延续两个礼拜前分享的“不藏私自修实用资源3”里提到的词语搭配概念，
今天想在跟同学分享一下英英字典里大家常忽略的实用技巧，也就是单字常
连着用的“介系词”。相信大家如果看过我之前的一些文章会开始注意到学
习新单字时，“例句”的重要性。但除此之外，要彻彻底底把这个字学起
来，同学也要特别注意介系词的用法。
举一个例子：alternative (n.) 替代方案; 其他选择, 这个字如果查
learnersdictionary, 除了先给英英解释以外，下一行会告诉你
— often + to, 如这个例句：Doctors have been looking for alternatives
to the usual treatment, but it seems there are few options.
有些字甚至会告诉你后面一定接的词性，例如imperial (adj.) : of or
relating to an empire or an emperor帝国的; 皇帝的, 字典会在下一行
告诉你always used before a noun, 像是the Roman imperial age,
imperial villas, 所以这个字是不可以单独使用的！
仔细了解介系词用法有两个好处。
1)平常如果记熟，在口说写作中不会用错，而且会自然的使用出来，不用在
当下还要思考。
2)其实无形之中可以让你阅读速度变快，因为你会预期看到alternative有
很大的机会接介系词“to”,从而预期接下来的“xxx的替代方案”这样的概
念。
了解此概念后，大家不妨用以下句子来测试一下这些单字你真的会用吗？以
下的句子全部来自TPO或真题, 都是非常常见的单字，可以顺便把这些字学起来喔！
1. Wind energy is being touted ___ an alternative energy to
satisfy out future global energy needs.
2. Wealth and status would most likely accrue ___ the elites of
the decision-making hierarchies. (*可以顺便再查一下hierarchy这个
字，在这里并不是一般常见的意思喔！)
3. A major shift ___ opinion occurred when it was shown that
poets who had been illiterate (unable to read or write) could in
fact compose long poems.
4. This article was the impetus ___ public support for the
building of a park in New York City.
5. The way he drew even non-human characters was dismissed by
many critics ___ being overly simplistic.
6. The radio transmitter method was time consuming for
researchers but provided a much better snapshot ___ migration than
the leg bands ever allowed.
7. The first steps toward change were taken by Solon in 594 B.C.,
when he broke the aristocracy's stranglehold ___ elected offices
by establishing wealth rather than birth as the basis of office
holding.
8. When we need to tap into energy, the compressed air can be
released and funneled ___ a device that converts it back into
electricity.
请先做完再往下拉看答案喔！
公布答案，建议同学这些字可以再利用英英字典再查一次，利用其他例句
加深印象，比直接看答案效果更好喔！
1. as
2. to
3. in
4. for
5. as
6. of
7. on
8. through
希望今天的分享能让大家更了解单字学习方式，并能更认识字典大家常忽略
的一块，每次学习单字时有意识的记住这些介系词用法，方能在口说写作时
更直接的使用，阅读也会变快，听力更能快速吸收资讯喔！
祝大家狗年行大运，好运汪汪来！
