教材分析（教学要求）‎ 重点1 million a hundred 100‎ a thousand 1,000‎ ten thousand 10,000‎ a million 1,000,000‎ 重点2 -if句 上个学期，我们曾经学过由if 引导的句子，你还记得吗？对了，“ I’ll not go to the zoo if it rains tomorrow. ( 假如明天下雨，我就不去动物园。) You can come to the party if you don’t wear jeans.（ 如果你不穿牛仔裤，你就能来舞会。）” 这个学期又在本单元见到了似曾相识的同样由if引导的句子，比如：“If I won the lottery, I would give it to medical research. （ 假如我赢了彩票的话，我就捐给医学研究。） If I were you, I would wear jeans and T-shirt.（ 如果我是你，我就穿牛仔裤和T恤。）”‎ 这两个单元学到的句子都是由if引导的。那么，它们有什么区别呢？‎ 对了，分两种情况：‎ ‎1．something may possible happen ‎ 某事发生的可能性较大。‎ 这种情况，有个十三字口诀：“主将从现，主过将从过，主现从现”。即主句是一般将来时，从句用一般现在时；主句用过去将来时，从句用一般过去时；当主句中有can/can’t的话，则从句用一般现在时。例如：‎ If he has time, he will come tomorrow.‎ If she finishes early, she can come back early.‎ If you don’t do homework, the teacher will scold you.‎ ‎2．it is just imaginary, and nothing will happen 某事只是想象的，并不会发生，或者发生的可能性很小。则要用我们常说的虚拟语气。例如：‎ If he were kind, he would help me with it. (He isn’t.)‎ If I had more money, I would buy all of them. (I don’t.)‎ If he were generous, he would give us a good treat. (He isn’t.)‎ If you were tired, you would find a good job.
