这篇文章在前面的3a中就有相应的提示信息，这里又有句子提示，所以解题关键就是要弄清楚每个句子后面要接的内容。
Whales are …此句子，be动词接形容词，描述“鲸”的外貌，用句子：Whales are huge.还可以加一句：Some kinds have teeth.
They live in... 此句中live in + 居住地点，根据前面提示有：They live in the sea.
They can... 此句中can是情态动词，后接动词原形，根据前面的提示，有They can Jump high out of the water.
One interesting fact is ... Another interesting fact is ... 结合前面的提示有：
One interesting fact is that Whale parts are sold to make things like candles. Another interesting fact is that they can sing songs.
Some kinds of whales are in danger because... because后面接完整的句子，根据3a的提示，有：Some kinds of whales are in danger because humans catch whales for meat,fat and oil.
We should protect whales from... 我们应该保护“鲸”远离。。。。。。，结合事实有：We should protect whales from dying and being caught.
I think people should \ shouldn’t ... 结合前面3a 的提示，有I think people should learn more about whales and make rules on whale protection. And they should stop putting rubbish into into the sea. They shouldn’t kill the whales for their teeth and oil.
全部连起来，得到以下文章：

Adjectives（形容词） Comparatives（比较级） Superlatives（最高级）

解题思路：复习形容词副词比较级、最高级的构成方法——一般情况，加er或者est；以不发音的字母e结尾的形容词或副词，加r或者st; 以重读闭音节结尾的单词，如果词尾只有一个辅音字母，应该先双写这个辅音字母再加er或者est;其它双音节词和多音节词，比较级在前面加more，最高级在前面加est.
参考答案：
high-higher-highest dangerous - more dangerous - most dangerous
long - longer - longest popular - more popular - most popular
