The alarm blows the horn intermittently and flashes the headlights, tail lights and other exterior lights. The engine cannot be started because the starter circuit will be cut. SETTING THE SYSTEM1. Turn the ignition key to the “LOCK” position and remove it.2. Have all passengers get out of the vehicle.3. Close and lock the front, sliding and back doors and hood.The indicator light will come on when the front, sliding and back doors and hood are closed and locked.As the front doors are locked, the system will give you a preparation time of 30 seconds before the setting, during which the front, sliding and back doors and hood may be opened to prepare for the setting.Be careful not to use the key when opening either front door. This will cancel the system. 4. After making sure the indicator light starts flashing, you may leave the vehicle. The system will automatically be set after the preparation time elapses. The indicator light will flash to show the system is set. If any of the front, sliding and back doors and hood is opened at that time, the setting is interrupted until it is closed and locked. Never leave anyone in the vehicle when you set the system, because unlocking from the inside will activate (使起动) the system.WHEN THE SYSTEM IS SETActivating the systemThe system will give the alarm and cut the starter circuit under the following conditions:If any of the front, sliding and back doors and hood is unlocked without using the keyIf the battery terminal is disconnected and then reconnectedAfter one minute, the alarm will automatically stop with the starter circuit cut kept on.Reactivating the alarmOnce set, the system automatically resets the alarm each time the front, sliding and back doors and hood are closed after the alarm stops.The alarm will be activated again under the following conditions:If any of the front, sliding and back doors and hood is openedIf the battery terminal is disconnected and then reconnectedStopping the alarmTurn the ignition key from the “LOCK” to “ACC” position. The alarm will be stopped with the starter circuit cut kept on. Stopping the alarm in this manner will keep the alarm from being reactivated when any of the front, sliding and back doors and hood is opened. Interrupting the settingWith the system set, the back door can be opened with the key without activating or canceling the system. While it is open, the front and sliding doors and hood may be opened in addition, and the system can be activated only by the battery terminal disconnection.To resume the setting, close and lock the front, sliding and back doors and hood. The back door must be closed with the key removed.CANCELLING THE SYSTEMUnlock either front door with the key, or unlock the sliding door with the key when it has been closed. This cancels the system completely and the starter circuit cut will be cancelled at once.INDICATOR LIGHTThe indicator light gives the following three indications when the system is in use.

Global warming can seem too 49 to worry about, or too uncertainsomething projected by the same computer 50 that often cant get next weeks weather right. On a raw winter day you might think that a few degrees of warming wouldnt be such a bad thing anyway. And no doubt about it: Warnings about 51 change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles. Comforting thoughts, perhaps. Unfortunately, however, the Earth has some discomforting news. From Alaska to the snowy peaks of the Andes the world is heating up right now, and fast. Globally, the 52 is up 1F over the past century, but some of the coldest, most remote spots have warmed much more. The results arent pretty.

You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.Today, as in every other day of the year, more than 3000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised.First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth.57. According to the author, the deaths among youth are mainly caused by _.A. traffic accidents B. smoking-related diseaseC. murder D. all of these58. Every day there are over_high school students who will become regular smoker.A.75 B.23 C.30 D.300059. By dropout the author means_.A. students who failed the examinationB. students who left schoolC. students who lost their wayD. students who were driven out of school60. The reason for declining adolescent smoking is that _.A.NCI has taken effective measuresB. smoking is prevented among high school seniorsC. there are many smokers who have died of cancerD. none of these61. What is implied but not stated by the author is that _.A. smoking rates among youth have declined very little B. there are now more female than male smokers among high school seniorsC. high smoking rates are due to the increase in wealthC. smoking at high school are from low socio-economic backgroundsPassage TwoQuestions 62 to 66 are based on the following passage.Every profession or trade, every art, and every science has its technical vocabulary. Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other vocations, like farming and fishery, that have occupied great numbers of men from remote times, the technical vocabulary, is very old. It consists largely of native words, or of borrowed words that have worked themselves into the very fiber of our language. Hence, though highly technical in many particulars, these vocabularies are more familiar in sound, and more generally understood, than most other technicalities. The special dialects of law, medicine, divinity, and philosophy have also, in their older strata, become pretty familiar to cultivated persons and have contributed much to the popular vocabulary. Yet every vocation still possesses a large bod
