语法指导
（一）一般现在时：
1. 动词变化：一般现在时主要用动词原形表示，但第三人称单数后要加词尾-s，另外be和have有特殊的人称形式。
在加词尾-s时要注意：
情况 加法 例词
一般情况 加-s reads, writes, says
以ch, sh, s, x, 或o收尾的词 加-es teaches, washes, guesses, fixes, goes
以“辅音字母+y”结尾的词 变y为i再加-es try－triescarry－carries
读音：
情况 读法 例词
在[p][t][k][f]等清辅音后 ［s］ helps, hates, asks, laughs
在[s][z][][t][d]等音后 ［iz］ faces, rises, wishes, watches, urges
在其他情况下 ［z］ plans, cries, shows
2. 一般现在时主要表示：
（1）经常性或习惯性的动作，常与这样的时间状语连用：always, often, usually, sometimes等

eg: Do you like English
Do they have story books
What does she do every evening
Is she at home
Are you good at English
4. 一般现在时的否定式是do not（don’t）或does not （doesn’t）＋动词原形来构成的，be动词做谓语动词只需在be后加not构成否定。
