【用音乐过生活】
《X & Y》——Coldplay
———————————————-
Trying hard to speak and
Fighting with my weak hand
Driven to distraction
It's all part of the plan
When something is broken
And you try to fix it
Trying to repair it
Any way you can
I dive in at the deep end
You become my best friend
I want to love you but I don't know if I can
I know something is broken
And I'm trying to fix it
Trying to repair it
Any way I can
Ooh
You and me are floating on a tidal wave
Together
You and me are drifting into outer space
And singing
Ooh, ooh
You and me are floating on a tidal wave
Together
You and me are drifting into outer space
You and me are floating on a tidal wave
Together
You and me are drifting into outer space
And singing
Ooh, ooh, ooh, ooh

#小班课# 【1/22 每日一题】

-When shall I pay a call on you, in the morning or afternoon?
-_______. I'll be in all day.

A. Any
B. None
C. Neither
D. Either

答案来啦：D
【句子翻译】：
-我应该什么时候来呢，早上还是下午？
-早上或下午都可以，我一天都在家。

【题干拓展】：
这个句子里的两个日常的单词：call和in，表达的意思都有一点特殊。
call在这里表示“拜访”，pay a call on sb即表示”拜访某人“
比如：
A market researcher paid a call on my uncle last night.
一位市场调查员昨天来找过我叔叔。

in在这里表示：”at home or at a place of work “，即在家/工作单位
比如：Nobody was in when we called him. 我们打电话时家里没人。

同学们可能好奇，为啥不选A，这个题目中，给了一个选择范围，咱们要二选一的话，D选项最符合哦～

如果没有选择范围，则A！
