1. Passage Twenty-Eight On November 19， 1863， Abraham Lincoln went to Gettysburg in Pennsylvania to speak at the National Soldiers Cemetery. The Civil War was still going on. There was much criticism of President Lincoln at the time. He was not at all popular. He had been invited to speak at Gettysburg only out of politeness. The principal speaker was to be Edward Everett， a famous statesman and speaker of the day. Everett was a handsome man and very popular everywhere. It is said that Lincoln prepared his speech on the train while going to Gettysburg. Late that night， alone in his hotel room and tired out， he again worked briefly on the speech. The next day Everett spoke first. He spoke for an hour and 57 minutes. His speech was a perfect example of the rich oratory of the day. Then Lincoln rose. The crowd of 15，000 people at first paid little attention to him. He spoke for only nine minutes. At the end there was little applause. Lincoln turned to a friend and remarked， “I have failed again.” On the train back to Washington， he said sadly， “That speech was a flat failure， and the people are disappointed” . Some newspapers at first criticized the speech， but little by little as people read the speech， they began to understand better. They began to appreciate its simplicity and its deep meaning. It was a speech which only Abraham Lincoln could have made. Today， every American school child learns Lincoln’s Gettysburg Address by heart. Now everyone thinks of it as one of the greatest speeches ever given in American history. In 1863， Abraham Lincoln was ( ) .

A. very critical

B. unpopular

C. very popular

D. very courteous

4. Passage Twelve What are the differences between public and private in American higher education? A big difference involves money. Public colleges and universities charger for an education just like private schools. But state schools cost less because they get money from the states that started them to educate local citizens. As a result， out-of-state and international students usually pay more than state residents， at least the first year. The state with the most residents， almost forty million， is California. Its systems of two-year and four-year colleges and universities are among the largest in the world. But the example we are going to focus on today is to the north of California， in a much smaller state on the West Coast: Oregon. The University of Oregon， located in Eugene， is one of the campuses in the Oregon University System. The cost for undergraduates this year is $6，000 for state residents. Housing is an additional $8，000. Non-residents pay the same for housing——but almost $20，000 for tuition and fees. Let’s see how these numbers compare to a private college in Oregon. Lewis and Clark College in Portland has 4，000 students， compared to 20，000 at the University of Oregon. Housing costs $800 more than at the state school. But the big difference is tuition. The published price at Lewis and Clark is almost $34，000. Yet Lewis and Clark is one of the few American colleges to offer financial aid for international students. Each year it awards financial aid to twenty students from other countries. And it says the average award last year was 19，000 dollars. That would make Lewis and Clark cheaper for international students than the University of Oregon. But， of course， prices alone do not say anything about the quality of a school or the value of an education. The costs of tuition and housing in Lewis and Clark College are ( ) .

A. both more expensive than in the University of Oregon

B. cheaper for foreign students than in the University of Oregon

C. the same as that in the University of Oregon

D. cheaper than those of the University of Oregon for the state residents

3. Passage Twenty-Four 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 changes 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 ( 一分为二). This is one reason why change has not come more quickly to Black American as compared to other American minorities， because of the sharp difference in “appearance between them and their white counterparts” .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 an 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.

3. Passage Eleven Doctors say anger can be an extremely damaging emotion， unless you learn how to deal with it. They warn that anger can lead to heart disease， stomach problems， headaches， emotional problems and breast cancer. Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm and reasonable way. Others burst with anger， screaming and yelling. But still others keep their anger inside. They cannot or will not express it. This is called 【repressing】 anger. For years some doctors claim that both repressing and expressing anger can be dangerous. They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙). They spend the heart rate， raise blood pressure or sugar level in the blood. As a result， the angry person feels excited and is ready to react. The violent reaction may lead to high blood pressure. However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it. They believe that those who keep their anger inside may face a greater danger of heart disease. Most doctors agree that it is important to learn how to deal with anger. They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about. If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably. They also believe that a good way to deal with anger is to find humor in the situation that has made you angry. After all， it is much healthier to laugh than to get angry .The best way to deal with anger is ( ) .

A. to scream and yell

B. to keep anger inside

C. to express anger calmly
