1. 请先观察以下短语，这几组短语至少在表示某一意思时它们是反义词：
(1) up 与 down 是一对反义词，前者表示“向上”，后者表示“向下”。如：
He continued to jump up and down like a boy at a football match. 他不停地上蹿下跳，活像个足球赛中的男孩。
Aircraft can avoid each other by going up and down, as well as by altering course to left or right. 飞机可以通过上下升降和左右移动改变航线来避免相撞。
(2) upstairs 与 downstairs是一对反义词，前者表示“楼上”，后者表示“楼下”。如：

单词：slow的近义词、反义词、形近词辨析
slow/slowly
A feather falls slower than a stone.羽毛比石头落得慢。
He observed that feathers fell to the ground slowly.他观察到羽毛落地很慢。
<辨析>两者都可以用作副词，表示“慢慢地”的意思。slow 常用在动词 go,drive,speak,read 等后面或副词 how 后面。如：How slow he walks!他走得多慢啊！My watch goes slow.我的表经常慢。slowly 可置于行为动词的前后或句首。如：Mr Baker's face slowly turned red.贝克先生的脸慢慢地变红了。slow 的比较级和最高级是 slower,slowest；而 slowly 的比较级和最高级是 more slowly,most slowly。slow 还可作形容词，意为“慢的”、“迟钝的”。如：He was old and slow.他年纪大，行动迟缓。
