3分钟学会一个雅思7分句系列，
每次教你学会一个7分句子。
雅思7分作文，
就是日复一日、点点滴滴的积累。
Some people say that the main environmental problem of our time is the loss of particular species of plants and animals. Others say that there are more important environmental problems. Discuss both views and give your opinion.
应对上面这个题目，学生在正文写了如下一句话：
However, it is the rule of Nature, which means that those who fail to adapt to the changing environment will disappear, and in one word, they are vulnerable in nature.
※ 观感上来说，句子后半部分which/that/who几个从句过分堆砌；
※ 两个宾语从句并列时：that those who fail to adapt to the changing environment will disappear和that in one word, they are vulnerable in nature，只有前面一个that可以删，学生不巧删错了；
※ 多余信息：and 之后的内容，其实已经在重复前文了，不如不要；
※ vulnerable形容词修饰they的时候，本身就是在表示“they”的“nature or character”，那么in nature也是多此一举了。
正巧，官方给过范文，其中有这样一句：
Survival of the fittest is nature’s way of ruthlessly allowing weaker specimens to die out, although mankind has also contributed to falling animal numbers through hunting and poaching.
解析：
※ 措辞相当简洁：学生长长的一句话可以浓缩成—— survival of the fittest名词短语、allowing weaker specimens to die out动名词短语
※ 副词的点缀让句子生动起来：ruthlessly
※ 小词的妙用：allow, fall
