Sentence structure The simple past tenseThe present perfect tenseThe present perfect cntinuus tenseThe past perfect tense
The past simple tense：焦点只在过去
We use the past tense t talk abut:① smething that happened nce in the past: I met my wife in 1983. They gt hme very late last night.② smething that happened several times in the past: When I was a by, I walked a mile t schl every day.

一般过去时表示1. 过去某个时间里发生的动作或状态。2. 过去习惯性、经常性的动作、行为。3. 过去主语所具备的能力和性格。
一般过去时最明显的现象就是常由表达过去之时间的副词或副词短语来作时间状语。yesterday (mrning,afternn,evening)the day befre yesterdaylast night (week,Sunday,weekend,mnth,winter,year,century 世纪）this mrning/afternn/eveningwhen引导的状语从句（动词过去时） just nw刚刚the ther day = a few days agat the age f 10 （过去年龄段）in the ld daysat that timein+整十数年份+s（⋯世纪⋯年代）
The present perfect tense：过去+现在
现在完成时表示：1.过去发生的某一动作对现在造成的影响或结果或到现在为止已经发生或完成的动作。2.表示过去发生的、持续到现在的动作或状态。
时间状语 already, just, s far, in the past few , yet, ever, recently, lately, up till nw, these days/years...
①表示从过去某时开始一直持续到现在的动作，并且还将持续下去。如： It has been raining fr tw hurs. (现在还在下,暂时不会停止) Jack has been feeling very well recently. (现在也如此，暂时不会停止)③表示一个从过去开始延续到现在，可以包括现在在内的一个阶段内，重复发生的行 动，如：She has been playing tennis since she was eight.③现在完成时强调动作行为的结果、影响，而现在完成进行时只强调动作行为本身：Tm's hands are very dirty. He has been repairing the car.（他一直在修车，强调动作本身）The car is ging again nw. Tm has repaired it.（他修好了车，强调结果）
The present perfect cntinuus tense：过去+现在+将来
The past perfect tense：过去的过去
过去完成时表示在某一时间或动作之前已经发生或完成了的动作。它表示动作发的时间是“过去的过去”。表示过去某一时刻可用by、befre等构成的短语，也可用when、befre等引导的从句，或者通过上下文表示。如：By the time I went utside, the bus had already left. 我到外面去的时候，车已经开走了。When I gt t schl, I realized I had left my backpack at hme. 当我到达学校的时候，我意识到我把背包落在家里了。

〖解析〗take place 不能使用被动语态；in the past few years在过去的几年里，表示从过去持续到现在，所以用现在完成时态

〖解析〗句意：他吃过早饭去了图书馆，然后一直在那里写论文。表示动作从过去一直持续到现在，强调动作本身，所以用现在完成进行时态。

〖解析〗句意：多亏了这个国际协议，自从1990年到现在非法猎杀少多了。表示动作从1990年到现在，强调结果，所以用现在完成时态。

〖解析〗句意：我们一行三人去年夏天在欧洲游览了大约一个月。只关注过去的时间发生的事，与现在无关，所以用一般过去时态。

自然遗产不应该对公众开放的论点： 1. 自然遗产地的自然资源被过度使用，超出了自然能够承受的能力，久之，自然遗产会遭到永久性的破坏2. 游客产生的污染会对野生动物和自然环境造成破坏3. 一些游客的不文明行为会对自然遗产造成永久性破坏
Natural heritage sites shuld nt be pen t the public because crwds f visitrs can cause damage t them. First f all, natural resuces will be excessively used t satisfy the visitrs' needs, such as fresh water and ther raw matrials, which is ttally beynd the envirnment's ability t recver. Anther prblem that visitrs bring t us is pllutin, including nise, air emissin, slid waste, chemicals and littering. These can nt nly disturb the nraml life f wild animals but break the balance f natural envirnment. Last but nt least, sme visitrs even cnduct "uncivilized turist behavir," including climbing trees, picking flwers and fruits, damaging plants, feeding animals, etc. These bad behavirs smetimes can casue permanent damage t the natural heritage sites.As far as I'm cncerned, in rder t cnserve them better, natural heritage sites shuld nt be pen t the public.
