A.a,a B.a,the C.the,the D.the,a
(本题选A)
2.Housing prices __sharply in the past six months,and I doubt whether I can afford a buy if things go on like this.
A.are rising B.have risen(本题选B,我选的A,为什么不能理解为持续的增长?)

A.unless B.even if C.because D.as long as

第一个题目选A的原因 ：a profound effect on 是一个固定搭配,对...有重要作用,重大影响的意思；the most important invention （most 是形容词的最高级,和the 搭配使用,表示最重要的发明）和a most important invention （most此处是形容词,意思和用法相当于very,和a搭配使用,表示一项重要发明）两种表示语法上都正确,到底用a 还是the就要根据句意来判断了.原句前半句话的意思：网络对人们的日常生活有重大影响,后半句中的but 表示了转折,only强调了不过如此,仅仅而已,根据句意选择a most important invention
第二个题目根据句意看出,房价上涨对我现在能否购买造成了影响,A 和B 选项语法上都正确,但两者相比较而言,B的完成时态更强调过去对现在的影响,B是最佳选项.
第三个题目,as有因为的意思, 但是as long as 则是“只要”的意思.

第一题，第一个空是固定搭配啦，第二空靠理解当然英特网只是历史中的一个重要发明。而不是最重要的！
第二题，关键在题目已经给出了时间状语！在过去的六个月里，时态一定要一致啊！！不过你理解得不错，因为房价一直在涨，但务必注意时态哈！
第三题，C选项是最佳的，表示很直接最重要的因果关系啊！D不是只有只要和与什么一样长的意思么？...

as long as 的意思是只要，不是得的意思，去查一查词典吧
比如 I will love you as long as I breathe. 直译，我会爱你只要我还会呼吸，意译，我会永远爱你。

1.have an effect on “对...有影响”
have a profound effect on “对...有深远影响”
第二空the most 表最高级；a most 相当于very是“非常”,此处不表最高级，所以选 a most
2. 此题关键在于 in the past six months表示从过去到现在的时间，所以选现在完成时，后半句I doubt ...

2. 此题关键在于 in the past six months表示从过去到现在的时间，所以选现在完成时，后半句I doubt whether I can afford a buy if things go on like this表这件事不一定持续下去，所以不能选进行时
3. unless 和 as long as 都表条件，但he had his foot injured in a match 表前句不能实现的原因，故单选because
