【題目】Considered an all-around inventor and often mentioned in the same sentence【1】Thomas Edison,Eli Whitney is best known【2】the invention of the cotton gin（軋棉機(jī)）in 1793 or 1794.Simply put,a cotton gin is a machine that 【3】(use) to pull cotton fibers from the cotton seed（種子）.The cotton gin【4】(be) a pioneering invention early in the southern United States,and it had【5】great positive effect on the economies of the southern states in the US.The cotton gin also had an【6】(equal) important effect on slavery in this country.Before Whitney's cotton gin,【7】(raise) cotton required much labor and only a few【8】(field) could favourably raise cotton.The cotton gin changed cotton into a widespread,money making and less labor-intensive（勞動密集型的）crop,leading to the rise of cotton【9】 (produce) in the Deep South.It is different to draw a conclusion with absolute certainty that the cotton gin directly 【10】(lead) to an increase in slavery,but the cotton gin clearly was a major factor contributing to slavery issues in the South.

【答案】

【1】as

【2】for

【3】is used

【4】was

【5】a

【6】equally

【7】raising/to raise

【8】fields

【9】production

【10】led

【解析】本文主要說了Eli Whitney發(fā)明的軋棉機(jī)給予了人們很大的幫助，并且對此進(jìn)行了詳細(xì)的說明。

【1】本句意為想一些比較有名并且經(jīng)常會被提到的發(fā)明家，緊接著后面舉例了愛迪生，因為是一個名詞，所以舉例時應(yīng)該用介詞as

【2】本句意為Eli Whitney是因為他軋棉機(jī)的發(fā)明而被眾所周知的，be known for是固定搭配的詞組，意為“由于…而出名”。故填for

【3】本句意為軋棉機(jī)是用來從棉花種子中拉取棉花纖維的機(jī)器。That是用來指代前面的軋棉機(jī)的，后面是說軋棉機(jī)的用法，是“被使用于…”的意思，用be+done的形式，故填is used

【4】本句意為軋棉機(jī)早期在美國南部地區(qū)是一個開拓性的發(fā)明。這里主語是軋棉機(jī)，賓語是開拓性的發(fā)明，后面的early可以得知是過去的事情。故填was

【5】這里是說軋棉機(jī)有一個積極的優(yōu)點(diǎn)。“great positive effect”是名詞，前面需要定冠詞。故填a

【6】本句意為軋棉機(jī)有一個同樣重要的原因。equal用來修飾后面的important，副詞用來修飾形容詞，故填equally

【7】這里是說Whitney的軋棉機(jī)有什么樣的作用，主語是軋棉機(jī)，從句表目的時可以用不定式或現(xiàn)在分詞。故填raising/to raise

【8】本句意為這里只有一些可以種棉花的土地。A few是“一些”的意思，后面可以加可數(shù)名詞，故填fields

【9】在這里是指帶動了棉花產(chǎn)品的上升，因此要將produce變成名詞形式。故填production

【10】這里主要是指軋棉機(jī)在過去帶來的一系列好處，是過去發(fā)生的事情，因此動詞要用一般過去時。故填led
