在英语新教材中，这样的句式应用得也比较广泛。
如：Can I help you／May I help you／What can I do for you（我能帮你吗）应要求学生充分掌握。
The artist spent two hours drawing a horse．／It took the artist two hours to draw a horse．Shall we go to the zoo／Let's go to the zoo，shall weWhat's the weather like today／How's the weather today7.Don't open the door，will you（2002盐城市）Will you please ________ the door ________8.How many people live in France（2002厦门市）________ ________ the population of France9.We spent twenty minutes cleaning the room yesterday．It ________ ________ twenty minutes ________ ________ the roomyesterday．【类型四】运用感叹句的两种句式进行转换。

【解题要领】这两种时态是针对一般过去时与现在完成时而言的。
一般过去时应表述发生在过去某一时间的动作，惟此，才可能转为现在完成时，并后跟一段时间，但应特别注意动词是否属于延续性动词，如果为非延续性动词，则需将其改为延续性动词或延续性状态。
这样的动词主要有：begin ／start—be on；come—be here；leave—be away（from）；buy—have；borrow—keep；die—be dead；return—be back；marry—be married；fall asleep ／go to sleep—be asleep；open—be open；close—be closed；catch a cold—have a cold；join the League ／Party—be in the League ／Party（be a League ／Party member）；join the army—be in the army ／be a soldier；arrive in ／at—be in ／at；get up—be up，等等。

so．．．that．．．引导的结果状语从句有两种情况：1）表示肯定的结果，可与“enough to”结构互换；2）表示否定的结果，它既可以与“too．．．to”结构互换，也可以改为“not＋adj．／adv．＋enough to”。
（注：此时的形容词或副词应为上句的反义词。
）注意：“so．．that．．”结构前后主语不一致时，应在enough 或too ＋adj．后面加for sb．I hope that I will visit the moon some day．/ I hope to visit the moon some day．He showed me how he used a computer．/ He showed me how to use acomputer．The room is so large that it can hold 1，000 people．/ The room is large enough to hold 1，000 people．He is so young that he can't go to school．/ He is too young to go to school．/ He isn't old enough to go to school．15.They can hardly decide what they will do next．_______ _______ for them to decide what _______ _______ next．16.The foreigners want to know how they can learn Chinese Kongfu well．The foreigners want to know _______ _______ learnChinese Kongfu well．17.He is too young to go to school．He isn't _______ _______ to go to school．18.She was so weak that she couldn't take care of her baby．She was_______ weak _______ take care of her baby．［类型七］运用介词短语改写。
