Answer 1

分析 To my surprise，he was throwing rubbish into the dustbin when I walked into the house．

解答 答案：To my surprise，he was throwing rubbish into the dustbin when I walked into the house．令人驚訝的用to one's surprise，這里是讓我吃驚的，用my，故to my surprise．這里是說過去的事情，故用過去時，當(dāng)我走進(jìn)房子的時候用when引導(dǎo)的時間狀語從句，走進(jìn)房子用walk into the house，故when I walked into the house．他正往垃圾桶里扔垃圾，過去某個時間正在發(fā)生的動作，用過去進(jìn)行時was/were+doing，主語是三單he，故選was，把…扔進(jìn)…用throw…into…，故throw rubbish into the dustbin，故he was throwing rubbish into the dustbin，故答案是To my surprise，he was throwing rubbish into the dustbin when I walked into the house．

點評 這里是一個when引導(dǎo)的時間狀語從句的表達(dá)，注意時態(tài)的分析．
