二、right的用法
1、right的基本意思是“正当的,适当的,合法的”,指某人做某事符合法律的规定,具有合法性,也可指某人做某事或选择某物是“对的,正确的”。right也可指“右边的,右方的”,与其相对应的是left。right还可指“切合实际的,最适宜的,最恰当的”“良好的,正常的”“真实的,完全的”等。
2、right在句中可用作定语,也可用作表语。用作表语时,其后可接介词短语、动词不定式或由that引导的从句。
3、right用作副词意思是“直接地”,指某事的发生没有经过其他的环节直接达到最后的效果,也可指“彻底地,完全地”。right还可指“向右,往右”,指呈现出向右边的运动趋势。right还可指“正确地,恰当地,令人满意地”或“立即,马上”等。
4、right通常可以和动词、介词短语或副词连用。与动词连用时, right须放在动词之后; 与其他副词连用时,须放在其他副词之前。
5、right在句中可起加强语气的作用,以便精确地表达时间关系或空间关系,如right after, right in the middle of等。
三、left短语搭配
deliver a left 用左拳出击
keep to the left 靠左边走
make a left 向左拐
take a left 向左拐
throw a left 击一左拳
turn left here 由此往左
四、left的用法
1、left的基本意思是“左”,可指“左边,左侧,左部”,是不可数名词。表示“左翼,社会主义拥护者”时,常与the连用,且大写,是集体名词;在强调整体时,谓语动词用单数形式;强调成员个体时,谓语动词用复数形式。
2、left的基本意思是“左侧的,左边的,左面的,左方的”,在句中常作定语。引申则表示“左翼的,左倾的”,在句中常作表语。
3、left只有表示“左翼的,左倾的”时,才有比较级和最高级(lefter, leftest或more left, most left)。
4、在简单的表示“左”或“右”的方位时，只可以用on the left/right，不可用at the left/right；
5、on one's left/right有时可用on the left/right，at one's left/right，或是to one's left/right等表达方式来替换，不过在表示较长的距离时，习惯上用to。
