9、單位詞的使用
(1) 不可數(shù)名詞表示多少，一般用much, (a) little, a lot of, enough 等詞表達(dá)，要數(shù)1，2，3，4…時(shí)要用"量詞"表達(dá)，最常用的是a piece of (news, advice, furniture, information…)。
(2) 成雙成對(duì)的名詞一般用復(fù)數(shù)，如：a pair of trousers (褲子) / scissors(剪刀) / glasses (spectacles)(眼鏡) / pliers(鉗子)
(3) a couple of表示一對(duì)，或2-3…，如：a couple of days / people / things
(4) 記住以下量詞表達(dá)方式：
a loaf (two loafs) of bread (一個(gè)(兩個(gè))面包)
a burst of laughter(一陣笑聲)
a fit of anger / chill(一陣發(fā)怒 / 發(fā)冷)
a game of chess (一盤棋)
a lump of sugar (一塊方糖)
10、其他應(yīng)注意的數(shù)的表達(dá)形式
1)a three-year-old boy 比較The boy is three years old
2) five thousand people / several thousand people比較 thousands of people
表達(dá)具體數(shù)字時(shí)，thousand不加 "s"，后面不加 "of "; ten, million, billion情況以此類推。
3) One-third of the students have passed College English Test Band IV.
Two-thirds of the students have passed College English Test Band IV.
One-third of the population in this area is living below the poverty line.
(這個(gè)地區(qū)有1/3人口生活在貧困線以下。)
注意：幾分之幾的表達(dá)形式;動(dòng)詞的單復(fù)數(shù)由后面的名詞數(shù)決定。
4) a looker-on 比較two lookers-on(旁觀者) / a brother-in-law比較two brothers-in-law(姻親兄弟)
5) my father, together with (along with / with / as well as my mother and brothers) 結(jié)構(gòu)中，主語作單數(shù)處理，即my father
11、不定代詞的數(shù)
英語中要對(duì) "2 "這個(gè)數(shù)特別敏感：
1) 兩個(gè)中一個(gè)、另一個(gè)： one , the other; 三個(gè)或三個(gè)以上中另一個(gè)：another / any one
2) 兩個(gè)都：both; 兩個(gè)都不：neither; 兩個(gè)中任一個(gè)：either
3) 三個(gè)或三個(gè)以上都：all; 都不：none
4) 不知總數(shù)：一些：some ;另一些：others(有余數(shù))
5) 知道總數(shù)：一些：some ; 另一些 (沒有余數(shù)了)：the others
注意以下表達(dá)方式：each other / one another / one after another / one by one / the other day (過去的某一天)/ some day (今后的某一天) / every other day (隔天)/ on alternative days(隔天)/ someone else (別人) / something (anything, nothing) else (別的事)
實(shí)例：
I'm sorry, I'm a stranger, too. You may ask ______ across the street.
A. another one
B. others
C. the other one
D. someone else
解題思路：雖然A、B、C沒有語法錯(cuò)誤，但D是習(xí)慣表達(dá)方式。
