人教版选择性必修第四册unit1课文语法填空+课文句子翻译距离高考还有一段时间，不少有经验的老师都会提醒考生，愈是临近高考，能否咬紧牙关、学会自我调节，态度是否主动积极，安排是否科学合理，能不能保持良好的心态、以饱满的情绪迎接挑战，其效果往往大不一样。
以下是本人从事10多年教学经验总结出的以下学习资料，希望可以帮助大家提高答题的正确率，希望对你有所帮助，有志者事竟成！养成良好的答题习惯，是决定高考英语成败的决定性因素之一。
做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。
总之，在最后的复习阶段，学生们不要加大练习量。
在这个时候，学生要尽快找到适合自己的答题方式，最重要的是以平常心去面对考试。
英语最后的复习要树立信心，考试的时候遇到难题要想“别人也难”，遇到容易的则要想“细心审题”。
越到最后，考生越要回归基础，单词最好再梳理一遍，这样有利于提高阅读理解的效率。

选择性必修第四册UNIT 1 SCIENCE FICTIONⅠ.阅读理解Very，very long ago，dogs didn’t exist.There were just wolves of different kinds.“Dogor”，an 18，000-year-old puppy，was found frozen in the permafrost in Siberia near Yakutsk.Permafrost is a layer of ground in Arctic and Antarctic areas that remains frozen.Recently，areas of permafrost are thawing (解冻) as the world has warmed，and uncovering secrets long buried and frozen.Dogor came out of the ground covered with mud and ice，but scientists carefully cleaned him.His head，including his nose，hair，eyelashes，and a mouth full of young teeth，is still very much like it was when he died.Scientists from Sweden have tested him carefully.Their tests showed that the puppy lived 18，000 years ago，that it was a male，and that it was about two months old when it died.But even though the scientists ran two DNA tests to discover whether Dogor was a dog or a wolf，they didn’t get what they wanted.The scientists say that normally it’s fairly “easy to tell the difference”.They now plan on doing a third DNA test.In any case，the results will teach scientists a lot about the history of dogs and when they began to separate from wolves.“We can’t wait to get results from further tests，”said Sergey Fedorov，of the Mammoth Museum of North-Eastern Federal University. Some people believe we may soon get even more information about very old animals.Due to the climate change，the world’s temperature has gone up by 1 ℃，which has led to heat waves，record dry periods，wildfires，record rains，and more strong hurricanes.Since the permafrost in Siberia and other areas is thawing，it’s possible that even more animals will be found，which could help scientists learn more about early history.1.What’s special about Dogor?A.It’s the world’s earliest dog.B.It survived extreme cold.C.It has shown many secrets.D.It is preserved perfectly.2.Which word can best describe the result of the study on Dogor?A.Uncertain.B.Satisfying.C.Unreliable.D.Challenging.3.What does the author want to convey in the last paragraph?A.The rise of temperature benefits animal studies.B.Animals are suffering from natural disasters.C.The climate is worsening.D.Scientists call on people to protect ancient animals.4.Where is the text most likely from?A.A science magazine.B.A biology textbook.C.A novel about animals.D.A report about weather.Chemical engineers at UNSW Sydney have found a way to make“green”ammonia(氨)from air，water and renewable electricity.In a paper published in Energy& En v ironmental Science，the authors say that ammonia synthesis(合成)was one of the critical achievements of the 20th century.When used in fertilisers that significantly increase the output of food crops，it could enable agriculture to sustain an ever-expanding global population.But since the beginning of the 1900s when it was first employed，production of ammonia has been energy-intensive—requiring temperatures higher than 400 ℃ and pressures greater than 200 atm—and all powered by fossil fuels.Dr.Emma Lovell，a co-author of the paper from UNSW，says the traditional way to make ammonia，known as the Haber-Bosch process，is only cost-effective when it is produced on a massive scale due to the huge amounts of energy and expensive materials required and that it produces more CO2 than any other chemical-making reaction.“In addition to the big carbon footprint left by the Haber-Bosch process，having to produce millions of tonnes of ammonia in centralised locations means even more energy is required to transport it around the world，not to mention the risks that go with storing large amounts of it in one place，”says Dr.Lovell.“And we saw tragically in Beirut how potentially dangerous storing ammonium nitrate(硝酸铵)can be.”Dr.Lovell and her colleagues therefore looked at how to produce it cheaply，on a smaller scale and using renewable energy.Their new production method does not rely on fossil fuel resources，and doesn’t give off CO2 either.“And once it becomes available commercially，the technology could be used to produce ammonia directly on site and on demand farmers could even do this on site using our technology to make fertilisers—which means we negate the need for storage and transport.There’s a huge benefit to society as well as the health of the planet，”Dr.Lovell says.5.What do we know about the Haber-Bosch process?A.It does harm to the environment.B.It requires green materials.C.It uses less energy and is cheap.D.It transforms fossil fuels into ammonia.6.Why is the city Beirut mentioned in the text?A.To remind people to protect the environment.B.To give an example of the risk in ammonia storage.C.To convince farmers to transport ammonia elsewhere.D.To stress the choice of a proper centralised location.7.What does the underlined word“negate”probably mean in the last paragraph?A.Inspect.B.Avoid.C.Suit.D.Accept.8.What is the purpose of this text?A.To solve a problem.B.To explain a process.C.To advocate a theory.D.To introduce a method.Ⅱ.完形填空(2024·福建省漳州市高三二模)It was a relatively calm day in the fishing village of Kalk Bay.Several
