1.invole变成involving
2.endangering变成endangered
3.clear in no condition改成clearly in no condition
4. to expand改成 to expanding

2）endangering 是形容 animals的，但是这里我们要的是形容词，所以改为 endangered
3）clear 改为 clearly， 变为副词，“很明显地”是形容 "in no condition to move。。。" 这个动作，所以改为clearly
4) 这题原则与第一题一样，改后面为一个物，变 to expanding

收起

1.错误在invole,是拼写错了，应该是involve。不要改形式，to的后面是动词的原型
2.错误在endangering,要改成形容词，应该是endangered
3.错误在clear in no condition,应该是 unclear in no condition.
4.错误在to expand,应该改成 expanding， 去掉to.
