不在中国了
我以前住在上海,中国,但是我搬到西班牙了。我离开中国之前,中文说得不错,不过我長时间不在中国,中文變差。为了要練習一下,我有时候发给朋友几个简单的短信还是电子邮件,然后他们用英文回答。这样我们都可以練習一点。现在我决定必须用心学习了,這樣就不會浪费我的以前学的中文。
I used to live in Shanghai, China but I have moved to Spain. Before I left China, I spoke Chinese okay but the longer I'm outside China, the worse my Chinese gets. To practise a bit, I send my friends a few simple messages or emails and they reply in English. That way, we all get to practise. Now, I have decided to study harder, so that I don't lose the Chinese that I learned before.0 votedMarch 21, 20181二氧化碳在地球大气中扮演很重要的角色(play an important role)。 二氧化碳参与了地球上所有生物的形成,并与水和甲烷分子一起产生所谓的“温室效应”。早期(in the early stage)二氧化碳的来源是火山,喷发期间大量的气体释放到大气中。 燃烧有机物质的和生物呼吸也會產生它到空气中(burning organic material and creature breathing make co2 into air)。目前,大气里的二氧化碳佔(occupy)0.04%左右。我们的星球需要二氧化碳,但是大量的二氧化碳对所有的生物都有害,所以人们应该控制大气中二氧化碳的含量。

It means that you can use both words in most situation.
help me = 幫忙我 (it works) = 幫助我 (it works)
you don't help me = 你不幫忙我 (it works) = 你不幫助我 (kind of weird but it works to me)
I think either 幫忙 or 幫助 is [幫(verb) + something], so it is not necessary to distinguish them.
