Byrne turned the key in the heavy lock and put it calmly in his pocket.He did so much more from caution than from any kind of fear.This was the only entrance to the house,and he did not mean to be caught unawares by any danger from outside.He wondered if Tom Corbin had been as cautious the night before.Though Tom would be away for at least three days,Byrne had a strange feeling of his nearness.In the stillness he seemed to hear Tom’s voice.He looked round quickly, for the tricks of hearing are the most realistic of all.But there were only the women.It seemed impossible that Tom should not be there.

The girl,carrying a smoky oil lamp,led Byrne upstairs.He threw open one after another the doors along the passage.At this,the girl stopped and raised the lamp in each doorway,staring at him meanwhile.Satisfied he was the only guest,Byrne came to the last door,which the girl threw open herself.

"You sleep here,sir" she said,giving him the lamp."Your friend slept here too.It’s our most comfortable bed."

"Good night,miss," he said politely.

Her lips moved in reply, but he did not catch the words.Her eyes never for a moment left his face.He stepped in,and as he turned to close the door she was still standing there motionless.He paused,and in the silence he thought he again heard the sound of Tom’s voice.The sound ferrified him now ,not only because it seemed much nearer but also because he imagined a note of warning in it.

1.Why did Byrne take the key with him?

There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.

By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed.

The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.

1.The study of the effects of salt on high blood pressure was carried out ______.

a.as members of the same family tend to use similar amounts of salt

b.to explore the long-term use of a sodium based substance

c.because it was proven that salt caused high blood pressure

d.because of the availability of chemically pure salt and its derivatives

2.The main difference between "S" and "R" rats is their ______.

a.need for sodium 22

b.rate of mating

c.reaction to salt

d.type of blood

3.We can infer from the article that sodium 22 can de used to ______.

a.control high blood pressure

b.cure high blood pressure caused by salt

c.tell the "S" rats from the "R" rats

d.determine what a sodium chloride metabolism is like

4.The most beneficial results of the research might be ______.

a.development of diets free of salt

b.an early cure for high blood pressure

c.control of genetic agents that cause high blood pressure

d.the early identification of potential high blood pressure victims

5.Which of the statements best relates the main idea of this article?

a.When salt is added rats and human beings react similarly.

b.The near future will see a cure for high blood pressure.

c.The medical field is desperately in need of research.

d.A tendency toward high blood pressure may be a hereditary factor.

Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed.

Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.

Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and their white counterparts.

1.The passage is mainly discussing __________ .

a.the necessity of social change

b.certain factors that determine the ease with which social changes occur

c.two different societies

d.certain factors that promote social change

2.______ is one of the factors that tend to promote social change.

a.Joint interest

b.Different points of view

c.Less emotional people

d.Advanced technology

3.According to the passage, which of the following is NOT true?

a.Social change tends to meet with more difficulty in basic and emotional aspects of society.

b.Disagreement with and argument about conditions tend to slow down social change.

c.Social change is more likely to occur in the material aspect of society.

d.Social change is less likely to occur in what people learned when they were young.

4.The expression "greater tolerance"(paragraph 1) refers to _____ .

a."greater willingness to accept social change"

b."quicker adaptation to changing circumstances"

c."more respect for different beliefs and behavior"

d."geeater readiness to agree to different opinions and ideas"

5.Social change is less likely to occur in a society where people are quite similar in many ways because ________ .

a.people there have got so accustomed to their conditions that they seldom think it necessary to change

b.people there have identical needs that can be satisfied without much difficulty

c.people there are easy to please

d.people there are less disputed

The Colonel ask Ashenden a good many questions and then suggested that he had particular qualifications for the Secret Service. Ashenden knew several European languages and the fact that he was a writer provided excellent cover: on the pretext that he was writing a book he could, without attracting attention, visit any neutral country.

It was while they were discussing this point that the Colonel said,"You know you might get material that would be very useful to you in your work. I’ll tell you an incident that occurred only recently. Very dramatic. A foreign government minister went down to a Mediterranean resort to fecover from a cold and he had some very important documents with him that he kept in a despatchcase.

"A day or two after he arrived, he picked up a blonde at some restaurant or other, and he got very friendly with her. He took her back to his hotel, and when he came to himself in the morning the lady and the despatch-case had disappeared. They had one or two drinks up in his room and his theory is that when his back was turned the woman slipped a drug in his glass."

"Do you mean to say that happened the other day?"said Ashenden wearily.

"The week before last."

"Impossible,"cried Ashenden. "Why, we’ve been putting that incident on the stage for sixty years, we’ve written it in a thousand novels. Do you mean to say that life has only just caught up with us?"

"Well, I can vouch for the truth of the story." said the Colonel, "And believe me, the government concerned has been put to no end of trouble by the loss of the documents."

"Well sir, if you can’t do better than that in the Secret Service," sighed Ashenden, "that I’m afraid that as a source of inspiration to the writer of fiction, it’s washout."

The United States is a federal union of 50 states.The capital of national government is in Washington,D.C.(District of Columbia).The federal constitution sets up the structures of the national government and lists its powers and activities.The constitution gives Congress the authority to make laws which are necessary for the common defense and the good of the nation.It also gives the federal government the power to deal with national and international problems that involve more than one state.All powers that are not given to the federal government by the constitution are the responsibility of the individual states.

The federal government has three branches--the executive,the legislative,and the judicial.The legislative brandch makes the laws,executive branch carries out the laws,and judicial branch interprets the laws.The President heads the executive branch and the Supreme Court heads the judicial branch.The legislative branch includes both houses of Congress--the Senate and the House of Reprsentatives.The constitution limits the powers of each branch and prevents one branch from gaining too much power.For example,Congress can pass a Law the President may sign it.Nevertheless,the Supreme Court can declare the law unconstitutional and nullify it.

All government in the United States is "of the people,by the people and for the people".The people elect the President and the members of Congress.However,the President appoints the heads of federal departments and the Supreme Court judges.Every citizen votes in secret.Consequently,no one knows for whom and indevidual votes.The people believe that their government should provide a frameword and order within which they are left free to run their own lives.

Anne Whitney, a sophomore at Colorado State University,first had a problem taking tests when she began college."I was always well prepared for my tests.Sometimes I studied for weeks before a test.Yet I would go in to take the test,only to find I could not answer the questions correctly.I would blank out because of nervousness and fear.I couldn’t think of the answer.My low grades on the tests did not show what I knew to the teacher." Another student in microbiology and similar experiences.He said ,"My first chemistry test was very difficult.Then,on the second test,I sat down to take it,and I was so nervous that I was shaking.My hands were moving up and down so quickly that it was hard to hold my pencil.I knew the materical and I knew the answers.Yet I couldn’t even writen them down!"

These two young students were experiencing something called test anxiety.Because a student worries and it uneasy about a test,his or her mind does not work as well as it usually does.The student can’t write or think clearly because of the extreme tension and nervousness.Although poor grades are often a result of poor study habits,sometimes test anxiety causes the low grades.Recently,test anxiety had been recognized as a real problem,not just an excuse or a false explanation of lazy students.

Special university counseling courses try to help students.In these courses,counselors try to help students by teaching them how to manage test anxiety.At some universities,students take tests to measure their anxiety.If the tests show their anxiety is high, the students can take short courses to help them deal with their tension.These courses teach students how to relax their bodies.Students are trained to become calm in bery tense situations.By controlling their nervousness,they can let their minds work at ease .Learned information then comes out without difficulty on a test.

An expert at the University of California explains."With almost all students, relaxation and less stress are felt after taking out program.Most of then experience better control during their tests. Almost all have some improvement.With some,the improvement is very great."
