连词because的用法
because意为“因为”，后面接原因状语从句。
E.g. She didn’t g t schl because she was ill.
回答why问句时，只能用because，不能用fr或as。
E.g. — Why are yu in a hurry? — Because I want t catch the first bus.
汉语中我们经常说“因为……所以……”，但在英文中有了because就不能再用s。
E.g. Because he was tired, he culdn’t walk there.
比较：because f是复合介词，后面常接名词、代词、 动名词。
E.g. We missed the train because f the heavy traffic. We stayed at hme because f the rain.

在英语中，如果要表示一本书、一只狗、一个苹果等概念时，要用名词的单数形式。
表示名词的单数，要在名词前面加不定冠词a或an。a加在以辅音开头的名词前，如a bk, a pen。an加在以元音开头语的名词前，如an egg, an elephant。
在英语中，如果要表示两本书、三个学生这些两个或两个以上的概念时，要用名词的复数形式。名词的复数形式是在单数名词后加上“-s”或“-es”构成的。
在一般情况下， 词尾加-s，在清辅音后读/s/，在浊辅音、元音及其他一些情况后读/z/。
bk—bks cup—cups student—students
以s，x，sh，ch结尾的词，词尾加-es，读/ɪz/。
bus—buses bx—bxes dish—dishes watch—watches
以f或fe结尾的词，现将f或fe变成v，再加-es, 读/vz/。
shelf—shelves leaf—leaves life—lives wife—wives
以结尾的词，有生命的加-es，无生命的加-s，读/z/。
her—heres ptat—ptates pian—pians z—zs
以辅音字母加y结尾的词，现将y改为i再加-es，读/ɪz/。 以元音字母加y结尾，直接加-s。
baby—babies city—cities family—familiesday—days by—bys way—ways
v元音发生变化。如：man—men, tth—teeth。v单复数同形。如：sheep—sheep, deer—deer。v词尾发生变化。如：x—xen, child—children。v有些名词只有复数形式。如：clthes, trusers。
