答案及解析：
21.第一个空，“apple pie”中“apple”发音以元音音素开头，所以表示“一个苹果派”要用不定冠词“an”;第二个空，“piece”是可数名词单数，这里表示“一块(苹果派)”，“a piece”为常用表达，意为“一块、一份”等。所以选C。
22.第一个空，“teacher”是名词，前面需要用形容词性物主代词修饰，“our”是形容词性物主代词，意为“我们的”，“ours”是名词性物主代词，相当于“our + 名词”，所以第一个空用“our”;第二个空，“talk to”中“to”是介词，后面要接人称代词的宾格形式，“we”的宾格是“us”。所以选A。
23.“festival”意为“节日”;“poem”意为“诗歌”;“guest”意为“客人”;“symbol”意为“象征”。大熊猫是中国特有的动物，深受世界人民喜爱，已成为中国的象征，所以选D。
24.根据答语“我要在社区做志愿者”可知，明天不能去参观天津大学。“can't”表示“不能”，符合语境。“mustn't”表示“禁止”，“can”表示“能够”，“must”表示“必须”，均不符合题意。所以选B。
25.“easy”通常用来形容事情容易;“lazy”形容人懒惰;“boring”形容事物无聊;“fresh”有“新鲜的”之意，葡萄新鲜才会口感好，符合语境。所以选D。
26.由句中的“than”可知，这是今年和去年学习情况的比较，要用比较级。“well”的比较级是“better”，“did better in”表示“在……方面做得更好”。所以选B。
27.“exercise”意为“锻炼”;“cough”意为“咳嗽”;“sleep”意为“睡觉”;“wait”意为“等待”。为了保持健康，在公园进行锻炼是合理的，“keep healthy”与“exercise”逻辑相符。所以选A。
28.“learn to do sth.”是固定短语，意为“学习做某事”，所以这里要用“to swim”。所以选D。
29.“while”引导的时间状语从句，强调主句动作和从句动作同时发生。根据“some visitors came to our class”可知，从句要用过去进行时，其结构为“was/were + 动词的现在分词”，主语是“we”，所以用“were singing”。所以选C。
30.“quickly”意为“快速地”;“loudly”意为“大声地”;“suddenly”意为“突然地”;“quietly”意为“安静地”。因为奶奶听不到，所以要大声说话，“talk loudly”符合语境。所以选B。
31.“takes part in”意为“参加”;“gets on well with”意为“与……相处得好”;“gets into trouble with”意为“与……陷入麻烦”;“keeps clear of”意为“避开”。丽莎是受欢迎的班长，说明她和老师同学相处得好，所以选B。
32.由“next week”可知，句子时态是一般将来时。“Some photos of the moon”和“show”之间是被动关系，即“照片被展示”，所以要用一般将来时的被动语态，其结构是“will be + 动词的过去分词”。所以选D。
33.“until”意为“直到”;“before”意为“在……之前”;“although”意为“虽然”;“so”意为“所以”。离开房间之前应该关灯，“before”符合逻辑。所以选B。
34.宾语从句要用陈述句语序，B选项“how did we get to the Jiefang Bridge”和D选项“when did the Jiefang Bridge open itself”是疑问句语序，排除。根据答语“在五一节的晚上”可知，问句是问时间，所以用“when”引导宾语从句。所以选C。
35.手机丢了应该是安慰对方，“Don't worry”意为“别担心”;“Thanks a lot”意为“非常感谢”;“It sounds great”意为“听起来很棒”;“That's cool”意为“那很酷”。所以选A。
