Non-restrictive attributive clause (非限制性定语从句) is an adjective clause set off from the main clause by commas. It provides added, but not essential information and does not restrict or limit the noun it modifies.e.g.I finally felt comfortable within myself and felt that I belonged, which was the biggest personal gain. (Para. 5)Every weekend, we haul two 275-gallon water tanks to the nearby town of Yucca and fill them with water, which we then pump into our big water tanks. (Text, Unit 1, Book 2)Frank M. Elliott, 23, who had left Georgetown University to join the Army in 1943, wrote from England. (Text, Unit 2, Book 2)Now combine each of the following pairs of sentences, using a non-restrictive attributive clause.1 The credit card is in my wallet. You can find it in the kitchen cabinet drawer.2 Personal computers have come quite a long way. They were actually invented in 1964.3 My dearest friend ignored my advice. This totally surprised me.4 I went to London with Emily White. She lives next door.5 I lent some money to Jack. His house was destroyed in the earthquake.6 In the past six years I lived in six different houses. Actually this didn’t bother me much.

我们来逐题分析，将每对句子用非限制性定语从句（non-restrictive attributive clause）合并。非限制性定语从句用逗号与主句隔开，提供附加但非必要的信息，不能用 that 引导，常用 who, whom, whose, which, where, when 等引导。

1.

原句：

• The credit card is in my wallet.
• You can find it in the kitchen cabinet drawer.

分析：
“you can find it in the kitchen cabinet drawer” 是对“my wallet”的补充说明，说明钱包的位置。我们可以将第二个句子变成修饰“my wallet”的非限制性定语从句。

合并：
The credit card is in my wallet, which you can find in the kitchen cabinet drawer.

✅ 解释：“which” 指代前面的“my wallet”，用逗号隔开，提供额外信息，不是限定哪个钱包，而是说明这个钱包在哪里。

2.

原句：

• Personal computers have come quite a long way.
• They were actually invented in 1964.

分析：
第二句是对“personal computers”的背景补充，说明它们的发明时间，是非必要信息。

合并：
Personal computers, which were actually invented in 1964, have come quite a long way.

✅ 解释：用“which”引导非限制性定语从句，插入在主语和谓语之间，用逗号隔开，提供附加历史信息。

3.

原句：

• My dearest friend ignored my advice.
• This totally surprised me.

分析：
第二句是对前面整个句子的反应，即“这件事让我很惊讶”。我们可以用“which”指代前面整个主句内容。

合并：
My dearest friend ignored my advice, which totally surprised me.

✅ 解释：“which” 指代前面整件事（朋友无视我的建议），作为非限制性定语从句，说明这个行为让我惊讶。

4.

原句：

• I went to London with Emily White.
• She lives next door.

分析：
第二句是对 Emily White 的补充说明，说明她住在哪里。可用“who”引导非限制性定语从句修饰 Emily White。

合并：
I went to London with Emily White, who lives next door.

✅ 解释：“who” 指代 Emily White，提供额外信息，说明她的住址，但不是限定哪一个 Emily White（假设名字已明确）。

5.

原句：

• I lent some money to Jack.
• His house was destroyed in the earthquake.

分析：
第二句是对 Jack 的补充说明，解释他为什么可能需要钱。可用“whose”引导从句，表示“Jack 的房子”。

合并：
I lent some money to Jack, whose house was destroyed in the earthquake.

✅ 解释：“whose” 是关系代词，表示所属关系，指“Jack’s house”，用逗号隔开，提供背景信息。

6.

原句：

• In the past six years I lived in six different houses.
• Actually this didn’t bother me much.

分析：
第二句是对前面整件事的评价，“这并不怎么困扰我”。“this” 指前面搬家六次的经历。可用“which”指代整个主句。

合并：
In the past six years I lived in six different houses, which didn’t bother me much.

✅ 解释：“which” 指代前面“六年搬六次家”这件事，作为非限制性定语从句，说明作者对此的态度。
