　A. It　　　　　　 B. As　　　　　　　 C. That 　　　　　 D. What

　答案解析：　此題很容易誤選A，認(rèn)為此處應(yīng)填一個(gè)形式主語，況且It is (well) known to ...也是一個(gè)常用句型，讀起來也很上口，但是選A錯(cuò)了。同學(xué)們仔細(xì)想想看，假若選A，橫線處填一個(gè)形式主語(it)，那么其后就應(yīng)有一個(gè)真正的主語，但事實(shí)上沒有。但是若將句中的逗號(hào)改成that，則只能選A，因?yàn)檫@樣一來，that便成為一個(gè)引導(dǎo)主語從句的引導(dǎo)詞。此題的最佳答案是B，as引導(dǎo)的是一個(gè)非限制性定語從句，可置于主句前(常譯為“正如”)或主句后(常譯為“這一點(diǎn)”)，句意為“正如大家所知，月球每月繞地球轉(zhuǎn)一周”�！�

38.Use an umbrella to _____ you from the rain.　

　 A. stop　　　　　 B. prevent　 　　　　 C. keep　　　　　　 D. protect
