1. 不定型工to后面接原形動詞
例題分析
(1) Astronauts circling the Earth may get to seen sixteen sunrises and sixteen sunsets every day.
[答案] 動詞不定型式的標志to后面應(yīng)接動詞原形see。
(2) Using their bills as needles, tailorbirds sew large leaves together with plant fiber to forming their nests.

(3) The poetry of E.E Cummings illustrates the way in which some poets bend graminastical rules as they strive to expression their insights.
[答案] 動詞不定式to后面只能接原形動詞，不能接名詞。
(4) The dromedary camel is raised especially to racing.
[答案] 這是一個非常簡單的動詞不定式錯誤形式的考題。Racing應(yīng)改為race,與to組成不定式。
2. 動詞不定式作目的狀語
解題要點 不定式結(jié)構(gòu)在句中可以作多種成分，目的狀語則是常考到的形式。
例題分析
(1) A fuel is a substance used ------- light, heat .or energy .
(A) generating (B) generates (C) to generate (D) it is generating

(3) ------- time and labor, cartoonists generally draw the hands of their characters with only three fingers and a thumb.
(A) Saved (B) Saves (C) To save (D) The saving (91.5)
[答案] C 此句與上面例題結(jié)構(gòu)相同。不定式作目的狀語，且放在句首表示強調(diào)。
3. 動名詞的正確用法
解題要點 有關(guān)名詞的考題并不很多，但有一個常出現(xiàn)的題型；介詞后面的動詞一定要用動名詞形式，作介詞的賓語。
例題分析
(1) Microwave cooking can be accurately described as the first absolutely new method of prepare food since the discovery of fire.
[答案] 介詞of后面應(yīng)接動名詞形式，即of preparing。
(2) Most crickets have two pairs of fully developed wings, and muscular hind legs for jump.

(3) Because it is a healthful way to exercise derobic dancing is considered an excellent method for release tension.

(4) The Cubist movement in art was reaction against traditional methods of portray reality.
[答案] 動詞原形portray應(yīng)改為動名詞portraying即作前面介詞of的賓語，自身又帶賓語reality。
