     (1) 主句为一般将来时，从句用一般现在时表示将来。例如： He will come to my home as soon as he gets to Beijing. 他一到北京就来我家。

　　2. Finally, a god was so moved by Yu Gong that he sent two gods to take the mountains away.so…that…引导结果状语从句，意为“如此……以至于……”，此句型中，so是副词，常用来修饰形容词或副词。常用句型为：主语+谓语+ so+ adj./adv. + that从句。例如： Our teacher is so kind that all of us like him. 我们的老师是如此好心以至于我们都喜欢他。 He runs so fast that nobody in my class can catch up with him. 他跑得那么快，我们班没有人能追上他。

     【拓展】“如此……以至于……”归纳：

    (1) so + 形容词 + a/an + 单数名词 + that从句 = such + a/an + 形容词 + 单数名词+ that从句。例如： It was so fine a day yesterday that we all went out for a picnic. = It was such a fine day yesterday that we all went out for a picnic. 昨天天气很好，我们都出去野餐了。

    (2) such + 形容词 + 复数名词/不可数名词 + that从句。例如： They are such good students that the teacher likes them. 他们都是很好的学生，老师喜欢他们。 It was such fine weather yesterday that we went swimming. 昨天天气很好，我们去游泳了。

    (3)当that前的名词有表示数量多少的many, much, few, little等修饰时，只能用so，不能用such。例如： There was so much noise outside that we couldn’t hear the teacher. 外面嘈杂声很大，以致我们不能听到老师的话。 He had so many falls that he was black and blue all over. 他跌了这么多的跤，以致全身青一块、紫一块的。

　　3. It doesn’t seem very possible to move a mountain.seem此处作连系动词，意为“似乎;好像”，后跟形容词作表语。可以和seem to be相互转换。例如： He seems very angry. = He seems to be very angry. 他好像非常生气。

   【拓展】(1) “主语 + seem + (to be) +表语”，表语多为名词或形容词，以说明主语的特征或状态。例如： Tom seems (to be) a very clever boy. Tom 看上去是一个非常聪明的男孩。 Mr. Black seemed to be quite happy. Black先生好像十分快乐。

               (2) “主语 + seem + 不定式”，此句型中，seem与不定式一起构成复合谓语。例如： Mrs. Green doesn’t seem to like the idea. 格林夫人似乎不太喜欢这个主意。 The children seemed to be eating something in the room. 孩子们好像正在房间里吃东西呢。

               (3) “It seems + that从句”，其中it是形式主语，that引导主语从句。例如： It seems that no one knows what has happened in the park. 似乎没有人知道在公园里发生了什么事。 It seems to me that Mr. Brown will not come again. 在我看来布朗先生不会再来了。

               (4) “There + seem to be + 名词”，to be可省略，seem的单复数要由后面的名词决定。例如： There doesn’t seem to be much hope of our beating that team. 看来我们战胜那个队没有多大希望。 There seems no need to wait longer. 看来没有再等的必要了。

　　4. ...what’s possible unless you try to make it happen.unless是连词，引导条件状语从句，意为“除非……;如果不……;除了……”，常引导一个否定意义的真实条件句，有时也可引导非真实条件句。unless引导的条件状语从句中的谓语动词常用一般现在时代替一般将来时。主要用于下列情况：

     (1) 主句为肯定句： You will miss the bus unless you hurry up. 你要不快点就会错过班车。 You’ll fail in chemistry again unless you work harder. 如果你不再加把劲，你化学考试还会不及格。

     (2) 主句为否定句： One can’t learn a foreign language unless he studies hard. 不下苦功夫是学不好外语的。 I will not go unless I hear from him. 如果我不收到他的来信，我就不去。
