初二下学期 Unit 20 Mainly revision
2.take care of的意思是“照料、照顾”,它的同义词组是look after。如要表示“把……照料(顾)好”,则用take good care of…,相当于look after …well。如:My grandfather is ill in hospital. We must take good care of him. (look after him well)
3. He told me not to bring you anything.
该句型“tell/ ask sb.not to do sth.”的意思“是叫/请某人不要做某事”。如果要表示“叫/请某人去做某事”,则用tell/ ask sb. to do sth。
My mother often tells me not to play in the street. Because it’s dangerous.
Li Ming asked me to help him with his studies. I tried my best to answer all his questions.
4. I hope so.
句子的so是用来代替上文所说的话,以避免重复。
5. But she looked at me and cried harder and harder.
句中的harder and harder是英语中一种“比较级 + and + 比较级”的结构,表示“越来越……”的意思。如果形容词或副词的比较级是由more + 形/副词原级构成的话,则应用more and more + 形/副词原级。如:
Our school is becoming more and more beautiful. We all like it.
疑点:
1. Every day he made one of the smaller animals bring him something to eat.
该句中的“make sb.do sth.”是“命令/迫使某人做某事”的意思,是动词不定式作宾语补足语,但不定式符号to必须省略。
2.There is!
这是一句倒装句,是半倒装。如果主语是名词则用全倒装。例如:
There comes the bus. We must go on the bus.
There goes the bell. Let’s go into the classroom.
词汇教学
开学以来,学生接触到的新单词大约有220个。平均每单元的词汇量在37个左右。如何有效地帮助学生记忆和运用所学的单词,是提高学生学习效果的一个重要环节。教材第80课第三部分介绍了运用字谜记忆单词的有趣方法。给学生一个规定的时间,看谁找的单词多。除此以外,教师还可以用一些别的方法帮助学生复习单词。
1.延伸(包括词性和组成短语)如:
care→careful→carefully→take care→take care of→lake good care of
cross→crossed→crossing→across→cross a bridge
take→taking→took→take sth. away→take sth. with sb. →take a seat
wait→waiting→waited→wait for→waiting room
2.快速反应(根据老师的要求,让学生抢答)如:
laugh laughed cry laugh at
stand stood standing sit stand in line (in a queue)
3.接龙游戏
教师先说一个单词,然后由学生接着传下去说,所说单词的第一个字母必须是上一个单词的最后一个字母。如:
garden→nice→empty→yourself→farm→must→tired…
老师可以预先准备一些小礼物,如橡皮、小刀、铅笔等。对优胜者给予一点奖励,提高他们的积极性。这种方法既能帮助他们记忆单词,又能训练他们快捷思维能力。
情态动词教学
前几个单元学生分别学习了情态动词can, may, must, mustn't, have to, need。在本单元第79课第二部分列为专项对上述情态动词进行复习。教师不必只枯燥无味地讲解其含义和语法功能,而应该把他们放在鲜活、生动的语言环境中去运用、体会。结合练习册第79课练习2,教师可以适当补充一些练习,帮助学生复习巩固。如:
