当堂达标（见导学案“当堂达标”）
答案与解析：
Ⅰ. 1. suddenly　句意：当我横穿街道时，一辆车突然驶过来。suddenly意为“突然”，符合句意。
2. heavily　根据后面“地上有太多的水”可推知，此处意为“昨晚下了如此大的雨”。heavily用来形容雨、雪下得很大。
3. began　本句表示当一个动作正在进行时，另一个动作发生。主句用一般过去时，时间状语从句用过去进行时。
4. off　根据后面I was late for school可知，“我”迟到了，故此处意为“我的闹钟没响”。go off意为“（闹钟）发出响声”，故填off。
5. pick　pick up the phone是固定短语，意为“接电话”，didn’t后接动词原形，故填pick。
Ⅱ. 1. was watching　由at nine last night可知句子应用过去进行时，其构成为：was/were +现在分词；主语he是第三人称单数，因此要填was watching。
2. were，doing　由提示词then可知句子应用过去进行时；因为主语the twins是复数，因此谓语要用“were+现在分词”。
3. Was，drawing；wasn’t　由问句句意“老师进来时莉莉正在画一只猫吗？”可知，此处表示一个动作发生时另一个动作正在进行；when引导的时间状语从句用一般过去时，因此主句应用过去进行时。由答语no可知是作否定回答，因此要用wasn’t。
4. Were，having　由at that time 可知句子应用过去进行时，本句主语为you，be动词应用were，注意句首单词的首字母应大写；have的现在分词为having。
5. is playing　由提示词now可知，句子应用现在进行时，其结构为：am/is/are +现在分词。由主语Jim可知be动词应用is，play的现在分词为playing。
Ⅲ. 1. A　pick up意为“捡起，接（某人）”；give up意为 “放弃”；pick up和give up都为“动词+副词”型短语，人称代词作宾语时放动词和副词中间，故排除C、D两项。根据从句“when he saw a wallet on the ground（当他看到一个钱包在地上时）”可知，他立刻捡了起来，pick up符合句意，故选A。
2. D　get off“下车”；take off“（飞机）起飞，脱下（衣服）”；go away“离开”；go off“（闹钟）发出响声”。由“今天早上我上学迟到了”可知，“因为我的闹钟没有响”。故选D。
3. C　根据后句“It made me scared.（它让我恐惧）”可知，“我”刚才听到了一种奇怪的声音，strange意为“奇怪的”，符合句意，故选C。
4. C　句意：多么大的雨啊！雨下得如此大。根据句意可知第一个rain为名词，故用形容词修饰；第二个rain为动词，故用副词修饰，故选C。
5. A　begin to do sth. 意为“开始做某事”，故选A。
Ⅳ. 1. was，doing　2. was cleaning　3. was raining
4. were watching　5. was doing my homework
Ⅴ. 1~5　CBAED
