题目内容
6.I think it quite essential that your child(should)learn(learn) a foreign language at school.分析 我认为孩子在学校学习一门外语是相当有必要的.
解答 答案:(should)learn
解析:分析句子结构可知it在句中作形式宾语,that引导的是宾语从句,essential"必要的"作宾语补足语.当necessary,important,essential,imperative,urgent,preferable,vital,advisable这些形容词在句中作表语或者是补足语时,其后面的从句该使用虚拟语气(及从句中的谓语动词使用"should+动词原形",其中should可以省略).综上,本题答案为:(should)learn.
点评 本题考查单词填空,做此类题目时一定要仔细分析句子结构,根据所给提示词从语法、句意等方面确定所填词的正确形式.
