托福閱讀的句子簡(jiǎn)化題答題方法

托福閱讀重點(diǎn)考察考生的閱讀理解和對(duì)于信息提取的能力，是為將來進(jìn)一步的學(xué)術(shù)期刊的閱讀和學(xué)術(shù)研究打下基礎(chǔ)。閱讀文章中出現(xiàn)的長(zhǎng)難句常是考生閱讀中 遇到的一大難點(diǎn)，而托福閱讀十種題型中的句子簡(jiǎn)化題更是針對(duì)文章中的長(zhǎng)難句進(jìn)行了重點(diǎn)考察。

At one time, the animals present in these fossil beds were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose in the early Cambrian period and disappeared before the end of the period, leaving no descendants in modern animal groups.

The animals found in the Tommotian fossil bed were once thought to belong to a variety of modern animal groups, but now they are thought to have descended from a single group.

Animals in the Tommotian fossil beds were initially assigned to modern animal groups but are now thought to belong to groups that emerged and died out during the Cambrian period.

Though at first they thought otherwise, paleontologists now agree that the animals in the Tommotian have body forms from which modern animals have descended.

It is unclear whether the Tommotian fossils from the early Cambrian period represent unique body forms or whether they should be assigned to various modern animal groups.

解題：

1看原句是否有邏輯關(guān)系詞

瀏覽原句，發(fā)現(xiàn)有but這個(gè)表轉(zhuǎn)折的邏輯詞。

該句句意：曾經(jīng)，存在于這些化石中的動(dòng)物被規(guī)定為現(xiàn)代動(dòng)物種群，但是，如今，考古生物學(xué)家認(rèn)為所有的Tommotian化石代表獨(dú)有的個(gè)體，它們起源于寒武紀(jì)初期，并消失于該紀(jì)元的末期，導(dǎo)致該動(dòng)物種群在現(xiàn)代動(dòng)物種群中沒有留下后代。

2看選項(xiàng)表達(dá)轉(zhuǎn)折關(guān)系的邏輯詞

A選項(xiàng)有but
　　B選項(xiàng)有but
　　C選項(xiàng)是although表讓步轉(zhuǎn)折
　　D選項(xiàng)是沒有邏輯關(guān)系的復(fù)合句

D選項(xiàng)首先排除。

3細(xì)節(jié)對(duì)比解題

在A，B，C三選項(xiàng)中，

A選項(xiàng)句意：在Tommotian化石床中發(fā)現(xiàn)的動(dòng)物曾被認(rèn)為屬于現(xiàn)代動(dòng)物種群，但是現(xiàn)在，它們被認(rèn)為是單一動(dòng)物種群的后代。

顯然，但是后的內(nèi)容與原句但是后的內(nèi)容完全不符。

B選項(xiàng)句意：在Tommotian化石床中發(fā)現(xiàn)的動(dòng)物最初被規(guī)定為現(xiàn)代動(dòng)物種群，但是現(xiàn)在被認(rèn)為屬于出現(xiàn)于寒武紀(jì)初期，滅絕于寒武紀(jì)末期的動(dòng)物種群。

B選項(xiàng)但是前后的內(nèi)容和原句但是前后的內(nèi)容完全吻合。

看到這里就把B選了吧，其它選項(xiàng)看了是浪費(fèi)時(shí)間，況且是胡編亂造的，影響對(duì)文章的理解。
