GWD1的另两道题！

Q32:

To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.

1. have to know a great deal more than now about the social and economic
2. have to know a great deal more than they do now about the social and economical
3. would have to know a great deal more than they do now about the social and economical
4. would have to know a great deal more than they do now about the social and economic

5. would have to know a great deal more than now about the social and economical

蓝色是我选的，红色是正确答案。

为什么than后面直接跟now，啥都不需要了？OG11上economical是指节约的，这里又指经济的了？

1. took 700,000 artisans more than 36 years to complete them
2. took 700,000 artisans more than 36 years to complete it

3. took 700,000 artisans more than 36 years to complete

4. 700,000 artisans took more than 36 years to complete
5. to complete them too 700,000 artisans more than 36 years

 The army of terra-cotta warriors is 2000 years old and took……to complete it.

最后需要加it吗？看起来很奇怪。

你确定没对错答案？ 第二题选C，

第一题 D

NO NO NO,蓝色是我的答案

正确答案第一题E，第二题B，就是红色的。

第二题确定是 C ， i give you a book to read （it）    这里IT不用加，当to do 做宾补时。

第一题还是第一次看， 

would 一定要加， 因为是要和NOW 比，  they do 补不补无所谓，  后面的economic 才是经济的

the correct answer of the first is D, where are your answers from?

economical, =saving
