2. lie vi. 说谎；躺；位于
n. 谎话；谎言
(课文原句) He could not have Yong Hui getting away with telling people lies!
翻译：他可不能让雍慧哄骗人们却不受惩罚！
【归纳】
tell a lie/lies 说谎
lie to sb. 向某人说谎
lie in 在于；存在于
1) lie用作规则动词(lie，lied，lied) 时意为“说谎”。如：
She?lied?to?us?about?her?job.?
【注意】
表示这一意思时，lie可用作名词。我们一般说tell?a?lie或tell?lies，而不说say/talk/speak?a?lie(或lies)。
辨析
lie，lie，lay
2) lie用作不规则动词(lie，lay，lain)时，表示 “躺”，“(东西)平放”，“位于”等意。 e.g. He’s?still?lying?in?bed.?他还躺在床上。
3) 动词lay也是不规则动词(lay，laid，laid)，是及物动词，后面必须接宾语。表示“放置” “产卵”等多种意思。如：
He?laid?his?hand?on?my?shoulder.?
他把手放在我的肩上。
The?hen?is?laying?an?egg.?母鸡在下蛋。
【注意】
lay，put，place和set都可用来表示“放置”某一物体。lay表示把某物横着或摊开着平放。put较普通，指较随意的放，不强调所放物体的姿态，可代替其它几个动词。place是比较正式的用语，指有意识地把某物放在较为确定的位置上或安排某物的顺序，有时含有较庄重的语气。set特指把某物垂直着放。
【提示】注意以下词形变化。
原形 过去式 过去分词 现在分词 词义 词性
lie lied lied lying 说谎 不及物
lie lay lain lying 躺；位于 不及物
lay laid laid laying 放置；
下蛋 及物
三者所表示的位置关系不同。试比较：
New York lies in the east of America.
纽约位于美国东部。(包含关系)
Japan lies to the east of China.
日本位于中国以东。(不包含关系)
America lies on the east of the Pacific.
美国位于太平洋东岸。(相邻关系)
lie in, lie to和lie on

5. glare n. “刺眼的强光，令人不快的光，
怒视的目光，愤怒的表情”。
v. “发耀眼的强光，怒视”。
作“怒视”讲时，常用于glare at结构。
(课文原句) She did not look happy but glared at him.
翻译：雍慧瞪着他，看上去不高兴。
【拓展】
glaring? adj. 耀眼的，显著的，怒视的
glare at “怒目而视，恶狠狠地盯着”，带有生气的感彩。glare at sb. 意思相当于stare at sb. angrily。如：
Don’t glare at your father like that!?
stare at“凝视，盯着看”，仅仅表示动作，不带有感彩。如：
Rose’s father?lifted?his?head?and?stared?at?
her.

glance at “匆匆一瞥，迅速地看一眼”，强调这个动作速度很快。如：
Glancing at her watch, Jane saw that she was late.
