句型梳理
1.（教材P38）What if the only way of getting news from faraway friends was writing letters that took ages to be delivered
如果从远方朋友那里得到消息的唯一途径就是写信,而且要花很长时间才能送到,那该怎么办
What if... 如果……怎么办 /要是……会怎么样
What if… 句型其实是包含了if引导的条件状语从句、但省略了主句内容的，相当于“What would happen if...”。由于if引导的从句提出的是一个假设，在从句中根据不同的情况使用陈述语气（一般现在时）或是虚拟语气（一般过时时）都是可以的。
(1)用于提出假设时，意思是“假若……”“假若……怎么办”“要是……将会怎么样”，其后句子可用陈述语气（用一般现在时），也可用虚拟语气（用一般过去时或should+动词原形）。
What if she finds out that you’ve lost her book
如果她发现你把她的书丢了怎么办
But what if somebody decides to break the rules
但是如果有人决定打破这些规则呢？
What if it rains when we can’t get under shelter
假若下起雨来，我们又没处避雨可怎么办
(2) 表示邀请或建议意思是“如果……怎么样？”“如果……如何？”。
What if you join us for lunch
同我们一起吃午饭怎么样？
What if we moved the sofa over here Would that look better
要是我们把沙发挪到这边来会怎么样？看上去会不会好一些？
(3) 表示不重要，此时通常与so连用，意为“就算……那又怎样？”
So what if we're a little late
就算我们迟到一会儿那又怎样？
So what if nobody else agrees with me
就算没有一个人赞成我的意见，那又怎么样？
2.（教材P39）Although technology has changed the way we acquire friends...
尽管技术已经改变了我们结交朋友的方式……
the way(+ that/in which)+ 定语从句
the way(方式,方法)作先行词后接定语从句时有以下三种情况:
(1)关系词在从句中作状语,关系词用 that, in which 或省略
(2)关系词在从句中作主语,关系词用 that 或 which
(3)关系词在从句中作宾语,关系词用 that, which 或省略
I don't like the way (that/in which) you speak to your mother.
我不喜欢你同你母亲说话的方式。
