There are two types of twins; identical and non-identical twins. Identical twins are formed from a single egg in mother’s body which divides to from two separate babies. Identical twins look the same, and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs a the same time, both of which grow to form babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.
  In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收養) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.
  There is a third type of twins, but it is a very unusual one. Twins which are joined together at birth are known in western countries as Siamese twins.
【小題1】It is difficult to tell identical twins apart because _______.

A.they are dressed in the same clothesB.they are dressed in the same color
C.they are very alikeD.they are standing side by side
【小題2】If the twins are easy to tell from each other, they are ______.
A.very probably non-identical twinsB.surely identical twins
C.surely identical twinsD.always a brother and a sister
【小題3】Which of the following is NOT true according to this passage?
A.In the 1970s and 1980s a scientist did some research into the two main types of twins.
B.In the week of tests, he tested their speed of thinking, their speech, their memory and some other things.
C.There were twins who had been separated from each other as soon as they were born.
D.Very often, separated twins were found to choose things of the same kind, the same shape and the same color.
【小題4】This passage mainly tells us _______.
A.the main types of twinsB.what has been found out about twins
C.how twins are formedD.how a scientist studied twins

Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria (衡量標準)in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager’s intended major, one located near a large city, and a campus where their daughter would be safe.
“The safety issue is a big one,” says Joe Mahoney, who quickly discovered he wasn’t alone in his worries. On campus tours other parents voiced similar concerns, and the same question was always asked: what about crime? But when college officials always gave the same answer -----“That’s not a problem here,”-----Mahoney began to feel uneasy.
“No crime whatever?” comments Mahoney today. “I just don’t buy it.” Nor should he: in 1999 the U.S. Department of education had reports of nearly 400,000 serious crimes on or around our campuses. “Parents need to understand that times have changed since they went to college,” says David Nichols, author of Creating a Safe Campus. “Campus crime mirrors the rest of the nation.”
But getting accurate information isn’t easy. Colleges must report crime statistics(統計數字) by law, but some hold back for fear of bad publicity(關注), leaving the honest ones looking dangerous. “The truth may not always be serious,” warns S. Daniel Carter of Security on Campus, Inc., the nation’s leading campus safety watchdog group.
To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.
【小題1】It is often difficult to get correct information on campus crime because some colleges ____.

A.receive too many visitors
B.mirror the rest of the nation
C.hide the truth of campus crime
D.have too many watchdog groups
【小題2】The underlined word “buy” in the third paragraph means _____.
A.mindB.admitC.believeD.expect
【小題3】We learn from the text that “the honest ones” in the fourth paragraph most probably refers to colleges _____.
A.that are protected by campus security
B.that report campus crimes by law
C.that are free from campus crime
D.that enjoy very good publicity
【小題4】What is the text mainly about?
A.Exact campus crime statistics.
B.Crimes on or around campuses.
C.Effective solutions to campus crime.
D.Concerns about kids’ campus safety.

Many teenagers feel that the most important people in their lives are their
friends. They believe that their family members,  especially their parents,  don’t
know them as well as their friends do. In large families,  it is often for brothers and sisters to fight with each other and then they can only turn to their friends for advice.
It is very important for teenagers to have one good friend or many friends. Even when they are not with their friends,  they usually spend a lot of time talking among themselves on the phone. This communication is very important in children’s growing up,  because friends can discuss something difficult to say to their family members.

科目:高中英語 來源:2012-2013學年廣東省高三第一次月考英語試卷(解析版) 題型:閱讀理解

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.  Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.  Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.  For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

1.The writer of this passage must be ______.

A.an American

B.a Chinese

C.a professor

D.a student

2.Which of the following statements is TRUE according to the passage?

A.Friendships between Americans usually extend deeply into their families.

B.Friendships between Americans usually last for all their lives.

C.Americans always show their warmth even if they are very busy.

D.Americans will continue their friendships again even after a long break.

3.From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.

A.warmly welcomed at the airport

B.offered a ride to his home

C.treated hospitably at his home

D.treated to dinner in a restaurant

4.The underlined words  “generous with our time” in Paragraph 3 probably mean ______.

A.strict with time

B.serious with time

C.careful with time

D.willing to spend time

5.A suitable title for this passage would probably be “______”. 

A.Friendships between Chinese

B.Friendships between Americans

C.Americans’ hospitality

D.Americans’ and Chinese’s views of friendships
