a和an是不定冠词，修饰可数名词单数形式，表示泛指一个…；an用于元音音素开头的单词前；the是定冠词，修饰名词表示特指。
根据句意可知，第一个空特指树下面的女孩，用the；第二个空表示“一个…的女孩”，且honest中第一个读音是/ɒ/，故用an修饰，选A。
2．C解析：C【解析】【分析】【详解】句意：在周末我经常弹钢琴。
a和an是不定冠词，修饰可数名词单数，表示泛指“一个…”，an用于元音音素前；the是定冠词，修饰名词表示特指。
空后的piano是钢琴，在乐器的前面必须加定冠词，故应选C。
3．D解析：D【解析】句意：——你的表弟长得什么样？——哦，我的表弟是带有短黑发的一个11岁的男孩。
他也是很有趣的，并且他喜欢讲笑话。
11-year-old是复合形容词，11是以元音音素开头的，这里表示泛指用不定冠词an，短语tell jokes表示讲笑话。
根据题意，故选D。
冠词作为一种虚词，在英语中只能和名词一起使用。
英语中的冠词分为不定冠词和定冠词。
点睛：1.不定冠词的用法不定冠词有两个，a 和 an。
a用在辅音开头的单词前面；an用于以元音开头的单词前。
如：a book, an apple。
1）不定冠词用在但数可数名词前表示“某一个”。
如：There is a policeman at the door.门口有个警察。
2) 不定冠词用在单数可数名词之前，表示“任何，每个”。
如：A car must be insured.汽车一定要上保险。
A soldier must obey orders.军人必须服从命令。
4．A解析：A【解析】【分析】【详解】句意：“如果你足够关怀生者，为你，为我创造一个更美好的世界。
”拯救世界这首歌里的歌词真正地感动了我。
从句意可知这里表示“活着的人”，所以用the living; 第二个空后面是better place，这里表示泛指“一个更好的地方”所以是a better place, 故选A。
5．D解析：D【解析】【分析】【详解】句意：——你好，乔伊斯，你很忙。
我能帮你吗？——非常感谢，不过我能应付。
hand以辅音音素开头，前面用不定冠词a表示泛指，give sb. a hand帮某人一把；and表示并列关系；or表示选择关系；so表示因果关系，but表示转折关系，根据句意可知，这里不需要对方提供的帮助，因此用but表示意义上的转折，答案为D。
6．A解析：A【解析】【分析】【详解】句意“-梅梅，你有弟弟或妹妹吗？-没有，但是我的父母告诉我一个新的弟弟或妹妹马上就来了”。
根据句意可知，表示特指“一个”，且new以辅音因素开头，故选A。
7．B解析：B【解析】【分析】【详解】句意“-看！正在和杰克在那说话的小男孩是谁？-是鲍勃，我的表弟，他是一个诚实的小男孩”。
第一空处特指“正在和杰克说话的小男孩”，用the，排除A和D。
第二空后honest为元音因素开头，用an，故选B。
【点睛】a用于以辅音音素开头的单数可数名词前；an用在元音音素开头的单数可数名词前。
