　　教材分析（教学要求）重点1   milliona hundred                   100a thousand                  1,000ten thousand                10,000a 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.)
