答案

参考答案:A

解析:戴角膜接触镜后发生的角膜炎可以是细菌性、真菌性、棘阿米巴性等不同类型角膜炎。题干中提供的信息,尚不足对病因作出诊断。考生应当掌握,直接检测病原体,是感染性角膜炎病因诊断的最有力依据。因此,正确答案为A。其他备选答案要么不准确,要么与病因诊断无关,都是干扰答案。

A twisted sense of humor and a strong voice cast(演出人员) make "Open Season" fun for kids and adults. It's a great start for Sony's animation studio.

Boog is a full-grown grizzly(灰熊)bear that has been raised among humans by park ranger Beth. He has a warm place to live, all the food he wants, and is safe from hunters.

However, when he crosses paths with the spastic(大脑性麻痹的) mule deer Elliot, all that changes. Thanks to a series of misunderstandings, everyone believes Boog is dangerous and out of control. Beth is forced to release(释放) him back into the wild.

Once Boog finds himself in the great outdoors, he has no idea what to do. He gets lost, can't find food, and is attacked by unfriendly forest cutters. Boog is forced to rely on the idiotic Elliot to help him find his way back to civilization(文明). But can they make it before open season begins for hunting?

The movie also has a really strong voice cast. Martin Lawrence voices Boog, and his attitude and persona(人格面具)perfectly fit the bear. The same goes for Aston Kutcher as Elliot. Even if you can't stand him in the real world, you'll be surprised how well he brings the annoying deer to life in the movie.
