Tears are nature"s way of making us feel more comfortable. When our eyes is made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and “red –eyes” from over work and late hours, tears form in our eyes to clean and re-flesh them.
Tears are also a sign of strong emotion. We cry when we are sad and we cry when we are happy.
And tears seem to be uniquely(唯独)human. We know that animals also experience emotion—fear, pleasure, loneliness — but they do not shed (流) tears. From this, we can conclude that tears are closely related to the emotional and biological make up of the human species.
Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland(腺)in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea.
And it is clear that, in addition to(除了) the emotional benefits(好处), the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge(合并)into one and make us even more "human" than we would otherwise be.
68.According to the passage, human beings may have originated(起源于)in________.
A.the sea B.the salt C.chemicals D.animals
69.Which of the following is NOT a function of tears?
A.Biological B.Emotional C.Political D.Chemical
70.According to the article, which of the following is unique to humans?
A.The feeling of loneliness. B.The state of feeling good.
C.The ability to shed tears D.The feeling of fear
71.The underlined word “eliminate” probably means_______.
A.add B.produce C.replace D.remove

Some people think that they will get ill if they use their brains (大脑) too much.. It is not true. Through many studies, scientists show us that the more you use your brains, the better it will be, and the cleverer you will become.
Of course, if you want to keep your mind clear and active, you must take a proper rest and study properly. To the teenagers, using their brains in the morning is good for their health.
There are many ways to rest. One is a peaceful rest. Sleep is a peaceful rest. Another is an active rest. For example, take a walk outdoors, do more exercises every day. To change the way of the brains’ activities is also a good way to rest.
In everyday life, to eat some eggs, meat, fresh vegetables and fruit(水果)is also good for the brains.
Wish you a wise man and a happy life.

Providing small classes for at least several grades starting in early primary school gives students the best chance to succeed in late grades, according to groundbreaking new research from a Michigan State University scholar.
The research by Spyros Konstantopoulos, a professor of education, is the first to examine the effects of class size over a period and for all levels of students. The study appears in the American Journal of Education.
He is also a member of a group for the Department of Education’s Instiute of Education Sciences that will give official advice on class size to the states. He said the advice will mirror his research: the best plan is to provide continuous small classes(13 to 17 students) for at least several years starting in kindergarten or first grade.
“For a logn time states thought they could just do it in kindergarten or first grade for one year and get the benefits,” He said. “I don’t believe that. I think you need at least a few years in a row where all students, and especially low-achievers, receive the treatment, and then you see the benefits later.”
His research used data from the Project Star study in Tennessee that analyzed the effects of class size on more than 11,000 students in primary and middle school. He found that students who had been in small classes from kindergarten through third grade had actually higher test scores in grades four through eight than students who been in larger classes early on.
Students from all achievement levels benefited from small classes, the research found. “But low-achievers benefited the most, which narrowed the achievement gap with high –achievers in science, reading and math, ” he said.
Although the study didn’t consider classroom practices, he said the reason for the narrowing gap is likely due to low-achieving students receiving more attention from teachers.
“This is especially important in poorer schools because teacher effectiveness matters more in schools with more disadvantaged and low-performing students, ” he said.
48.The professor argues about ________ .
A.the size of the class
B.the period of the class
C.the attention from teachers
D.the achievements of students
49.The result of the research shows that _________.
A.small classes for one year in early grade are enough
B.continuous small classes help students achieve more
C.it’s best to attend small classes in kindergarten
D.small classes do equal good to students of all levels
50.What can we infer from the passage?
A.High achievers will not benefit from small classes.
B.Continuous small classes have not been widely accepted.
C.Low-achievers should be separated from high-achievers.
D.Teachers’ attention matters less than classroom practices.
51.The underlined word “This” in the last paragraph refers to _______.
A.the gap between low and high achievers
B.continuous small classes
C.classroom practices in later grades
D.the Project Star Sturdy
Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program and developmental math.
Moreover, the classroom teacher can also play an important role in explaining to parents what they should do. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils’ progress, can significantly aid the interchanged of ideas between school and home.
Suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent change his method. He might be persuaded to let Junior participate in discussing he family budget, buying the food, using a measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in math and at the same time, enjoying the work.
Too often, however, teachers’ conferences with parents are devoted to unimportant accounts of children’s wrongdoing, complaints about laziness and poor work habits, and suggestions for punishments and rewards at home.
What is needed is a more creative approach in which the teacher, as a professional advisor, plants ideas in parents’ minds for the best use of the many hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters’ competence.
小题1:The underlined phrase “keep parents apprised of” (Line 1, Para. 2) probably means to let parents .
A.judge | B.know | C.design | D.develop |
A.To improve the relationship between teacher and parents. |
B.To explain to parents the change of the school curriculum. |
C.To report students’ misdoings and suggestions for punishments. |
D.To help develop good communication between school and home. |
A.To help parents to know the importance of home activities. |
B.To show how the teacher can guide in home training. |
C.To prove parents all non professional advisors. |
D.To advice parents to teach kids math at home. |
A.thinks teachers should do better as professionals |
B.is worried about children’s performance at home |
C.is satisfied with the present state of school education |
D.believes time spent out of the classroom has been wasted@m |
A top NASA official and other leading scientists say that within four or five years they should discover the first Earth-like planet where life could develop, or may have already. A planet close to the size of Earth could even be found sometime this year.
At the annual American Astronomical Society conference this week, each discovery involving so-called “exoplanets” —those outside our solar system —pointed to the same conclusion:Quiet planets like Earth where life could develop probably are plentiful.
NASA’s Dew Kepler telescope and a lot of new research from the suddenly hot and competitive exoplanet field caused noticeable buzz at the meeting.Scientists are talking about being at “an incredible special place in history” and closer to answering the question. “Are we alone? For the first time, there’s an optimism that sometime in our lifetimes we’re going to get to the bottom of that,” said Simon Worden,an astronomer who heads NASA’s Ames Research Center. “If I were a betting man, which I am, I would bet we’re not alone.”
“These are big questions that reflect upon the meaning of the human race in the universe,” the director of the Vatican Observatory, the Rev. Jose Funes, said Wednesday in an interview at this week’s conference.
Worden told The Associated Press: “I would certainly expect in the next four or five years we’d have an Earth-sized planet in the habitable (可居住的) zone.”
What is very important in determining if we are alone in the universe?
A. Finding an Earth-like planet. B. Orbiting other stars.
C. Developing new telescopes. D. Finding more exoplanets.
What’s an exoplanet?
A. It’s a planet like Earth. B. It’s a planet outside our solar system.
C. It’s a planet orbiting the sun. D. It’s a planet where life have developed.
The underlined phrase “get to the bottom of” probably means “__________”.
A. understand fully B. make full use of
C. search for D. do more research on
From the passage we can learn that __________.
A. an Earth-like planet has been found
B. it’s been proved we are not alone in the universe
C. Jose Funes has found the meaning of the human race in the universe
D. the discovery of an Earth-like planet could happen in the near future
Perhaps the greatest changes in future robots will improve from their increasing ability to reason. The field of artificial intelligence is moving rapidly from university labs to practical application in industry, and machines of a new kind of robots are being developed, which can perform something involved in the process of understanding and planning, such as the management of a battlefield. Even the control of a large factory will be performed by intelligent computers. And there might be a possibility that these computers can design and make robots of their own.
Is there anything dangerous involved in this artificial intelligence progress then? Robot technology has been making people nervous ever since it was invented. Is it unreasonable to worry that robots will someday become too clever? Is it impossible that these human-like robots will start to think and plan for themselves? Will robots take over the world and force humans to give them energy to survive?
小题1: In 1995, about 700,000 robots were working in _____________.
A.Japan | B.the United States | C.Western Europe | D.the industrialized world |
A.Take care of roads. | B.Be used as medicine. |
C.Used as underground pipeline cleaner. | D.Take up jobs of building construction. |
A.Greatest changes in future robots. | B.The field of artificial intelligence. |
C.Machines of a new kind of robots. | D.Practical application in industry. |
A.It is possible that robots will be able to think like human beings. |
B.It is sure that robots might be able to manage battlefields. |
C.There is no doubt that computers can design and make robots of their own. |
D.It is proved that computers can’t reason like human beings. |
A.Future robotic technology might cause dangers. |
B.Future robotic technology might make people too clever. |
C.Future robotic technology might help to do all dangerous jobs. |
D.Future robotic technology might not survive because of its shortage of energy. |
