说出答案并说明理由！
1.He made a great invention again,_______of great help to our daily life.
a.which i think b.l think which is
c.i think itd.which i think is
2.was it on october 1,1949______the people Republic of China was founded?
a.in which
b.on that c.that
d.when
第一个选d,其实是i think which is of grear help to our daily life ,which在这是状语提前，第二个选c,是强调句，原来的语序应该是it was on october1,1949that the people Republic of China wasfounded.that前面不需要介词了，判断一个句子是不是强调句很简单就是看that 后的句子成分是否齐全也就是它是不是一个句子，在这that后的句子意思是中华人民共和国成立了，显然成分齐全，所以是强调句。强调句的句型是it be(am,is was等)that。所以当然选c...
