听力原文: If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of year. A noted scientist, Ellsworth Huntington concluded from other men's work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities.
He found that cool weather is much more favorable for creative thinking than is summer beat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking. One mason may be that in the spring man's mental abilities am affected by the same factors that bring about great changes in all nature.

One of the most important ideals of the United States -- and an important part of the way many people in the United States see themselves -- is that of freedom. From the time of the American Revolution, when the colonists declared independence from England, the Untied States has attracted people seeking freedom.
A second ideal of great importance in the United States is that of role by the people. The framers of the Constitution of he United States strove to ensure that political power would lie in the hands of the voters, not a king or dictator. So they created a federal government composed of three branches -- legislative, executive, and judicial -- to prevent any one part of the government from becoming too powerful.
Another key value in the United States is that of the rights of the individual. The Bill of Rights is intended to safeguard the fights of the individual and guarantee protection from unjust treatment by the government or the majority. The importance of this protection is reflected in newspaper articles about violations of individual fights. Family, minority group, worker, student, and professional issues often center on questions of individual rights.
However, individuals and groups together struggle for prominence in the United States of today. For all of the importance of individualism, group identity also plays an important role in people's cultural values.
What is the ideal upheld in the US national anthem?

A. Freedom.
B. Straggle.
C. Equality.
D. Solidarity.
