82. I think that the meal is well worth $80 without a discount(沒有折扣的情況下值80美元).

【點(diǎn)評】well worth，“值”，后跟動名詞或名詞；discount 折扣。

83. Facing the fierce competition from other companies(面對來自其他公司的激烈競爭), the automobile manufacturer is considering launching a promotion campaign.

【點(diǎn)評】橫線處要填的是一個非謂語從句，根據(jù)句意可知前后主語都是the automobile manufacturer，因此用現(xiàn)在分詞形式。

84. As far as hobbies are concerned, Jane and her sister nearly have nothing in common / hardly have anything in common(幾乎沒有什么共同之處).

【點(diǎn)評】have something in common有共同點(diǎn)，注意表示否定時副詞的使用。

85. Only after many failures have I realized that I cannot succeed with luck merely(我才認(rèn)識到僅憑運(yùn)氣是不能成功的).

【點(diǎn)評】本題考查only位于句首的倒裝。這里強(qiáng)調(diào)的是過去的事情對現(xiàn)在造成的影響“不能成功”，因此應(yīng)用現(xiàn)在完成時態(tài)。

86. But for the survival instinct which nearly all creatures have, more species would have been extinct from the earth(更多的物種就可能已經(jīng)在地球上滅絕了).

【點(diǎn)評】but for，“要不是，如果沒有”，這里考查虛擬語氣，后面應(yīng)該用would + have done的形式，強(qiáng)調(diào)這種非真實(shí)的虛擬對將來可能發(fā)生的情況的影響。
