【句子】

【解析】

1. where

1)where引導定語從句時是作關系副詞，在從句里代替先行詞充當地點狀語的成分，相當于介詞（in / at / on / ...）+which。

① Stephen Hawking believes that the earth is unlikely to the only planet _where_ life has developed gradually. （2010福建卷，24）

② The girl arranged to have piano lessons at the training centre with her sister _where_ she would stay for an hour. （2010 江西卷，31）

2)在近年來高考英語對于where的考查中，先行詞不僅僅是限于明顯的表示具體地點的名詞，也有表模糊化地點或表抽象化地點的名詞，在這一類先行詞后也可由where引導定語從句，在定語從句中作狀語。這類模糊化的或表抽象的地點名詞有：point, position, situation, condition, state，atmosphere, case, scene, business, stage等。例如：

① I have reached a point in my life _where__ I am supposed to make decisions of my own. （2009 浙江卷，14）

②It’s helpful to put children in a situation _where__ they can see themselves differently. （2009 福建卷，24）?

3)在定語從句中，where還可以作介詞的賓語，即由“介詞+where”引導定語從句。例如：

She stood near the window, _from where__ she could see what happened.

4) where引導地點狀語從句時是作從屬連詞，意為“在……的地方”或“到……的地方”。

Today, we will begin _where__ we stopped yesterday, so that no point will be left out. （2010重慶卷，32）

【注意】
1.指具體地點時，地點狀語從句可置于主句之前或之后；表示抽象條件的含義時，地點狀語從句須放在主句之前。

①Where there is a will, there is a way. 有志者事竟成。
②Wherever there I smoke, there is a fire. 無風不起浪。

2. 另外要特別注意區(qū)分where引導的地點狀語從句與定語從句：

— Mom, what did your doctor say?
— He advised me to live _where__ the air is fresher. （2006 四川卷，23）?

2.joint

He suffers from arthritis in his leg joints.
他的腿有關節(jié)炎。

2)關節(jié)

The pipe was rusted at the joint.

3)聯(lián)合的,共同的

4)合辦的,共有的

We have opened a joint account at the bank.

3.thigh
