Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children. According to United States requirements, life preservers must design, reversible capable of being quickly adjusted to fit the uninitiated individual, and must be so designed as to support the wearer in the water in an upright or slightly backward position.

Sufficient buoyancy(浮力) to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage. Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.?The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.

The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster. Thus, the life be reversible that it is nearly impossible to get it on wrong. Catches, straps, and ties should be kept to a minimum. In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities. A suitable life also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.

1. The passage is mainly about____.

A) the uses of life preservers

B) the design of life preservers

C) the materials for life preservers

D) the buoyancy of life preservers

2. According to the passage, a life be first of all ____.

A) adjustable B) comfortable C) self-evident D) self-righting

3. United States Coast Guard does NOT require the life preserver to be made ____.

A) with as few strings as possible

B) capable of being worn on both sides

C) according to each wearer's size

D) comfortable and light to wear

4. By “the uninitiated individual” (Para. 1, Line. 4) the author refers to the person ____.

A) who has not been instructed how to use a life preserver

B) who has a little experience in using a life preserver

C) who uses a life preserver without permission

D) who becomes nervous before a disaster

5. What would happen if a person were supported by the life preserver in a wrong position?

A) The waves would move him backwards.

B) The water would choke him.

C) He would immediately sink to the bottom.

D) He would be exhausted or unconscious.

答案解析:

1. B。文章主要講述了救生衣的設計。間接題型段首主旨題。C項和D項都是對救生衣設計中設計材料的說明。A項爲陷阱，指救生衣的用途，儘管開頭提到，但範圍不着邊際。故只有B是正確選項。

2. D。根據文章，救生衣首先會自動扶正。事實細節題。本文第三段主要討論救生衣落水位置，應設計的能“自動扶正”,或稍向後仰。B項是對材料的描述，範圍太窄，而A和C不合題意，因此D是正確答案。

3. C。美國海岸巡邏隊不需要救生衣根據穿戴者的尺寸生產。事實細節題。A項和B項都涉及method，其相關部分見最後一段第三句，A，B，D三項都是文章中提及的，C項與本題無關的內容，因此應該選C。

4. A。“the uninitiated individual”作者指的是不知道怎麼使用救生衣的人。語義指代題。根據文章最後一段第一句，我們可推出“the uninitiated individual”就是指的那些不知道怎麼使用救生衣的人。故A是正確選項。

5. D。如果一個人沒有正確使用救生衣，就會發生什麼?細節辨別題。第三段第一句後半句中a face-down position和本題中的 in a wrong position相對應。因此選項D“他可能太累了或者是已經失去知覺”是正確答案。

Among the more colorful characters of Leadville’s golden age were r and his second wife, Elizabeth McCourt, better known as “Baby Doe”. Their history is fast becoming one of the legends of the Old West. Horace Austin Warner Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. “Great deposits of lead are sure to be found here.” he said.

As it turned out, it was silver, not lead, that was to make Leadville’s fortune and wealth. Tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco.『It was his custom to “grubstake” prospective miners, in other words, to supply them with food and supplies, or“grub”, while they looked for ore, in return for which he would get a share in the mine if one was discovered.』①He did this for a number of years, but no one that he aided ever found anything of value.

Finally one day in the year 1878, so the story goes, two miners came in and asked for “grub”. Tabor had decided to quit supplying it because he had lost too much money that way. These were persistent, however, and Tabor was too busy to argue with them. “Oh help yourself. One more time won’t make any difference,” He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in return for which they gave Tabor a one-third interest in their findings. They picked a barren place on the mountain side and began to dig. After nine days they struck a rich vein of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the “Pittsburgh Mine,” made 1 300 000 for Tabor in return for his $17 investment.

Later Tabor bought the Matchless Mine on another barren hillside just outside the town for $117 000. This turned out to be even more fabulous than the Pittsburgh, yielding $35 000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor, and later became lieutenant governor of the state.

1. Leadville got its name for the following reasons EXCEPT ______.

A. because Tabor became its leading citizen

B. because great deposits of lead is expected to be found there

C. because it could bring good fortune to Tabor

D. because it was renamed

2. The word “grubstake” in paragraph 2 means ______.

A. to supply miners with food and supplies

B. to open a general store

C. to do one’s contribution to the development of the mine

D. to supply miners with food and supplies and in return get a share in the mine, if one was discovered

3. Tabor made his first fortune ______.

A. by supplying two prospective miners and getting in return a one-third interest in the findings

B. because he was persuaded by the two miners to quit supplying

C. by buying the shares of the other

D. as a land speculator

4. The underlying reason for Tabor’s life career is ______.

A. purely accidental

B. based on the analysis of miner’s being very poor and their possibility of discovering profitable mining site

C. through the help from his second wife

D. he planned well and accomplished targets step by step

5. If this passage is the first part of an article ,who might be introduced in the following part?

A. Tabor’s life.

B. Tabor’s second wife, Elizabeth McCourt.

C. Other colorful characters.

D. Tabor’s other careers.

答案解析:

1. C 細節題。因爲Leadville可以爲Tabor帶來鉅富。這一點不是Leadville得名的原因，因爲在文章第二段中，講到這一點時，提及三個原因：A.因爲Tabor成爲當地的居民代表人物，B.因爲在Leadville有豐富的鉛的儲藏量。D.因爲Leadville是因爲Tabor重要而起的名。

2. D 詞彙題。第二段中grubstake的詞義與D所述內容是相同的，即“供給探礦者資金，衣物，食品以及其他物品”。

3. A 細節題。Tabor第一次真正發財是他爲兩名礦工提供資助，爲此他獲得他們礦資源三分之一的股份。見文章第三段4-9行內容：兩名開礦者從Tabor那兒借走價值17美元的物品，作爲回報，Tabor獲得他們礦資源三分之一股份。於是兩位開礦者在一座山旁的不毛之地開始挖掘，九天之後，發現了銀的富礦，於是Tabor又將兩人的股份全買下，這樣，銀礦屬於Tabor一個人所有，這個礦就是後來著名的“匹茲堡”礦。Tabor用17美元的投資換來了130萬美元的收穫。

4. B 推斷題。由原文可知泰勃的財產來源是有一定偶然性的'，但是畢竟也是基於他開創“grubstake”模式，因爲A、D都不對，C更是沒有根據，因爲他還沒有娶第二位夫人這一切就發生了。分析泰勃的做法，會得出B選項所示的結論。

5. B 推斷題。如果本文是一篇文章的第一部分，那麼在文章的第二部分將介紹誰呢?可以從文章第一句分析出來，在Leadville的黃金年代，其多彩的特點當中，Tabor及其第二任妻子Elizabeth McCourt是值得大書特書的，接着，文章都在講述有關r發家致富的歷史，如先買下匹茲堡礦，後又買下Matchless礦，最後成爲市長，代理州長，等等，所以涉及到的全是男主人公，因此下邊再講的話，應成爲女主人公即Elizabeth McCourt的天地了，她是Tabor的第二任妻子。這是順理成章的事。
