We’re giving people high-quality, healthful products and an opportunity to make choices that have a __63__ effect on the world. It’s not just the building industry, either.

In reality it has more to do with the way an individual talks to himself. Self-talk is a constant stream of thoughts of a person, who is often unaware and uncertain of some events, phenomena, people, or even the person himself.____1____Meanwhile, positive thinking can help to stop negative self-talks and start to form a positive view on an issue. People who regularly practise positive thinking tend to solve problems more effectively. They areless exposed to stress caused by external factors. They tend to believe in themselves and in what they do.____2____People who think positively demonstrate increased life spans, lower rates of depression and anxiety, better physical and psychological health, reduced risks of death from heart problems. Positive thinking also contributes to one’s ability to deal with problems and hardships.____3____For example, researchers have found that in the case of a crisis accompanied by strong emotions, such as a natural disaster, positive thinking can provide a sort of buffer against depression and anxiety. Resilient people who think positively tend to treat every problem as a challenge, a chance for improvement of any kind, or as an opportunity for personal growth. Pessimists, on the contrary, tend to perceive problems as a source of additional stress.____4____ In conclusion, positive thinking is a powerful and effective tool for dealing with hard times and improving the quality of one’s life. It doesn’t have anything to do with ignorant optimism when an individual refuses to notice a problem.____5____ Thinking in a positive, self-encouraging way brings about many benefits to one’s physical and mental health.A. It doesn’t cause any severe emotional discomfort, either.B. Negative self-talk damages self-confidence and decreases self-respect.C. It helps one to remain clear-headed and confident in difficult situations.D. Positive thinking has several beneficial effects on the body and the mind.E. As thinking changes, an individual’s behaviour and habits change as well.F. They often offer a real alternative to the common and regular way of thinking.G. They often feel discouraged long before trying to solve the problem, even if small.三. 完形填空Normal people can hardly imagine what kind of pain orphans feel while growing up – being abandoned, disliked, and laughed at.

Will Hunting, the main character in the US film Good Will Hunting is the perfect example.The story is simple.

2017届高考英语二轮复习大题冲关秘籍语法填空:解题技巧(含解析)

第一部分有提示词题目的解题技巧有提示词题目是指"使用括号中词语的准确形式填空"这类题,近年来的高考题只考查谓语动词的时态和被动语态、非谓语动词、形容词和副词的比较级、词类转化等四种情况。
【考点】【解题技巧】当句子缺少谓语动词时,括号中的动词就是谓语动词。
此时,要根据语境确定用哪种时态,根据主语与该动词的主动或被动关系确定用主动语态还是用被动语态。
具体解题技巧如下:第一步:确定句中是否缺谓语或并列谓语,如缺谓语动词,则填谓语动词。
第二步:若为谓语动词,就要看主语与谓语之间是主动关系还是被动关系,以确定用主动语态还是被动语态,同时还要根据语境考虑用哪种时态。
第三步:要注意主谓一致。
【典型例析】1.He ______(pretend) that a tiger toy was real and giving it a voice.【解析】在主语He后,pretend显然是谓语动词;giving it(the tiger)a voice的主语理应是He, 所以,and giving与谓语动词是并列关系;由此推断,谓语动词应是过去实行时,故填was pretending。
【答案】was pretending2.One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he ________ (find) that he had run out of salt.【解析】在主语he后,find显然为谓语动词;由前面句意可知,此处为一般过去时,故填found。
【答案】found3. I was on my way to the Taiyetos Mountains. The sun was setting when my car ________(break) down near a remote village.【解析】在when后的分句中,my car是主语,其后的break应为谓语动词;由全文可知,这是叙述过去的经历,用一般过去时;再说was / were doing... when...did...是一个固定句型,when后面的句子的谓语用一般过去时,表示"正在做某事,就在这个时候突然发生了另外一事",故填broke。
高考英语二轮复习英语练酷版练习:专题三_习题讲评_课五_word版含解析

因惯性思维而错选在英语教学中,由于种种原因,如学生的母语、知识面、思维习惯等都有可能令学生出现一些思维定式现象,即不善于思考,考虑问题不全面,导致误解一些题目,抑制思维能力的发展。
在做完形填空题时,特 别要注意中西文化的差异,克服思维定式。
要养成用英语思维的习惯,要随着文段发展脉络,调整思维偏差。
(一)学习单词时受到的思维定式影响有些考生学习英语单词过于简单化,仅记其中文意思,而不深刻理解其实际用法和英汉用法之间的细微差异。
[典例1] (2018·6月浙江高考)One day I 46.met a former classmate of mine who was47.making a lot of money running a sideline (副业).Since his regular job was48.boring, I asked him why he just didn ’t do his sideline full -time.He said without the job, he would 49 have too much time and would just do what I did back in 50.college. He said that if he51.quit the job, he would lose his52.drive to work and succeed.49.A.luckilyB .hardlyC .hopefullyD .simply分析:选D 根据语境可知,他说如果没有那份工作,他确实会有很多时间。
simply “(强调某说法)确实,简直”。
simply 这个词对于习惯汉语思维的我们而言有点儿抽象。
我们比较熟悉的是它表示“简朴地;简单地”的义项,如:The rooms are simply furnished.和The book explains grammar simply and clearly.(二)学习短语或习惯用语时受到的思维定式影响例如:学了wait for 这个短语以后,有的考生在做题过程中只要碰到wait ,后面要接介词时就毫不犹豫地选择for 。

【2022届福建省漳州市高三二模】When people hear “artificial intelligence (AI)”, many think of big data. There’s a reason for that: some of the most prominent AI breakthroughs in the past decade have relied on enormous data sets. But AI is not only about large data sets, and the research in small data approaches has grown extensively over the past ten years.
If you take the top 100 biggest innovations of our time, perhaps around 60% to 65% are really based on small data. Big data is all about finding connections, but small data is all about finding the causation, that is, the reason why.

They are the saguaro cacti (树形仙人掌), a giant which gives the landscape its __1__ appearance. In the dry desert the saguaro cacti can live for more than 200 years, grow to a __2__ of 60 feet, and have as many as 50 arms.More __3__ , the saguaro cacti still persist despite the unbearable desert climate. Those that have grown to old age have __4__ droughts, freezes, flash floods, and bush fires as well as the __5__ caused by groups of rats that eat their seedlings(秧苗). Like all other desert __6__ , these leafless giants can store water for use during the desert's long dry seasons by __7__ water through their long roots.Naturally, the great saguaro cacti are a(n) __8__ part of the desert life. Actually the giants may be __9__ to many animals, including woodpeckers, owls, doves, bats and insects. In addition, after a saguaro __10__ the age of 50 or so, cold-resistant flowers __11__ at the top of the plants once a year. These flowers __12__ birds, bats and bees, which come for the honey and for the tasty flowers with their black seeds.__13__ the splendid saguaros are plentiful in the Southwest, they are unfortunately __14__ . These giant cacti have great value in landscape gardening, and the thieves can earn thousands of dollars by uprooting and __15__ them to nurseries (苗圃). To protect these southwestern __16__ , agents for the Arizona Department of Agriculture go around and __17__ the desert. It's a most important job though a hard one. But without the saguaro cacti, many desert animals would suffer a lack of __18__ and loss of nesting sites. The Southwest, too, would __19__ something of unique importance, since these desert giants have becomea __20__ of the dry region.1. A. general B. basicC. uniqueD. lovely2.

文章从奇特的形状、生活特性、经济价值等方面介绍了Sonoran Desert(索诺兰沙漠)的标志性植物——树形仙人掌。
1.解析:根据下文可知,树形仙人掌有多达50个分枝,所以形状“独特”,故选unique“独特的”。
general“普通的”;basic“基本的”;lovely“可爱的”。
答案:C2.解析:根据前面的“giant”及后面的“60 feet”可知,此处表示的是“高度”,因此选height。
length“长度”;size“尺寸”;width“宽度”。
答案:B3.解析:根据上文可知,游客对树形仙人掌的形状会感到非常惊讶,故此处指更令人惊讶的是它们的适应能力,因此选amazingly。
pleasingly“令人愉快地”;inspiringly“鼓舞人心地”;interestingly“有趣地”。
答案:D4.解析:根据上下文可知,树形仙人掌“经历”了恶劣环境的考验,live through“经历”符合语境。
break through“突破”;cut through“抄近路穿过,走近路”;get through“接通电话,通过考试”。
答案:A5.解析:除了恶劣的气候外,树形仙人掌还要遭受老鼠的“破坏”,因此选damage。
crisis“危机”;destruction“毁灭”;load“负担”。
答案:B6.解析:此处指像沙漠里其他所有的“植物”一样,因此选plants。
life“生命”;animal“动物”;creature“生物”。
答案:A7.解析:树形仙人掌通过它们的长根茎吸收水。
absorb“吸收”,符合语境。
pour“倒,灌”;squeeze“挤压”;pump“抽出”。
答案:D8.解析:根据下文可知,作为许多动物赖以生存的食物和家园,树形仙人掌是沙漠“极为重要的”部分,因此选vital“极重要的”。
independent“独立的”;original“原始的”;mysterious“神秘的”。
答案:B9.解析:根据最后一段的倒数第二句“But without the saguaro cacti... loss of nesting sites”可知,树形仙人掌可能是许多动物的栖息地。
因此选home“栖息地”。
spot“地点”;field“田地”;camp“营地”。
答案:C10.解析:此处指在树形仙人掌长到50岁左右之后,故此处选turn意为“到(某年龄或某个时间)”,其后直接跟数字。
take“带走”;meet“遇到”;gain“获得”。
答案:A11.解析:根据上下文可知,这里指树形仙人掌在长到50岁左右以后每年开一次花,因此选come out“(花朵)开放”。
come up“走近,被提到”;show off“炫耀”;show up“露面,到达”。
答案:B12.解析:根据下文中的“which come for the honey”可知,树形仙人掌的花吸引了一些动物,因此此处选fascinate“迷住,深深吸引”。
