He is eating lunch.→ He is not eating lunch. → Is he eating lunch?
六. There be结构
1. There be句型主要用以表达“某处有某人（某物），强调存在”其基本结构为“There be＋某物（某人）＋某地”，有时为了强调地点，也可把地点状语放在句首。
There is a book on the desk.
On the desk there is a book.
2. have表示“某人拥有某人或某物，强调拥有和所属关系”。
The man has two cars.
3. There be句型中的就近原则，即be和距其最近的主语保持一致。
There are some pens and a book on the floor. =There is a book and some pears on the floor.
七. 选择疑问句
选择疑问句是指说话人提出两种或以上的情况，让对方选择是哪一种，两个选择部分用or连接。选择疑问句不用yes或no来回答，直接在两个选择里选一个回答。
---Is she tall or short? ---She is tall.
---Can you play the piano or play the guitar? ---I can play the piano
八. 名词
1. 名词单数变复数规则
在英语里面，名词分可数名词（countable noun）和不可数名词（uncountable noun）。不可数名词没有单复数之分，用时只当单数词用；可数名词有单复数之分，一个的前面要用a或an，eg: a pencil, a basketball, a dictionary, an egg, an ID card，而复数即两个或两个以上的要作相应的变化，情况如下：
(1)一般的词在单数词后直接+“s”
book→books，pen→pens，car→cars，map→maps，cartoon→cartoons
(2)以s，x，sh，ch结尾的词+“es”
box→boxes，watch→watches
(3)以辅音字母+y结尾的名词去掉“y”，改成“i”，再加“es”
family→families，comedy→comedies
(4)以f或fe结尾的词，先去掉f或fe，改成“v”再加es
knife→knives，wife→wives，handkerchief→handkerchieves
(5) 特殊词，特殊变化，需单独记：
child→children，man→men，foot→feet，woman→women
tooth→teeth，sheep→sheep，deer→deer
2. 既是可数名词又是不可数名词的单词
chicken当“鸡肉”讲时是不可数，当“小鸡”讲时可数；
room当“空间”讲时不可数，当“房间”讲时可数；
fish当食物用“鱼、鱼肉”讲时不可数，当“鱼的种类”讲时可数；
hair泛指“毛发”时不可数，当“一根或几根毛发”讲时可数；
sound意思是“一般性的声音”时，不可数，指“一次发出的声音”时可数；
paper当“纸”讲时不可数，当“试卷”、“论文”、“证件”讲时可数；
time当“时间”讲时不可数，当“时代、倍数、次数”讲时可数；
exercise泛指“锻炼”时不可数，当“练习、做操”讲时可数
九. 一般过去时
一般过去时表示在过去某个时间所发生的动作或所处的状态（与现在无关） 。常与yesterday, last week, in 1989, just now, a moment ago, the other day等过去具体时间状语连用。
