2．误：Was it because it snowed last night when you didn’t come？

　正：Was it because it snowed last night that you didn’t come？

　译：你是否因昨晚下雪而没有来？

　析：应将when改为that，因为，原句还原为Because it snowed last night，you didn"t come后，在语法和句意上均成立，故此题是强调句型而非定语从句。

1．误：It was in the kitchen where the fire broke out．

　正：It was in the kitchen that the fire broke out．

　译：大火发生在厨房。

　析：应将where改that，因为原句还原为The fire broke out in the kitchen后，在语法和句意上均成立，故此题是强调句型，而非定语从句。

2．误：I don’t believe the reason why he has given for his being late．

　正：I don’t believe the reason that／which he has given for his being late．

　译：我不相信他所提供的他迟到的原因。

　析：应改why为that或which，因为从句谓语动词has given后缺少宾语，而不是缺少原因状语。

　(七)、误将强调句型当定语从句。如：

1．误：Have you asked her for the reason why may explain her absence？

　正：Have you asked her for the reason that／which may explain her absence？

　译：你是否向他问过可以解释他缺席的原因？

　析：应改why为that或which，因为定语从句缺少主语，而不是少原因状语。

2．误：This is the house where we lived in last year．

　正：This is the house which／that we lived in last year．

　译：这是我们去年住过的那个房子。

　析：应改where为which或that，因为从句谓语动词lived后有介词in，其后少介词宾语，而不是地点状语。

　(六)、在先行词reason后错用关系副词why。如：

1．误：I still remember the day when we spent together．

　正：I still remember the day that／which we spent together．

　译：我仍记得我们在一起度过的日子。

　析：应改when为that或which，因为从句中谓语动词spent是及物动词，其后应跟宾语而不是时间状语。

2．误：I still remember the day on when I first came to Beijing．

　正：I still remember the day when I first came to Beijing．

　或：I still remember the day on which I first came to Beijing．

　译：我仍记得我第一次来到北京那天的情景。

　析：应删去on，因为when在这里的意思是on which，否则介词on就重复了，或把when改为which。

　(五)、在作先行词的时间名词或地点名词后错用了关系代词或关系副词。　

1．误：The house where he lives in needs repairing．

　正：The house where he lives needs repairing．

　或：The house he lives in needs repairing．

　译：他住的房子需要修理。

　析：应保留where，删去从句中的in，因为关系副词where在从句中作地点状语，in属多余。或删去关系副词where，因为where在这里的意思是in which，否则介词in就重复了。

2．误：The key opens the bike is missing．

　正：The key that／which opens the bike is missing．

　译：开这辆自行车的钥匙不见了。

　析：应加上关系代词that或which，因为从句少主语，且主语不能省略。

　(四)、定语从句中加了多余的关系副词或介词。如：

1．误：Children eat a lot of sugar often have bad teeth．

　正：Children who that eat a lot of sugar often have bad teeth．

　译：吃糖多的孩子往往牙齿不好。

　析：应加上关系代词who或that，因为从句少主语，且主语不能省略。
