大学英语六级（2013年12月考试改革适用）模拟试卷392
作文
1.For this part, you are allowed 30 minutes to write an essay on the saying The best preparation for tomorrow is doing your best today. You should write at least 150 words but no more than 200 words.
The Importance of Seizing the Moment There is a famous saying that the best preparation for tomorrow is doing your best today. It tells us that a bright future is awaiting us only if we can seize the moment and try our utmost to achieve our goals.
Beyond doubt, without taking action right now, a goal is only a wish. Without each step you move, you can never ever touch your goal. For a college student daydreaming about scoring high in the CET-6 exam but making no efforts, failure is his only destiny. The same thing can be said of some grown-ups who aspire to gain fame and fortune but never bother to put their splendid plans right into actions.
Therefore, we must keep in mind that every effort today paves your way forward. To pursue our dreams, it is imperative for us to move ourselves into immediate action and do our utmost. Only in this way can we fulfill our dreams.

词汇理解
The United Nations issued a report last week warning that humans are destroying nature at such a rate that life on Earth is at risk. When the report came out, it naturally【C1】________headlines. But obviously it didn\’t hijack the news agenda in the manner of a major terrorist attack or【C2】________of war.
The report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is clear on what\’s at【C3】________and what needs to change. IPBES chair Robert Watson says the【C4】________evidence\\
2.【C1】
G
解析：动词辨析题。空格前面是主语it和副词naturally空格后面为名词headlines，因此空格处应填入动词作谓语，并与headlines 构成动宾结构，When引导的时间状语从句使用了一般过去时，由此可知主句也用一般过去时，故空格处应填入动词的过去式。备选词中符合以上要求的有determined，grabbed和stifled，根据上下文可知，determined“决定”和stifled“压制；使感到窒息”与文义不符，而grab the headline 意为“占据新闻头条，抢头条”，由此确定答案为G项grabbed。
3.【C2】
B
解析：名词辨析题。空格前面是名词短语a major terrorist attack和并列连词or，后面为介词短语of war，因此空格处应填入名词，和of war构成名词短语，与a major terrorist attack 并列，由hijack the news agenda a major terrorist attack可知，空格处填入的名词应该和重大恐怖袭击一样表示某种重大新闻事件，由此确定declaration of war“宣战”符合句意，故B项declaration“宣告，声明”为本题答案。
4.【C3】
M
解析：名词辨析题。空格前面是what’s at，后面是and和另一个 what引导的从句，因此空格处需要填入名词，与at构成介词短语，作is的表语。该句指出政府间生物多样性和生态系统服务科学政策平台的报告清楚地表明了两点，由此推知，空格所在从句和what needs to change一样表示不好的方面，因此，空格处需要填入一个表示负面含义的名词，且能与at搭配。at stake意为“处于危险之中”，由此确定名词M项stake为本题答案。备选的其他名词均与此处句意不符或者不能与介词at搭配，均可排除。
5.【C4】
K
解析：语文推断题。空格前面是定冠词the，后面为名词evidence，因此空格处应填入形容词或动词的分词形式，作前置定语修饰evidence，空格所在句指出evidence呈现“不祥之兆”，紧接着的两句分别从生态系统健康状况和人类生活方方面面对evidence进行具体的举例说明，由此可知，空格处需要填入一个表示证据“充分的”或“确凿的”的词，故确定K项overwhelming“压倒性的”为本题答案。备选的其他形容词和动词分词中，均与此处要表达的证据“充分的”或“确凿的”意思不符，均可排除。
6.【C5】
C
解析：动词辨析题。分析句子结构可知，该句主语是The health of ecosystems，其后的on which we and all other species depend是定语从句，修饰主语，空格前面是is，空格后面为副词的比较级形式more rapidly，因此空格处应填入动词的分词形式与is一起作谓语。由该段第一句和第二句可知，空格所在句说明人类对大自然的破坏危及到哪些方面备选的动词分词中，C项deteriorating“恶化”填入后本句的意思是“生态系统的健康状况正在以前所未有的速度恶化”，故C为本题答案。
7.【C6】
F
解析：动词辨析题。
