英语语法问题
老师几个问题
how can eating meat have a negative effect on the environment?这里的eating是动名词作主语吗?
For a start,all animals,such as cows,pig and sheep,release a gas named methane,which is.这里的主谓用逗号隔开是因为all animals这个插入语吗?
Today many people have come to realize that to help the environment and for the human race to survive,most of.这里的宾语从句后面的to help the environment 是因为逻辑主语是people而用to还是不定式作状语?那 for the human race to survive呢,两个并列状语从句?为什么这么用.
Today many people have come to realize that to help the environment and for the human race to survive,most of us will need to become vegetarian这个是原句还有个版本to help the environment 没有to
另外还有个问题It lacks the vitamins and minerals essential for health.这里是be essential 而lack代替了be动词.

how can eating meat have a negative effect on the environment?这里的eating是动名词作主语
For a start,all animals,such as cows,pig and sheep,release a gas named methane,which is.这里的主谓用逗号隔开是因为such as cows,pig and sheep这个插入语
句子的主语是 all animals
Today many people have come to realize that to help the environment and for the human race to survive,most of.这里宾语从句后面的to help the environment 是宾语从句中的目的状语 其逻辑主语 是宾从中的 主语most of us
那 for the human race to survive也是 宾从中的目的状语 两个状语是并列关系 故用and
.
另外还有个问题It lacks the vitamins and minerals essential for health.这里的essential for health是形容词短语 作定语 修饰 the vitamins and minerals
不是主系表结构 .
再问: 音频里面的内容是 help the environment 并没有to我也不知道是否错误 主语是most of us 那么两个目的状语就是most of us will need to help the environment 和most of us will need for the human race to survive?主语为什么要后置?
再答: 应该有to 没有to错 应该是 most of us will need to become vegetarian to help the environment and for the human race to survive 状语位置 本来就比较灵活 放在前面 或放在后面 都可以 这是不定式作宾语的句子 不属于主语后置 因为主谓宾是正常的语序
