[例1] The little girl was so tired that she couldn’t go farther.
The little girl was ______ tired ______ go farther.
（一）?? 句型转换的解题应试技巧1．必须弄清原句的句型和意思以及判别改写后的句子是什么句型。 通过分析，我们不难发现，该题是由复合句转换为简单句，可用too…to句型。
根据我们所学过的同义词组，look after sb well相当于take good care of sb. [例2] It took him two hours to do these exercises yesterday.
He ______ two hours ______ these exercises yesterday.
该句的句型是It takes sb sometime to do sth. 英语表达该意思的还有spend…on句型。[例3] I must look after my sister well at home.
I must ______ ______ ______ ______ my sister at home.
很明显，这是两个简单句之间的转换，可用not strong enough来填空。 [例4] They were tired, so they had a rest.
They had a rest ______ they were tired.
该句由并列句转换为复合句，可用because来连接，表示因果关系。[例5] He was too weak to carry the heavy box.
He was ______ ______ ______ to carry the heavy box.
从近年来的考题趋势来看，句型转换从单纯测试语法知识向改变句子结构填空，填词后使句意不变或与要求相符的方向发展。其中许多属于常用句型。可归纳如下：
