　　So many people use the cell phones so frequently every day. But 47 little is certain about the health effects of its use. Manufacturers 48 that cell phones meet government standards for safe radio-frequency radiation emission, but enough studies are beginning to document a possible 49 in rare brain tumors (脑瘤)，headaches and behavioral disorders in children to cause concern.

In a new trial, researchers asked 47 volunteers to 52 in a project to censure glucose (葡萄糖) consumption in the brain by scanning the brain to see how cells use energy. For both 50-minute scans, the volunteers had a cell phone 53 to each ear. During the first scan, the devices were turned off, but for the second scan, the phone on the right ear was 54 on and received a recorded-message call, although the volume was muted(消音)so the noise wouldn’t bias the results.

　　91. All the information you need to apply for your visa is (可以免费获取).

　　【答案及解析】

　　87. had I felt so excited

　　【解析】本题考查过去完成时及倒装句。第一句话是过去时，第二句话可知其行为发生在过去之前，由此得出第二句话为过去完成时态，其结构为“had done”;第二句第一个词为“Never”否定词，因此句子主谓要倒装。

　　88.could have said somethingthat she might regret later

　　【解析】本题考查过去时态的虚拟语气。第二句是对过去行为一种推测，而事实上行为并未发生，因第一句话的时态是过去时，可判断此句是对过去的虚拟，其主句的构成为“主语+could+have +过去分词”。另外注意本句“后来会懊悔的”这个修饰语，通常翻译成一个简短的定语从句来修饰中心词。

　　89.in focusing on reviewing the lessons

　　【解析】本题考查短语固定搭配。”has / have difficult in doing something”,表示做什么有困难。本题表示无法集中注意力复习功课。“复习功课”通常的表达有 “review the lessons”, “go over the lessons”。

　　90.have heard them communicating with each other in French.

　　【解析】本题考查使役动词的用法以及现在完成时。表示第几次做某事 ，本句谓语是“is”一般现在时，那么主句用现在完成时”have done”;“听到某人做某事”的固定表达为”hear sb. doing sth.”

　　91. available for free

　　【解析】本题固定表达。”be available “，意思为“可得到的，可获得的”;“免费”用介词结构”for free”。
