本期重點：句子結(jié)構(gòu)不完整

　　比較復(fù)雜的復(fù)合句最容易出現(xiàn)此類錯誤，因為句子較長，缺少了某個成分，如主語、謂語、賓語、連詞等等。

　　考點例析：

　　例1： If his aim is inaccurate and he scores a goal, enjoys S3.____the hunter’s triumph of killing his prey.
　　解析：這是由一個條件狀語從句引導(dǎo)的復(fù)合句。但主句只有謂語動詞enjoys，缺少主語，因此要步上主語。根據(jù)從句的his aim可推斷應(yīng)該加上主語he。

　　例2：Nuclear physicists who interested in the structure of 5._________atoms cannot observe protons, electrons and neutrons directly.
　　解析：如果將who后面的部分作定語從句，那么它絕少謂語，故將who去掉，此時分詞短語interested in直接作定語修飾前面的physicists。或在who后加are，補全定語從句。

　　例3：This alliance guarantees that all leprosy patients, even they S6.______are poor, have a right to the most modern treatment.
　　解析：even是副詞，后面不能直接跟句子，根據(jù)句子的意思，應(yīng)該在even后加if或though。

　　考答案及解析：

　　鞏固與拓展：

　　1. 在performer后加as
　　此處為同級比較，固定結(jié)構(gòu)為as...as...，而原句比較的對象a medical student前缺少連詞as。

　　2. want -> wanting或those后加who
　　for為介詞，后面的賓語時代詞those，不可再跟主謂結(jié)構(gòu)。故將want改為wanting，用現(xiàn)在分詞短語作定語修飾those，或者在want前加who構(gòu)成定語從句修飾those.

　　3. inaugurate后加it

　　4. made后加it
　　句子主語是law，謂語是made，easier是賓語補足語，邏輯賓語是to get a divorce，可見此句缺少形式賓語it.

　　5. fact后加that
　　fact之后的部分是同位語從句，補充說明fact，其引導(dǎo)詞不能省略。

　　綜合訓(xùn)練

　　1. small -> smaller
　　該句后面有than，所以前面應(yīng)該是smaller。

　　2. make -> take
　　take advantage of 為固定搭配，意思為“利用”，與其同樣意思的詞組還有make use of。

　　3.basing -> based
　　base和它的邏輯主語是被動關(guān)系。

　　4. has -> have
　　句子的主語是two US appliance companies, 謂語動詞要用復(fù)數(shù)。

　　5. Neither -> Both
　　根據(jù)文章的中心觀點，這里時說兩種產(chǎn)品都如何。故要用both

　　6. and -> but
　　本句的意思應(yīng)該是：大部分人都是早上煮一壺咖啡 但卻只喝一小杯。并列句前后應(yīng)該是轉(zhuǎn)折關(guān)系。

　　7. spends -> costs
　　spend的主語必須是人，此處主語是物，應(yīng)該用cost表示 “該物花費了多少”。

　　8. maker 后加that或which
　　一個句子在沒有連詞的情況下不能帶有兩個謂語，本句的謂語是makes，而drips和之后的部分應(yīng)該是定語從句修飾coffee maker，又由于先行詞在從句中作主語，所以引導(dǎo)詞不能省略。

　　9. closes前加and
　　在英語中，用逗號連接兩個獨立的主謂結(jié)構(gòu)是不對的，所以要在closes前加and。

　　10. at -> in
　　表示“在...方面”，使用介詞in.
