答案解析
Step 1
.

.
1．用名词或代词作同位语。2．用形容词作同位语。5．用-ing形式作同位语。6．用
不定式作同位语。
*1由两个或两个以上同一层次的语言单位组成的结构,其中前项与后项所指相同 ,句法
功能也相同,后项是前项的<同位语>。
our new teacher是<主语>Mr. Smith的<同位语>,指同一人。
a friend of my brother's是<宾语>Tom的<同位语>,指同一人。
*2如<同位语>与其同位成 分关系紧密时不用逗点隔开;如<同位语>对其同位成分只作补
充解释时可用逗点隔开。
himself和John都是单一的字作<同位语>,与其同位成分之间不用逗点隔开。
*3<同位语>除表示其同位成分的全部意义外,还可以表示部分意义。
如<同位语>与其同 位成分关系紧密时不用逗点隔开;如<同位语>对其同位成分只作补
充解释时可用逗点隔开。
*4<同位语>除表示其同位成分的全部意义外,还可以表示部分意义。（11，12）
Step2:同位语的句子1，That 2, whether.3,whether,4, that, 5, where, 6, how, 7, that定语
的句子
句的that she should stay in the room这个从句说明了建议的内容，同时， that只起连
词作用，在从句中既不是主语，也不是宾语，但不能省略，所以它是同位语从句。
寻规找矩：
我们可用连词that, whether以及连接代词who, which, what和连接副词how, when,
where, why等来引导从句作同位语，称为同位语从句。在同位语从句中that 虽不作句子
.

.
成分，且无意义，但不可省略。同位语从句常对一些抽象名词做进一步的解释和说明。这
些 名词常见的有：idea, fact, news, hope, belief, suggestion, proposal, word, thought, doubt,
truth, possibility, promise, order 等。
step 3.巩固练习
1：that 2．wherever 3．whether r5 when 6 that 7．whichever 8 that 9. When
10. whether 11. whatever 12. Wherever 13. where 14. why
Step4 translation
1.

2. We'll discuss the problem whether the sports meeting will be held on time．
3. The general gave the order that the soldiers should cross the river at once．

.
11. They didn't answer the question where they were born.
12. We have no information whether he is alive.
补充：一、定语从句相当于一个形容词, 它对先行词起 修饰、描述和限制的作用。同位
语从句相当于名词，属于名词性从句，它是对前面名词内容的具体表述， 它们之间的关系
是同位关系。
二、同位语从句常跟在 news, fact, promise, idea, word, message, hope, truth, answer,
proposal, suggestion, order, information 等少数名词之后，而一般名词之后都可跟定语从
句。
三、that 在定语从句中充当某一成分, 是关系代词; that 在同位语从句中不作任何成
分，仅把主句与从句连接在一起，是从属连词。
四、when, where, why, how, who, whom, which 如果引导定语从句, 它们分别指前面先
行词所表示的时间、地点、原因、方式、人和物，否则引导的就是同位语从句。
五、whether, what 可引导同位语从句，但通常不可引导定语从句。
