1、2022年考博英语-西北工业大学考前模拟强化练习题（附答案详解）1. 单选题（ ）the most of any advice which you can get from the interviewer and follow up suggestions for improving your presentation and qualifications.问题1选项A.TakeB.KeepC.HaveD.Make【答案】D【解析】考查固定搭配。make the most of “最大限度地利用”。句意：最大限度地利用并且听从面试官给的建议来提高你的陈述方式和素养。选项D符合题意。2. 单选题
2、Being both spoiled and lazy, the boy（ ）everyone else for his lack of success.问题1选项A.criticizedB.blamedC.chargedD.accused【答案】B【解析】考查固定搭配。criticize “批评”；blame “责备，归咎于”；charge “控诉，告诫”；accuse “控告，谴责”。blame 常与for 连用；charge 后跟for；accuse 后接of。根据“for his lack of success”可知选项B符合题意。3. 单选题After the fierce quar
3、rel, they began to have a（ ）loathing for each other.问题1选项A.boringB.reciprocalC.friendlyD.standing【答案】B【解析】考查形容词词义辨析。boring “无聊的；令人厌烦的”；reciprocal “互惠的；相互的”；friendly “友好的；亲切的”；standing “长期存在的”。句意：在那次激烈的争吵后，他们开始相互厌恶。选项B符合题意。4. 单选题There are some earth phenomena you can count on, but the magnetic field,
4、 someday is not of them. It fluctuates in strength, drifts from its axis, and every few 100,000 years undergo, dramatic polarity reversala period when North Pole becomes South Pole and South Pole becomes North Pole. But how is the field generated, and why is it so unstable?Groundbreaking research by
5、 two French geophysicists promises to shed some light on the mystery. Using 80 meters of deep sea sediment （沉淀物）core, they have obtained measurements of magnetic-field intensity that span 11 polarity reversals and four million years. The analysis reveals that intensity appears to fluctuate with a cl
6、ear, well-defined rhythm. Although the strength of the magnetic field varies irregularly during the short term, there seems to be an inevitable long-term decline preceding each polarity reversal. When the poles flipa process that takes several hundred thousand yearsthe magnetic field rapidly regains
7、 its strength and the cycle is repeated.The results have caused a stir among geophysicists. The magnetic field is thought to originate from molten （熔化的）iron in the outer core, 3,000 kilometers beneath the earths surface. By studying mineral grains found in material ranging from rocks to clay article
8、s, previous researchers have already been able to identify reversals dating back 170 million years, including the most recent switch 730,000 years ago. How and why they occur, however, has been widely debated. Several theories link polarity flips to external disasters such as meteor （流星）impacts. But
9、 Peter Olson, a geophysicist at the Johns Hopkins University in Baltimore, says this is unlikely if the French researchers are right. In fact, Olson says, intensity that predictably declines from one reversal to the next contradicts 90 percent of the models currently under study. If the results prov

It certainly points the direction for future research.1.Which of the following titles is most appropriate to the passage?2.The word “flip” (Line 6, Para. 2） most probably means（ ）
11、.3.What have the two French geophysicists discovered in their research?4.The French geophysicists study is different from currently prevailing theories in（ ）.5.In Peter Oslos opinion the French experiment（ ）.问题1选项A.Polarity Reversal: A Fantastic Phenomenon of Nature.B.Measurement of the Earths Magne

14、o direct further research in the inner physics of the earthB.has successfully solved the mystery of polarity reversalsC.is certain to help predict external disastersD.has caused great confusion among the worlds geophysicists【答案】第1题:D第2题:D第3题:A第4题:C第5题:A【解析】第1题:主旨大意题。文章在第一段最后提出问题“磁场是怎么产生的，为什么会如此不稳定？”
15、（But how is the field generated, and why is it so unstable?）；紧接着第二段提到两位法国地球物理学家进行了开创性的研究在一定程度上提供了线索；文章最后一段最后两句话提到“如果这些结果被证明是正确的，地球物理学家将有一种新理论来指导他们去探究地球内部物理学。它确实为将来的研究指明了方向。”（If the results prove to be valid, geophysicists will have a new theory to guide them in their quest to understand the earths inner physics. It certainly points the direction for future research），由此可知选项D“地球物理学的新的研究方法”符合题意。第2题:词义题。文章第二段倒数第二句话提到“虽然磁场强度变化短时间内没有规律，但是好像在每一次两极逆转之前，都有一个不可避免的下降过程”（Although the
