[11:39.65]Section B
[11:42.81]Directions: In this section, you will hear 3 short passages.
[11:49.49]At the end of each passage, you will hear some questions.
[11:54.08]Both the passage and the questions will be spoken only once.
[11:59.22]After you hear a question,
[12:01.84]you must choose the best answer from the four choices marked A), B), C) and D).
[12:08.74]Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
[12:15.19]Passage One
[12:17.07]Do you know that vegetables can be grown in climates they are not accustomed to?
[12:22.43]Cool climates vegetables are now able to be grown in places as hot as Hawaii.
[12:28.34]In Hawaii, engineers have been able to actually make those vegetables live in cooler climates.
[12:34.79]That way they grow faster and taste better.
[12:38.18]What these engineers have been using is cold seawater.
[12:41.90]The temperature of seawater is much lower than the air temperature.
[12:46.06]How do they use it? They place pipes in the soil and the cold water flowing
[12:51.20]through them cools the earth.
[12:52.95]This stimulates plant growth and enables gardeners
[12:56.23]in tropical climates to grow crops from cooler climates.
[13:00.38]Also, some of these pipes are exposed to the air and they make the moisture
[13:05.53]form little water drops and thus irrigate the gardens.
[13:09.46]What is especially appealing about this process
[13:12.42]is that nothing damaging to the natural environment is being used.
[13:17.44]Another innovative use for cold ocean water is to cool buildings.
[13:22.15]Engineers believe that, for example,
[13:24.99]the entire west coast of the United States could be air-conditioned using seawater.
[13:31.01]We all know there are certain types of chemicals used in air conditioner,
[13:35.27]which not only pollutes the air but also bring damage to the ozone.
[13:40.19]If we could cool the city by using seawater, the environment of the whole city
[13:45.34]will be improved and the ozone will be protected,
[13:48.51]which will be beneficial to ourselves in return.
[13:52.01]Questions 16 to 19 are based on the passage you have just heard.
[13:57.48]16. What is the report mainly about?
[14:17.81]17. How are the pipes used in Hawaii?
[14:37.78]18. What are the other advantages of using seawater?
[14:59.02]19. Why does the speaker mention air-conditioning?
[15:18.72]Passage Two
[15:20.56]As a result of rising university costs,
[15:23.84]many students are finding it necessary to take on part-time job.
[15:28.00]To make finding those jobs easier,
[15:30.19]our services put together a listing of what's available locally.
[15:34.34]For some students, these part-time jobs could lead to full-time work after graduation,
[15:39.81]as they may offer experience in their own field,
[15:43.20]whatever in field of finance, marketing or even management.
[15:47.36]For example, National Saving Bank offers a job on a half time basis.
[15:52.93]That's twenty hours a week.
[15:54.79]Retail stores and restaurants have positions requiring fewer hours.
[15:59.72]Even less time is expected of those providing child-care.
[16:03.55]We have a number of families registered with us
[16:06.94]who were looking for baby sitters for as few as 4 hours a week.
[16:11.09]For students who prefer outdoor work,
[16:13.94]there are seasonal positions right on campus, working with the gardening teams.
[16:18.64]These often require the most time and are the least flexible in terms of scheduling.
[16:23.56]To see a complete list of these and other available jobs,
[16:27.39]including the salary offered and the hours required,
[16:30.78]stop by our office.
[16:32.42]Oh, and be sure to bring a resume with you.
[16:35.26]When you find something that interests you,
[16:37.89]we'll put you in touch with the person offering it.
[16:40.51]In addition, our counselors will give you hints about successful interviewing.
[16:45.55]We do hope you would like our service and get some help from us.
[16:49.59]We'll try to have more information to help you. Suggestions are welcomed.
[16:54.84]Questions 20 to 22 are based on the passage you have just heard.
[17:00.42]20. What is the purpose of the talk?
[17:19.71]21. What should students bring with them to the office?
[17:35.18]22. What do all of the jobs have in common?
[18:00.44]Passage Three
[18:02.17]In the late 1400s, when Christopher Columbus returned to Spain from the western part of the earth,
[18:09.28]he brought with him a sample of corn.
[18:11.80]Corn is a popular and nutritious type of food we have today in our daily diet.
[18:17.59]The corn that Columbus introduced to Europe was originally native to Mexico.
[18:22.73]The peoples of the Americans probably started to plant this grass as early as 5000 B.C.
[18:29.95]After about a thousand years, they had developed highly productive types of corn which later
[18:36.74]became the basis for the great pre-Columbian civilizations.
[18:41.11]Actually, many countries regarded corn as one of their basic crops.
[18:45.70]To certain degree, we can say that many ancient cities were built on corn.
[18:51.39]Corn is one of the major foods both for men and some domesticated animals,
[18:57.30]such as chicks and pigs. The corn and the people who cultivated it developed together.
[19:03.31]Without humans to care for it, corn could not survive.
[19:07.90]There were times when some natural disasters stroke corn planting.
[19:12.83]The people who planted corn made great effort to protect it from being destroyed.
[19:18.19]They tried to gather the seeds to enlarge the planting areas.
[19:22.23]The planting people tried various ways to enhance the production of corn.
[19:27.15]They tried to get rid of the weeds and fertilized corn at proper times.
[19:32.08]They also have to make sure corn is watered when there's a lack of rain.
[19:36.89]Questions 23 to 25 are based on the passage you have just heard.
[19:42.56]23. What is the main topic of this passage?
[20:03.46]24. Where was corn probably first cultivated?
[20:24.34]25. Why would corn die out without human care?
