4. According to paragraph 2, which of the following is true about the small mammals in the rain forest? (A) They have body shapes that are adapted to life in the canopy. (B) They prefer the temperature and climate of the canopy to that of other environments. (C) They have difficulty with the changing conditions in the canopy. (D) They use the trees of the canopy for shelter from heat and cold. 5. In discussing animal size in paragraph 3, the author indicates that (A) small animals require proportionately more food than larger animals do (B) a large animal’s size is an advantage in obtaining food in the canopy (C) small animals are often attacked by large animals in the rain forest (D) small animals and large animals are equally adept at obtaining food in the canopy 首先要确认一下这篇文章共有几段。从排版上看是3段，但第7题的题目是‘7. According to paragraph 4, what makes jumping from one tree crown to another difficult for small mammals?’，所以这篇文章是不是有4段。而且，第4题的答案为D：They use the trees of the canopy for shelter from heat and cold.而这句话是出现在第一段中的，所以我猜测是不是第一段实际上是2段？ 另外，第5题的答案为A，但我怎么不能从文中找到对应文字呢？我觉得应该是B.亦即第3段（排版中为第2段）的中心思想。
20. What does paragraph 1 mainly discuss? (A) Design elements in the Art Nouveau style (B) The popularity of the Art Nouveau style (C) Production techniques for art glass (D) Color combinations typical of the Art Nouveau style the answer is B. 但我觉得整个第一节通篇都是将的elements，如characterized by…,an eclectic one, bringing together…,iridescent furface等，没有提及popularity.所以我选A.
Paragraph 1: The end of the nineteenth century and the early years of the twentieth century were Marked by the development of an international Art Nouveau style, characterized by sinuous Lines, floral and vegetable motifs, and soft evanescent coloration. The Art Nouveau style Line was an eclectic one, bringing together elements of Japanese art, motifs of ancient cultures, (5) and natural forms. The glass objects of this style were elegant in outline, although often deliberately distorted, with pale or iridescent surfaces. A favored device of the style was to imitate the iridescent surface seen on ancient glass that had been buried. Much of the Art Nouveau glass produced during the years of its greatest popularity had been generically Termed “art glass.” Art glass was intended for decorative purposes and relied for its effect (10) pon carefully chosen color combinations and innovative techniques.
38.The term “vicious cycle” in lines 21-22 refers to the (A) movement pattern of surge glaciers (B) effect surge glaciers could have on the temperature of tropical areas (C) effect that repeated rising sea levels might have on glacial ice (D) constant threat surge glaciers could pose to the Gulf of Alaska The answer is A. But I choose A.
About 20 similar glaciers around the Gulf of Alaska are heading toward the sea. If enough surge glaciers reach the ocean and raise sea levels, West Antarctic ice shelves could rise off the seafloor and become adrift. A flood of ice would then surge into the Southern (20) Sea. With the continued rise in sea level, more ice would plunge into the ocean, causing sea levels to rise even highter, which in turn would release more ice and set in motion a vicious cycle. The additional sea ice floating toward the tropics would increase Earth’s albedo and lower global temperatures, perhaps enough to initiate a new ice age. This situation appears to have occurred at the end of the last warm interglacial (the time between glacations), (25) called the Sangamon, when sea ice cooled the ocean dramatically, spawning the beginning of the Ice Age.
43. In mentioning “natural leaders” in lines 8-9, the author is making the point that (A) few people qualify as “natural leaders” (B) there is no proof that “natural leaders” exist (C) “natural leaders’ are easily accepted by the members of a social group (D) “natural leaders” share a similar set of characterisitics the answer is B. not A..why？ “natural leaders’ means “天生的“
