24、19歲大學生的博揚·斯拉聲稱，他將/能在五年中清理掉海洋里大量堆積的塑料袋。本句是說博揚·斯拉的計劃，根據(jù)主句中的made可知，此處應用過去將來時，故填would；同時根據(jù)句意也可以是他相信自己能夠做到，故也可填could。 2．During　解析：考查介詞。句意：博揚·斯拉16歲時在希臘斯庫巴潛泳度假期間，發(fā)現(xiàn)海洋里的塑料袋比魚還要多。根據(jù)句意可知，此處指他在希臘度假期間，故填During，意為“在……期間”。 3．more　解析：考查比較等級。句意見上一題解析。根據(jù)句意及than可知，此處應用形容詞的比較級。故填more。 4．pollution/pollutants　解析：考查詞性

25、轉換。句意：他開始尋找一種解決方法來處理海洋塑料污染(物)問題。設空前有形容詞plastic修飾，且根據(jù)上文描述可知，此處指“塑料污染”或“塑料污染物”，故用名詞pollution“污染”或pollutants“污染物”。 5．what　解析：考查賓語從句。句意：斯拉想出一個他稱之為漂浮的“海洋清理陣列”的主意。come up with意為“想出；提出”，后面跟的是賓語從句，且從句中缺少賓語，結合句意可知填what。 6．itself　解析：考查代詞。句意：……他設計出一種長漂浮物的陣列，目的是讓洋流自己把塑料集中起來。此處的代詞應該指代前面的the plastic自身，故填反身代詞its

26、elf作同位語。 7．was performed　解析：考查動詞的時態(tài)和語態(tài)。本句描述的是已經(jīng)發(fā)生過的事情，應用一般過去時；which引導非限制性定語從句；先行詞為前面的test，和動詞perform之間是被動關系，應用被動語態(tài)。故填was performed。 8．lying　解析：考查非謂語動詞。分析句子結構可知，此處應用非謂語動詞作定語修飾island，它和動詞lie之間是主動關系，故填現(xiàn)在分詞lying。 9．works　解析：考查動詞的時態(tài)。句意：這次飛行員工程是值得的，看看這個想法是否奏效。根據(jù)上一段的內容可知，這項工程現(xiàn)在正在實施，所以要看現(xiàn)在的結果，故用一般現(xiàn)在時。故填w
