题目内容
10.直到他此次考试不及格,他才意识到词汇学习包括拼写单词以及学会正确的使用词汇表达自己的观点.(Not until…)Not until he failed in the exam,did he realize learning vocabulary involved spelling and correctly using them to express his opinions..
分析 Not until he failed in the exam,did he realize learning vocabulary involved spelling and correctly using them to express his opinions.
解答 Not until he failed in the exam,did he realize learning vocabulary involved spelling and correctly using them to express his opinions.
根据句意"直到他此次考试不及格,他才意识到"可知,表达的是过去的事实,所以用一般过去时.
根据后面括号中的提示词可知,使用not until位于句首引起部分倒装的句型,后面的不定式to express his opinions作目的状语.express one's opinions表达某人的观点.
点评 熟练使用not until位于句首引起部分倒装的这一句型,结构一定要掌握清楚,遵从"主倒从不倒"的原则,即倒装的是句子的主句部分,而not until引导的时间状语从句不需要倒装.
