考查冠詞和短語。句意：如果我們與自然和諧相處，這不是一個(gè)美好的世界嗎？第一個(gè)空中，world表示泛指，應(yīng)用不定冠詞且wonderful發(fā)音為以輔音音素開頭的單詞，故應(yīng)用a;第二空短語in harmony with表示“與....和諧”，中間不加冠詞。故選A項(xiàng)。

must

need

考查情態(tài)動(dòng)詞辨析。句意：你不需要知道作者的名字就能找到一本書。你可以按書名找到這本書。A.must必須，一定；B.need 需要；C. can可能；可能；D.would愿意。根據(jù)句意可知，此處表示一種客觀的可能性，應(yīng)使用情態(tài)動(dòng)詞can。故選C項(xiàng)。

---What language is that guy speaking？I can hardly catch a single word!

---_________He’s from India,so I guess it is Hindi.

Neither I can

Neither can I

So I can

So can I

so can I 表示 我也是這樣，前一個(gè)分句是肯定句的時(shí)候用，前后主語不指同一個(gè)人； neither can I 我也不…，前一個(gè)分句是否定句的時(shí)候用，so I can主要用于加強(qiáng)語氣，其意為"的確如此、確實(shí)如此"前后句的主語指的是同一個(gè)人或物．根據(jù)"I can hardly catch a single word!"可知回答為否定語氣。

考查非謂語動(dòng)詞。句意： 因?yàn)橛幸淮蠖央y題要解決，他感覺像像熱鍋上的螞蟻。本句with +名詞+to do sth,動(dòng)詞不定式表示的動(dòng)作尚未發(fā)生或當(dāng)時(shí)看來尚未發(fā)生。本句表示“因?yàn)橛幸淮蠖央y題要解決”。故選A項(xiàng)。
