Comparative forms of adjectives and adverbs.
当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. tall　句意为“我很矮，但我哥哥很高”。
2. heavy　句意为“我妹妹很瘦，但我很胖”。
3. long　由“我留着短发”及句中表转折的but可知，“我妹妹留着长发”，故填long。
4. loudly　由“我认为在房间里的每个人都能清晰地听见我(唱歌)”可知“我唱得很大声”，故填loudly。
5. outgoing　由下句“他喜欢交朋友”说明“他的哥哥保罗很外向”。
6. better　由than可知此处应用比较级形式，此处表示萨姆打鼓比汤姆打得好，故填better。
7. quietly　由下句中can’t hear her可知“她说得声音很小”，故填quietly。
Ⅱ. 1. better　由than可知应用比较级，good的比较级是better。
2. higher　由than可知应用比较级，high的比较级是higher。
3. more　由than可知应用比较级，many的比较级是more。
4. fatter　由than可知应用比较级，fat的比较级是fatter。
5. more beautiful，mine　由than可知应用比较级，beautiful的比较级是在其前加more；比较对象是你的花园(your garden)和“我”的花园(my garden=mine)，故第二个空填mine。
6. hard-working　此处为“as+形容词原级+as”结构。
Step 7　Homework
Make a survey.
Friends’ names What’s he/she like What does he/she look like
Report like this：John is my friend. He is tall and thin. He has short hair. He is taller than Tony. But John is thinner than Tony...
