Passage Two

Questions 26 to 30 are based on the following passage.

Although April did not bring the rains we all hoped for, and although the Central Valley doesn’t generally experience the atmospheric (大氣的) sound and lightning that can accompany those rains, it is still important for parents to be able to answer the youthful questions about thunder and lightning.

The reason that these that these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lighting we see flashing(閃爍) down to the earth from a cloud is actually flashing up to a cloud from the earth? Our eyes cheat us into thinking we see a downward motion when it’s actually the other way round. But then, if we believe only what we think we see, we’d still insist that the sun rises in the morning and sets at night.

Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between the earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on the earth every second.

Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashes reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval between the flash and the crash to learn how close they are to the actual spark.

A. when it is April B. when the field is dry

C. People can seldom see lightning flashes running between two clouds or between the earth and a cloud.

D. The thunderstorms happening above the earth can provide enough power to produce about 100 lightning strikes every second.

29. What does the word “ spark” in the last paragraph probably refer to ?

A. Cloud B. Rain C. Thunderstorm D. Lightning flash

30. What does the passage imply?

A. Seeing is believing.

B. We should never trust what we see or hear.

C. People may easily make mistakes in their understanding of nature.

Passage Three

The year at an American college is divided into 2 semesters or 3 quarters. Semesters are 15 weeks; quarters are 10 weeks. American college students usually attend school from September to May. They can also study during the summer.

Students choose their classes a few weeks before the start of each term. Universities offer a great many classes in the students’ main area of study and in other areas as well. Students must take both. These include science, mathematics, computer, history and English. Other classes may be just for fun, like dance, theater or sports. Tests usually are given in the middle of the term and at the end. The final examinations are extremely important. In some classes, the professor asks the students to write a research paper or complete a certain task instead of taking a test.

Classes usually are organized through lectures. For example, a student may attend 2 or 3 lectures a week by the professor. As many as several hundred students sit at each lecture. Sometimes they also attend a smaller class to ask questions and discuss what the professor says. These small classes are taught by professor’s assistants. In science classes, students also have a long laboratory class each week.
