I cover the top with a piece of cardboard and hold it there. 我用纸板把上面盖住然后托住它。【用法】 句式 cover…with…意为“用……覆盖……”，类似句式be covered with 表示“被……覆盖”，这是一个系表结构。【举例】①My mother covered the table with cloth. 我妈妈用布把桌子盖住了。②The bed is covered with paper. 床上盖满了纸。2. I am so sure of my theory that Brian can do the experiment over your head and I know you won’t get wet. 我对布莱恩在你头上做实验的理论很有把握，并且你不会湿的。【用法】这句话中的句式be sure of意为“对……有把握”；that Brian can do the experiment over your head是定语从句，修饰前面的名词theory。【举例】①Are you sure of this matter? 你对这件事情有把握吗？②This is the book that I borrowed from the library. 这是我从图书馆借的书。3. It is strong enough to hold the water. 它力量很大足以把水托住。【用法】句中的enough to do…意为“足以……做某事”，这里的enough起副词作用，用在形容词或副词后作状语。【举例】Allan is old enough to go to work. 艾伦到上班年龄了。
