Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It's a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century.
But nearly all scientists now agree the 10 percent theory is completely unfounded. In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes.
Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o' the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don't affect other essential areas.
From an evolutionary point of view, it's highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 10 percent theory.

A popular student in her small high school, Katie started college expecting to do well in her courses and be best friends with her roommates. But things didn’t turn out that way. Psych 101, the course she thought would be a first-semester favorite, turned out to be a struggle. And her roommates were as different from Katie as the student restaurant’s mystery meat was from her mom’s roasted pork.
Living away from home tends to be the toughest adjustment for first-year students. You may feel homesick in your first weeks or months. It can help to call, write, or email your parents and friends making them know how you’re doing. You can also talk with your roommates. As first-year students themselves, they’re probably experiencing many of the same fears and worries that you’re dealing with.
But what if you don’t get along well with your roommates?
In some cases, it can be a good thing if you and your roommates aren’t much alike. Different views on things may be helpful, so respect your differences no matter what.
If you and your roommates don’t get along well, it can help to find someone who you feel does understand you, which should be easy on a campus with so many people. Many schools have student organization nights where all of the campus clubs gather and promote their organizations, so you can meet people with the same interests there as you. You’ll also meet tons of people in class or in your dorm building.
As homesickness, painful throats, sprained (扭伤的) ankles and wisdom teeth that act up are common among college students, you should check out your student guidebook or your school’s website to find out information about the university health center.
If you think you cannot deal with your problems, make a stop at the school counseling (咨询) center. First-year troubles are something the counselors know well. You can get help there.
From Paragraph 1 we can infer that ____.
A. Katie had been worried about the changes before starting her college life
B. Katie felt satisfied when her college life started
C. Katie wasn’t used to the new environment in college at first
D. Katie has fallen behind in her study after the first semester in college

Which of the following ways of dealing with roommates is RIGHT?

Americans have a reputation for being global illiterate（文盲）, only one in ten can speak another language .That does not stop millions of American tourists ,businessmen, diplomats and journalists from visiting and working in nearly every country in the world. Americans simply expect everyone else to know their language. Few Americans study foreign language extensively and few American schools and universities ask them to. “We want to learn about the people outside
The American preference for English is hardly discouraged in the nation’s schools. At least 20 percent of the country’s high schools teach no foreign language at all. Few schools teach languages to students under 12, when they can best learn another language .As a result ,fewer than 3 percent of all high school graduates achieve “ meaningful” competence in a foreign language . But that is no bar to getting into the nation’s colleges ;only 8 percent have a foreign language requirement. Some colleges permit students to take proficiency（精通）exams to demonstrate they can speak a foreign language―to some degree―instead of taking a language course. Harvard even allows undergraduates to “psych out” of its one year foreign language requirement. Students can persuade health-clinic psychiatrists（精神病医师）to prove their psychological inability to learn another language.
Still ,there are many students who want to learn foreign languages. Some study Spanish to understand the country’s growing Hispanic（西班牙的）population; others want to study the language of their immigrant ancestors .Another reason to learn a foreign language is the tight job market. If you have two qualified people applying for a job at an international firm and only one speaks a foreign language ,it’s obvious who will be chosen.
Questions:
73．Find in the passage a word closest in meaning to the underlined word “competence”.
74．Who is responsible for American students’ incompetence in foreign languages?（回答词数不超过5个）
75．How can Harvard students be allowed to go without the one year foreign language requirement?（回答词数不超过10个）
