關(guān)于托福句子插入題大家肯定都已經(jīng)很熟悉了?；径际堑箶?shù)第二題，題目會(huì)在段落中安排四個(gè)黑色的小方塊，再給我們一個(gè)新句子，問我們新句子放在哪個(gè)位置比較好。

　　這樣看似簡(jiǎn)單戳一戳就能搞定的題目其實(shí)背后的要求也比較高。它不僅需要我們了解這段落內(nèi)部的邏輯，還要了解句與句之間的語(yǔ)法聯(lián)系。

　　技巧一：代詞鎖定法

　　這是我們拿到句子插入題的第一步，先看看新句子里面有無代詞，如果有的話可以根據(jù)代詞+名詞的結(jié)構(gòu)，判斷出前文也會(huì)提到這個(gè)名詞，然后就回到四個(gè)黑色小方塊前面的句子搜索，哪個(gè)句子有這個(gè)名詞就選擇哪個(gè)小方塊。

　　例題一：

　　Paragraph 5: These forces were the rapidly expanding electronics and telecommunications companies that were developing and linking telephone and wireless technologies in the 1920s. In the United States, they included such firms as American Telephone and Telegraph, General Electric, and Westinghouse. They were interested in all forms of sound technology and all potential avenues for commercial exploitation. Their competition and collaboration were creating the broadcasting industry in the United States, beginning with the introduction of commercial radio programming in the early 1920s. ■With financial assets considerably greater than those in the motion picture industry, and perhaps a wider vision of the relationships among entertainment and communications media, they revitalized research into recording sound for motion pictures.

　　上面這個(gè)例題一下給了我們兩段，如果我們想要把段落都看完再來選答案肯定會(huì)花不少時(shí)間，但是如果我們用上代詞的技巧就能非常簡(jiǎn)單快速地把題目做出來了。

　　新句子中有this research這個(gè)代詞+名詞的結(jié)構(gòu)，說明在這個(gè)新句子的前面會(huì)說到一個(gè)research。

　　技巧二：句間邏輯分析法

　　當(dāng)然并不是每個(gè)題目都像上面那種情況一樣善良，我們也會(huì)碰到有代詞但用不上或者壓根沒有代詞的情況。

　　例題二：

　　Leatherbacks keep their body heat in three different ways. The first, and simplest, is size. The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape. An adult leatherback is twice the size of the biggest cheloniid sea turtles and will therefore take longer to cool off. Maintaining a high body temperature through sheer bulk is called gigantothermy. ■It works for elephants, for whales, and, perhaps, it worked for many of the larger dinosaurs. ■It apparently works, in a smaller way, for some other sea turtles. ■Large loggerhead and green turtles can maintain their body temperature at a degree or two above that of the surrounding water, and gigantothermy is probably the way they do it. ■Muscular activity helps, too, and an actively swimming green turtle may be 7°C (12.6°F) warmer than the waters it swims through.

　　這道題看似可以用我們的老方法代詞來做，但操作起來就會(huì)發(fā)現(xiàn)these animals除了可以幫助我們排除掉第一個(gè)小方塊，其實(shí)不能直接幫助我們選出答案，因?yàn)楹笕齻€(gè)小方塊前面的句子里都有不同的動(dòng)物。

　　技巧三：原文聯(lián)系排除法

　　可能會(huì)有刷題比較多的同學(xué)提問，如果新句子中既沒有代詞也沒有邏輯，那要怎么辦呢?不要慌張，如果覺得新句子給到的線索不太多，也可以結(jié)合小方塊前后原文本身的聯(lián)系來做排除法。一起來看下面的例題吧!

　　例題三：

　　Speculation on the origin of these Pacific islanders began as soon as outsiders encountered them, in the absence of solid linguistic, archaeological, and biological data, many fanciful and mutually exclusive theories were devised. Pacific islanders are variously thought to have come from North America, South America, Egypt, Israel, and India, as well as Southeast Asia. ■Many older theories implicitly deprecated the navigational abilities and overall cultural creativity of the Pacific islanders. ■For example, British anthropologists G. Elliot Smith and W. J. Perry assumed that only Egyptians would have been skilled enough to navigate and colonize the Pacific. ■They inferred that the Egyptians even crossed the Pacific to found the great civilizations of the New World (North and South America). ■In 1947 Norwegian adventurer Thor Heyerdahl drifted on a balsa-log raft westward with the winds and currents across the Pacific from South America to prove his theory that Pacific islanders were Native Americans (also called American Indians). Later Heyerdahl suggested that the Pacific was peopled by three migrations: by Native Americans from the Pacific Northwest of North America drifting to Hawaii, by Peruvians drifting to Easter Island, and by Melanesians. In 1969 he crossed the Atlantic in an Egyptian-style reed boat to prove Egyptian influences in the Americas. Contrary to these theorists, the overwhelming evidence of physical anthropology, linguistics, and archaeology shows that the Pacific islanders came from Southeast Asia and were skilled enough as navigators to sail against the prevailing winds and currents.

　　我們來看第一個(gè)小方塊，后面說到了Many older theories很多更早的理論，而我們這個(gè)新句子說的是之后的理論，在沒有任何展開的情況下是沒辦法直接連上以前的理論的，所以第一個(gè)選項(xiàng)pass。
