,J)基础演练I.单词拼写1.habitats【详解】考查名词。句意：许多物种面临着灭绝的危险，因为他们的栖息地被毁了。根据前文的their，可知这里是复数，故填名词复数形式。故填habitats。2.creatures【详解】考查名词。句意：众所周知，熊猫是珍贵的生物。根据汉语提示“生物”，以及上文precious可知此处应填名词作表语，且主语panders为复数，根据主谓一致原则，此处应填名词复数creatures。故填creatures。3.profits【详解】考查名词。句意：如果销量继续恢复，他们可以雇佣更多的工人，仍然可以获得利润。根据汉语提示“利润”，以及上文make可知此处应填名词构成固定搭配makeprofits，意为“获得利润”。故填profits。4.attacked【详解】考查过去分词。句意：天黑以后不要独自在街上走，否则你可能会被袭击。根据单词首字母和句意“被袭击”以及空格前的get可知，此处应用动词attack的过去分词和get一起表被动，（动词attack和主语you是被动关系）。故填attacked5.measured【详解】考查动词。句意：你的价值不取决于你的外表有多漂亮（你的价值不是有你的外表有多漂亮来衡量的）。根据单词首字母和句意“被衡量”以及空格前的助动词is可知，此处应用动词measure的过去分词measured，和is一起构成被动语态。故填measured。II.单句语法填空1.up【详解】考查动词短语。句意：我们不得不开快一点去弥补我们在波斯顿失去的时间。此处为固定短语makeup（弥补）。故填up。2.illegal【详解】考查形容词。句意：把这些不健康的书卖给16岁以下的人是违法的。根据句意以及空格前Itis可知，此处应用形容词legal的反义词illegal，作表语，符合句意。故填illegal。3.Writing【详解】考查非谓语动词。句意：由于书写流畅，这种无印良品的圆珠笔很受年轻人欢迎。分析句子可知，设空处应填非谓语动词作状语；再结合句意“书写流畅”分析，write与smoothly搭配使用时，应用主动结构表示被动意义，以说明主语的特征或性质。故填Writing。4.weresold【详解】考查被动语态。句意：这些花如此可爱，以至于很快就卖出去了。分析句子可知，设空处应填动词作谓语，而主语和谓语动词之间是被动关系,再结合句意“卖出去了”可知，此处应填一般过去时态的被动语态。此外，theflowers为复数。故填weresold。5.from【详解】考查介词。句意：尼龙是由空气，煤和水制造的。表达由......制造，从成品看不出原材料时用bemadefrom.因此根据句意填from。III.单句写作1.concerningthemeeting【详解】考查介词。表示“关于”应用介词concerning；表示“这次会议”应用themeeting，所以表示“关于这次会议”应用concerningthemeeting。故填concerningthemeeting。2.areallconcernedin【详解】考查时态和短语。分析句子可知，本句为一般现在时，beconcernedinsth“参与......”。故填areallconcernedin。3.AsfarasI’maware【详解】考查固定短语。“据我所知”可用固定结构“asfarasI’maware”来表达，另外，句首单词首字母大写。故填AsfarasI’maware。4.AsfarasIamconcerned【详解】考查固定句型。AsfarasIamconcerned，意为“在我看来，就我所知”，根据句意，故填AsfarasIamconcerned。5.wasremindedofthemistakeImade【详解】考查时态语态和定语从句。分析句子可知，本句为一般过去时，remindsbofsth使某人想起某事，本句为被动语态sbberemindedofsth,themiastake作of的宾语，同时是定语从句的先行词，作made的宾语。关系代词that/which被省略。故填wasremindedofthemistakeImade。IV.七选五1.B2.D3.C4.F5.G【分析】这是一篇说明文。讲述了科学家们对帝王蝶有了更多的认识，这样能更好的保护这种可爱的生物。1.上文“Manyanimalsmovefromoneplacetoanotheratcertaintimesoftheyear.(许多动物在一年中的某些时候从一个地方迁移到另一个地方。)”介绍了动物的迁徙现象，选项B“这种一年一度的运动被称为迁徙。”承接上文，介绍这种现象的专业称谓，引出下文“Theymigratetofindfood,seekapartner,orinsearchofwarmerweather.(它们迁徙去寻找食物，寻找伴侣，或寻找更温暖的天气。)”提出它们迁徙的目的。选项中movement和上文中move，选项中migration和下文中migrate语义一致。故选B项。2.上文“Everyautumn,millionsofthesebeautifulinsectsbeginalonganddifficultjourney.Somehowtheymanagetotravelaround4,000kilometressouthandfindtheirwaytoCaliforniaorMexico.(每年秋天，数以百万计的这些美丽的昆虫开始了漫长而艰难的旅程。不知何故，它们设法南行了4000公里，找到了加利福尼亚或墨西哥的路。)”说明这种昆虫迁徙的原因还不知道，选项D“然而，直到最近才有人知道它们是如何做到这一点的。”承接上文，转折语义，说明最近，有人知道原因了，引出下文“Ateamofscientistshasnowfoundtheanswer.(一组科学家现在找到了答案。)”介绍科学家发现了答案。故选D项。3.上文“Theyhavefoundoutthatthemonarchisabletotellthetimeofday.(他们发现，帝王蝶能够分辨一天中的时间。)”说明帝王蝶有分辨时间的能力，选项C“它用眼睛来测量太阳的位置。”和上文并列，说明帝王蝶有测量太阳的位置的能力，引出下文“Thesetwopiecesofinformation—thetimeofdayandthepointwherethesunisinthesky—allowthebutterflytodeterminethewaytogo.(这两条信息——一天中的时间和太阳在天空中的位置——让这种蝴蝶决定要走的路。)”是对以上两条信息的总结，说明依靠这两种能力，这种蝴蝶就能决定迁徙的路线。选项中measurethepositionofthesun和下文thepointwherethesunisinthesky语义相关。故选C项。4.下文“Sadly,humanactivityisthemainreasonwhythenumberofmonarchbutterfliesisfalling.(可悲的是，人类活动是帝王蝶数量下降的主要原因。)”说明因为人类活动造成帝王蝶的数量下降，选项F“在过去的几年里，它的数量锐减了90%。”和下文存在因果关系。选项中Itspopulationhascrashedbyasmuchas90percent和下文中thenumberofmonarchbutterfliesisfalling语义相关。故选F项。5.下文“Peoplehavebeenrecordingitsmigrationandmakesurethatthereareenoughplantsforittofeedon.Ifthisworks,theremaycomeatimewhenthenumberofmonarchbutterfliesincreasesonceagain.Themoreweknowaboutthislovelycreature,thegreaterthechanceitwillsurviveandkeepitsplaceinthenaturalworldforalongtimetocome.(人们一直在记录它的迁徙，以确保有足够的植物供它食用。如果这一方法奏效，帝王蝶的数量可能会再次增加。我们对这种可爱的生物了解得越多，它就越有可能存活下来，并在未来很长一段时间内保持它在自然界的地位。)”说明人们对这种生物了解越多，就越有可能保护好这种生物，选项G“然而，对帝王蝶行为的研究使人们对这种生物有了更多的了解。”概括说明人们对这种生物有更好的了解，引领本段，说明了解越多，越能更好的保护。故选G项。eq\o\ac(
