X-rays are high energy waves that are invisible. 1.For example,doctors can see inside the human body and security guards at airports can see inside your handbag. In 1895,the German scientist,Wilhelm Rontgen,discovered X-rays by accident. He called them X-rays because he hadn't seen such a form of radiation before. 2.Wilhelm took the first X-ray picture of the bones of his wife's hand after the discovery. In 1901,he received the first Nobel Prize in Physics for his discovery.

X-rays are valuable in medicine because then can see through certain parts of the body. Doctors can take pictures to see which bones are broken or to find out which teeth have holes. The X-rays are strong enough to pass through the skin and muscles,but they cannot pass through hard objects like bones. In the picture,hard objects like bones are white area3.

There are some situations in which X-rays cannot give you a clear picture. Some organs,for example,may prevent X-rays from showing a broken bone. For this reason,computed tomography(CT)was invented. A person is put inside a scanner,which is a large tube-shaped machine. 4. A computer puts together all of these images,which can show doctors more than a normal X-ray can.

5.Patients must wear protective clothing for the parts of their body that are not X-rayed. Doc- tors and helpers who work with X-ray machines must wear lead aprons and stand behind screens.

A.Then the person is X-rayed from all sides.

B.Objects that X-rays go through appear dark.

C.In mathematics,X means something unknown.

D.An X-ray machine is used to take these pictures.

E.X-rays,however,can also do harm to your body.

F.However,they can be an essential tool for finding out what's wrong with you.

G.They are useful because they can pass through many things that normal light cannot.

It’s generally acknowledged that raising a child has geographic features. A recent survey, for example, looked at the personalities parents wanted their children to have in different countries. The finding was fascinating: Dutch parents focused on rest, cleanliness and routine; Italian parents preferred their children to be even-tempered, well-balanced and likeable; American parents, meanwhile, were more likely to want their kids to be intelligent or cognitively advanced.

The US preference represents the shift in the way American parents raise their children, a transition from the so-called latchkey kids of the 1980s to the helicoptered children of today. With more parents adopting the kind of intensive parenting style common in the US, parenting in European nations, traditionally more relaxed, is changing.

Intensive parenting is a type of parenting that requires a significant amount of time and money, including scheduling children for additional activities, as well as advocating for their needs and talents in communications with schools. It’s not limited to a small circle of parents but the dominant cultural model of parenting in the US.

The increasing fear of inequality makes parents feel the need to help drive their children’s education. The inequality, in their opinions, is making it critical for the kids not to be left behind. And so they will assume a parenting style that is more intense and more success-oriented. Thus the intensive parenting approach has become a parenting style influencing the overall parenting culture in Europe.

The intensification of parenting has consequences for nations, parents and children. One of the problems is that it increases economic inequality. In the 1960s, for example, when there was less emphasis on developing children’s talents and interests, parents across social classes spent similar amounts of time and money on their kids.

Experts also point to the large volume of parenting books, blog posts and articles now available to those raising families. Even if parents are skeptical of expert advice, they are still influenced by it. Turning kids into well-rounded and successful personalities is naturally becoming their life-long pursuit.

1.What does the study mentioned in the first paragraph indicate?

A.A well-balanced child is more 1ikeable in Dutch.

B.How kids are brought up varies from area to area.

C.A kid’s cognitive ability is fixed by geographic features.

D.Being clean is preferred by American parents.

2.What can be concluded about intensive parenting?

A.It needs much involvement of parents. B.It makes kids more relaxed than before.

C.It has been criticized. D.It is out of date in the US.

3.What a possible result can intensive parenting bring?

A.Weakening the ties between parents and their kids.

B.Intensifying the inequality among the people economically.

C.Relieving the depression and anxiety of parents.

D.Meeting a strong protest from most European parents.

4.What’s the best title of the passage?

A.American Parenting Mode Swings Back B.Returning to the Traditional Parenting Mode

C.Parenting Makes Parents over Stressed D.Intensive Parenting Is Sweeping through the US

For many in the United States,Arab-Americans are an invisible part of the population．Though Arab-Americans as a community have made great contributions to American society in fields from literature to politics to medicine,many Americans know very little about Americans of Arab backgrounds．

Arab history in the United States goes back to the late 1800’s when large numbers of Arab immigrants first began making their journey to a land known simply as“Amreeka”．

Historians generally describe Arab immigration to America in two waves．The first wave took place between 1860 and 1924．The first wave consisted of Lebanese and Syrian,and some Egyptian immigrants．These new immigrants,who were mostly Christian,came to America in search of better opportunities．Even the doomed Titanic,which set sail for America in 1912,had close to a hundred Arab passengers aboard．The majority of Arab-Americans today are descendents of the first wave of immigrants;they are the third or more generation Americans．

The second wave of immigrants followed after World War Ⅱ,caused by political unrest in the Middle East．This second wave of immigrants consists of mainly Arab Muslims（穆斯林）and continues to this day．

Arab-Americans make up 3 million of the population in the United States,according to demographers．And quite different from popular belief,64 percent of them are American-born．Eighty-two percent of Arab-Americans are US citizens．

Arab-Americans are beyond the national average in both education and income．Education is important among Arab-Americans;82 percent have high school diplomas,36 percent have bachelor’s degrees or higher,and 15 percent have graduate degrees．The-median（中位数的） average income among Arab-Americans is $39 580,which is higher than the US average．
