______ they grow they make sure that what is left in the ground after harvesting______ a natural fertilizer for the next year’s crop.
A．Whatever; becomeB．Whichever; becomeC．Whatever; becomesD．Whichever; becomes
C

試題分析：考查狀語從句和主謂一致。句意：無論他們種什么，他們確信在了收獲后留在地里的都會成為為了來年的收成的一中天然的肥料。根據(jù)：whichever無論哪一個（有固定范圍），而本句沒有范圍，所以排除B和D，第二個空根據(jù)主語是what從句，謂語動詞有表語而定，表語a natural fertilizer f，單數(shù)，所以一個是becomes ,所以C正確。
