【3】考查there be句型。句意：有八個行星太陽圍著太陽轉(zhuǎn)。根據(jù)空后的eight planets可知此處系動詞應該用復數(shù)。描述的是客觀事實，時態(tài)應為一般現(xiàn)在時。故選B。

【4】考查名詞詞義辨析。句意：在地球上有人類、動物、植物和其他種類的_________。plant植物；life生物；animal動物；nature自然。由句意可知此處表示地球上還有其他種類的生物，應用life。故選B。

【6】考查名詞詞義辨析。句意：其他七個行星都沒有像地球一樣的_________。lesson課程；house房間；expression表達；environment環(huán)境。本段四、五句描述的都是地球上的環(huán)境狀況，所以此處表示其他星球沒有像地球一樣的環(huán)境，應用environment表示。故選D。
