突破2个高考句型
(教材P8)...，“it is clear that we are going to see a huge growth in shopping on the Internet.”……“很显然，我们将会看到网上购物的巨大增长。”
本句句型为：It is clear that...句型。在这一句型中，it为形式主语，that从句为真正的主语。
(1)常用于这种结构的形容词有：clear，obvious，certain，important，possible，natural，interesting，likely，unusual等。
(2)在It is necessary/important/strange/surprising/
unthinkable/unbelievable/incredible＋that...中，从句中的谓语动词常用“should＋动词原形”，should可省略。

②It is important that we(should)discuss(discuss) the plan.重要的是我们该讨论这个计划。
[名师点津] 在以上句型中，如果从句内容只是简单地陈述事实，谓语动词用陈述语气；如果从句内容并不是陈述事实，而是表达某种强烈的情感(要求、建议、命令、责备、惋惜、吃惊等)，谓语动词用虚拟语气，即“(should＋)do”形式 (教材P8)Some experts see our future in virtual reality—the use of computers with sounds and pictures that make you feel as if you are in a real situation.有些专家看到虚拟现实的未来——(虚拟现实)是计算机通过声音和图像模拟现实，以使人感到仿佛置身于一个真实的空间。
as if(＝as though)意为“仿佛；好像；似乎”，常用在be，look，seem，sound，smell，feel等系动词的后面引导表语从句。
(1)省略：如果as if/though引导的方式状语从句为主系表结构且其主语与主句主语一致，则可省略其中的主语和系动词。 (2)语气：如果as if/though引导的从句表示实现的可能性很小或与事实相反，则用虚拟语教育配套资料K12

气；如果实现的可能性较大，则用陈述语气。 ①It looks as if it's going to rain. 天看起来要下雨了。
