Question

1：写一篇关于保护海豚的英语作文
2:在dolphins are members of the whale family which are not fish.中的定语从句定的是哪个词。和语法结构。
3：none和all的区别。

Answer 1

厄。。作文不写了。。。
2.dolphins are members of the whale family which are not fish.先行词是the whale family ，从句 which are not fish用来修饰the whale family，不过我估计应该是 …whale family， which are ….
3.none在句中是否定的。。all是肯定的。。
none表示“什么也没有”，all表示“（三者以上）都”
比如：None of us went there yesterday.昨天我们一个人也没去那里。
All of us went there yesterday.昨天我们都去了那里。

Answer 2

1.我想作文是没人会帮你写的啦,自己随便吹吹就出来咯

2.我与上面滴仁兄们意见不一样,我认为which are not fish修饰的是主语dolphins,因为the whale family which are not fish 不符合逻辑啊~
这样which are not fish 就翻译为"而不属于鱼类"
当然,如果句子改作"dolphins are members of the whale family, which are not fish."就更顺一点咯

3.none是全部否定 相当于not any(一个也没有)
all是全部肯定 而not all是部分否定(没有全部都)
e.g. None of the students are here. 学生们一个也没有在这.
All of the students are here. 学生们全部都在这了.
Not all the students are here. 不是所有的学生都在这.(还有些没来)

Answer 3

2)定语从句修饰的是the whale family
3)在否定句中，none表示全部否定
eg.none of us has(have) money.
我们都没钱
not all of us have money.
我们不是每个人都有钱（有的有钱，有的没钱）

Answer 4

2:这句话的中心词是“the whale family",它后面的部分是修饰这个中心词的！~

Answer 5

which are not fish为定语从句来修饰the whale family 这个先行词的
