What time is it?
How many people are there in your family?
How much is your new book?
Where are you from?
二、不定冠词：a和an
使用原则：a用于辅音音素前，an用于元音音素前。
1. 一般情况：
元音字母前用an，辅音字母前用a，如：
an egg an orange an old man
a book a pen a man
2. 首字母为辅音字母但以元音音素开头的单词用an，如：
以h开头的单词为例，h开头的单词多数情况下h发音为/h/，此时前面应用a，如：
a house a horse a high wall
但也有一些情况下h不发音，且单词的第一个音素是元音音素，此时前面就用an，如：
an hour an honour an honest boy
3. 首字母为元音字母但以辅音音素开头的单词用a，如：
以u开头的单词为例，当u发成/?/时，前面应用an，如：
an uncle an umbrella an ugly girl
但也有一些情况下u发成/ju:/或/ju/，是辅音音素/j/开头，此时前面应用a，如：
a university a uniform a usual way
类似的情况还有：
a European girl a one-way ticket
4. 英文字母前：
当a/an后需接单个字母或字母缩写时，此时应根据字母的发音来选择使用a或an。
其中b、c、d、g、j、k、p、q、t、u、v、w、y、z是辅音音素开头，前面应用a，如：
a UFO a KFC restaurant a T-shirt
而a、e、i、o、f、l、m、n、s、x、h、r是元音音素开头，前面应用an，如：
an NBA player an M&M chocolate an FBI detective
【注意】一些表达在全称时前面用a/an，缩写后由于首字母发音的关系，会变成an/a，如：
a European Union country/an EU country 一个欧盟国家
an ultraviolet lamp/a UV lamp 一盏紫外灯
5. 数字前：
当a/an后需接数字时，也应根据数字发音的首个音素来确定是用a还是an。
其中one/w?n/是辅音音素开头，用a，如：
a one-way ticket
eight/e?t/及其派生词是元音音素开头，用an，如：
an 18-year-old boy
eleven/??levn/是元音音素开头，用an，如：
an eleven-storey building
其他数字都是辅音字母及辅音音素开头，用a，如：
a 19-year-old girl a 10-dollarnote a 7-11store
