1 We know that a housewife does not need( )for food every da

问题补充：不好意思 刚才没有写完整 第二个单选 给出的答案是C
给了也白给,还是错的,有always,一般都是进行时,有感情色彩.
具体已解释过了.
1 We know that a housewife does not need( )for food every day.
B to go shopping D to go to shopping
答案是D
呃,答案错了.go shopping 是词组.
2 Nobody likes him because he ( )others.
A is always criticizing B always criticizes
C does always criticize
A is always criticizing 进行时有时表示感情色彩.
没人喜欢他,因为他总是批评别人.很显然,有讨厌的意思.用进行时.
3 I ( )my breakfast when the morning post came.
A had B had been having C have been having D was having
D was having
当早晨的邮件（/报纸信之类）到的时候,我正吃早餐.
可见是过去进行时,因为有具体时间,完成时一定不对.
而.WHEN.句型,从句一般时,主句进行时,几乎百分百.
4 James has just arrived,but I didnt know he ( )until yesterday.
答案 had been coming
吉姆刚到,可我刚才却不知道,他昨天就在路上了.
可见,是过去完成进行.
以过去为基点,正在进行的动作,
在说话人所说的那个“时间”完成了,对当时还有影响,是过去完成进行时,
不懂~
