第一单元 生活智慧与时代精神
是一种客观存在(但不是客观实在,因为客观实在是相对于
意识而存在的),哲学要进行反思,既需要对实践活动进行
反思,也需要针对以往的某些思想、认识进行反思,这都是
坚持一切从实际出发,实事求是的体现,这并不是唯心主义
的表现,故这一表述不妥。
4.有人说哲学研究人生问题,有人说哲学研究认识问题,其实
哲学只研究思维与存在的关系。

The next day I ran upstairs with a bag of groceries.Mrs.Riley was still in bed.I emptied the bag, put the milk in the tiny refrigerator,and then began dusting around.Sam hopped on his swing as I dusted the top of his cage.Paragraph2:After one week,she said,“I’ve been thinking,girl,since I can’t pay you,I’ll-I’ll give you Sam.”My breath caught in my throat.I couldn’t believe it.Sam.All mine.Sam looked at me.He chirped,as if to say,“Well?”I considered it.Someday I'd have enough money to buy a canary of my own.But Mrs.Riley would never get another one.Plus,if I took Sam,Mrs.Riley would be all alone.Could I take him?Sam waited.Mrs.Riley waited.“I can’t take Sam,”I said.“He belongs to you.And I’ll keep working for you.You don’t have to pay me.”This time Mrs.Riley heard me, without my shouting.音频材料Text1M:Megan,are we meeting Mrs.Brown at your office this afternoon?W:No,we have to pick her up at the hotel.①And then we'll go to a restaurant for dinnerText2W:George didn't attend yesterday's meeting?M:Yes.His mother was unwell.He sent her to the hospital and stayed with her.②W:Sorry to hear that.I thought he missed it because of the heavy traffic.Text3M:I'm particularly addicted to places with beachesW:Me,too.I enjoy lying on the beach.Well,would you like to try my new dish this evening?③M:Great.And then we can go for a walk in the park near your house.Text4M:Well,it was my fault because I didn't study as much as I should haveW:Why don't you choose American Literature again next term?④M:That's what I have decided to do.Maybe you can help me with my study in the library.Text5M:Hey,Aimee.I heard you made a new friend.Where is the girl from?⑤W:She comes from Houston.She used to be shy,but now she is gradually getting active in groupwork and more willing to express herself.Text6W:Hello.Dick.Where are you going?M:⑥I'm going to the stadium.W:⑥What are you going there for?M:⑥I'm going to take part in the tennis match there.Would you like to go with meW:Yes.Id like to.I'll go there to cheer on your team.M:Good.Do you like to play tennis?W:Yes,I do.But I don't play it very wellM:You need more practice.W:Yes,you're right.M:⑦Oh,it's fifteen past three now,Let's hurry.The match will start at4:00p.m.Text7M:⑧⑨I like this coat which is really warm.How much does it cost?W:It's not as expensive as you would think,It only costs$25.M:⑨That's relatively cheap especially since it is of very high quality.W:You should buy it soon.M:⑧Oh,I will.But it is a little small for me.Can you show me a bigger one?W:⑧Of course.Just a second.Text8M:⑩Did you attend the lecture on history given by Prof.Garcia yesterday?W:⑩No,I visited my grandfather.The doctor asked him to stay in the hospital for observation for a week.M:I wish he would fully recover soon.W:Thanks.I heard some students claimed they didn't understand some difficult points in the lecture.How did you find it?M:⑪Well,the lecture was not that hard.It was so attractive that I didn’t hear the bell ring.W:Could I borrow your notes?M:⑫Oh,don’t you know Prof,Garcia has put the video of his lecture on the website?

The second factor is more interesting.Some years ago an experiment dealing with the recording of eye-movements during sleep showed that the average human's sleep cycle is with eye-movements,some slow,others rapid.⑲People woken during the periods of eye-movements generally reported that they had been dreaming.When woken at other times they reported no dreams.⑳If one group of people were disturbed from their eye-movement sleep for several nights on end,and another group were disturbed for an equal period of time but when they were no eye-movements,the first group began to show some abnormal behaviors while the others seemed unaffected.All this suggests that it was not the disturbance of sleep that mattered,but the disturbance of dreaming.。

Even a basic term- a personal pronoun (代词)-can rise to the top of our data." The word secured the top spot when Merriam-Webster's annual traffic report showed searches for the term increased by 313 percent. And while the reason for the increase was likely affected by many things, Merriam-Webster believes the power of the pronoun cannot be overstated.English famously lacks a gender-neutral pronoun to correspond neatly pronouns like everyone'or someone'.As a consequence, they' has been used for this purpose for over 600 years. However, they' has also been used to refer to one person whose gender identity is non-binary, tha t is, neither male nor female, -WebMer r iamexplained.The publisher also pointed out major events in culture that arouse interest in the word, such as Sam Smith 's switch to use the pronouns a ndt heyhe m as well as the American Psychological Association 's recommendation that “they be used when referring to someone whose gender is unknown, or who prefers "they " over " he or she In September, Merriam-Webster added gender-neutral pronouns they" and a themselvesto the dictionary.Many were thrilled by the news, and non- binary people expressed thanks. They felt “ accepted " and " seen "Emily Brewster, a senior editor at Merriam-Webster, was also excited. Pronouns are among the language'smost commonly used words, and they tend to be mostly ignored by dictionary users, " Brewster said in a statement to NBC. But over the past year or so, as people have increasingly come across the non-binary use, we ' ve seen searches for 'they ' grow rapidly. ”( )24. What does the Merriam-Webster publisher think of the pronoun "they " ?A. It is quite powerful.B. It is almost worthless.C. It has been overused.D. It has nothing to do with culture. ( )25. What do the underlined words “ thireparrposepara graph 3?A. Discouraging people from using “someone".everyone ”.B. Matching other pronouns such asC. Mentioning someone whose gender is unknown.D. Replacing personal pronouns like “ . he” or “ she”() 26. Which of the following may Emily Brewster agree with?A.Pronouns are the most commonly used words by senior editors.B. Dictionary users tend to completely ignore pronouns in real life.C. The non-binary use contributes to the popularity of the word “ they ”.D. More searches for the word “ they c”an be seen in the past few years.CIf one more person talks about the benefits of mindfulness, I will throw cabbage at them. Just kidding. But I do have lots of cabbage happily rotting away in my,kitchen thanks to the wellness obsession (着迷)that failed to keepmy attention. This is a symptom of a phenomenon known as “ we.llness tiredness ”Wellness is seriously big business with a worth of $3.72 trillion and a healthy annual growth of 14 percent. To satisfy this consuming desire, brands of super foods and various exercise classes crowd in. The prob“lem with all this constantly changing information on what to eat or which exercise class to take is that people begin to form distorted (扭曲的)mindsets towards the idea of a healthy lifestyle, “explains DrBijal, a psychologist at Nightingale Hospit al. The“ least harmful result of a distorted mindset will be confusion. The most harmful would be serious physical and mental disorders like extreme dieting or over-exercising. ”It’s little wonder that many people are beginning to reject the idea of wellness a nd the lifestyle it advocates. I can’ t tell you the number of wellness accounts I ’ ve unfollowed on Instagram, itne” ss-oennethfusiast friend tells me. When I ask her why, she tells me that the public pursuit (追求)of wellness has reached “-rothlle eyestage .”Meanwhile, sales of fitness trackers and wearable wellness things have dropped sharply.Speaking of gym culture, which offers classes like Hula Hoop and Yoga, it ’s also beginning to show signs that people are returning to more conventional forms of exercise-some that wouldn ’t look out of place on a school timetable.The whole point of wellness is that it should become such an everyday thing that you forget about seeking it. Living a healthy lifestyle becomes a given rather than something singled out as impressive and worth applauding. Now, more people are starting to cycle to and from work, swim on lunch breaks and even try to buy old school exercise bikes.() 27. What is the main idea of paragraph 2?A.

一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,19分)阅读下面的文字,完成1~5题。
宇宙何处觅知音①1977年,“旅行者”探测器的升空,标志着人类第一次探索太阳系外的字宙文明的开始。
在著名天文学家卡尔·萨根主持下,“旅行者”搭载了两张镀金唱片,里头储存了地球想传递给宇宙的星际信息:118张描绘地球文明的照片、近90分钟世界各地的音乐、一部关于进化历史的音频。
这两张特殊的“星际唱片”承载了人类探索外星文明、进行星际交流的渴望。
②对有过“郑和下西洋”历史的中国人来说,这种走出闭关锁国、探索世界的想法,也许并不陌生。
但令国人更好奇的,或许是这张“星际唱片”里头的“中国元素”。
在照片部分,两种“中国形象”受到关注,一是“中国人的晚宴”,一是“中国的长城”,凸显了中国的“日常”和“奇迹”。
最后,是重中之重的音乐部分。
“星际唱片”收录的古琴大师管平湖先生演奏的中国古琴曲《流水》,是唱片中单曲片段时长最长的音乐。
它与唱片中最后一首音乐——贝多芬《第13弦乐四重奏》的第五乐章“短歌”,代表了地球想让宇宙聆听的人类音乐。
古琴是中国五千年音乐历史的象征,而“高山流水觅知音”的典故,暗合了人类摆脱孤独、追求知己的期望。
更重要的是,一曲《流水》,如同“子在川上曰,逝者如斯夫”的感叹,“面对奔流的江河或者任何自然界的奇观,人们会由衷地敬畏许许多多人类无法了解的奥秘”。
③面对浩瀚无垠的未知宇宙,人类自然会心生“敬畏”,有时难免会萌生对星际探索的犹疑和抗拒。
实际上,正如贝多芬《第13弦乐四重奏》所传达出的悲伤与希望共存的复杂感受一样,人类对星际探索尤其是主动与外星文明的接触也莫衷一是。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。
材料一:《文人画之价值》一文开宗明义:“文人画,画中含有文人之性质、趣味,不在画中考究艺术上之工夫,必须于画外看出许多文人之感想。
”陈师曾认为文人画是表达作者性灵与思想的载体,画面中含文人之性情、感想与追求。
画家作画不必刻意专注于艺术表现中形而下的技巧,也不必过分拘泥于物象原貌。
否则,他的个体风格与情感就会受抑制。
清代石涛有云:“借笔墨以写天地万物而陶泳乎我也。
”文人画的可贵之处源于何处?就在于它经过了作者性情的陶冶与思想的倾注,因而不会千人一面,毫无生气。
与此相伴,它也能让观者感同身受,涤除玄览,澄怀味象,这便是文人画的精义所在。
在中国传统绘画几千年的历史长河中,文人画成为区别于宫廷绘画、民间绘画和宗教绘画的四大画种之一。
复兴文人画,应具备人品、学问、才情、思想四要素,方能完善。
关于绘画与人品的关系,早在北宋,郭若虚曾有言:“窃观自古奇迹,多是轩冕才贤依仁游艺,高雅之情一寄于画。
人品既已高矣,气韵不得不高;气韵既已高矣,生动不得不至。
”郭氏论画,首次在画史上把人品与气韵甚至画作的质量联系起来,虽稍有绝对,但强调人品对绘画的重要影响,亦有其合理成分。
20世纪,陈师曾提出:“文人画之要素,第一人品,第二学问,第三才情,第四思想。
盖艺术之为物,以人感人,以精神相应者也。
有此感想、精神,然后能感人而能自感也。
”此论为未来中国文人画的发展指明了方向。
随后,傅抱石在分析和比较了董其昌、沈宗骞、陈师曾三人关于中国绘画思想的研究后,针对董其昌的“读书、广见闻、脱俗”之说,沈宗骞的“清心、读书、却誉、正体”之论,极力赞成陈师曾的观点,提出:“人品”“学问”“天才”,此为研究中国绘画的三大要素。
