Steve Jones is an environmental expert who tries to keep animals and plants from becoming endangered.斯蒂夫·琼斯是个环保专家,他的工作是努力保护动植物不受危害。  句中的who引导一个定语从句,修饰expert。此外句中的keep ... from doing sth.意为“阻止/防止……做某事”。例如:  The heavy snow kept us from going out.大雪使我们不能出去。  Keep还可用于下列句型:  1. keep doing sth. 意为“继续干某事”,表示不间断地持续干某事,keep后不能接不定式或表示静止状态的v-ing形式,而必须接延续性的动词。例如:  He kept working all day, because he wanted to finish the work on time.他整天都在不停地工作,因为他想准时完成工作。  Keep passing the ball to each other, and you’ll be OK.坚持互相传球,你们就行。

 2. keep on doing sth. 意为“持续做某事”。例如:  The pupil kept on asking me the same question.这个学生不断地问我同一个问题。

I kept on thinking about the match in the afternoon.我总是想起下午的那场比赛。

2. When the habitat of a species is changed or destroyed, the animal or plant has to either adapt to the change or find a new home. 当某个物种的环境发生变化或遭到破坏,那种动物或植物就必须适应这种变化或另觅栖息处。

either ... or 用作并列连词,用来连接句中的同等成分,表示二者取一,意为“不是……就是……,或是……或是……”。例如:  One of them will have to go, either Tom or Mary. 他们之中只能去一个,或是汤姆或是玛丽。

Either you must improve your work or I shall dismiss you. 不是你改进工作就是我解雇你。

either ... or ... 连接两个主语时,其谓语动词应与邻近的一个主语在人称和数上保持一致,这就是我们通常说的“就近原则”。例如:  Either you or I am going there tomorrow. 明天要么你去那里,要么我去那里。  注意: 如果把上句变成一般疑问句,助动词形式与主语you保持一致,所以要用are提问,而不是am。例如:  Are either you or I going there tomorrow? 明天是你还是我去那里?  Either you or he has lunch at school. 其一般疑问句应为: Do either you or he have lunch at school? 是你还是他在学校吃午饭?  若要对either ... or ... 句型进行否定时,只需把either ... or ... 换成neither ... nor ... 即可。例如:  Either you or she is good at drawing. 变为否定句应为: Neither you nor she is good at drawing. 你和她都不擅长绘画。
