1. 用所给单词的正确形式填空。Fill in the blanks.
(1) Happy the Double (nine) Festival.
(2) Here (be) some flowers for you, Mum.
(3) I am learning (paint) in the class.
This is (I) in the class.
(4) (China) people usually buy new clothes before the Spring Festival.
(5) Kitty (watch) fireworks after dinner.
(6) Families (have) a big dinner together on New Year's Eve.
(7) When is National Day? It's on the (one) of October.

(1) ninth (2) are (3) to paint; my (4) Chinese (5) watches (6) have (7) first

1. 重阳节是Double Ninth Festival，此处用nine的序数词ninth；2. 主语some flowers是复数，be动词用are；3. learn to do sth是固定搭配，故用to paint；修饰名词需用形容词性物主代词，故用my；4. 修饰名词people需用China的形容词Chinese；5. 主语Kitty是第三人称单数，一般现在时谓语动词用watches；6. 主语Families是复数，一般现在时谓语动词用have；7. 表示日期“第一”用one的序数词first。

2. 按要求改变句子。Rewrite the sentences.
(1) I like eating noodles.(对画线部分提问)

(2) They like the Mid-Autumn Festival.(对画线部分提问)

(3) It's hot.(改为否定句,句意不变)

(4) New Year's Day is on the first of January.(对画线部分提问)

(5) We like watching colourful fireworks at night.(改为一般疑问句)

(1) What do you like eating? (2) What festival do they like? (3) It isn't hot. (4) When is New Year's Day? (5) Do you like watching colourful fireworks at night?

(1) 对画线部分事物noodles提问，用疑问词What，原句为一般现在时，主语I变疑问句时用助动词do，主语改为you，构成问句。(2) 对画线部分节日Mid-Autumn Festival提问，用疑问词What festival，主语they，助动词用do，构成问句。(3) 原句是It is hot，改为否定句时在be动词后加not，构成否定句。(4) 对画线部分时间提问，用疑问词When，将be动词is提前，构成问句。(5) 原句为一般现在时，主语we改为一般疑问句时用助动词do，主语改为you，动词用原形like，构成问句。
