参考答案及解析：
用括号中动词的适当形式填空——不规则变化1.arise→arose→arisen。所填词在句中作谓语,由was可知,填过去式arose。应注意arise为不及物动词,没有被动语态。
2.draw→drew→drawn。所填词与can一起构成谓语,A conclusion与draw之间为被动关系,应用被动语态,故填bedrawn。
3.dream→dreamt/dreamed→dreamt/dreamed。所填词作谓语,dream这个动作在makes表示的动作之前发生,应用现在完成时,故填havedreamt/dreamed。注意:dream的过去式和过去分词有两种。过去式和过去分词有两种的动词常见的还有: burn→burnt/burned→burnt/burned;learn→learned/learnt→learned/learnt。
4.forgive→forgave→forgiven。所填词与won’t一起构成谓语,acts与forgive之间为被动关系,应用被动语态,故填beforgiven。
5.hang(悬挂)→hung→hung;hang(绞死)→hanged→hanged。第一空用hang的过去式hung,表示"悬挂";第二空应用一般过去时的被动语态,故填washanged,表示"被绞死"。
6.mean→meant→meant。他的存在意味着我在班里有一位意想不到的助教,他的创造力会感染其他学生。所填词在句中作谓语,由空后的had可知应填过去式meant。应注意mean的过去式和过去分词都是meant。
7.permit→permitted→permitted。分析句子结构可知,句子的主语students和permit之间为被动关系,故应用被动语态;又根据语境可知,应用一般现在时,再结合no students可知,填arepermitted。
8.prove→proved→proven/proved。此处为"until you are proved/proven guilty"的省略,故填proven/proved。
9.refer→referred→referred。由从句时间状语yesterday可知,此处应用一般过去时,故填过去式referred。应注意要双写refer的最后一个字母r,再加-ed。
10.rely→relied→relied。所填词与can never一起构成谓语,British weather与rely on之间为被动关系,应用被动语态,故填berelied。
11.seek→sought→sought。所填词在句中作谓语,故填过去式sought。
12.sink→sank→sunk。由yesterday可知,第一空应该用一般过去时,故填sank;第二空考查过去分词作前置定语,表示已完成的动作,故填sunk。
13.submit→submitted→submitted。project与submit之间为被动关系,应用被动语态,故填besubmitted。
14.throw→threw→thrown。第一空所填词作后置定语修饰名词,故填throw的过去分词形式thrown;第二空所填词作谓语,由与其并列的谓语picked up可知,应填throw的过去式threw。
15.wake→woke→woken。空处作谓语,由语境可知,此处表示已经发生的动作,故填过去式woke。
