倍数及限定词

倍数的表达法：

1）倍数+ as + adj. + as ....

The square is five times as large as st.peter’s in Rome.

2）倍数+ 形容词比较级+ than ...

The square is five times larger than st.peter’s in Rome.

3）倍数+ the + size/length等名词+ of ...

The square is five times the sizes of st.peter’s in Rome.

按其不同的搭配位置，限定词可分为：

1〕中位、前位、后位限定词

按照限定词与限定词之间不同搭配位置，限定词可分为中位限定词（CENTRAL DETERMINER〕、前位限定词（PREDETERMINER〕和后位限定词（POSTDETERMINER〕。

a) 中位限定词包括a(n), the, zero; this, that, these, those; my, your, etc; Merry's, my friend's; some, any, no, every, each, either, neither, enough; what(ever), which(ever), whose等

b) 前位限定词包括all, both, half; double, twice, three times, etc; one-third, two-fifths, etc; what, such, (a / an)等

c) 后位限定词包括one, two, three, etc; first, second, third, etc; next, last, other, another, etc; many, much, (a) few, (a) little, fewer, (the) fewest, less, (the) least, more, most; several, plenty of, a lot of, lots of, a great / large / good number of, a great / good deal of, a large / small amount of; such等

2) 三类限定词的搭配关系

如果一个名词词组带有上述三类限定词，其搭配关系总是按照"前位－－中位－－后位"的顺序排列。例如：

all前the中four后teachers.

all前your中three后books.

all前these中last后few后days.

如果只有上述两类限定词，其搭配关系仍按上述顺序。例如：

half前his中lecture.

those中last后few后months.

several后hundred后guests.

all前other后students.

such前a中misfortune.

some中such后alloy.

由上述诸例可以看出，中位限定词之间和前位限定词之间是互相排拆的，即一个名词中心词之前不可并用两个中位限定词或两个前位限定词。所以，"我的那本书"不是* my that book而是that book of mine，因为my和that同是中位限定词，不可同时并列。但后位限定词的使用却不受此限。除上述those last few months, several hundred guests之外, this last two books, the first two chapters, three other girls, two more sheets, the next few weeks, many more copies, a few more samples, another twenty tons等都是后镁限定词重叠使用的实例。

个别限定词有跨类现象，如such既属于前位限定词，又可归入后位

限定词。由于它只是在such a...和such an...这样的搭配中属于前位限定词，而在与其他限定词(some, any, no, all, few, another, other, many, one, two, etc)搭配时，such则是后位限定词，一律放在上述这些限定词的后面，如some such, any such, nosuch, few such, one such等，因此本书把它归入后位限定词。
