A buttn n Smart Ck shuld be pressed befre cking. (教材P42 1c)
buttn /ˈbʌt(ə)n/ n. 按钮；扣子
Peter pressed a buttn and the dr pened. 彼得按了一个按钮，然后门开了。Click n the icn with the right muse buttn. 用鼠标右键点击图标。
A buttn was missing frm his shirt. 他的衬衫上掉了一颗扣子。He quickly did up the buttns n his shirt. 他快速系上了衬衣上的扣子。
d up a buttn = fasten a buttn 系上扣子
本句中shuld be pressed为含有情态动词的被动语态，其基本结构为“情态动词+助动词be+及物动词的-ed形式”，否定形式为“情态动词+nt+助动词be+及物动词的-ed形式”。
Students shuld be allwed t make decisins by themselves.学生应该被允许自己做决定。Waste paper shuld nt be thrwn here.废纸不应该扔在这里。
含有情态动词的被动语态变为一般疑问句时，应将情态动词移到句首。Can the sentence be translated this way? 这个句子可以这样翻译吗?
Hundreds f kinds f dishes can be made by Smart Ck. (教材P42 1c)
hundreds f 表示约数，后接可数名词复数，其前不用数词修饰。但 hundred前有基数词或表示数量的限定词时，词尾不加-s，且不与f连用。
Althugh there are nly abut tw hundred teachers and students in this schl, hundreds f sweet mments take place here every day.虽然这所学校只有大约两百名师生，但每天这里都发生许多美好的瞬间。
hundreds f 许多；大量
thusand “千”、millin “百万”和 billin “十亿”的用法与 hundred相同。
