　　四級英語專項閱讀習題***一***

　　Car crashes are the leading cause of injury and death among U.S. children, and though most of us now think of car seats as standard baby equipment, about half of all children under the age of four who died in vehicle accidents last year were not

　　restrained. It is calculated that only about two-thirds of children aged five to fifteen buckle their seat belts.

　　Moreover, the traffic-safety agency estimates that even among parents who always strap their children in, 85% are not doing it properly. They often don’t know where best to place the kids, don’t use the proper restraint for their age and weight, or don’t install the safety seats properly. Despite the reports about front seats collapsing onto back seats when certain car models get in accidents, the safest place in the car for any child up to the age of 12 is still the back seat. Babies up to 9 kg and one year old should ride in rear-facing infant seats.

　　Never place a child under age 12 in the front seat with a working passenger-side air bag. These devices are discharged at 320 km/h and can be triggered by low-speed fender benders. They have killed 77 kids in the U.S. since 1993. If you must place a child in front, make sure the passenger-side bag is switched off.

　　Children over age one should ride in forward-facing safety seats with a five-point harness system. A child who weighs at least 18 kg or at least lm high can graduate to a booster seat that elevates her so that the standard shoulder and lap belt fits properly.

　　62. What does the author mainly discuss in this passage?

　　[A] How to avoid car crash.

　　[B] How to design safer baby equipment.

　　[C] How to educate children properly.

　　[D] How to properly secure children in the ear.

　　63. Which of the following is NOT among the "improper ways" mentioned in the passage?

　　[A] They don’t know where best to place the child.

　　[B] They don’t have the safety equipment for the child.

　　[C] They don’t use the proper restraint for the kid’s age and weight.

　　[D] They don’t install the safety seats properly.

　　64. Which of the following is the best seat for the children under 12?

　　[A] Forward-facing seats.

　　[B] Rear-facing seats.

　　[C] Front seats.

　　[D] Back seats.

　　65. The author indicates that a passenger-side air bag __

　　[A] might not be dangerous if switched off

　　[B] is designed for the safety of children

　　[C] is discharged at 320 km/h and will not triggered by other factors

　　[D] is not working ifa child sits in the seat

　　66. What does the word "graduate" ***Line 2, Para. 4*** mean?

　　[A] Finish schooling.

　　[B] Change to something else.

　　[C] Collapse.

　　[D] Stand.

　　四級英語專項閱讀習題答案

　　62.D主旨題。文章指出，造成兒童車禍死亡的一大原因是他們沒有受到適當的保護，文章還介紹瞭如何根據兒童的年齡、體重、身高等正確使用安全座椅或安全帶以保護他們在車中的安全，所以D正確。

　　63.B資訊明示題。文章第二段第二句指出，家長通常不知道讓孩子坐哪裡最好，或是他們沒有用適合孩子的安全帶，或是安全座椅安裝得不正確，即A、C、D都是不恰當的行為，但並沒有提及B項，故選B。

　　64.D資訊明示題。文章第二段最後指出，the safest place in the car for any child up to the age of 12 is still the back seat，即12歲以下的孩子應該坐車後座，所以D正確。

　　65.A綜合推斷題。文章第三段最後一句指出，如果你不得不讓孩子坐車前座，你就必須關掉前座旁的安全氣囊，由此推斷，關掉後的安全氣囊對孩子應該沒有危險，所以A正確。

　　66.B語義題。文章最後一段指出，“體重超過18公斤或高於1米的孩子可以_______兒童增高座椅。”選項中A意為“畢業”，B意為“改換”，C意為“倒塌”，D意為“站立”，只有B符合句意，為答案。

　　四級英語專項閱讀習題***二***

　　Newspapers often tell us of floods in some parts of the United States.

　　Nearly every year on the great central drainages heavy rains and melting snow cause the waters to pour out the mountains and plains, to turn brooks into torrents, and to swell quiet streams into wild uncontrolled rivers. From Cairo to New Orleans, and from Pittsburgh to Paducah, the cry "River rising!" is a familiar yet fearful voice. . . When the rivers sometimes become too high or too swift to be controlled communities are flooded, families flee from their homes, croplands are washed out, and transportation comes to a halt. Hunger, disease, and death follow the wild waters.

　　Although given less publicity, the agricultural damage done by the many smaller, more frequent floods usually far exceeds the losses caused by the very grand ones. In the Central States, ditches and drains cause the flows from spring rains and melting snow to run far more rapidly than in the days before white men settled on the land. Once, excess spring flood waters emptied into lakes and swampy lands, there to be detained for slow release into stream and rivers. Now, systematic drainage has actually eliminated these natural reservoirs.

　　In the more rolling sections of the East, spring runoff was formerly absorbed and held temporarily in the porous soils beneath the unbroken expanse of forest. When large areas were converted to farm use, removal of the forest and the practice of up-and-down hill plowing deprived the soils of much of their ability to catch and store water.

　　The effects of eliminating the natural forest cover are shown in the gullied farm lands and widened stream channels found in some densely settled areas. Partly because the stream channels are more or less filled with material washed down from the uplands, and partly because storm runoff has increased, the channels are today no longer able to carry all the flow from heavy rains. This explains why the streams overtop banks far more often than in the days before settlement.

　　26. The best title for the selection would be______.

　　A. River Rising! River Rising! B. Forests and Floods

　　C. Flooding in the U. S. D. The Results of Flooding

　　27. All of the following cause floods EXCEPT______.

　　A. heavy rain B. melting snow

　　C. increasing storm runoff D. porous soil

　　28. The author states that______.

　　A. lakes and swamps once acted like natural reservoirs

　　B. up-and-down hill plowing catches and stores water

　　C. stream channels are the best carriers of water

　　D. floods are easily prevented and controlled

　　29. According to the selection, streams overtop their banks partly because______.

　　A. material from higher land is washed into them

　　B. ditches and drains lead into them

　　C. rivers become too swift

　　D. snow melts more rapidly nowadays

　　30. The floods which are given most publicity______.

　　A. cause no damage

　　B. cause the most damage

　　C. cause less agricultural damage than the many smaller, more frequent floods

　　D. far exceed the smaller, more frequent floods in agricultural loss
