IR65题 a fictious type of location called a morefa

hejing3263

Def: habitat;place to live, breed

In m	NOT in m
breed seas	leave sometimes
courtship	nests
soc. hier.

Now the question makes a little more sense. I need to find an answer that represents something that always occurs in the morefa and something else that never occurs in the morefa.

Here are the options:

Sleeping: I don’t see anything in my notes about sleeping. This isn’t it.

Occupying the location multiple times: they did mention that some birds leave, yes but I don’t think they said that all of the birds leave and come back. I’ll leave this one for now.

Establishing nests: Oh, yes, the last sentence specifically said they leave to make nests elsewhere. This is the answer to the second part.

Gathering together with members of their own species: Let’s see, they’re both courting and breeding in the morefa, and animals have to breed with members of their own species. So this one is sounding pretty good for the first part.

Territorial competition with members of different species: I don’t have anything in my notes about competition or other species. Nope.

第一空是排除法选出的，迷惑于2和4，但是2是some species不符合must的要求，4可以根据species hierarchy推测。
第二个空，关键句子是The value of observing a morefa when the birds are not present, however—such as prior to their arrival or after they have abandoned the area to establish their nests—is only now becoming apparent. “然而m的观测价值在鸟都不见（如到达前或者放弃在此做巢）后开始显现。” 也就是说当鸟来了或者鸟做了巢的时候，m就废了。所以m里一定不能发生这种事情，是3.

M的价值既可以发生在鸟在的时候又可以发生鸟不在的时候，两个方面的情况。


前面作者一直在说在M这个地方观察鸟类的好处，其中有个前提是，当时在M这个地方有鸟给你观察。那么这句话就是说如果那个地方没鸟怎么办。句子意思大致如下：仅仅从最近开始，即使M没有鸟(破折号表解释)，要么就是鸟儿还没来，要么就是鸟儿已经飞走去筑巢了(破折号表解释)，观察M这个地方依然是有价值的。
