slow up和slow down是同义词还是反义词 一、先测测你是否会想当然 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: The bedrooms are upstairs and the dining-room is downstairs. 寝室在楼上,餐厅在楼下。 (3) go up 与 go down 是一对反义词,前者表示“上升”,后者表示“下降”。如: The incomes of skilled workers went up. Meanwhile, unskilled workers saw their earnings go down. 熟练工的收入上升了,而与此同时,不熟练工发现他们的收入下降了。 (4) turn up 与 turn down 是一对反义词,前者表示“开大音量”,后者表示“关小音量”。如: The baby fell asleep, so I asked him to turn the TV down, but a few minutes later he turned it up again. 宝宝睡着了,所以我叫他把电视机音量调小些,但是没过几分钟他又把音量调大了。 ▲请从所给的四个选项中选择一个最佳答案填空: slow up 与 slow down 是一对 ________。 A. 同义词 B. 反义词 C. 无关词 D. 互补词 【测试结果】如果你选择的答案是“反义词”,你就错了,正确答案是填“同义词”。尽管up和down是一对反义词,并且确实也有不少含有up和down的短语也是反义词,但是,slow up和slow down却是一对同义词。 二、相关词和短语的用法说明 slow up和slow down均表示“变缓”“变慢”“减速”等,从使用的广泛性来看,slow down比slow up用得更多、更广泛。两者的具体用法如下: 1. 表示“(使)慢下来”“(使)减速” (1) slow down的用例: I put on the brakes and slowed the car down. 我踩下刹车降低车速。 The train slowed down as it went around the bend. 火车在转弯处减速了。 She slowed down her pace so I could keep up with her. 她放慢脚步好让我跟上她。 The train slowed down to a crawl as it approached the station. 火车进站时慢了下来。 You see drivers speeding up when they should be slowing down. 你可以看到有些司机在应该减速时却加速。 (2) slow up的用例: The bus slowed up as it approached the junction. 公共汽车在驶近交叉路口时放慢了速度。 The roadworks are slowing the traffic up in the mornings. 道路施工使早上的交通迟缓下来。 2. 表示“(使某人)松弛”“(使发展)减缓” (1) slow down的用例: The economy has slowed down. 经济放缓了。 He looks ill, and he should slow down. 他看上去不太舒服,应该放松一下。 (2) slow up的用例: Output has slowed (up) a little. 生产已放慢了一点。 They claim they can slow up the ageing process. 他们声称能够减缓老化的速度。
