Now I will introduce them one by one. First is the using of present simple to be. Be 动词用法口诀。I 用 _am_， you用_are_，is_用于他_he_，她_she_，它_it_ ；单数名词用_is_，复数名词全用_are_。变否定，很简单， be 后要把_not_添。变疑问，也不难，把 be 提到_句首_前。特殊变化要牢记，I am 要用 Are you 替。疑问否定任你变，句首大写莫迟疑。The second is the wh-questions. Such as what/where/who subject pronouns. And the last is the use of a/an and plurals. 当一个单词的首字母是元音音素，则用 an; 当一个单词的首字母是辅音音素则用 a. 名词单数变复数的一般规则。一、可数名词都有单数和复数之分。A: 规则的可数名词的复数变化规则：1.一般情况加 s ： 2.以 s 、 sh 、 ch 、 x 结尾的加 es ：3.辅音字母 + y 结尾的变 y 为 i 加 es： 4.以 o 结尾的词 +es 的只有以下词 ：heroes Negroes tomatoes potatoes zeroes/zeros以 o 结尾并且词尾有两个元音字母 +s radios, zoos, bamboos ,(pianos ,kilos photos)5.以 f， fe 结尾的 变 f 或 fe 为 v +es ：半片树叶自己黄，妻子拿刀去杀狼，架后小偷逃命忙。 B: 名词词尾的读音规则：A 在 p t k f等清辅音后读s cups， hats， cakes， roofs B. 在 s z t等音后读iz glasses, faces, roses.C.在其他情况下读作z beds days cities knives.D.以 th 结尾的词原来读 加词尾后多数读 如： mouthmouths pathpaths ; 但是也有不变化的，如： monthmonths, ninthninths, youthyouths.C: 不规则的可数名词的变化规则：小老鼠爬灯台，偷油吃下不来。男人当警察，保护妇女跟儿童；英国人的牙咬了法国人的脚；养了一头日本羊，送给了中国人；养了一头鹿跟鹅，卖给了瑞士人。1.manmen, womanwomen, toothteeth, footfeet, goosegeese childchildren, mousemice,2.单复数相同: sheep, deer, Chinese, Japanese Swiss. 3.以 man, woman 修饰名词构成合成词时,两个词都变化. man servantmen servants.
