人教版高中英语选修八课件：Unit1-A-land-of-diversity-grammar名词性从

1、快过年了，母亲决定回老家淘麦磨面。今冬把父母亲接过来一起住后，家里的面吃得格外费，勤劳的母亲照顾完父亲和小女儿后，坚持压面条、蒸馍吃，母亲说：“买的面条馍没面味儿。”再加上妹妹一家要从广州回来过年，母亲坚决不让买面，执意要回老家磨面，我知道母亲是想让千里之外的女儿吃上自己亲手磨的面。 在一个晴朗的周末，我早早地陪母亲回了老家。家里虽有邻居的照看，仍缺了点人气。我先帮母亲把院子打扫干净，然后从厢房的粮仓中拿出筛子和薄箩等淘麦工具，看着粮仓靠墙的一排粮缸，我觉得既熟悉又陌生，我已想不起来自己上一次进粮仓是哪一年的事了。打开一缸压得严严实实的麦缸，母亲抓起一把麦子放在手掌间揉搓着，沙沙作响。“这是去

2、年的麦子！”母亲自言自语，像摩挲着自己的孩子，脸上放着光芒。母亲说新麦暴，陈麦好吃养人，家里总存着二三年的麦子。小时候，母亲经常说的一句话就是“家中有粮心里不慌”，随着年龄的增长，阅历的丰富，母亲那简单的话语里蕴含着做人的哲理，只有自己内心富足了，才能在岁月的洗练下沉静、悦己、怡人。 淘麦子就是把麦子倒入一个盛满清水的大盆里，水要满而不溢，麦子要完全沉入水中，只见母亲先用笊篱伸入水中的麦子里充分搅动几圈后，麦子里混杂的麦壳等杂物就浮到了水面上，母亲用笊篱把浮在水面的麦壳捞干净后，用笊篱水平在水面沿盆沿顺时针划圆，水中的麦子就听话地排起队，跟着母亲的笊篱舞动起来，麦子中混杂的小石子等杂物就留在了

3、盆底，等水中的麦子舞得正欢时，母亲灵巧得把笊篱后沿往下一倾，突然停止转动，麦子就鱼贯而入到笊篱中。母亲就这样一笊篱一笊篱地捞满一筛子，由我端起倒入放在小桌上的大薄箩里，用一大块白棉布蒙在手上，插入麦子里反复正反转着圈擦，擦一会儿把棉布掂起来，抖落上面的麦子，拧干再擦，如果拧出来的水浑浊，就把棉布洗干净再擦，直擦到棉布拧不出水，就可以把麦子摊到反铺的竹席上晾晒了。没多大一会儿，两袋麦子就淘完了。母亲一边收拾家什儿一边说：“现在的麦子都是机器收得，干净，不像麦场上打的那么脏，好淘。”看着阳光下泛着金光的麦子，母亲脸上洋溢着幸福的笑容，我的心里也体验到了一种久违的踏实。 在五叔家吃过午饭，唠了一会儿

4、家常，太阳已经偏西，冬天天短，我和母亲就动手收拾，装好麦子往城里赶，天黑前赶到了家。 磨面用的是机器，相对轻松，只是找磨面的磨坊倒费了一番周折，多方打听，才在远郊的一个偏远村子找到了一个小磨坊，幸好麦子湿，又在冬日的小院里晾晒了两天才拉去磨。看着雪白的面粉，母亲脸上的笑容愈发灿烂了。我要把磨好的面粉搬到车上，母亲不让，母亲说：“你没干惯活，别弄脏衣服，咱俩抬着。” 在我弯腰和母亲抬面粉的刹那，母亲的白发像针尖一样刺在我的心上，生生地疼。每次母亲都准确地计算好我回老家的时间，把要带的油、面等菜蔬准备得停停当当，做好好吃的等着我们，而我总是匆匆地回、匆匆地去，不是工作忙，就是孩子要上辅导班，从来没

5、考虑过那菜和面里饱含着母亲多少的艰辛。父母为我们付出了那么多，已经身为人父的我，又为父母做了些什么呢？今年春节可以和父母在一块儿过年了，我想关掉手机、关闭,新课标高二版.选修八,A land of diversity,Unit 1,Grammar,Enable the students to use the Noun Clauses as the subject, object, predicative and oppositive.

12、2.连接代词：what, whatever, who, whoever, whom, whose, which.不仅起到连接一个句子的作用，同时也是从句的一个组成部分。 3.连接副词：when, where, how, why,一、主语从句 简单地说，主语从句就是句子的主语是由句子来充当的。 比如说： 那个问题 是 对的。 ( The question is right. ) “那个问题 ”是这句话的主语，而当把“那个问题 ”换成一句话时，这句话就可以称为“主语从句”。 所以来看这句话： What you did is right.

13、语，所以这句话就被称为“主语从句”了。,二、宾语从句 简单地说，宾语从句就是句子的宾语是由句子来充当的。 比如说： 我知道 他。 （ I know him. ） “他”是 这句话的宾语，而当把“他”换成一句话时，这句话就可以称为“宾语从句”了。所以来看这句话： I know (that) you are a student. ( 那么 you are a student 是一个句子，现在来充当宾语，所以这句话就被称为“宾语从句”了。,特别注明：怎么来判断宾语呢,直接跟在动词（ do ）或是动词词组后面的成分就是 宾语。 如: speak Chinese 这里Chinese 是做 speak 的

(那么 that he is lying 是一个句子，现在来充当表语，所以这句话就被称为“表语从句”了。,特别注明：怎么来判断表语呢,直接跟在be 动词或是连系动词（如 seem , look, remain等）之后的成分就是 表语,四、同位语从句 简单地

15、说，同位语从句就是后面那句话是前面这个名词的具体的内容。 比如说： 我有个通知：明天放假。 ( I have a notice that tomorrow is free. ) 这句话中, tomorrow is free 就是 notice 的具体的内容,从句判断：请指出下列分别是什么从句,1 What we found out from space research is important for us on earth. 2 The fact that we cant travel faster than light means that it will take a long tim

18、式主语和it引导强调句的比较,it作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： It is a pity that you didnt go to see the film. It doesnt interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the windo

19、w,what 引导主语从句时在句时在从句中充当句子成分，如主语宾语表语，而只起连接作用，不做任何句子成分。例如： 1) _you said yesterday is right. 2) _she is still alive is a good thing,It is right what you said yesterday,It is a good thing that she is still alive,What,That,3. what 与that 在引导主语从句时的区别,4 有because引导的表语从句不能 与the reason（做主语）连用,The reason why he
