Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(壽命) can be prolonged.
Gene technology can help people to give birth to healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遺傳的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government must take care to control gene technology.
小題1:What does “these two killers” in the second paragraph refer to?
A．Gene technology and another treatment of the two diseases.
B．The two murderers who killed the cloned baby.
C．The two diseases of cancer and heart disease.
D．Hereditary diseases and cancer.
小題2:What’s the main idea of the third paragraph?
A．How gene technology can be applied in the field of treating hereditary diseases.
B．Gene technology can be used to clone human babies.
C．Gene technology can help people to give birth to a baby.
D．Gene technology can help the English imperial family out.
小題3:In what way gene technology can help to treat hereditary diseases?
A．Using gene technology, people with hereditary diseases can have more living days.
B．Using gene technology, the scientist finds the wrong gene and corrects it.
C．Using gene technology, human babies can be cloned.
D．Doctors can cure cancer and heart disease with the help of gene technology.
小題4:What is the main purpose of writing this passage?
A．Expressing the writer’s idea that gene technology will benefit people.
B．Telling people the disadvantages of gene technology.
C．Telling the readers that gene technology will not benefit people.
D．Explaining that gene technology will also do harm to the humanity.

Play allows children to use their creativity while developing their imagination and physical, cognitive (認(rèn)知的), and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.
Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce (順從) to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.
Children’s development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children’s vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children’s world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.
Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children’s learning willingness. Social-emotional learning is best integrated (融合) with academic learning; it is concerning if some of the forces that enhance children’s ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.
小題1:Compared with undirected play, play which is controlled by adults ________.
A．doesn’t benefit the children at all
B．doesn’t help develop leadership and group skills
C．makes children become more active
D．helps increase physical activity levels
小題2:The third paragraph mainly tells us that ________.
A．play offers parents a good chance to establish good relationships with children
B．children’s development is greatly influenced by relationships with parents
C．play helps children better express their views
D．play offers parents a unique opportunity to see the world from a different perspective
小題3:From the last paragraph, we know that ________.
A．play can’t help children become adapted to the school setting
B．play makes social-emotional learning and academic learning separated
C．play is beneficial to social-emotional learning as well as academic learning
D．it is necessary to strengthen children’s academic development at the expense of others
小題4:Which of the following statements is NOT true?
A．Undirected play can help children develop team spirit.
B．Play can improve children’s willingness to learn.
C．Play helps adults gain a better understanding of the children’s thoughts.
D．Adults shouldn’t be involved in children’s play.

 Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources(資源), we are short of(缺乏) others, for example, fresh water(淡水). It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps(水龍頭) when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

Online Communication
In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letter. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication.
But a story about online communication changed my mind.
An old man, who suffered a lot from Parkinson’s disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard.
I, therefore, managed to get an E-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities（能力） that few other products can match.
E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn’t want to have a face-to-face talk with your manager, you might talk with him through E-mail even if you are in the same office.
Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could easily spend half a day clearing junk ads.
Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I’m sure there is and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting… even in the world of modern communication.
As I listen to the sound of the modem(調(diào)制解調(diào)器), I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life.
小題1:What is the most probable meaning of the underlined word “junk” in paragraph6?
A．old and uselessB．New and usefulC．Short but valuableD．Long but clear
小題2:What does the writer think of online communication?
A．It should replace old-fashioned letters completely.
B．It is perfect and always does good to you.
C．It is extremely useful and convenient, but it may be inconvenient or even harmful.
D．It does more harm than good.
小題3:What caused the writer to become interested in E-mail and online communication?
A．The sound of the modem.B．His own illness.
C．The changing of his life.D．A sick old man’s experience.
小題4:According to the writer, traditional means of communication will never disappear because ________.
A．they are convenient and popular though they are slow
B．they help to keep the friendly relationship between people
C．most people cannot keep up with the development of technology
D．modern means of communication does too much harm
小題5:How did the sick old man keep in touch with his family members?
A．With the help of his computer.B．By writing letters with his pen.
C．By making telephone calls.D．By visiting them regularly.

Astronomers have captured(捕獲) the first direct image of a planet being born.
Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.
The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.
Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.
Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.
Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.
Planets can change orbits(軌道) after forming, so it’s difficult to answer such questions by studying older planets.
“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.
Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮強過) them. Kraus and Ireland used two techniques to overcome this problem.
One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.
The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
小題1:The research on younger planets helps scientists _____________.
A．study why planets change orbits after forming
B．understand how planets move around their stars
C．a(chǎn)nswer questions about the age of stars and planets
D．know the relationship between planets and their stars
小題2:Why are young planets like LkCa 15b hard to discover?
A．Their stars are brighter than them..B．They are very far from the earth.
C．They are generally too small.D．They rarely form.
小題3:According to the text, Kraus and Ireland _____________.
A．have been working in the same university
B．observed the planet on a volcano in Hawaii
C．used two new methods in the observation
D．cut holes in the mirrors when observing
小題4:Which of the following would be the best title for the text?
A．Youngest planet seen as it’s forming.
B．Planet 450 light years away discovered.
C．World’s first direct image of a planet taken.
D．New technique helps discover young planets.

If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again.       knows this, but nobody would think of     the fact.
Yet there are many people who        to know that the memory works in the same way. When someone says that       has a good memory, he       means that he keeps his memory in practice     exercising it very     , either consciously or unconsciously. When someone else says that his memory is     , he means that he does not give it enough      to become strong. The position is exactly the same as that of       people, one of      exercises his arms and legs by playing ball, while the other       in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own      , But if he tells us that he has a poor memory,      of us think that his parents are to blame, or that he is just     , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind,       all of us can improve our strength and our memory by the same means that      .
Have you ever       that people who cannot read or write usually have      memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.
In a word, if you want to have a good memory, do practice       things。

It seems that many college graduates are unsure of what to do with their lives, so they jump back into the college scene by default(違約). But graduate school is costly, time consuming and requires a lot of in-depth study, and also parents will lay down more money and banks will supply more student loans.
However, there are some students who should be pursuing graduate degrees. Teachers, lawyers, doctors, professors and ministers are a few examples of those who will benefit from class work past a bachelor’s degree. Their professions call for additional courses and more specialization and therefore higher education is a must. Still, all students in general should not adopt the idea that graduate school is necessary for individuals who want to make more money. Working hard right after college can lead to promotions in the future. It seems that it does more good to network or internship（實習(xí)）with professionals while pursing a bachelor’s degree than it does to complete a master’s and distant oneself from the world of work.
If a student graduates with a four-year degree and immediately enters the work force , he will most likely start an entry-level pay. In a couple of years this employee will gain seniority and experience, therefore increasing their chance for pay rise. He will learn the information at his job-site that he did not learn in school. His bachelor’s degree loan can be immediately chipped away ,and his maturity level can increase as real work related responsibilities set in. But, if the student pursues a master’s degree, he may be able to demand more pay initially when he finally goes job hunting, but years of serious money making as well as work experience will already be lost.
Students should not shy from the workforce just because uncertainty follows graduation. Those who pursue a graduate degree just because they do not want to leave school and because they view the “real world” as scary should think again. Using graduate studies as a hiding place from the full-time job is a waste of time.
小題1:College graduates who go to work can _____ than those who pursue graduate degrees.
A．make more money in the futureB．a(chǎn)cquire more experience
C．get a better jobD．become more responsible
小題2:The underlined words “chipped away” can most possibly be replaced by_______.
A．given outB．set downC．thrown awayD．paid off
小題3:What would be the best title for the passage?
A．College graduates shouldn’t pursue graduate degrees
B．College graduates should think twice
C．How can college graduates make more money?
D．Students use graduate school to avoid reality

Today, there are many chances for those who wish to continue their education. However, nearly all require some break in one’s career in order to attend school full time.    　　
Part-time education, that is, attending school at night or for one weekend a month, tends to drag the process out over time and puts the completion of a degree program out of reach of many people. Additionally, such programs require a fixed time commitment which can also impact negatively on one’s career and family time. 
Of the many approaches to teaching and learning, however, perhaps the most flexible (靈活的) is that called distance learning. Distance learning is an educational method which allows the students the flexibility to study at his or her own pace to achieve the academic goals which are so necessary in today’s world. The time required to study may be set aside at the student’s convenience. Additionally, the student may enroll in distance learning courses from actually any place in the world, while continuing to pursue their chosen career. Individual assistance may be available via regular airmail, telephone, fax machine, teleconferencing and over the Internet.
Good distance learning programs are characterized by the inclusion of a subject evaluation tool with every subject, so a student doesn’t need to travel away from home to take a test. Another characteristic of a good distance learning program is the equivalence (等同) of the distance learning course with the same subject materials as those students taking the course on the home campus. The resultant diploma or degree should also be the same whether distance learning or on-campus study is employed. The individuality of the professor/student relationship is another characteristic of a good distance learning program. In the final analysis, a good distance learning program has a place not only for the individual student but also the company or business that wants to work in partnership with their employees for the educational benefit, professional development, and business growth of the organization. Supporting distance learning programs for their employees gives the business the advantage of retaining (留住) career-minded people while contributing to their personal and professional growth through education. 　　
小題1:According to the passage, which of the following is NOT a disadvantage of part time education?
A．It requires some break in one’s career. 　　
B．It tends to last too long for many people to complete a degree program.　　
C．It affects one’s career.　　
D．It gives the student less time to share with the family.
小題2: Which of the following is NOT an advantage of distance learning?  　
A．The student may choose his or her own pace.　
B．The student may study at his or her convenience.　　
C．They can pursue their chosen career while studying.　　
D．Individual assistance comes through regular airmail, telephone and fax machine.
小題3:What benefit will distance learning program bring to a business?   　　
A．Attracting more talented people.　　
B．Good image of the business.　　
C．Better cooperation with universities.　　
D．Further training of employees and business growth.
