教学目标:学生们能识记、拼读Gr,Br辅音连缀,能分音节拼读单词,由易到难,在绕口令、故事阅读中提高Gr,Br辅音连缀的复现率,开阔学生视野,培养学生积极的情感态度。

选取内容:以PEP五年级下册第二单元为蓝本,涉及了小学英语各教材中带Gr,Br的高频单词。

设计依据及建议:本设计依据短课时、高频率、多接触之英语教学原则而做短课时设计。Gr,Br辅音连缀各分在三个短课时中完成,每个短课时设计建议用时三到五分钟。

Brent likes bright blue.He eats bread with a blue plats.But he pains his bread bright blue,too.

Brain likes dark black.He eats bread with a dark black plate.But he pains his bread dark black.

第一次淬火时,淬火感应圈1的长直角边5到齿圈2的倒角端面6的落差为3.5mm,加热时间设定为5.8s,冷却时间设定为10s,冷却时间即喷水时间,也需要控制,时间短易出现屈氏体,甚至是喷水压力也应该有效控制,通常压力控制在0.3~0.45MPa,压力小易导致淬火件金相组织不均匀,易出现屈氏体,降低金相等级。

Can they eat their bread?
