VOA慢速英语:New Vaccine Joins Campaign to End Polio
be used for被用来做……
例句:The texture of this cloth is too rough to be used for children's clothing.
这中布料质地粗糙,不适合制作儿童服装。
同样的用法:be used to to sth被用来做某事
例句:The money is to be used to create web-based teaching tools in computer architecture.
那些钱将被用于以计算机架构开发基于Web的教学工具。
要注意be used to do 和be used to doing的区别:
be used to doing习惯做某事,后面跟的是动名词形式。
例句:I am used to reading before sleeping.
我习惯在睡前读书。
相应的一个变形是:get used to toing sth,be强调一种状态,get强调一个动作和过程。
2.Carol Pandak is with the PolioPlus program of the service organization Rotary International.
这个用法在VOA慢速英语中体现的最多:某个人属于某个机构不用In,也不用of,而是用with后面跟所属的机构。
3.As a result, few new cases of type two have been reported since nineteen ninety-nine.
few含有否定的意思,little也是如此。
不带a的little和few 含有否定意义,表示数量很少或几乎没有,强调“少”;带有a 的little和few含有肯定意义,表示数量虽然少但毕竟还有,强调“有”。比较:
Few people like such things. 没什么人喜欢那样的东西。
A few people like such things. 有少数人喜欢那样的东西。
He knows little English. 他几乎不懂英语。
He knows a little English. 他懂一点点英语。
注意,当few前不带 a,但带有the, some these, those等修饰语时,也表示肯定意义。如:
Some few have already left. 有几个已经离开了。
The last few winters have been very cold.过去几个冬天都很冷。
The first few chapters are about his early days.前几章谈他的少年时期。
4.This has led to greater use of monovalent vaccines to protect against either type one or type three polio.
either...or...意为"或者……或者……;不是……就是……"之意。表示两者之一,连接句子中两个并列的成分。连接主语时要注意就近原则。谓语和离谓语动词最近的主语保持人称和数的一致。
例句:Either an author or a man interested in literature is named a literary man.
一个作者或一个对文学感兴趣的人被称作文人。
