PAGE  PAGE 5 写作基本句型训练(四) 学习内容：强调句型：it+be+强调部分+ that+其它 Only+状语→引起的倒装 until….. not until… 句型 教学步骤： Step 1. 学习并翻译下面的句子： 1. It was him that we met at the school gate. 2. Only in this way can we learn English well. 3. You are to stay here until/till your mother comes back. 4. I didn’t go downstairs until the window had to be shut. 思考：句子①和②分别是什么句式：____________________, __________________ Step 2. 学习难点： 1. Only+状语（副词，介词短语，状从）置于句首引起的倒装 Only in this way can we learn English well.（we can learn English well in this way） 介短 Only then did I realize my mistakes. (I realize my mistakes then.) 副 Only when he returned did we find out the truth. (when he returned did we find out the truth.) 状从（主句倒装从句不倒） 注意： = 1 \* GB3 ① Only+状语（副词，介词短语，状从）置于句首引起的倒装属于部分倒装，即：把句中的助动词、情态动词置于主语的前面，如句 = 1 \* GB3 ①can we; 当原句中没有或你想表达的句子中没有助动词或情态动词时，则需要另添加助动词（do/does/did）来表示倒装，如句 = 2 \* GB3 ② did I，句 = 3 \* GB3 ③ did we. 添加的助动词的时态必须与原句的时态保持一致。  = 2 \* GB3 ② only修饰主语时句子不倒装。 判断下列句子的正误： Only after the war learned he the sad news. Only after the war he learned the sad news. Only after the war did he learned the sad news. Only can he answer the question. Only he answer the question. Only when did he return did we find out the truth. 2. 强调句型：it+be+强调部分+ that+其它 We met him at the school gate. It was him that we met at the school gate. 强调部分 其它 It was at the school gate that we met him. 强调部分 其它 注意：如何判断强调句/写出正确的强调句：当把句中的It is/was ….that 删去，剩下的部分仍能组成一个完整的句子。 . It was him that we met at the school gate.(√) It is clear that not all the boys like football.(×) 形式主语 It was in 1919 that he was born. (√) It was 1919 that he was born. （×）定从 3. not until….句型：直到….才 The villagers didn’t realize how serious the pollution was until the fish died in the river. 注意：①not …until… 句型的前半部分是需要否定形式的（即通过助动词、情态动词：don’t/doesn’t/didn’t/can’t/haven’t/won’t….来否定）所选用的助动词的时态与原句保持一致。 ②此句型的后半句（从句部分）需要用一般现在时表示将来。 Jane won’
