Mars is a goal
worthy of
only the greatest efforts
that we can offer as a civilization.
We cannot fly to Mars
“on the wings of love”,
Or even fuel our rockets
with hopes and dreams.
Instead,
it is by the sweat of our brow,
the ache of our muscles
and the drive of our will
that we have always
blazed the trial of exploration.
And we will
continue to do so
in the future.

Confucius was born five hundred and fifty years before Christ. Unlike Jesus Christ, he did not bring words of God to the people. He was a clever teacher and a philosopher, looking for truth and wisdom. Most of his teaching was about life in this world.
Confucius was very keen to give people good rulers. Someone asked him, “What does a country need ” Confucius answered, “Enough food, a good army, and a good leader.” The people then asked, “Which one is the most important ” Confucius answered, “An army is not very important.

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships .One strength of the human condition is our possibility to give and receive support from one another under stressful conditions .Social support makes up of the exchange of resources among people based on their interpersonal ties .Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways .First, friends, relatives and co-workers may let us know that they value us .Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support .They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力)us from our worries and troubles. Finally, other people may give us instrumental support—money aid ,material resources, and needed services—that reduces stress by helping us resolve and deal with our problems.
65. Interpersonal relationships are important because they can .
A. make people live more easily
B. smooth away daily problems
C. deal with life changes
D. cure types of illnesses
66. The researches show that people’s physical and mental health .
A. lies in the social medical care systems which support them
B. has much to do with the amount of support they get from others

D. is related to their courage for dealing with major life changes

68. Helping a sick neighbor with some repair work in spare time is an example of ___________.
A. instrumental support

Fading beauty
She is widely seen as proof that good looks can last for ever. But, at nearly 500 years of age, time is catching up with the Mona Lisa.
The health of the famous picture, painted by Leonardo Da Vinci in 1505, is getting worse by the year, according to the Louvre Museum(卢浮宫博物馆) where it is housed.
“The thin, wooden panel on which the Mona Lisa is painted in oil has changed shape since experts checked it two years ago,” the museum said. Visitors have noticed changes but repairing the world’s most famous painting is not easy. Experts are not sure about the materials the Italian artist used and their current chemical state(化学状态).
Nearly 6 million people go to see the Mona Lisa every year, many attracted by the mystery of her smile. “It is very interesting that when you’re not looking at her, she seems to be smiling, and then you look at her and she stops,” said Professor Margaret Livingstone of Harvard University. “It’s because direct vision (视觉) is excellent at picking up detail, but less suited to looking at shadows. Da Vinci painted the smile in shadows.”
However, the actual history of the Mona Lisa is just as mysterious as the smile. Da Vinci himself loved it so much that he always carried it with him, until it was eventually sold to France’s King Francis I in 1519.
In 1911, the painting was stolen from the Louvre by a former employee, who took it out of the museum hidden under his coat. He said he panned to return it to Italy. The painting was sent back to France two years later.
During World War II, French hid the painting in small towns to keep it out of the hands of German forces.
Like many old ladies, the Mona Lisa has some interesting stories to tell.
70. What does the writer mean by “time is catching up with the Mona Lisa”
A. The painting woman is not so beautiful any more.
B. Ageing is something that affects us all.
C. The painting needs repairing.
D. At such an old age, she is no longer popular.
71. What makes the repair work difficult
A. The wooden panel is thin and old.
B. No one knows exactly what materials were used to create the painting and how it might respond to treatment.
C. The health of the painting is suffering.
D. Experts can’t agree on how to carry out repairs.
72. What makes her so mysterious according to Professor Livingston
A. The materials the Italian artist used. B. The way she smiles.
C. The way Da Vinci painted the smile. D. It plays a trick upon the human eyes

Libraries
No one can hope to own all the books he may want to read or use. [76] ┈
A good library contains thousands of books on all kinds of subjects. They are arranged on the shelves in certain order so that any particular book is easy to find. [77] ┈
[78] ┈ If we are looking for a particular book or a book on a particular subject, we will need to look up a card index. An author index lists authors alphabetically and tells which of their books are in the library. A subject index lists all the books in the library on any particular subject. Both indexes list classification numbers so that the books can be found easily.
[79] ┈ The books in the reference library are reference books and are for use inside the library only. They include dictionaries, directories, and encyclopedias. The reference section usually has a selection, of up-to-date newspapers and magazines. [80] ┈
---------------------------------------------------------------------------------------------
A. Most libraries have a reference section as well as the ordinary lending section.
B. Each subject is given a number according to a standard method of classification.
C. Fiction books, for example, are usually arranged alphabetically, according to the names of the authors. Nonfiction books are arranged subject by subject.
D. Readers can find the books they want to read by computers in every library.
E. Fortunately there are libraries in most towns that will lend us the books. Some are school libraries, others are public libraries. There may even be traveling libraries that visit remote areas.
F. Readers may also be able to read old issues of newspapers on microfilm by means of a microfilm reader. Storing information on microfilm saves a lot of valuable space. In university and some other libraries copies of many things, for example, documents, articles, and plans, are available on microfilm.
