It is difficult to imagine the sea ever running out of fish. It’s so vast, so deep, so S1mysterious. 这里我们首先要知道it’s中的it指代的是sea,这个通过对第一句的分析很容易得出，通过三个so,可以发现空格里的词肯定是像vast, deep一样描述大海的，大海有那些特点？这个时候就可以在脑海里想想了。Unfortunately, it’s not bottomless. Over-fishing,S2 coupled with destructive fishing practices, is killing off the fish and S3ruining their environment.在这句话里，我们不难发现Over-fishing 和destructive fishing practices是并列的概念，可以用and来连接，而我们学过的有with的词组中表达and的一般有along with, together with和coupled with；后面一个空通过killing off the fish不难发现对their environment的动作肯定也不会好，应该和破坏有关，还要注意的是肯定是ing形式。
Destroy the fish, and you destroy the fishermen’s means of living. At least 60 S4percent of the world’s commercially important fish S5 species are already over-fished. 这里通过60和of不难发现是要说明一个百分比，而通过对本句的理解，不难发现是说有60%的鱼的种类被过度捕捞。 Or fished to the limit. As a result, governments have had to close down some areas of sea to commercial fishing.
Big, high-tech fleets S6 ensure that everything in their path is pulled out of water.
这里肯定是一个动词，那就看看Big, high-tech fleets和that everything in their path is pulled out of water.之间的关系，应该是有了big fleets, 才能有后面这种情况的。 Anything too small, or the wrong thing, is thrown back either dead or dying. That’s an S7average of more than 20 million metric tons every year.注意前面的冠词 an, 后面又有of, 并且是对数字的一个比较，S8
When you consider that equals a quarter of the world catch, you begin to see the size of the problem.看要点的时候我们一定要分析前后两句，看看他们之间的关系，是否缺少了什么，而缺少的可能就是我们所需要填写的。这里通过前面一句知道捕捞某种鱼会导致其他海洋生命的死亡，并且给出了数字说明，后后面一句则拿prawns来举例，大家可以想想，这种情况是好还是坏？
In some parts of the world, for every kilogram of prawns caught up to 15 kilograms of unsuspecting fish and other marine wildlife die, simply for being in the wrong place at the wrong time.
True, S9 some countries are beginning to deal with this problem, but it’s vital we find rational ways of fishing, 针对出现的情况我们要做什么？注意true,的确，一般还会有转折通过后面的before …的内容，肯定是要求我们想出办法来解决这个问题，before every ocean becomes a dead sea.S10
It would make a sense to give the fish enough time to recover, grow to full size and reproduce, 注意这里的then后面的动作是捕捞鱼，那意味着前面的对鱼的动作肯定是不捞，不捕捞，能做什么呢？而且通过前面的句子可以知道这是想出来避免鱼被过度捕捞的方法，then catch them in a way that doesn’t kill other innocent sea life.
