Answer 1

B

試題分析：考查時(shí)態(tài)語態(tài)：句意：一個(gè)高科技展覽在國家博物館舉行。我們?nèi)タ纯�。時(shí)間是now，A high-tech exhibition和hold的被動(dòng)關(guān)系，用現(xiàn)在進(jìn)行時(shí)的被動(dòng)，am，is，are+being done。選B。
點(diǎn)評：時(shí)態(tài)題的考查關(guān)鍵是抓住句子的上下文含義和句中的時(shí)間狀語。要根據(jù)時(shí)間狀語來選擇合適的時(shí)態(tài)，在平時(shí)的學(xué)習(xí)中要注意積累有關(guān)時(shí)態(tài)的用法和各種時(shí)態(tài)的特殊之處。這題考查的是過去進(jìn)行時(shí)的用法，時(shí)間now是關(guān)鍵�？磿r(shí)態(tài)別忘了考慮語態(tài)。
