OG几个有疑惑的语法点！

1.      According to public healthofficials, in 1998 Massachusetts became the first state in which more babieswere born to women over the age of thirty than under it.

A.     Than

B.     Than born

C.     Than they were

D.     Than there had been

E.      Than had been born

问：PREP中的，正确A，我错选了B，想不通……

2.      Due to可以放句首吗？

3.      The Iroquois were primarily planters, but

supplementing their cultivation of maize, squash,

and beans with fishing and hunting.

(A) but supplementing

(B) and had supplemented

(C) and even though they supplemented

(D) although they supplemented

(E) butwith supplementing

OG的解释说选A不对是因为原句要表达的是一种contrast，而非动词的extension，所以不该用分词作伴随状语——这一点我明白了。但我想问的是：but可以加-ing做伴随状语的吗？but和although不是应该加完整的句子的吗？？

4.      As a baby emerges from the darkness of the womb

with a rudimentary sense of vision, it would be rated

about 20/500, or legally blind if it were an adult with

such vision.

(A) As a baby emerges from the darkness of the

womb with a rudimentary sense of vision, it

would be rated about 20/500, or legally blind if

it were an adult with such vision.

(B) A baby emerges from the darkness of the womb

with a rudimentary sense of vision that would be

rated about 20/500, or legally blind as an adult.

(C) As a baby emerges from the darkness of the

womb, its rudimentary sense of vision would be

rated about 20/500; qualifying it to be legally

blind if an adult.

(D) A baby emerges from the darkness of the womb

with a rudimentary sense of vision that would be

rated about 20/500; an adult with such vision

would be deemed legally blind.

(E) As a baby emerges from the darkness of the

womb, its rudimentary sense of vision, which

would deemed legally blind for an adult, would

be ratedabout 20/500.

问：选E为什么不对？OG解释说：Subordinate clause beginning with which is

awkward andambiguous.但还是不大明白啊……

5.      The use of lie detectors is based on the assumption

that lying produces emotional reactions in an individual

that, in turn, create unconscious physiological

responses.

(A) that, in turn, create unconscious physiological

responses

(B) that creates unconscious physiological

responses in turn

(C) creating, in turn, unconscious physiological

responses

(D) to create, in turn, physiological responses that

are unconscious

(E) who creates unconscious physiological

responsesin turn

问：这题我选了B，解释说creates的单复数与reactions不一致，我就纳闷了：定语从句that不应该紧跟先行词，也就是说that不是应该修饰的是an individual吗，怎么这里成修饰reactions了？？

我试着回答下
1，这里前后比较的是介词短语'，而不是主语，所以不需要补出谓语
2， due to means caused by,不能位于句首
3，but既可以做连词也可以做介词，做连词当然连接完整句子没错。做介词可接名次，介词短语，代词风，我觉得接ving有问题，一般伴随状语都是comma+ving的形式，之间没有其他词语
4.which就近修饰vision，vision cannot beblind，a person can be blind.
5.句子的逻辑意思是，测谎仪的使用是基于这样的假设，即一个人说谎时会产生情绪反应，而这种反应会反过来产生无意识的生理反应。所以creat要和reactions数上保持一致。

2， due to means caused by ...

我也来补充一下，

3) but supplementing 可以认为but是副词，但原句的意思要对比而不是用supplementing来伴随。

5) that不可以指代individual ，最近可以指代的词就是reactions
