中华民族的传统文化博大精深、源远流长。早在2 000多年前,就产生了儒家学说和道家学说,以及其他很多在中国思想史上有地位的学说流派,这就是有名的“诸子百家”。从孔夫子到孙中山,中华民族传统文化有它的很多珍贵品质。比如“天下兴亡,匹夫有责”的爱国情操,“民为邦本”、“民贵君轻”的民本思想和“己所不欲,勿施于人”的行为准则。

答案:

The traditional Chinese culture, both extensive and profound, starts far back and runs a long, long course. More than 2 000 years ago,there emerged in China Confucianism and Taoism, and many other theories and doctrines that figured prominently in the history of Chinese thought,all being covered by the famous term “the Hundred Schools of Thought”. From Confucius to Dr. Sun Yat-sen,the traditional Chinese culture presents many precious ideas. For example, they lay stress on. patriotism as embodied in the saying“Everybody is responsible for the rise or fall of the country.”, the populist ideas that “People are the foundation of the country.”and that “The people are more important than the monarch”and the code of conduct of “Don’t do to others what you don’t want others to do to you”.

1、【题目】Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging.

Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secret chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participation of the nervous system.

The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. The term “endocrine” was introduced shortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.

1.What is the author’s main purpose in the passage?

A.To explain the specific functions of various hormones.

B.To provide general information about hormones.

C.To explain how the term “hormone” evolved.

D.To report on experiments in endocrinology.

2.The passage supports which of the following conclusions?

A.The human body requires large amounts of most hormones.

B.Synthetic hormones can replace a person’s natural supply of hormones if necessary.

C.The quantity of hormones produced and their effects on the body are related to a person’s age.

D.The short child of tall parents very likely had a hormone deficiency early in life.

3.It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed that chemical integration occurred only___.

A.during sleep.

B.in the endocrine glands.

C.under control of the nervous system.

D.during strenuous exercise.

4.The word “liberate” could best be replaced by which of the following?

A.Emancipate B.Discharge C.Surrender D.Save

5.According to the passage another term for exocrine glands is___.

A.duct glands

B.endocrine glands

C.ductless glands

D.intestinal glands.

1、【题目】Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children. These roles were firmly fixed for most people, and there was not much opportunity for women to exchange their roles. But by the middle of this century, men’s and women’s roles were becoming less firmly fixed.

In the 1950s, economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in childcare, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam.

In terms of numbers, the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on “overtime” work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods.

In the 1970s, the feminist movement, or women’s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women’s jobs as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion.

Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations.

1.Which of the following best express the main idea of Paragraph 1?

A.Women usually worked outside the home for wages.

B.Men and women’s roles were easily exchanged in the past.

C.Men’s roles at home were more firmly fixed than women’s.

D.Men and women’s roles were usually quite separated in the past.

2.Which sentence best expresses the main idea of Paragraph 2?

A.The first sentence.

B.The second and the third sentences.

C.The fourth sentence.

D.The last sentence.

3.In the passage the author proposes that the counterculture___.

A.destroyed the United States.

B.transformed some American values.

C.was not important in the United States.

D.brought people more leisure time with their families.

4.It could be inferred from the passage that___.

A.men and women will never share the same goals.

B.some men will be willing to exchange their traditional male roles.

C.most men will be happy to share some of the household responsibilities with their wives.

D.more American households are headed by women than ever before.

5.The best title for the passage may be ___.

A.Results of Feminist Movements

B.New influence in American Life

C.Counterculture and Its consequence

D.Traditional Division of Male and Female Roles.
