[美文欣赏]
But God had an answer for that question too. “Your angel will place your hands together and will teach you how to pray.”
“I've heard that on earth there are bad men, who will protect me?”
“Your angel will defend you even if it means risking her life!”
“But I will always be sad because I will not see you anymore,” the child continued warily.
God smiled on the young one. “Your angel will always talk to you about me and will teach you the way for you to come back to me, even though I will always be next to you.”
At that moment there was much peace in Heaven, but voices from earth could already be heard. The child knew he had to start on his journey very soon. He asked God one more question, softly, “Oh God, if I am about to leave now, please tell me my angel's name.”
God touched the child on the shoulder and answered, “Your angel's name is not hard to remember. You will simply call her Mommy.”
冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。英语中的冠词有三种，一种是定冠词（the Definite Article），另一种是不定冠词（the Indefinite Article），还有一种是零冠词（Zero Article）。
不定冠词a (an)与数词one 同源，是"一个"的意思。a用于辅音音素前，一般读作[e]，而an则用于元音音素前，一般读做[en]。
1) 表示"一个"，意为one；指某人或某物，意为a certain。
A Mr. Ling is waiting for you.
2) 代表一类人或物。
A knife is a tool for cutting with.
Mr. Smith is an engineer.
3) 词组或成语。
