1Qingfeng tower is in Qiaodong area of Xingtai city . (客观存在)2Bears,snakes and frogs usually look for food in March or April.（一般规律性动作）3The sun rises in the east and sets in the west every day. （自然规律或现象）4Love me, love my dog.（谚语）注意动词变化：只有在第三人称单数用动词的“三单变化”，其他用动词的原形。

三单变化：1.多数在动词后＋s play —plays like —likes（1）直接在动词词尾加-s.ask---asks work---works get---gets stay---stays（2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es.watch---watches wish---wishes fix---fixesdo---does go---goes pass---passes（3）以“辅音字母加- y”结尾的动词，要先变y为i再加-es.try---tries study---studies cry---cries fly---flies2.不规则变化：be---- is are have----has一般现在时的句子转换：（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.例：①陈述句：She is a student.疑问句→Is she a student?否定句→She is not a student.②陈述句：I can swim.疑问句→Can you swim否定句→I can not swim.（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she,he,it）变成问句；在主语后谓语动词前加助动词don’t（I,you,以及复数), doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。
