She threw a sharp, sideways glance at Dumbledore here, as though hoping he was going to tell her something, but he didn’t, so she went on.

说到这里，她机敏地朝邓布利多斜瞟了一眼，似乎希望他能告诉她些什么，但邓布利多没有吱声，于是她接着说……

throw a glance at (someone or something)

1. To glance at someone or something very quickly. 非常快地看一眼（瞥、瞟）

That woman at the bar keeps throwing glances at you. You should go talk to her!

酒吧里那位女士一直在看你。你应该过去和她谈谈！

Make sure you throw a glance at the pressure gauge every now and then to make sure it doesn't reach dangerous levels. 你需要时不时瞥一眼压力表（the pressure gauge），以确保其处于安全运作状态。

2. To examine or look over someone or something very quickly or cursorily.非常快地或非常匆忙地检查

Would you mind throwing a glance at my report? I don't want there to be any glaring mistakes before I submit it. 你可以看一下我的报告吗？我想在提交之前确保报告没有任何明显错误（glaring mistakes）。

The doctor just threw a glance at me and said I looked fine. He didn't even take my blood pressure, for Pete's sake! 那位医生只是草草瞥了我一眼，说我看起来很好。天啊（for Pete's sake是 for God's sake更加委婉的表达法），他甚至没有让我量血压！

for goodness', God's, Pete's, heaven's, etc. sake

used to emphasize requests or orders when you are angry or have lost patience

做做好事吧，看在上帝份上，看在老天份上

For goodness' sake don't let her know I told you!

行行好，千万别让她知道是我告诉你的！

Professor McGonagall shot a sharp look at Dumbledore and said, “The owls are nothing next to the rumors that are flying around. You know what everyone’s saying? About why he’s disappeared? About what finally stopped him?”

麦格教授狠狠地瞪了邓布利多一眼，说：“猫头鹰和沸沸扬扬的谣言毫不相干。您知道大伙都在说什么吗？说他为什么失踪？说最终是什么制止了他？”

shoot a look/glance at sb.（shoot sb. a look/glance）

to look at someone quickly, especially so that other people do not see, to show them how you feel 快速看眼某人，尤用于在其他人没有察觉的情况下，向某人展示你的感受（偏向瞥，因为原文中加上sharp，因此处理成带有感情色彩的“瞪”更加游刃有余）

shoot somebody a quick/sharp/warning/furious/anxious/... look/glance

It seemed that Professor McGonagall had reached the point she was most anxious to discuss, the real reason she had been waiting on a cold, hard wall all day, for neither as a cat nor as a woman had she fixed Dumbledore with such a piercing stare as she did now.

这一来，麦格教授似乎点到了她急于想讨论的问题核心，这也正是她在冰冷的砖墙上守候了一整天的原因。不管她是一只猫，或是一个女人，她从来都不曾用现在这样锐利的眼光看邓布利多。

fix sb. with a stare

To look at one intensely 深深注视某人（注视）

He fixed me with a stare, and I found myself mesmerized by what he was saying.

他盯着我看，我发现自己被他说的话迷住了（be mesmerized by）。

Professor McGonagall opened her mouth, changed her mind, swallowed, and then said, “Yes — yes, you’re right, of course. But how is the boy getting here, Dumbledore?” She eyed his cloak suddenly as though she thought he might be hiding Harry underneath it.

麦格教授张开嘴，改变了看法。她咽了口唾沫，接着说：“是啊……是啊，当然您是对的。可怎么把孩子弄到这里来呢，邓布利多？”她突然朝他的斗篷看了一眼，好像他会把哈利藏在斗篷里。

eye sb.

verb [ T ] present participle eyeing or eying

to look at someone or something with interest（饶有兴趣地）看，注视（注视、看、观察）

I could see her eyeing my lunch. 我看到她饶有兴趣地看着我的午饭。

to look closely at someone or something 仔细观察某人或某物

She eyed the other passengers. 她注视着其他乘客。

还记得“光天化日”之下怎么说嘛？哈哈哈哈，忘记的话记得复习一下昨天的知识点哦~
