一、词汇运用
A. 请根据括号中的中文提示、英文释义、句意或音标,写出句中所缺单词,使句子通顺。
1. Sport helps me ______ (保持) healthy and happy.
2. I like to help my classmates with Maths ______ (难题).
3. I often play Chinese chess with my dad at the ______ (the days except weekdays).
4. Your schoolbag is the ______ colour as mine, but my schoolbag is bigger than yours.
5. Please be ______ (/pə'laɪt/) to our guests.

1. keep
2. problems
3. weekend
4. same
5. polite

1. “保持”在此处作为动词，与“healthy and happy”构成动宾关系，表示“保持健康和快乐”。在英语中，“保持”通常用“keep”表示，且“help sb do sth”为固定搭配，意为“帮助某人做某事”，所以此处应用动词原形“keep”。
2. “难题”在此处作为名词，表示数学上的难题或困难。在英语中，“难题”可以用“problem”表示，且在此处表示复数概念，因为通常不会只有一个数学难题，所以应用复数形式“problems”。
3. 根据英文释义“the days except weekdays”，即“除了工作日的日子”，可以判断此处指的是周末。在英语中，“周末”通常用“weekend”表示。
4. 根据句意“你的书包和我的颜色一样，但我的书包比你的大”，可以判断此处需要填入表示“一样”的词语。在英语中，“the same...as...”为固定搭配，表示“与……一样……”，所以此处应用“same”。
5. 根据音标“/pə'laɪt/”，可以判断此处需要填入的单词是“polite”，意为“有礼貌的”。

(12) playing

(6) ______ (seven) grade now”，这里表示“我在七年级”，应该使用序数词，故填“seventh”。
(7) “Our Science teacher, Mr Brown, is a real
(7) ______ (science)”，根据句意，这里表示“布朗先生是一位真正的科学家”，应填表示人的名词“scientist”。
(8) “He says science is full of
(8) ______ (end) possibilities”，这里需要一个形容词来修饰名词“possibilities”，表示“无尽的可能性”，故填“endless”。
(9) “She's
(9) ______ (friend) and always makes me laugh”，这里需要一个形容词来描述“She”的性格，表示“友好的”，所以填“friendly”。
(10) “Emma is good at
(10) ______ (dance)”，在“be good at”后接动词的-ing形式，表示“擅长做某事”，故填“dancing”。
(11) “and sometimes she
(11) ______ (teach) me cool moves”，根据语境，这里描述的是一般现在时的动作，且主语是第三人称单数，所以填“teaches”。
(12) “Tom, a boy from our class, likes
(12) ______ (play) football so much”，在“like”后接动词的-ing形式表示喜欢做某事，故填“playing”。
(13) “My mum says it's important to stay
(13) ______ (health)”，“stay”后接形容词表示保持某种状态，所以填“healthy”。
(14) “
(14) ______ (jog) helps me feel strong”，这里需要一个名词作主语，表示“慢跑”这项活动，故填“Jogging”。
(15) “Seventh grade has so many changes—
(15) ______ (much) homework and bigger responsibilities”，“homework”是不可数名词，所以用“much”来修饰，表示“更多的作业”。
