第7题: [单项选择]_______if I had arrived yesterday without letting you know beforehand A. Would you be surprised B. Were you surprised C. Had you been surprised D. Would you have been surprised 参考答案:A 答案解析:本题译文:如果昨天没有提前通知你,我就来了,你会觉得奇怪吗 本题考查的是虚拟语气,从句表示对过去事实的虚拟,而主句含有事情未来发生的意思,且是问对方现场的感受,所以动词形式应与表示现在的时间相一致。
第8题: [单项选择]______ man must fear when traveling in space is radiation(辐射) from the sun. A. Which B. How C. What D. That 参考答案:C 答案解析:[考点] 主语从句。
[句意] 太空旅行时人们所担心的是来自太阳的辐射。
[解析] 根据题意,句中缺少一个连词,来引导主语从句,与is radiation from the sun构成主系表结构;
A. get very little rain B. never have any plants or animals in them C. can all be turned into good land before long D. both A and C 参考答案:A 答案解析:本题只有A项比较客观,即沙漠少雨水,并不是B项描述的沙漠中没有植物,也不像C项说得很快会变成良田。
