It was what she had waited almost 20 years for that made him so happy. 是他差不多等了20年的  東西讓他感到如此幸福。   恩恩，老師您好  我想問一下這句是強調(diào)句型嗎？

It was what she had waited almost 20 years for.

這句話沒有問題.這里it指代上文所提到的某個情況.

這就是她等了快20年想得到的.

Nearby were two canoes in which they had come to the island.  該句 中，定語從句的原句不就是，They had come to the island by two canoes .  這不是很奇怪么？因為by + 交通工具，這個交通工具都是用的原型啊，比如，by air,  by boat ,  by  bus  等。

而且，強調(diào)句中的that 可以省略的嗎？我在網(wǎng)上查了，貌似不能啊。
