The World's Cultural Heritage1. To learn how to use the subjunctive
2. To learn how to use adverbials of place, condition and concession. 定义: 用来表示说的话不是事实, 或者是不可能发生的情况, 而是一 种愿望、建议、假设的语气叫虚拟语气。虚拟语气用于宾语从句、主语从句、表语从句或同位语从句中，构成往往是由“should+动词原形”构成的that从句。一、虚拟语气在宾语从句中的使用1. 表示要求, 命令, 建议的虚拟语气。常见动词: 一个坚持, 两个命令, 三个建
议，四个要求。
一坚持：insist
二命令：order, command
三建议：advise, suggest, recommend
四要求：require, request, demand, desire
should + 动词原形，或者将should省略。e.g. The driver demanded that all the
passengers ______________ (show) their
tickets to him.?
Lucy insisted that she ___________ (go)
abroad. (should) show(should) gosuggest that...中的that从句并非总用虚拟语气。表示“建议做某事”，用虚拟语气；表示“表明，暗示……”,则不用虚拟语气。
insist表示“坚持某种说法”时，后面的从句不用虚拟语气。
e.g. Her red face suggests that she is a little
shy. 她红红的脸蛋暗示她有点儿害羞。
He insisted that he was right.
他坚持声称他是对的。Jane's pale face suggested that _____________, and her parents suggested that she ____________ a medical examination.

e.g. You treat the elderly as if / though
they were your parents.
He behaved as if / though nothing
had happened.2.?在It is (high / about) time后的定语从句中，谓语动词用虚拟语气，多用过去式，意为“该干……了”。
e.g. It is high time that we took measures
to protect these endangered animals.
It is time that you made up your
mind.3. 在if only（但愿，要是……就好了）引导的感叹句中，谓语动词常用虚拟语气，其谓语动词形式与wish后宾语从句的谓语动词用法相同。
