2014届高考英语 重点词汇归纳 祈使句+and+陈述句复习剖析

祈使句+and+陈述句1、promise sb. to do sth.=allow/permit sb. to do sth.=允许/答应某人做某分析：二者的汉语意思一样。但用法有区别，请看例子：My father promised me to give up smoking. 我爸爸答应我戒烟。（是“爸爸”戒烟，而不是“我”戒烟。即：动词不定式是主语发出的动作）My father doesn’t permit/allow me to smoke. 我爸爸不允许我抽烟。在此结构中，动词不定式是宾语发出的动作。另外，两者的结构区别如下： promise to do sth.（后跟不定式）allow/permit doing sth.（后跟动名词）例：I promised to help him with his English.Drinking wine is not allowed /permitted in our school.2、provide vt.提供；供给①provide n. for ②provide n. withThe government provided food and houses for those who were homeless.政府给无家可归的人提供食宿。The school provides the students with textbooks.或：The school provides textbooks for the students.学校为学生提供课本。3、祈使句+and+陈述句1）这种结构可以替换成“条件句+陈述句”。如：Work hard,and you’ll be successful in time./If you work hard,you will be successful in time.只要你努力，一定会成功。注意：祈使句后 and 可替换成 then.2）祈使句+or+否定陈述句=否定条件句+否定陈述句。如：Get ready or you won’t pass the test./ If you don’t get ready,you won’t pass the test.做好准备，要不你小测验不会及格的。注意：祈使句后的 or 可替换成 otherwise.
