Answer 1

第一题：A
这一题意思是这样的：决定了要戒烟，他把他剩下的香烟都扔了。这里three应该是threw吧。原句还可以这样写：he threw away his remaining cigarettes.he has determined to give up smoking.两句要合并为一句就要考虑到时态，动作先后等，完成时态要作为状语从句，直接去掉主语he和has。这里的remaining作为形容词使用，很常见的用法。
第二题：B
意思是：听说安现在正在非洲做研究，并且下个月就会回来。这里后面半句决定了前半句的时态。说她下个月才会回来，说明她现在还在非洲做研究。现在进行时，B才合乎句意。A，不合语法。C，意思是曾经，句意不连贯。D也是合乎语法的，不过不如B合适，这里如果说前半句加一个例如“for 3 months”这类的表示一段时间的短语的话，D又比B更加合适了。
第三题：B
前面选择have you put ,有点责问的意思。后面表示过去的一个动作，用put.
第一个单词“亲爱的”错了，应该是darling
第四题：D
表示过去一段时间一直都坚持一个动作。意思是我在吃中餐的那段时间里，一直给你留着位子。
第五题：B
“要为考试做准备”是后面“学生没有时间玩”的原因。因此还可以写成“the student didnot have much time to play games because they were preparing for the final exams ”
第六题：A
one 和 the one的区别在于one是泛指,the one是特指,这句里,显然是特指"我除了有人陪同就不被允许穿过的"那条街

Answer 2

第四题选择D因为句子的意思是表达"我已经帮你在餐厅定了位子"A是单指时间,发生在过去,并不代表已经完成;B就是正在进行时C和D都是表示已完成的动作,根据本句的过去时态,所以选D
