[方法探讨] 暑假让儿子开始整理科学G6，G7里的词汇

汗颜,{:soso_e127:} 里面我只懂几个

上面几个链接是英语词典的网站，我让儿子自己查好字典，把解释COPY出来，看一遍。

最后我还要和儿子一起再来看一遍这个解释，解释里都有不少词汇呢，真是词汇套词汇了。

  厉害，有目标 有计划{:soso_e179:}

都是些不常见的单词！厉害

这得什么水平呀？厉害

呃，都好难啊

天哪，眼晕。宝宝和妈妈都好牛。

认识的单词廖廖无几

这些是原版教材六年级科学课里的词汇，儿子今年9月份要去加拿大读G8，所以，得熟悉这些词汇，其实是学一下G6，G7的科学课。

这个太专业了，大都不认识！{:soso_e110:}

原先我们每天的原版教材（加州和GLENCOE），不学了，开始整理词汇。

看得云里雾里。佩服！！为牛娃加油鼓劲！！

你儿子很厉害啊!

你整理啊？不是他整理么？

学习了，我一直以为lemur是一种类狗动物，原来还是 Primates。
话说LZ的孩子和国外同龄孩子，英语水平是否是同步的阿？

客观地说，同步不太可能，别说我们都回国3年了，就算一直留在加拿大，他的词汇范围，文化理解范围，跟同学还是有差距的，这个差距，或许会在孩子以后的成长中慢慢缩小，但差距是肯定有的。

我追求的也不是百分百的融合同步，毕竟我们还收获了中文呢，只要孩子在学校学习上，能跟上别人（哪怕开始暂时落后），有朋友玩（语言也是需要的，没有语言，何来交流？）初步能达到这个，我觉得就很欣慰了。

为了这个目标，回国3年，我们也一直在努力准备着，包括学原版教材、看原版片（熟悉文化和听力）、看原版书（阅读能力）、听英文故事。。。。。还有我们还参加篮球、冰球、游泳（希望孩子能在运动上，认识一些朋友，不至于成书虫）。

尽力吧，毕竟现在还在国内，去了加拿大后，孩子会怎样适应，我们目前还不好说，尽力准备吧。

这是几岁的孩子？这么牛？

Unlike other vertebrates, mammals have a diaphragm that separates the heart and lungs from the other internal organs, red blood cells that lack a nucleus, and usually hair or fur. All mammals but the monotremes bear live young. Mammals include rodents, cats, dogs, ungulates, cetaceans, and apes.
