.crying usually wins sympathy from other people
D.one who sheds tears in public will be blamed
66.From the passage we can infer thatB.
A.it is unnatural for people to shed tears
B.we can reduce our stress by shedding tears
C.shedders of tears can't get help by crying loudly
D.unlike animals,humans can shed tears for survival.

19.College visits are important.Before you commit years of your life and money to a school,be sure you're choosing a place that is a good match for your personality and interests.You can't get the"feel"of a school from any guidebook,so be sure to visit the campus.Below are a few tips for getting the most out of your college visit.
Explore on Your Own
Of course you should take an official campus tour,but be sure to allow time to hang around on your own.The trained tour guides will show you a school's selling points.But the oldest and prettiest buildings don't give you the entire picture of a college.Try to walk the extra mile and get the complete picture of the campus.
Read the Bulletin Boards
When you visit the student center,academic buildings and residence halls,take a few minutes to read the bulletin boards.They provide an easy way to see what's happening on campus.The ads for lectures,clubs and plays can tell you what's going on outside the classrooms.
Eat in the Dining Hall
You can get a good feel for student life by eating in the dining hall.Try to sit with students if you can.Do the students seem happy or stressed?Also,is the food good?Are there rich healthy options?Many admission offices will give prospective students coupons(优惠券) for free meals in the dining hall.
Visit a Class in Your Major
If you know what you want to study,a class visit makes a lot of sense.You'll get to observe other students in your field and see how involved they are in classroom discussion.Try to stay after class for a few minutes and chat with the students to get their impressions of their professors and major.Be sure to call in advance to schedule a classroom visit-most colleges don't allow visitors to drop in on class unannounced.
Talk to Lots of Students
Your campus tour guide has been trained to market the school.Try to talk to students who aren't getting paid to impress you.These important conversations can often provide you with information about college life that isn't part of the admission script.Few university officials will tell you if their students spend all weekend drinking or studying,but a group of random students might.
