Part I Writing
Dormitory Life
For most university students, dormitory life is a new experience. Most students have never lived far away from their parents before coming to university. They have always had their parents to depend on for advice and guidance, and when they become university students, their lives begin to change.
There are striking differences between home life and dormitory life. Students must begin to be responsible for their own action. They must depend on themselves to get up in the morning on time for class, to eat properly, to keep their clothes and themselves clean, and to set aside an appropriate amount of time for study and relaxation. They must also learn to take care of their money, making sure to preserve enough for both necessities and for fun.
In general, there are both good and bad points about life in student-dormitory. Often, dormitory rooms are small and crowded. This lack of space can limit one’s privacy and make it difficult for students to concentrate on their studies. On the other hand, in a dormitory, students have a great deal more freedom than they might have at home. They can act according to their own will and desire than to that of parents.
Part II Reading Comprehension
(Skimming and Scanning)
1.【解析】[D]屬同義轉換題，本題是一種排除選擇題。根據題幹中的中心詞「movement to do something」，可以將答案定位在小標題「Moving to Survive」下第二段的前兩句話，「Like the shark, most animals use movement to find food. They also use locomotion to escape enemies, find a mate, and explore now territories」。該句與題幹是一種同義轉換，選項A、B和C在原文中均有提及，所以不是正確選項;答案D在原文沒有提及，所以是正確答案。
2.【解析】[B]屬細節推斷題。題幹考查汽車、火箭和潛艇的例子是為了說明什麼，其中的「examples of automobiles, rockets and submarines」是關鍵詞，可以將答案定位在文章小標題「Moving to Survive」下第三段的前兩句話，「Humans have the added advantage of using their various inventions to move about in just about any kind of environment. Automobiles, rockets, and submarines transport humans from deep oceans to as far away as the moon」，第二句話所舉例子正是為了說明第一句話的內容，這與B項意思一致，而其他選項在文中均未提及。

3.【解析】[A]屬細節推斷題。分析題幹，本題考查鯊魚在水中快速遊動的關鍵是在什麼。其中的「key」是關鍵詞，可以將答案定位在小標題「Skin Is the Key」下首段的第一句話，「The biologists discovered that the skin of the shark is the key to the animal’s high efficiency in swimming through the water」，這與選項A完全一致，所以直接選擇A即可。其他選項在文中均有提及，但是都不符合題幹的要求。
4.【解析】[D]屬細節推斷題。題幹中的「collagen fibers to the greatest extent」是關鍵詞，可以將答案定位在小標題「Skin Is the Key」下第二段的第一句話，「The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming」。這與選項D的內容完全一致，所以答案選D項，而其他選項原文均未提及，為幹擾項。
5.【解析】[C]屬細節推斷題。題幹中「a belted radial tire」是關鍵詞，可以將答案鎖定在文章小標題「Source of Energy」下第一段的第三句話，「Just as a radial tire is inflated by pressure, so, too, is the area just under the shark’s collagen 『radials』」。其中的「just as」和「so」正說明了兩者的相似之處在於「inflated by pressure」，所以答案應該是C。選項A和B是兩者的不同之處，選項D在文中沒有提及。
6.【解析】[A]屬細節推斷題。題幹中的關鍵詞是「a laminar flow」，所以可以將答案鎖定在文章小標題「Dolphin Has Speed Record」下，根據該節第一段的倒數第三、四句話，「Normally when a fish or other object moves slowly through the water, the water flows smoothly past the body. This smooth flow is known as laminar flow.」。題幹是對這兩句話的改寫，所以正確答案是A選項。其他三個選項的意思均不符合「a laminar flow」的定義，與題幹要求不符。
7.【解析】[C]屬同義轉換題。題幹中「a slug」和「a mouse」均為關鍵詞，可以直接定位在小標題「Other Animals Less Efficient」下第一段的第二句話，「It uses so much energy ... a mouse traveling the same distance uses only one twelfth as much energy」。題幹是對該句的同義改寫，所以正確答案是[C]12 times，其他選項均與原文內容不符。
8. 【解析】feeling the vibrations of a struggling prey鯊魚靠感受獵物遊動的震動來發現獵物。
9. 【解析】collagen fibers 在Skin Is the Key中，第二、三句話，The fibers are called collagen fibers.
10. 【解析】some fantastic involuntary changes 在Source of Energy中，第二段倒數第一句話就是本題答案。

16. W:Oh my goodness! I』ve spilled the soup all over the kitchen floor.
M:I』ll get the mop and clean the floor for you.
Q:What is likely the relation between them?
【解析】［B］本題問的是說話人雙方是什麼關係。女士說：天哪，我把湯灑了廚房一地。男士說：我來拿拖把擦。很顯然，兩人是夫妻關係。

Now you』ll hear two long conversations.
Conversation One
W:It’s important that you all understand that quartz heaters operate on a totally different principle than common convection heaters, yes?
M:Could you give us an example of a convection heater?
W:Okay, but first you tell me what convection means.
M:Hmm, well, you said in the last class, I think, that convection is the transferring of heat by a liquid or a gas.
W:Right. A heater is using convection when it warms the air in the room, and the air, in turn, warms the people and objects in the room. A hot-water radiator, a stove and a forced air furnace are all convection heaters. A quartz heater on the other hand heats the objects and people in the room without heating the air. It does this by producing radiation heat that travels like light waves. When the quartz crystal in the heater vibrates at a particular frequency, its energy is turned into infrared radiation. The radiation is then directed at the objects by means of a reflector. Is that clear? Let’s move on to how room design can affect heating efficiency.
Questions 19 to 22 are based on the conversation you have just heard.
19.What had the instructor probably been discussing in the previous class?
【解析】［D］從學生的回答中you said in the last class, I think, that convection is the transferring of heat by a liquid or a gas中可推斷出上節課教師講的是對流的問題。
20.What does the instructor ask the student?
【解析】［B］教師讓學生解釋一下什麼是對流。教師說：but first you tell me what convection means.
21.According to the instructor, how is the quartz heater different from other types of heaters?
【解析】［A］石英加熱器不會將空氣加熱，只加熱房間裡的物體。A quartz heater on the other hand heats the objects and people in the room without heating the air.
22.What is the purpose of the reflector on a quartz heater?
【解析】［D］從下面這句中可聽出答案：The radiation is then directed at the objects by means of a reflector.
Conversation Two
M:Do you know what happened to me today? I was so embarrassed.
W:What?
M:Well, Dr. Brown’s class finished 10 minutes early, so I went to the library between classes. I knew I didn’t have much time, but I wanted to get these books on the Industrial Revolution. I looked them up in the card catalogue and went right to the stack and found them. So I put them in my bookbag and headed back towards the door. Then it happened. The exit gate in front of the door wouldn’t open, and the guard immediately warned me that I hadn’t checked out my books. He thought I was trying to steal them.
W:That must』ve been embarrassing. But why didn’t the exit gate open?
M:I asked them that. It seems that the books in the library are all magnetically coded, and when you check them out, the librarian behind the desk demagnetizes them, then the exit gate will open.
W:How interesting! I still don’t quite understand how they do it, though. I』ll have to go to the library and see it for myself.
Questions 23 to 25 are based on the conversation you have heard.
23.Why did the man decide to go to the library?
【解析】［A］布朗教授的課提前十分鐘下課了，因此我決定在課間去趟圖書館。Dr.Brown’s class finished 10 minutes early, so I went to the library between classes.
24.After getting the books, what did the man do?
【解析】［D］男生拿到書之後直接把書塞到書包裡了So I put them in my bookbag and headed back towards the door.從這句話中可得出答案。
25.According to the man, what happens to all the books in the library?
【解析】［B］從男生的話中可看出圖書館裡的所有書都經過特殊編碼了。It seems that the books in the library are all magnetically coded.
Section B
Passage One
Do you have a tough math test coming up? Then listen to some classical piano music just before the test. You might end up with a higher score. Researchers at a university in California conducted an experiment. They asked a group of college students to listen to some piano music by a famous 18th century composer before taking a math test. They were surprised to find that the students』 scores jumped 8 to 9 points. The music seems to excite nerve activity in the brain, similar to the activity that occurs when a person is figuring out a math problem. However, the scientists warn that before you get too excited about applying this method to your math test, you should remember that brain exciting effects last only 10 or 15 minutes. Would rock music work as well as the piano music did? No, the scientists say. In fact, the less complex music might even interfere with the brains reasoning ability.
Questions 26 to 28 are based on the passage you have just heard.
26.What is this passage mainly about?
【解析】［C］根據文章的內容，科學家們做了一項測試，在做數學題的時候放音樂，學生的成績普遍提高好幾分，我們可以推斷出這篇文章是講音樂對數學測驗結果的影響，所以選C。
27.Why can classical music play a positive role in problem solving?
【解析】［A］科學家們說，搖滾音樂就不能像鋼琴曲那樣對成績有所幫助，只有那些不是特別複雜的音樂會對大腦的思維有影響，能夠刺激你的神經活動。所以選A。
28.What is one of the findings of the research?
【解析】［B］科學家們說，必須記住這種讓大腦興奮起來的效果只會維持10到15分鐘，不會持續太長的時間，所以選B。
Passage Two
I had to go to Amsterdam last week for a conference. I arrived at the airport in plenty of time and checked in, but I only had one small case so I decided to take it on the plane as hand luggage. As the flight was not due to board for 45 minutes, I went to a cafe, sat down, and ordered a cup of coffee.
While I was sitting there drinking my coffee and reading the paper, I was vaguely aware of a woman and her child coming to sit at the next table. I did not pay much attention to them, though, and when my flight was called I reached for my case and left.
An hour later, the plane was in the air and I decided to look at the conference program to see what I wanted to attend. Imagine my horror when I opened the case and found that it was full of picture books and children’s toys—and imagine what the woman must have thought about a case full of men’s clothes and scientific papers!
Questions 29 to 31 are based on the passage you have just heard.
29.Why did the speaker go to a cafe?
【解析】［B］說話人離登機還有很長的時間，於是他去咖啡廳喝咖啡來消磨時間。He wanted to kill time before boarding the plane.
30.What was in the speaker’s case?
【解析】［D］本題答案在最後一句a case full of men’s clothes and scientific papers，說話人的箱子裡裝滿了男士的衣服以及一些科技文件。

When we got there, we put up our tent and went to explore. As we returned, we heard our daughter Susie cry out and then we saw a bear enter our camp. Tom wanted his father to chase him away. His father said, 「No, it’s dangerous to chase a bear. And don’t let him chase you.」 Susie said: 「What shall we do?」 「Maybe we ought to climb a tree.」 Tom said: 「No, we』ve got to get him out of there. He might go to sleep in our tent.」 「Maybe we could make him leave if we put some honey outside for him to eat.」 Susie suggested. Then I said: 「How are you going to get the honey? It’s in the tent.」 We watched the bear enter the tent and heard him upset everything inside. 「It’s foolish for us to try to catch him,」 said my husband. 「Leave him alone and wait for him to come out.」 We waited but the bear stayed inside. We had to sleep in the car.
Questions 32 to 35 are based on the passage you have just heard.
32.Where have the family decided to go in the vacation this summer?
【解析】［A］聽完全文可以得知這個家庭還未決定好去哪裡度假。所以正確答案為They haven’t reached a decision yet.
33.Who do you think saw the bear first?
【解析】［A］從短文中這一段可以看出答案。As we returned, we heard our daughter Susie cry out and then we saw a bear enter our camp，因此顯然是女兒Susie先看到了熊。
34.What did they do when they saw a bear enter their tent?
【解析】［B］他們站在外面一直在討論該怎麼對付這隻熊，但最終什麼都沒做。因此，正確答案為They stayed outside the tent and did nothing.
35.What did the bear do in the tent?

Part Ⅳ Reading Comprehension
(Reading in Depth)
Section A
47.【解析】[B]save 本文主要講理智的購物可以省很多錢的問題。你購買一件物品或者一份服務的方式真的可以給你省錢或者讓你多花錢，所以此處空格填save，「節省」。
48.【解析】[G]simple 就拿吹風機作一個簡單的例子。空格處用simple形容例子符合文章所表達的意思。
49.【解析】[C]best 如果你要買一個吹風機，當你選了一個外觀你非常喜歡而且價格又是最便宜的，你一定認為你買了最好的東西。make the best buy即是說買了最好的東西。
50.【解析】[I]in 以怎樣的價格用固定短語in price。最便宜的價格就是the cheapest in price。
51.【解析】[K]model 意為「樣式，型」。當你把它買回家，你才發現它要花兩倍於較貴的吹風機所花的時間來吹乾你的頭髮。a more expensive model更貴的一款。

Section B
Passage One
57.【解析】[C]推斷題。本文討論了友誼的重要性。不論是青少年還是老年人，都需要朋友的陪伴。沒有人是孤立的，每個人都是社會的一部分，都需要他人的愛、陪伴和關心。文章第二段表明人都需要陪伴和歸屬感。文章第二段提到沒有朋友的青少年和喪偶的老年人常常會有心理問題，並提到陪伴和歸屬感是他們共同的需求，所以C為正確答案。答案A和B都過於武斷，作者只是說一般而言，並沒有說一定會，所以不對。
58.【解析】[C]細節題。「No man is an island」 (Line 1, Para. 3) 的意思是，每個人都是社會的一部分。第三段第二句話解釋了這句引言的意思， 「In other words, we are all parts of society」，所以C為正確答案。
59.【解析】[C]細節推理題。友誼的親密程度主要取決於人的個性。見第四段第二句，「The degree of intimacy of friendship varies depending on the personality of the individuals ...」，所以C為正確答案。
60.【解析】[D]細節推理題。作者認為多數人的親密朋友並不多。見第五段第三句，「Close friends can be formed at any stage in one’s life but they are usually very rare」在人生的任何階段都可以交到親密的朋友，但數量通常很少，由此推斷D為正確答案。
61.【解析】[C]詞彙題。「irrespective」(第五段最後一句)這個詞語的意思是「不論，不考慮」。見最後一句，「Irrespective of the level of intimacy, all friendships are based on ...」不論親密的程度如何，任何友誼都是建立在互惠、誠實和一定的友愛和關懷的基礎之上的。根據上下文，可推測出這個詞語的意思是「不論，不考慮」。所以C為正確答案。
Passage Two
62.【解析】[C]細節題。問題問「當她的丈夫離家出走時，Eileen Doyle怎麼樣?」根據第一段第二行「Eileen was astonished...」可以斷定C「(她)不明白為什麼」應該是正確答案。其餘三項均不符合文章意思。
63.【解析】[A]細節題。問題問「離開家庭的大多數人」。該題較簡單，解題依據應該是文章第二段，其大意為:一年中的每一天都有一小幫男人和女人悄然收拾幾件行李，沒有留下任何紙條或說一聲再見(「...without so much as a note or goodbye...」，其中without so much as為重要句型，表示「甚至……都沒有」)，最後一次關上前門離家出走了，把他們的債務、他們的憂慮，還有迷惑不解的家庭拋在身後。A項正確。
64.【解析】[D]細節題。文章第四段第二、三句說明那些被遺棄的人甚至寧願自己的配偶已經死亡，至少死亡不會意味著自己被拋棄或失敗，所以要比被遺棄的感覺好點。B、C兩項屬於四級考試中典型的陷阱式幹擾項，因為B項中的「pride and confidence」及C項中的「rejection or failure」在原文中皆有出現，馬虎的考生可能不假思索就選了B或C，正好中了圈套，其實稍微細心一點就會發現B、C和文章所說的並不是一回事。第四段第三句「At least it...」中的it是指death而不是題幹中主語所指。
65.【解析】[D]推斷題。問題的題幹應該在第四段最後一句，所以答案在此「...Worse than that,... an unfinished marriage,...wait seven years before...」，D項正是這種意思。
66.【解析】[B]細節題。依據第五段第二行「It’s typical of the kind of personality which seems able to ignore other people’s pain and difficulties.」 B項說「這是一種自私行為」，為正確答案。A 「這是種絕望行為」;C 「這是突然決定的結果」;D 「這是沉重負疚感的結果」。
Part Ⅴ Cloze
67.【解析】[B]考查上下文意思的銜接。本文主要講了現代人都帶著各種面具來掩蓋真實的自己。發現真實的自我，不論是好的還是壞的方面，都使人們感到焦慮，因為人們要決定到底是繼續原來不好的模式，還是達到好的標準。溝通分析是幫助人們了解自己的一種工具。通過分析與他人的溝通和交流，我們可以控制自己和他人交往的行為。本句要表達的是「戴著面具使自己不被人了解」。只有B項 unknown為正確答案。

74.【解析】[B]考查上下文意思的銜接。不論哪種發現都會引起改變。上面提到的兩種發現，任何一個都涉及改變。
75.【解析】[A]考查句子之間的關係。(由於涉及改變)所以產生焦慮。此處是因果關係，所以用therefore。
76.【解析】[D]考查句子之間的關係。然而，這種焦慮可以被看成是一種激動和興奮。轉折關係。上句說到焦慮，是負面的;這句轉折到正面。
77.【解析】[A]考查對上下文的理解。這種激動可能會促使一個人成為勝利者。只有 possibility 符合題意。
78.【解析】[D]詞義辨析題。溝通分析法是一種你可以用來了解自己的工具。instrument指器械;appliance指用具，器具;equipment指裝備，設備;tool指工具，手段。
79.【解析】[A]詞義辨析題。知道自己人生所走的富有戲劇性的道路。course指路線，進程;process 指過程;track指軌跡;direction指方向。

83.【解析】[B]考查上下文意思的銜接。通過分析你與他人的溝通，你可以更清醒地控制自己和他人的交往。溝通分析是使人了解自己的行為，從而進行控制。顯然是更清醒地控制自己。
84.【解析】[B]詞義辨析題。溝通分析是一種實際設計。由文章可知，溝通分析是一種有效的了解自身的方式。desire顯然不合題意; stage階段;step步驟;與題意不符，為錯誤答案。B為正確答案。
85.【解析】[A]詞義辨析題。對以前的決定和行為進行評價。對舊的決定顯然已經無法改變，故B不正確;C和D 均不能搭配，為錯誤答案，只有 evaluate是正確答案。
86.【解析】[D]考查代詞的用法。改變你認為值得改變的東西。what 作decide 的賓語，表示你決定的是什麼。
