A.thatB.whetherC.whichD.why

【答案】B

【解析】

句意：未來地球會發(fā)生什么取決于全球變暖是否能得到解決。

考查賓語從句。本句中有what引導的主語從句和depends on后的賓語從句，此處需要填寫賓語從句的引導詞。賓語從句“global warming could be solved or not.”中成分齊全，根據(jù)句意，可知此處可以填寫表示“是否”的連接詞。that連接詞，可以指代人或物，在從句中作主語或賓語；whether連接詞，表示“是否”，可以引導賓語從句；which關系代詞，可以指代物，在從句中作主語或賓語；why連接副詞，表示“為什么”，在賓語從句中作原因狀語。whether…or not…表示“是否”。故選B。
