多谢rattledrum的解答，关于主语从句没什么好疑问的。关于同位语从句有点不明白的地方，同位语不是用来解释修饰一个名词的嘛，一般要用另外一个名词放在逗号后吧，而b的namely是个副词阿，我当时剔除b是因为觉得它逗号后面是个that从句，而前面是主句不符合逗号只能连接两个句子的规则。所以谁能解答一下这个疑惑

rattledrum

namely可以接that

that从句可以充当同位语，不是同位语只能是n.

建议LZ去读一下《白勇》

这个书我看过了,在讲从句那里?可能我看的不是很仔细啊.另外~~

Like the grassy fields and old pastures that the upland sandpiper needs for feeding and nesting when it returns in May after wintering in the Argentine Pampas, the sandpipers vanishing in the northeastern United States is a result of residential and industrial development and of changes in farming practices.

 

A.    the sandpipers vanishing in the northeastern United States is a result of residential and industrial development and of changes in

B.    the bird itself is vanishing in the northeastern United States as a result of residential and industrial development and of changes in

这里A的话是不是主语是 the sandpipers vanishing~~请问这是一个什么结构~~中心词是哪个？多谢~~

Unlike the original National Museum of Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to “touch” each exhibit, which thereby activates the animated functions of the piece.

 

A.    exhibit, which thereby activates

B.    exhibit, in turn an activation of

C.    exhibit, and it will activate

D.    exhibit and thereby activate

E.     exhibit which, as a result, activates

这个答案是d，可是我不明白，这里的activate是谁发出的，主语不是project嘛这不是一个单数嘛，另外which，it都不能指代一个事情，所以我觉得尽管b的结构不常见但是只能用它了~~上面是我解题时的思路，大家诊断一下看问题出在哪里了~

 

iser

activate的主语是visitors，（to）touch and activate并列。

可是从逻辑意思上讲activate作用的应该是“允许游客触摸”这项举措吧~~而不是游客发出的吧
