n.(名詞)

beam通常指“光束”，即從發(fā)光體向某方向射出的有一定寬度的光線，尤指定向的無線電波。

v.(動(dòng)詞)

beam的基本意思是日、月、燈塔等發(fā)出光束,引申可表示“定向發(fā)出(無線信號(hào)等)”“播送”,用于比喻可表示“面露喜色”。

beam一般作“面露喜色”解時(shí)是不及物動(dòng)詞,可接介詞at或on〔upon〕,表示“對(duì)…微笑”。

beam作“播送”解時(shí)是及物動(dòng)詞,常用于被動(dòng)結(jié)構(gòu),接介詞to,表示“向…播送…”。

n.(名詞)

beam, ray

這兩個(gè)詞的共同意思是“光線”。其區(qū)別是：

1.beam指由日、月、燈或激光器等發(fā)出的有一定寬度的光線，即光束、光柱; ray指由發(fā)光體發(fā)出的成為線形的光。ray在科技術(shù)語中又指射線。用于比喻則可指智慧等的閃光。

2.在通俗用法中beam是比ray更強(qiáng)的光線; ray是構(gòu)成beam的許多光線中的一條。例如:

There I saw the glorious beams of the rising sun.在那里我看見了初升太陽的光芒。

The searchlight sent its beam into the night sky.探照燈的燈光射入夜空。

v.(動(dòng)詞)

beam, chuckle, giggle, grin, laugh, smile, sneer

這組詞的共同意思是“笑”。其區(qū)別是：

1.laugh指一般地“笑”或“出聲大笑”;smile指“不出聲微笑”;beam指“面帶笑容”;chuckle指“吃吃笑”或“暗自發(fā)笑”;giggle指“咯咯地笑”“傻笑”;grin指“咧嘴笑”“露齒笑”;sneer指“冷笑”“嘲笑”。例如:

Father smiled his approval.父親以微笑表示贊許。

The boys and girls are jumping and laughing on the playground.孩子們在操場上又跳又笑。

The girl giggled.那個(gè)女孩咯咯地笑。

She grinned with delight.她高興地咧開嘴笑。

I could hear him chuckling to himself as he read his book.他看書時(shí),我能聽見他在輕聲發(fā)笑。

Don't sneer at their religion.不要嘲笑他們的宗教。

2.smile表示愉快、興奮、同情、輕蔑、諷刺、無奈等各種心情;beam暗示對(duì)他人友好、善良或內(nèi)心滿意;chuckle有得意或領(lǐng)略到其中趣味的含義;giggle是不好意思地笑或由某一趣味而連續(xù)“癡笑”;grin多因高興、滿足或輕蔑而笑;而sneer則以表情、聲調(diào)或語言表示對(duì)某人〔事〕的輕蔑與嘲弄。

3.smile, laugh是一般用語;beam是正式用語;chuckle多用于書面語中;giggle多用于女人或孩子。
