They know English.动词的种类动词分为四种：连系动词, 实义动词, 助动词, 情态动词1）连系动词：词义不完全，要和后面的表语一块构成谓语。如 be (am, is are)是，sound听起来，look看起来 She is my sister.That sounds interesting .听起来很有趣。2）实
5、义动词，有实际意义的动词，能单独做谓语。如 see, ask, like I like bananas.3）助动词：本身没有词义，帮助实义动词一起构成否定句，疑问句。如 do，doesI dont like chicken .Does he like apples ?4）情态动词；本身具有一定意义，但不能单独作谓语，必须和实义动词一起构成谓语。can,能，会，must ,必须，情态动词后一定要用动词原形。I can speak English .I must find it . 我一定要找到它动词be的用法be 的用法口诀我用am，你用are，is连着他，她，它；单数名词用is，复数名词全用a
