答案
51.答案為B。第一段講到鯨魚很像陸地上的哺乳動物，最后一句舉了一些例子來說明這一點。sign的意思是符號，特征，鯨魚具有陸地上哺乳動物的一些特征，故選B。
52.答案為c。something is built into的意思是把裝入，這里指鯨魚生有巨大的氣力。其他幾個選項意思上講不通。
53.答案為A。只能用介詞at，不能用其他介詞。
54.答案為D。rate表示速度，從上下文來講，選D意思才講得通。
55.答案為B。此題亦必須根據(jù)上下文的意思來推測選哪個詞。鯨魚被惹怒后會攻擊船只，所以選B。
56.答案為C。這里是一非限定性定語從句，關(guān)系代詞作 主語，用which，故選C。
57.答案為A。have + something+過去分詞是一固定結(jié)構(gòu)，此處只能選A。
58.答案為D。本題所在句子為該段主題句，談的是鯨魚的潛水能力。鯨魚的潛水能力很強，能下潛到很深的地方，科學(xué)家們不解，所以說是個迷，故選D。
59.答案為A。雖然本題的幾個選項都能與food搭配，但從上下文意思來講，只有A正確。
60.答案為B。空格后面的名詞是pound，重量單位，據(jù)此可以判斷選B，因為其他幾個選項不能和pound搭配。
61.答案為C。呆在水下要用動詞remain，其他幾個動詞放入空格處意思講不通。
62.答案為D。此題也必須在讀懂上下文意思的基礎(chǔ)上才能作出判斷，這里指鯨魚聚集氧氣，故選D。
63.答案為B。上文談到鯨魚為什么能夠在水下承受巨大的壓力，科學(xué)家們還沒有找到答案。選項中的deterrmine的意思是確定，此詞放入空格處意思講得通，其他幾個選項講不通，故選B。
64.答案為A。special雖然和幾個選項都能搭配使用，但只有選項A意思上講得通，故A為正確答案。
65.答案為D。此題亦需根據(jù)上下文的意思作出判斷。automatically的意思是自動地。
