Zero in on：你为什么不试着用英语学英语？用英语理解英语？
你冷不丁问我：英语短语zero in on“什么意思？”(你问中文还是英文？)，我当然不知道，但也不能望文生义按字面理解呀！
但是，我会去查英英字典，一，“我知道了”！
1) 查英英字典：
Verb Phrases：zero in on
1. to aim something,such as a gun,a rifle,a camera,etc. at the precise center or range of a target.
2. to aim directly at (a target).
3. to direct one's attention to;to focus/ concentrate our attention on something
4. to close in on something
5. to direct all of one's attention to (someone or something)
你可以不认识zero in on，但是，你总会认识里面的to aim something,such as a gun,a rifle,a camera,etc. at the precise center or range of a target, to direct one's attention to; focus/concentrate our attention on something,. to close in on something这些“学过”的英语吧？
2) Put English into English英语口语训练
1.Okay.Got it.I know what zero in on means now.
2.When we say：We zero in on somebody or something, we mean：
We aim something,such as a gun,a rifle,a camera,etc. at the precise center or range of a target.
3. We mean：
We focus/concentrate our attention on something,or somebody
4. We mean：
We close in on something or somebody.
For example,We can say：
We are zeroing in on a solution to this problem.
多强迫自己多体验英语，用“别的学过的”英语理解要学习的英语，肯定比你总是“站在门外”，用一门外语去“学”另外一门外语好的多。
你需要训练出这个能力，而不仅仅止步于“用中文懂得”zero in on“什么意思”。
