复合动词是以一个动词为主体,在它的前面加上一个词(通常加名词、形容词和副词),用连字符或不用连字符构成的动词。
例:Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free…(2020年高考浙江1月卷阅读理解B篇)
road test为复合动词,意为“在道路上测试”,也可引申为“(各种)试用”,如:
The company may offer free samples of its skincare products so you can road test them. 这家公司可能会送出化妆品样品,这样你就可以试用一下。(剑桥词典)
live stream(直播)和password protect(设置密码保护)也是两个常用的复合动词,如:
- My brother live streams himself playing games. 我弟弟直播自己玩游戏。
- You’d better password protect your files in the computer which contain important data. 你最好在电脑上设置密码保护那些含有重要数据的文件。
