That the earth is round is known to all. 2. That you missed the chance is a pity. 用it 作形式主語的結(jié)構(gòu)A.

37、選擇1. 答案： A 解析： 本題考查學(xué)生對主語從句和賓語從句的穿插理解。在that you know _ in fact you dont賓語從句中缺少一個(gè)能承前啟后的聯(lián)系；同時(shí)又作know和you dont know的賓語,因此只有A項(xiàng),what疑問代詞最充分。 2. 答案： A 解析：Mrs. Black 辭去校長職務(wù)了嗎？沒有，不管誰告訴你的，他都在說謊。Whoever引導(dǎo)的主語從句，相當(dāng)于anyone who。如果選B，則those作主語，謂語應(yīng)用were。 C項(xiàng)引導(dǎo)讓步狀語從句，不能引導(dǎo)主語從句；D項(xiàng)錯(cuò)誤，應(yīng)改為Anyone who told you that。 3. 答案： A 解析： 本題考查主語從句和賓語從句。句意：使我們感到驚異的是，她甚至不知道兩者的區(qū)別在那里。第一個(gè)空所選之詞引起主語從句且在句中作surprise的主語，故用what；第二個(gè)空所選之詞引起賓語從句且在句中作lie的裝語，故用where； 4. 答案： A 解析： 考查名詞性從句。第一格是名詞性從句中缺少賓語，故用what；第二格，表語從句缺引導(dǎo)詞，由于從句中不缺少主要成分，所以不能用what，根據(jù)意思，我想知道的是我怎么能夠在短時(shí)間內(nèi)掌握英語。 5. 答案： C 解
