newspapers and magazines can keep us ------ about what is happening at home and abroad A informing
newspapers and magazines can keep us ------ about what is happening at home and abroad A informing
B informed 选择哪个?
-------in the Koor is for years ,i decided to learn their language
A having interested B having been interested
Della had only one dollar ---------jim,her huaband ,present 为什么是with which to buy
Do the Tom live next door to you
A used to B used to do
1, informed.现在分词表示主动地,进行的.过去分词表示被动的,完成的. inform通知.我们是被通知的.所以用过去分词.
2,选B.这个其实很简单,词组be interested in才是对.感兴趣的意思.所以A选项没有be动词跟定不对,根据句意,已经感兴趣了很长时间了比如： i have been interested in music for years. 所以,现在分词做状语表伴随,把have变为having,完事了.
3,把这个含有定语从句的句子拆分成两个句子：
della had only one dollar. she would buy her husband present WITH one dollar.
在原句中which这个关系代词代的就是one dollar,所以one dollar前面的with当然不能没有了.
4 used to do表示曾经,过去.be used to doing 表示习惯于.这个应该用used to.他们过去住在我隔壁而不是他们习惯祝我隔壁
