Dear Jackson,
How’s everything going? Thank you for inviting me but I’m awfully sorry that I failed to go to enjoy the “hot”
Christmas with your family. I had been ill for several days when I received your invitation. Now I’ve learned with
delight that you’ve gained the important opportunity to participate in the Chinese Bridge Competition in Tongren .
How wonderful it is! I sincerely invite you to my family to spend the great festival, which is sure to leave a deep
and unforgettable impression on you.
Looking forward to your early reply so that I can make some detailed arrangements for your coming.
Wish you all the best!
Yours,

W:So,how is your German class going,John?
M:Well,not bad.The pronunciation is fine with me,and its vocabulary is similar to English.But I’m finding the
grammar awful.
W:Well,it takes a while to get it right.
Text 2
W:I hope you can come to the party on Saturday.
M:I didn’t know I was invited.
W:Sure you are.Everyone in our office is invited.
Text 3
W:May I help you?
M:Yes.When is the next train to London?
W:Oh,let me check.It leaves in twenty minutes.
M:One ticket,please.
Text 4
W:Charlie,do you know a restaurant called Bravo?
M:Bravo…I know the name.But I’m not sure where it is.
W:It’s on George Street.The food there is excellent.
Text 5
W:Brian,I just had an interview.They said they would make a decision soon.
M:What are your chances of getting the job?
W:Quite good.I think the interview went very well.
Text 6
M:Let’s go kite flying,Judy.It’s such a lovely day.
W:Okay,butlet me finish my chemistry homework first.Would you mind waiting for half an hour, Max? There
are a few sports magazines on the table.
M:Isn’t the chemistry homework due next Wednesday?
W:Yeah,but I have a full day of classes on Monday and a birthday party to attend on Tuesday. M:All right,
then.You go ahead,and I’ll catch up on some sports news while waiting.
Text 7
W:We’ve been on the computer all the time lately.Why don’t we do something different Sunday afternoon?
M:Well,we could go to a concert.
W:But I don’t think we can get the tickets this late.
M:Then what about playing a computer game? There’s a really cool new one we could download.高 三 英 语 3
W:Hmm,I don’t know.I feel like I need to do some exercise.We could probably just walk by the lake,and I’ll ask
Mike to join us.
M:That sounds like fun.Let’s doit!
Text 8
W:Welcome to our program,Dr.Peterson.Let’s see what questions we’ve got for you today.Here’s one:Can cats see
color?
M:Sort of.In the wild,many cats hunt at night because their eyes are designed for low light.Your cat can’t see bright
colors such as red and green.But it picks up more shades of blue,yellow, and grey than humansdo.
W:And why do cats give dead birds to their owners?
M:When your cat drops a dead bird at your feet,she isn’t bringing you a present.Most cats just drag food home
because it’s a safe place to eat.A cat’s mom also brings home things to her children to help them practice
hunting.So,a female cat without children may bring these“treats”to her owner instead.You may not like them,
but at least you don’t have to write her a thank-you note.
Text 9
W:How is little Ed doing at the kindergarten,Jack?
M:Oh,he’s doing fairly well.It’s been three weeks since he first started going,so Macy and I are pretty used to it
now.You should have seen Macy cry when Ed was about to set off on the first day,though.
W:I think that’s a normal reaction for mothers.You live quite close to the kindergarten,don’t you?
How does he get there?
M:Macy walks there with him every morning unless the weather is bad.When it rains,they’ll drive.
W:And is Ed enjoying kindergarten?
M:Yeah,he loves to have other kids to play with.He keeps telling us things they do together. W:What do the
teachers at the kindergarten say about him?
M:They said he’s bright,and that he’s starting to learn how to tell time.Isn’t that fantastic? W:That is fantastic.
It sounds like everything goes well.

My name is Emily.I had been a dancer for quite a long time.I started studying ballet when I was six years
old.By the time I was nine,I was dancing five days a week.When I was eighteen, I decided that I really
preferred contemporary dance and that I wanted to do it professionally.So I applied successfully for the training
program at the School of Toronto Dance Theatre,and moved to Toronto to attend the program.That was the
period of time I enjoyed most in Toronto.I graduated on scholarship and danced professionally for ten years.But
after all those years,I found that dance was gradually becoming something that felt like more of a burden than a
joy.I found myself increasingly unwilling to drag myself to dance performances,so I quit.I do miss dance,often.
But it makes me happy to think that I’ll never have to go to another training session again.高 三 英 语 4
阅读理解答案详解
A
21. B [细节理解题。根据文章"Long Weekend City Escape" 这一部分中"Book before Thanksgiving and
they'll throw in an extra night for free, too." 可知,感恩节之前预定会免费多住一晚,故选 B。]
22. D [细节理解题。根据文章"Holiday Dinner in Paradise" 这一部分中"It isn't just about holiday meals, of
course. Your gift also comes with soft sand beaches, pools with water slides and lazy rivers, cultural activities,
and free kids' clubs, too." 可知,这里不只是假日大餐,还有柔软的沙滩、游泳池,文化活动、免费儿
童俱乐部,故选 D。]
23. A [推理判断题。根据文章标题"Disney Lover's Gift Guide" 可知,本文主要是迪士尼爱好者礼品指南,
根据文章各个部分内容可知,本文介绍了"Meet Mickey and Minnie"、"Long Weekend City Escape"、
"Holiday Dinner in Paradise" 部分以及"Safari Style" 四种可以作为礼物的活动,由此可以推断,本文是
写给要送礼物的人,给他们家推荐了一些活动,可以作为礼物,故选 A]。
B
【语篇解读】 本文讲述了作者两次停止购物的经历,告诉大家不要浪费时间金钱去买不需要的东西。
24.C [细节理解题。根据题干关键词“stopped shopping again”定位到文章第二段。根据段中句子“I noticed I
had replaced this addiction with another-buying useless things on the internet. ”说明作者发现自己虽然摆脱
了商场购物,但却又沉迷于网上购物,所以果断再次停止购物,因此正确答案选 C。]
[错项分析] 同学们容易忽略题干中的 again,从而无法准确定位到第二段,只能根据印象选择了 A 或
D,A 中的 comparing goods 和 D 项中的 looking in stores 表述和原文不一致。
25.D [细节推断题。定位到第三段,句子“It was exciting to realize that there is nothing wrong with liking
beautiful things. In fact, it’s hard not to like beautiful things in a world that’s filled with them, in a world
that’s good at showing you the kind of beautiful thing you most want, and in a world where people try to
make you want beautiful things. ” 意指商家利用人的爱美之心让你去消费本不需要的东西,故正确答案
选 D.“Producers are taking advantage of her desire for beautiful things. ”]
[错项分析] 易错选 A 项。 A 项表达不准确,应当是 It’s natural to love beautiful things。
26.B [细节判断题。定位到最后一段,句子 It also works to take some time to stop and think about why you
want that shiny new thing. (花些时间停下来想想为什么要买那个亮闪闪的新东西,也能起作用。)对应 B
项 reflect on what causes our desire to buy something(思考下为什么要买某个东西)。]
[错项分析] A 项没有提到;C 项 talk about 错,应为 think about; D 项 harmful effects on the environment
没有提到。
27.A [主旨大意题,考查文章意图。本文前两段是过渡段,先讲述自己两次停止购物的经历,然后分析人
们为什么沉迷于购物,以及购物给消费者自己以及环境等带来的伤害,最后作者分享了自己避免沉迷
购物而采取的方法,画画。因此整篇文章是分析她对沉迷购物的体验和理解。]
[错项分析] C 项错在只提到 on line shopping;B 项并不是作者全部意图;D 项意义有悖于原文。高 三 英 语 5
C
【语篇解读】 本文属于议论文,讲述了“成年人需要不断的学习,奉献,这样的生活才会有意义”。
28.C [词义猜测题。根据第一段 I’m talking about people who have stopped learning on growing because they
have adopted the fixed attitudes and opinions that all too often come with passing years. 故可知,作者谈论
的不是那些没有到达巅峰的人,而是谈论那些不再学习成长的人,故可知 run out of steam 意思为停止
学习。]
[错项分析] 多数同学只知道 steam 的意义是“蒸汽”,这是题目难点所在。应该根据上下文来判断陌生
单词和词组的意义,不能望文生义,此处 steam 表示“精力,热情”。
29.B [推理判断题。根据第二段 we lose our sense of wonder. But, if we are willing to learn, the opportunities
are everywhere. 可知,我们失去了好奇心,但是如果我们愿意学习,机会无处不在,故可知,机会总
是留给那些好奇心的人。]
[错项分析] 其他选项句子本身也有道理,容易误选,这些选项都跟段落主题关联不大。A.Those who
dare to try often get themselves trapped. (敢于尝试的人常会囿于其中);C.Opportunity awaits those with a
cautious mind. (机会留给那些小心谨慎的人)D.Those who tend to think back can hardly go ahead. (善于
反思的人会止步不前);。
30.D [推理判断题。根据第三段 we learn to bear with the things we can’t change. We learn to avoid self-pity.
We learn that however much we try to please, some people are never going to love us—an idea that troubles
at first but is eventually relaxing. 可知,我们学会承受那些无法改变的事情,学会避免自怜,也学会了
无论我们怎么去取悦别人,有些人是无法喜欢我们的,这个观点起初让我们苦恼,但是之后会让我们
释怀。故可知,本段作者告诉我们要学会使用恰当的方式来对待生活。]
[错项分析] A、B 项段中没有提及;C 项与段中“无论怎样取悦别人,总会有人不喜欢我们”相左。
31.A [主旨大意题。本文讲述成年人需要不断的学习,奉献,这样的生活才会有意义,故本文作者的目的
是为了指导我们过一个有意义的成年人生活。]
[错项分析] B 项错在 shouldering responsibilities(承担责任);C 项错在 generating motivation(增强动机);
D 项错在 a way of pursuing excellence(追求卓越的方式),上述内容都在本文没有提到,或者不是重点
内容。
D
【语篇解读】 这是一篇科普类阅读。文章主要介绍了人类的嗅觉基因和嗅觉系统,科学家们通过研究嗅
基因和嗅觉系统是如何工作的,发现了嗅觉对我们生活的影响。
32.C [细节理解题。根据题干信息 Richard Axel and Linda Buck find out 定位在第三段,段中句子 These two
scientists were the first to describe the family of 1,000 olfactory ( 嗅 觉 ) genes and to explain how our
olfactory system works. (这两位科学家首次描述了 1 000 个嗅觉基因家族,并解释了我们的嗅觉系统是
如何工作的。)由此可知 Richard Axel 和 Linda Buck 这两位科学家发现了人类嗅觉系统的本质。]
[错项分析] 本题定位时需要找到两个名字,并且注意到文中 noted that 和 find out 是近义表达。只要
定位准确,选项本身并没有太大干扰。
33.D [细节理解题。根据题干关键信息 help people concentrate 定位在第五段。段中 Similarly, the smells of高 三 英 语 6
lemon and coffee appeared to promote clear thinking and mental focus. 可知喝咖啡有助于提高思考和注
意力。]
[错项分析] 本题难点也是定位。题干 help people concentrate 和第五段中 improve concentration levels
意义相近,为定位标准,定位准确,答案就显而易见。
34.A [推理判断题。根据题干定位在最后一段。段中句子 The Israel researchers say their study shows that
nearly every human being shows a different pattern of active and inactive smell-detecting receptors. (以色列
研究人员表示,他们的研究表明,几乎每个人的嗅觉感受器的活跃和不活跃模式都不一样。)由此可知
不同的人对不同的气味敏感。]
[错项分析] 易错选 B 项和 C 项。根据 a different pattern of active and inactive smell-detecting receptors.
说明 B 项的 genes 错误;根据 identified at least 50 olfactory genes which are switched on in some people(确
定至少 50 组嗅觉基因组在一些人身上激活),不能推断这些人能辨别 50 种以上的味道,说明 C 项错
误。
35.B [主旨大意题。首段点题类文章,根据首段就可以判断主题大意。第一段 Recent studies have found,
among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads. (最
近的研究发现,比萨等食物的味道会让道路上的司机产生无法控制的愤怒)是全文的主题句,结合全文
内容,可知这篇文章主要介绍了气味及其影响。]
[错项分析] 易错选 D 项,因为文中多次提到 olfactory genes。但是 olfactory genes 只是用来分析嗅觉
的原理,也是用来证明嗅觉如何给我们带来影响的,所以 D 项只是其中部分内容,不是全文的主题内容。
七选五
【语篇解读】 这是一篇说明文。文章介绍了白手起家的百万富翁告诉他们的孩子关于财富的几点事情。
36.C [段中句。根据上文 Likely,you do not have an answer because you would not call yourself rich. 你不是
富人,不知道答案。接下来本题的意思应该是“那就让富人来说说怎么在钱的问题上教育小孩的”,然
后语意上对应下句 “下面就是百万富翁跟孩子讲的财富的事情”。]
[错项分析] 受相近词汇的影响,同学会错选 B 和 E。B 项内容跟后句语意不搭配。E 项只是 rich 出
现在上句中,语意上也不搭配。
37.A [段尾句。根据上文 Self-made millionaires teach their children that they deserve to be rich not because
they were born into the right family but because they work hard to solve other people’s problems. 可知,富
人教育孩子他们值得拥有财富是因为他们努力解决他人的问题,而不是出生在富有家庭,故可推测下
文:所以拥有财富可以帮助他人为你挣得一席之地。]
[错项分析] 本题关键是语意,需要跟段落标题 You deserve to have wealth 相符,又要和上句内容相符。
38.G [考查标题句。根据其他段落标题特点,本题应该是简短的陈述句,表示一个论断。据此排除两个问
句 C、D;排除长句 A、B,排除开头有“转折、递进”等词的 E、F,所以答案为 G。从语意上来讲,
根据下文 Having money gets rid of tons of the issues which people find themselves in when they do not
have it. (有了钱,人们就可以摆脱很多问题,这些问题是人们在没有钱的时候发现自己陷入的。)可知
这一段讲财富给人自由,有了钱你能做自己想做的事,敢不做自己不愿做的事。]
[错项分析] 本题要学会根据小标题的句子特点缩小选择范围,或者使用排除法最终确定答案,是一高 三 英 语 7
种高效的做题方式。
39.B [段首句。首先要与标题句 Nothing is guaranteed. 语意相通。 再根据后文 They must create their own
lives and futures. 可知他们必须创造自己的生活和未来。由此推测本题是指:世界不欠谁的,一切皆由
自己挣得。这符合小标题内容,也与后面的内容协调。]
[错项分析] 本题的关键是语意理解,既要关联主题句,又要关联段落内容。
40.E [段中句。首先要符合小标题语意,即解决问题赚取财富。再根据上句 The bigger the problem the more
difficulty you might have getting it off the ground. (问题越大,你可能就越难以将其付诸实施。)这跟后面
句子“提高解决问题的能力是通向财富之路”语意相左,所以本题应该是这两层意义转折的句子,因此
锁定答案 E. But it could also make you rich. (……但是这也会让你变富)。]
[错项分析] 本题需要体会句子之间的逻辑关系,寻找提示关联意义的词汇,从而容易确定答案。
完形填空答案详解
【语篇解读】 这是一篇夹叙夹议的文章。文章作者通过自己成长过程中的亲身经历,教育自己的女儿,
在开始尊重其他人之前,她首先要找到自尊。
41.D [考查形容词辨析。根据 When I was young, my understanding of life was simple. 可知,这让我更容易
与周围的世界打交道。D.easier 更容易的。]
[错项分析] 本题的选择需要照应上句“我认为生活很简单”,其他选项无法对应 simple。A.funnier
更滑稽的;C.safer 更安全的;B.deeper 更深。
42.B [考查形容词辨析。根据 which made life more challenging. 可知,随着我的长大,事情似乎变得更加
复杂。B.complex 复杂的。]
[错项分析] 需要对应后面的 challenging,也要和上句的 simple 和 easy 形成对照。其他选项的意义无
法表达此意。A.important 重要的;D.awkward 尴尬的;C.fragile 易碎的。
43.A [考查名词辨析。句意:现在,中年了,我发现我的世界观正在回归简单。A.view 观点。]
[错项分析] 本题容易忽略前文的对应词汇而错选 D 项。第一句中 my understanding of life was simple,
结合本句 returning to the simple,很显然是对应 understanding 的词汇,即 view“观点、看法、理解”。
其他选项无法照应上文,也缺乏语境。B.experience 经历;C.aim 目的;D.expectation 期待。
44.A [考查名词辨析。下句中 one of those basics 是关键信息,表示我教女儿的东西,所以这里应该是 basics
基础知识。 ]
[错项分析] 本题 A 项意义广泛,可以包含其他三项。B.facts 事实;C.subjects 科目;D.choices
选择。
45.C [考查固定短语。句意:当我试图教我女儿重要的生活基础知识时,我会把复杂的东西分解成小块知
识。break down into 分解成,该短语是固定短语。]
[错项分析] 其他选项无法搭配 break 表示“分解、拆解”的意思。
46.C [考查名词辨析。本句点出了文章的主题,即 respect 尊重,这可以从全文描述的内容看出来,也可
以根据后边句子 because you can’t respect yourself for it. 判断出来。]
[错项分析] 其他选项都脱离了本文的主题。A.passion 激情;B.love 爱;D.desire 欲望。高 三 英 语 8
47.D [考查动词辨析。根据下句 To fail feels bad, __8__, but not to have tried feels worse(失败不好受,但
是不去尝试就更加难受)可知,我教我的女儿去尝试。 try 尝试。]
[错项分析] 其他选项没有合适语境。A.forgive 原谅;B.accept 接受;C.share 分享。
48.A [考查副词辨析。句意:当然,失败让人感觉很糟糕,但没有尝试让人感觉更糟,因为你无法为此尊
重自己。A.certainly(当然)在此修饰前半句,而不是修饰 but 后边句子。]
[错项分析] 本句容易出错,主要原因是没有弄清楚要填的词应该修饰前句,但在结构上被后置了。
其他选项语意不对。B.eventually 最后;C.personally 亲自地;D.willingly 很乐意,情愿。
49.B [考查固定句型搭配。句意:俗话说,如果你不尊重自己,没有人会尊重你。as the saying goes(俗话
说),该短语是固定短语。]
[错项分析] 其他选项无此搭配。
50.B [考查固定短语辨析。句意:有一个是我一直特别想要的,我让它滑进了口袋。此处短语 in particular
放在句中语意正确。]
[错项分析] 本句的关键在于准确理解挖空处的意义以及修饰关系。其他选项语意不搭配。A.for fun
开玩笑地;C.with care 小心地;D.at random 随便地。
51.C [考查动词辨析。句意:有一个是我一直特别想要的,我偷偷放进了口袋。用 slipped 和后面 into my
pocket 搭配,表示“偷偷装入我的口袋”,符合语境。]
[错项分析] 其他单词搭配 into 语意不对。A.fetched 取来;B.arranged 安排;C.slipped 使滑入;D.fitted
适用。
52.D [考查动词辨析。句意:但过了一会儿,我感觉到,即使在那个年纪,我也永远不会喜欢玩这个玩具。
表示“感觉到,意识到”,照应后文自己归还玩具的场景。]
[错项分析] 很多同学只把 sense 当名词用,其实也常用作动词,类似于 realize。其他选项无法表达当
时作者的心理。A.doubted 疑惑;B.promised 许诺;C.questioned 怀疑。
53.B [考查动词辨析。句意:我将永远知道我偷了东西,我对自己的看法也会受损害。根据上文“把东西
装入自己口袋”,是在偷东西。]
[错项分析] 这里明显是偷窃行为,不能理解为撒谎或者欺骗。A.lied 撒谎;B.stolen 偷窃;C.changed
改变;D.cheated 欺骗。
54.A [考查动词辨析。句意:我将永远知道我偷了东西,我对自己的看法也会受损害,这里是指“无法尊
重自己”。 suffer 受损害。]
[错项分析] 易错选 C 项,opinion 和 fade 搭配不对。其他选项也无法表达合适语意。B.improve 改
善;C.fade 褪色;D.spread 传播。
55.C [考查动词辨析。根据 and gave it back 可知,这里意思是我羞愧地把玩具掏了出来。pull 本意是“拖、
拉”,此处表示“从口袋里慢慢掏出来”,和前面的 slipped 用法正好相呼应。]
[错项分析] 其他选项无法描述自己从口袋里慢慢掏出文具的动作。A.gave 给;B.left 离开;D.handed
递送。
56.D [考查连词辨析。句意:我敢肯定,她知道发生了什么事,但她感谢我,而且再也没有提起这件事。]
[错项分析] 要读出挖空前后两个句子之间的转折关系才能确定答案。
57.B [考查名词辨析。句意:我希望能帮助我的女儿避免类似的错误。我前面的偷玩具的做法肯定是“错高 三 英 语 9
误的行为”。]
[错项分析] 结合上文容易做出正确判断。A.accidents 事故;B.mistakes 错误;C.results 结果;D.habits
习惯。
58.A [考查连词辨析。句意:在她开始尊重其他人之前,她首先要获得自尊。本句是一种议论,起到点题
的作用。 before 在……以前,在本句可以翻译为“然后才……”。]
[错项分析] 其他选项语意不对,翻译不通。B.until 到……为止;C.in case 万一;D.now that 既
然。
59.C [考查介词辨析。句意:我相信尊重,因为没有尊重,我们都是敌人。]
[错项分析] 易错选 beyond, beyond 表示“超越,在……之外”,本句需要表达“如果没有”,despite 语
意也不对,而且也不能直接跟代词 it。
60.D [考查形容词辨析。根据 far from it(差得远)可知,这里意思是“在这方面我并不完美”。D.perfect 完
美的。]
[错项分析] 易错选 honest,作者最后归还了玩具,虽有错误,但也及时改正,这是“不完美”,不是“不
诚实”。A.honest 诚实的;B.casual 随便的;C.curious 好奇的。
语法填空答案详解

几年前由重庆交通大学的研究人员开发的。在接下来的几年里,科学家们相信他们可以把 3 万英亩土
地变成肥沃的土地。
61.was developed [考查被动语态。句意:这项技术是几年前由重庆交通大学的研究人员开发的。句子
主语 The technology 和 develop 之间是被动关系,再根据 several years ago 可知句子用一般过去时态的
被动语态,故答案为 was developed。]
62.made [考查过去分词作后置定语。句意:他们发明了一种由植物细胞壁中发现的一种材料制成的糊
状物,这种材料与沙子混合后可以保持水分、营养和空气。此处 a paste 和 make 之间是一种被动关系,
这里是过去分词作后置定语,故答案为 made。]
63.with [考查固定词组。句意:他们发明了一种由植物细胞壁中发现的一种材料制成的糊状物,这种材
料与沙子混合后可以保持水分、营养和空气。mix...with...把……和……混合在一起,故答案为 with。]
64.extremely [考查副词。句意:据 CGTN 报道,中国科学家已经成功地在缺少雨水和极端高温的恶劣
条件下种植农作物。此处 hot 是形容词,副词修饰形容词,故答案为 extremely。]
65.themselves [考查反身代词。句意:许多不是人类种植的,而是自己生长的。结合句意可知此处用反
身代词,故答案为 themselves。]

漠。结合句意可知答案为 a。]
70.confident [考查形容词。句意:在接下来的几年里,科学家们相信他们可以把 3 万英亩土地变成肥沃
的土地。be 动词后面用形容词作表语,故答案为 confident。]
