Passage 1
Albert Einstein had a great effect on science and history. An American university president once commented that Einstein had created a new outlook, a new view of the universe. It may be some time before the average mind understands fully the identity (特性) of time and space and so on — but even ordinary men understand now that the universe is something larger than ever thought before.
By 1914 the young Einstein had gained world fame. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited opportunities for study, but soon his peace and quiet were broken by the First World War.
Einstein hated violence. The misery of war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work.
In the years following the First World War, honors were increasingly heaped on him. He became the head of the Kaiser Whilhem Institute of Theoretical Physics. In 1921 he won the Nobel Prize for Physics, and he was highly honored in Germany until the rise of Nazism (纳粹主义) when he was driven from Germany because he was a Jew.
21.The first paragraph is mainly about _____.
A.a new outlook of the universe
B.the feelings of an American college president
C.the change in human thought caused by Einstein
D.the difficulty in teaching Einstein's theory
解：C
[解析]本题是主旨题 第一段的主题句是第一句“Albert Einstein had a great effect on science and history”表明爱因斯坦对科学和历史都有极大的影响，而第二句说明了爱因斯坦使人们对世界观，对宇宙有了一个新的认识。因此选项为C。
22. From the second paragraph, we know Albert Einstein ____.
A.enjoyed world popularity
B.was the head of an academy
C.was a famous teacher
D.enjoyed studying wars
解：A
[解析]本题是细节题 依据是第二段第一句话“By 1914 the young Einstein had gained world fame.”选项中A.enjoyed world popularity 符合题义。Popularity的意思与fame 的意思相似。
23. Which of the following statements about Einstein is true?
A.He achieved more than any other scientists in history.
B.Our ideas about the universe differ from one another because of him.
C.He kept working until peace came in 1918.
D.His research practically stopped during the First World War.
解：D
[解析]本题是细节题 本题可以用排除法，本题的依据是第三段。第三段表明爱因斯坦深受战争的影响“he sat unhappily in his office doing little. He lost interest in his research ”而且最后一句“Only when peace came in 1918 was he able to get back to work...”也表明爱因斯坦在第一次世界大战期间研究工作实际上是停止了。因此选D。
24. In the years following the First World War,_____.
A.Einstein began to be accepted even by ordinary men
B.more and more honors were granted to Einstein
C.Einstein became the head of the Prussian Academy of Science
D.Einstein was not honored in Germany until the rise of Nazism
解：B
[解析]本题是细节题，要用排除法 ，本题的依据是最后一段的第一句话“In the years following the First World War , honors were increasingly heaped on him.” Heap的意思就是“成堆，很多”和 “more and more”是近义词。
25. It can be inferred from the third paragraph that _____.
A.Albert Einstein was interested in nothing but science
B.Einstein was forced to serve in the German army
C.Einstein made a lot more breakthroughs in his research after the First World War
D.his reputation was ruined because of Nazism
解：C
[解析]本题是推理题
Passage 2
Could you imagine your parents choosing your husband or wife for you? And can you imagine not setting eyes on him or her until your wedding day? This situation is common in India, the Middle East and many parts of Africa. Marriage customs around the world often differ from our own. We don't realize that people in other places often get married in very different ways — and with different motives.
In many countries, marriage is a practical matter. A marriage provides a safe and stable home for the husband and wife. It also joins two families, which benefits the couple's parents and makes them happy. Marriage also brings children, making sure the couple will be taken care of in old age. Because a marriage is important for the whole family, some cultures don't let young people choose whom to marry.
Just as there are many different reasons for marriage, there are also many different wedding rituals. Every culture has its own ways of bringing good luck to the happy couple. In a typical Western wedding, the bride seeks good luck by wearing “something old, something new, something borrowed and something blue.” Something old represents the past. Something new represents success in the future. Something borrowed reminds the bride she can get help from her friends and family. And something blue reminds her to be true to her husband.
In Poland, one wedding tradition is not only lucky, but also very practical. The wedding guests pin money to the bride's dress while she is dancing. The money is meant to bring kick and to help the young couple build their new life. In Bermuda, the young couple plants a tree in the yard of their new home. Once they move in, they take good care of the tree and make it grow. The planting of the tree is a good metaphor (比喻) for marriage. A truly good marriage is something that grows with care.
26. Which of the following statements DOES NOT support the idea that marriage is a practical matter?
A.The couple may have a safe and stable home through their marriage.
B.The parents had better help their children choose whom to marry.
C.A marriage benefits the couple's parents and makes them happy.
D.A marriage brings children who will take care of the couple when they are old.
解：B
[解析]本题是细节题本题的主要依据是第二段，第二段的主题句是第一句“In many countries,marriage is a practical matter.”而A、C、D是developing sentences是用来支持主题句的。而B是一个结果。

28. In a typical Western wedding, the bride wears something blue to ________.
A.seek good luck

解：D
[解析]本题是细节题主要依据是第三段“And something blue reminds her to be true to her husband”
