I always remember to turn off the lights, the TV and the fans when I leave the classroom. When I am not using water, I always turn off the tap. I often reuse water, for example, when I finish washing the clothes, I use the water to clean the floor and water flowers. I never use plastis bags. I think saving paper is necessary, so I often make full use of paper. It's important for us to live a low-carbon life to protect the environment.追问各两篇再来点吧回答一般现在时My weekendOn Saturday morning, I usually listen to some classical music, and in the afternoon I take photos in the wild , which is my favorite.

2. 时态在写文章时的用法
一、现在完成时的构成： 1. 现在完成时由助动词"have/has+动词的过去分词"构成。
若主语为三人称单数，则用"has+过去分词"；若主语为非单三，则用"have+过去分词"。have, has在名词或代词后的缩写为"'ve"和"'s"。
如：I have=I've, she has=she's; have not和has not的缩写形式分别是haven't, hasn't。 2. 现以动词wait为例，列表说明现在完成时的构成。
二、现在完成时的用法： （1）表示动作已经完成，但后果或影响仍在。常与already, just, yet等副词连用。
Twenty people have already left.二十人已经离职。 He has not e yet. 他还没有来。
They've just arrived. 他们刚刚到达。 （2）表示过去发生的动作一直持续到现在。
常与for或since引导的一段时间状语连用。 He has lived here for three years.他在此住了三年了。
I have been here since 1976.自从1976年我就一直在这里。 What have you been doing since I last saw you？ 自我上次和你见面以后，你在做什么？ 三、现在完成时与一般过去时的区别： 现在完成时与一般过去时都表示"动作已经发生"，但不同点在于： （1）现在完成时强调这一动作与现在的关系，即对现在产生的结果、影响等，而一般过去时只表示过去的事实，不表示和现在的关系。
He has learned French for three years.他学法语已三年了。 He learned French for three years.他曾学过三年法语。
Who has taken my bag? I cound't find it. 谁拿走了我的包？我找不着了！ He cleaned the house yesterday. 他昨天打扫过房间。 The room is clean, for he has cleaned it already. 房间很干净，因为他已经打扫过了。
（2）现在完成时不可与表示过去的时间副词连用，而一般过去时则可以。 He has done some washing yesterday.(*) He did some washing yesterday.（ ) 他昨天洗衣服了。
四、现在完成时与一般现在时的区别： 在遇到一般现在时与现在完成时在意义上有相似情况时，现在完成时比较强调一个动作从过去到现在的演变过程，语言比较规范，语气也比较正式；而一般现在时着重能力、习惯、心理状态或现在存在的状态等。试看以下例子： 1. (a)中的e from是一个习惯说法，意思是指"他出生在加拿大"。
（b）中的e from不是习惯说法，全句的意思是"他是从加拿大来的"，该句丝毫没有"出生在加拿大"的含义。（b）句使用现在完成时是因为：该动作已经发生完成，但与现在仍有关系，说话者的言下之意可能是"Maybe he can speak English"或者是"So he can tell you something about Canada."。
2. (a)使用的是一般现在时，表示的是不仅刚才唱得好，而且具有演唱才能。全句的意思是"简唱得很好"。
（b）使用的是现在完成时，仅表示刚完成的一次动作，不指平常唱的如何，而是强调对现在的影响。也许说话者的言下之意是"Now she can pass the music test." 3. (a)和（b）都表示"他（刚才）说什么？"但（a）似乎更普遍，（b）则用得较少。
一般现在时表示刚刚过去的情况并不罕见，这是由于说话人着重现在的结果的缘故。（b）则强调"过渡"，时间性较强。
4. 这两句话都比较常用，意义上也无甚差异。如细加区别，（a）比较着重现在的结果，语气比较轻松，可以说是一种现成的说法；（b）则强调从过去到现在的过程，语气比较认真，结构也比较正式。
