Ｐ３９页Ｅ３－３：

(Japan received huge sums of capital from the US after the Second World War ,using it to help build) a modern industrial system.

答案是：Japan used the huge sums of capital it received from the US after the Second World War to help build这里it指代什么，我觉得它是多余的

还有一道题目:

Out of America's fascination with all (things antique have grown a market of bygone styles of furniture and fixtures that are bringing

)back the chaise lounge,the overstuffed aofa,and the claw-footed bathtub.

答案是B:things antique has grown a market for bygone styles of furnt

ure and fixtures that is bringing

书上解释说该句真正的主语是a market,谓语为has grown,看的不太懂,请大侠们指点一下,并给出翻译,多谢!

我还有一道题:E7-10(Based on the growth rates of large modern reptiles such as )the G and examination of fossils of juvenile dino

saurs, scientists estimate that the larger dinosaurs probably lived to be between 100 and 200 years old.

答案是B On the basis of growth rates of large modern reptiles such as 是不是因为based表示被动啊?逻辑主语不是对的吗?
