Read the letter again and answer these questions.
1. free用作形容词，意为“空闲的”，其反义词为busy“繁忙的”。如：
— Are you free this Friday
这个周五你有空吗？
— Yes, I am. 是的，我有。
[拓展] free还可意为“免费的”。如：
The fruit is for free here today.
今天这里的水果是免费的。
Explanation
2. useful是形容词，是由“名词use (使用) +后缀ful”构成，意为“有用的”。类似结构还有：
help + ful → helpful 有帮助的
color + ful → colorful 绚丽多彩的
[注意] useful是虽以元音字母“u”开头，但其发音为辅音/ju:/，故其前用冠词a，而不用an。如：
It is a useful book. 这是一本有用的书。
3. Lunch is from 12:00 to 1:00...
介词短语 from … to … 意为“从……到……”，用来表述时间、地点等范围。如：
We go to school from Monday to Friday.
我们从星期一到星期五去上学。
It’s far from Beijing to Shanghai.
从北京到上海很远。
4. My classes finish at 1:50, but after that I have an art lesson for two hours.
我学校的课（下午）一点五十分结束，但随后我要上两个小时的美术课。
1）lesson 用作名词，意为“课；课程”。
常用短语：
have lessons 上课
do one’s lessons做功课
Lesson One = the first lesson 第一课
class 和 lesson:
当表示“学校的课”时，class 和 lesson 区别不大，美式英语中常用class, 英式英语中常用lesson。如：
Classes start at 9 o’clock.
(学校)九点开始上课。
(英式英语：Lessons start at 9 o’clock.)
当表示“某种技能、技巧性的课程”时，常用lesson， 较少用class。如：
piano lessons 钢琴课
driving lessons 驾驶课
当表示“教材中的教学单元；课”时，常用lesson。class 则还有“班；班级”的含义。如：
Now, class, please open your books to Lesson 9.
同学们，现在请打开书，翻到第九课。
2）an art lesson for two hours 表示“一节两小时的美术课”， 此句中的介词for表示 “持续某段时间”。如：
Jack usually plays soccer for an hour after school.
放学后杰克通常踢一个小时的足球。
