分析 在自然界中發(fā)現(xiàn)的鋁不是獨(dú)立存在的，因?yàn)殇X和其它元素結(jié)合在一起，通常情況下是和氧在一起．

解答 答案是A．本題考查動(dòng)名詞的被動(dòng)語(yǔ)態(tài)；題干中owing to中的to是介詞，故它的后面應(yīng)跟動(dòng)名詞，這里是its+動(dòng)名詞也就是動(dòng)名詞的復(fù)合結(jié)構(gòu)．combine …with…與…結(jié)合；可見(jiàn)及物動(dòng)詞combine后缺少賓語(yǔ)，its與combine之間是被動(dòng)關(guān)系，故用being combined，故選A．

點(diǎn)評(píng) 首先判斷選項(xiàng)中的動(dòng)詞在句中是以謂語(yǔ)還是非謂語(yǔ)形式出現(xiàn)，然后根據(jù)選項(xiàng)在句中的功能結(jié)合非謂語(yǔ)的基本用法做出合理的判斷．要關(guān)注常見(jiàn)非謂語(yǔ)動(dòng)詞的搭配．

The boss knew that John worked very hard for the years．He thought a moment and said，"Thank you for your criticism，but I have a request．I hope you will do one more thing for our company before you leave．Perhaps you will change your decision and take back your resignation．"John agreed．

Dear He Fei，
Dear He Fei，
I've received your letter and deeply understand how you feel now．However，don't be disappointed or even doubt yourself as you are not the only one who finds it difficult to write well．I suppose the following suggestions might be of some help to you．
To begin with，it is essential to memorize some words，phrases as well as sentence structures，because they are the basis of language learning，just like bricks in a building．Additionally，read English articlesuch as possible and recite the good ones so that you may know how to put them to use whenever possible．Last but not least，keep in mind that there are many things that can't be learnt immediately，so never be frustrated when you fail in one or two exams．
Anyway，just keep going with a strong belief that you can improve your written Englishas long as you never give up．Just as the saying goes："Practice makes perfect．"
Yours
LiJin．
