Question

1. --- Where is Amy?
--- She____ (go) to Guilin. She’ll be back next week
2. He____ (visit) many foreign countries and____(learn) several foreign languages
since 1991
3. ---____ did you come here this morning?
---____ I have finished my homework
A. When; When B. When; What time
C. What time; When D. What time; What time

Answer 1

1.第一个句子应用现在完成时，She_has gone___ (go) to Guilin.
has gone to去了某地还没有回来

2. has visited. learned
自从1991年以来，他已经参观过许多外国国家并且学会了几门外语。
since 1991 用现在完成时态，第二个空避免重复，省掉has.

3. A.第一个空指 when什么时候，第二个空，当什么时候
When要比What time范围更大些,what time 是问某具体的时间点

解答如下:
1,What time does your class begin at?
Our class begins at 9;00.
2,How often do you go to the park?
I go to the park every day.
3,When do you do your homework?
I do my home work at night.

Answer 2

你好：
1 goes 一般现在时态， she 是第三人称单数， 助动词用三单形式

2 has visited ; has learned since 1991 用现在完成时态

3 C what time 可以用于问句，但不能用于答句； when 既可以用于问句也可以用于答句

翻译；你今早上什么时候来这里的？ 当我完成我的家庭作业后（就来了）

希望对您有帮助！不清楚的请追问！！
