Classroom OlympicsPPT,第二部分内容:课堂互动探究
词汇点睛
1 none pron. 一个也没有;毫无
[观察] None of us could catch him!我们没有人能够追上他!
None of the guests want to stay. 客人中没有一个想留下的。
[探究] none用于三者或三者以上的人或物,与of连用作主语,指代________名词时,谓语动词要用________形式;指代可数名词时,谓语动词用单、复数均可。例如:
None of the money belongs to me.这些钱不属于我。
None of them has/have seen me before.他们中没有一个人以前见过我。
2 twentieth num. & adj. 第二十(的)
[观察] He came in twentieth.他排第20名。
He was the twentieth in the competition. 他在竞赛中名列第二十。
[探究]以ty 结尾的整十的基数词变为________时,先将y变为________,再加th。
[拓展]基数词变序数词口诀:
基数变序数,th来帮助。“8”少“t”,“9”去“e”,“ve”要用“f”替。遇上几十几,只变个位就可以。1、2、3要特殊记。
句型透视
He did his best, but he kept falling off the pizzas!
他尽最大努力了,但他总是从比萨上掉下来!
[探究] keep doing sth.表示“不断地做某事;一直做某事”。
[拓展] (1)keep sb. doing sth. 表示“使某人一直做某事”。例如:
He kept the boy waiting at the gate.他让那个男孩一直在门口等着。
(2)keep sb./sth. from doing sth.表示“阻止某人/某物做某事”。
例如:We should keep the factory from polluting the river.
我们应该阻止那家工厂污染河流。
