过去经常...

I will use your examples to illustrate my point: Even a native-speaking primary student will often make mistakes using the past tense such as,"I throwed the ball to him."

下面我将用你所举的例子来阐述我的观点：即使是一个以英语为母语的小学生也在使用一般过去时时也经常会犯这样的错误：I throwed the ball to him。

Even though I am not a naturopath I have built my knowledge by visiting many natural practitioners over the past 20 years, I have great friends who are practitioners in the alternate medicine field and often chat to naturopaths at our local health food stores.

即使我不是一个自然疗法学家，在过去的二十年里，我也通过拜访许多的自然疗法的从业者们建立了在自己的知识体系，我有一些了不起的朋友们，他们是替代医学界的从业者，他们经常与我们当地的保健食品店的自然医术者们聊天。

天天除了吃饭睡觉就是上网，当然像周末我会出一下门，我以前很喜欢出门旅行但是现在时间比较紧，几乎没什么空出去，酒吧也不去了，KTV得凑到人头才去下，可能去的最多的地方就是电影院和音乐厅，也经常是一个人去的，觉得自己蛮搞笑的，不过现在有个愿望就是想去下四川，因为几年里自己资助了几个孩子读书，今年四川那边一个孩子小学就快毕业了，我就是想去看下他，可按照现在的状态来说，不知道会不会真会空出时间来过去了。

So you would say in the past tense "I lay on the bed because I was tired."

因此你经常会用过去时态'我躺在床上因为我累了'。

About a Year and half after I had entertain'd these Notions, and by long musing, had as it were resolved them all into nothing, for want of an Occasion to put them in Execution, I was surpriz'd one Morning early, with seeing no less than five Canoes all on Shore together on my side the Island; and the People who belong'd to them all landed, and out of my sight: The Number of them broke all my Measures, for seeing so many, and knowing that they always came four or six, or sometimes more in a Boat, I could not tell what to think of it, Or how to take my Measures, to attack Twenty or Thirty Men single handed; so I lay still in my Castle, perplex'd and discomforted: However I put my self into all the same Postures for an Attack that I had formerly provided, and was just ready for Action, if any Thing had presented; having waited a good while, listening to hear if they made any Noise; at length being very impatient, I set my Guns at the Foot of my Ladder, and clamber'd up to the Top of the Hill, by my two Stages as usual; standing so however that my Head did not appear above the Hill, so that they could not perceive me by any Means; here I observ'd by the help of my Perspective Glass, that they were no less than Thirty in Number, that they had a Fire kindled, that they had had Meat dress'd.

我自从有了这些想法之后，平时就经常会想到这件事，可是因为没有机会付诸实施，因此一直都毫无结果。这样大约又过了一年半光景。一天清晨，我忽然发现有五只独木舟在岛这头靠了岸，船上的人都已上了岛，但却不知道他们去哪儿了。他们来的人这么多，把我的计划彻底打破了。因为我知道，一只独木舟一般载五、六个人，有时甚至更多。现在一下子来了这么多船，少说他有二三十人，我一个人单枪匹马，如何能对付他们呢！因此，我只好悄悄躲到城堡里去，坐立不安，一筹莫展。可是，我还是根据过去的计划，进行作战准备，以便一有机会，立即行动。我等了好久，留神听他们的动静，最后，实在耐不住了，就把枪放在梯子脚下，像平时那样，分作两步爬上小山顶。我站在那里，尽量不把头露出来，唯恐被他们看见。我拿起望远镜进行观察，发现他们不下三十人，并且已经生起了火，正在煮肉。至于他们怎样煮的，煮的又究竟是什么肉，我就不得而知了。
