【題目】Why do some people eat too much? Is it because they’re hungry? Or is there a scientific 【1】(explain)?

There are a number of theories to account【2】overeating. One factor depends on the time of day. “It’s all part of a routine,” says Randy Seeley,【3】professor of psychiatry in Cincinnati. “You’re hungry at noon because that’s the time you 【4】(eat)lunch for the past 100 days.” Another reason we may eat more than necessary is that the body needs to satisfy a salt and sugar balance. Drinking alcohol also increases appetite, because the body wants something 【5】(absorb) the alcohol.

【6】(basic), overeating can also be a question of more biological factors. For instance, your body temperature can tell your brain that you feel hungry. “Your body temperature【7】(drop) when it’s time to eat, and eating warms you up,” says Gina Harlow, a paediatrics professor at Harvard University. Also, the smell of certain foods can make us imagine subconsciously the pleasure of eating【8】. Harlow adds, “If you know you love French fires, 【9】(smell)them will make you want to eat them because you know how good they are,【10】 can lead to eating too many.”

So, the next time you realize you’ve eaten too much, don’t worry about it. You can always blame it on science.

【答案】

【1】explanation

【2】for

【3】a

【4】have eaten/have been eating

【5】to absorb

【6】Basically

【7】drops

【8】them

【9】smelling

【10】which

【解析】 本文是關(guān)于飲食的科學(xué)常識。主要講述了有些人吃的太多的原因。

【1】explanation

考查名詞。句意：為什么有些人吃得太多？是因為他們餓了嗎？還是有科學(xué)的解釋？本句中explain被形容詞scientific 修飾，形容詞不能修飾動詞，故用名詞explanation。

【2】for

考查固定搭配。Account for…. 是……原因、理由 ，對……作出解釋說明，（在數(shù)量、比例上）占，句意：這里有許多理論可以解釋為什么吃得過多。故填for.

【3】a

考查冠詞表數(shù)量。一位精神病教授說，表示數(shù)量的，第一次提及的要用不定冠詞a。

【4】have eaten/have been eating

考查固定句式的時態(tài)。句意：你中午很餓，因為這是你在過去100天吃午飯的時間。根據(jù)It’s the time that從句要用現(xiàn)在完成 時，故要用have eaten/have been eating.

【5】to absorb

考查動詞不定式作狀語。句意：喝酒也能增加食欲，因為身體想要吸收酒精。分析句子可知，本空表示目的，故要用動詞不定式to absorb。

【6】Basically

考查副詞�；旧希╋嫳┦骋彩且粋�生物學(xué)因素的問題。分析本句可知basical是修飾一個句子“暴飲暴食也是一個生物學(xué)因素的問題”，故要用副詞basically.

【7】drops

考查謂語動詞。句意：當(dāng)你到了吃飯的時候，你的體溫會下降，吃東西會使你暖和起來。drop主語是temperature，第三人稱單數(shù)形式。故要用drops

【8】them

考查代詞。句意：而且，某些食物的氣味可以讓我們潛意識地想象吃它們的樂趣。本句的動詞eat 的賓語是the smell of certain foods。故要用them.

【9】smelling

考查動詞的ing形式在句中作主語。聞著會讓你想吃掉它們。Smell them 作will make you….，可知smell them不能作主語，要用動詞ing形式作主語，故用smelling。

【10】which

考查非限制性定語從句的引導(dǎo)詞。句意：因為你知道他們有多好吃，這會導(dǎo)致吃太多。根據(jù)句子you know how good they are,___can lead to eating too many.”可知which 是修飾句子you know how good they are，故要用which，故用which。

Good afternoon,

I am writing to request more information on your new Automated Alert Service,as advertised on your Website.I have had both personal and commercial accounts with Citizens' Bank for many years.Often,I find it necessary to move money between accounts.Because of this,it is vital that I keep a close eye on the cash flow of all of my accounts,to assure that their balances stay above the required minimums.Therefore,I have been searching for an economical means of keeping better track of my finances.I was considering purchasing software for this purpose,but I think that your new service might be a convenient alternative.

【題目】Fixed or growth mindset — which do you have?

We live in an uncertain world with all the technological advances we are experiencing， which meanse is a requirement for a change in midset (思維模式）. In order to be on top of our game both personally and organizationally, we need to develop a growth mindset.

A fixed mindset supposes that you have native abilities and are naturally clever or skilled in certain areas of life. When you receive infonnation about how you have performed in a test or set of tasks t you may worry about how you are judged. Our parents probably said to us when we were young,"Since you scored really well in the test, you must be clever." However, by being repeatedly told “You arc clever” or “You are really ga*al al your job”，a person’s self-respect is actually dainagcd.

The growlh - mindest persona view life as a series of exciting challenges and want t o constantly learn. Brain activity occurs in this mindset when they receive information about what they could do belter or improve. They do not view their abilities as fixed or us failure. Learning is king and the more they practice , the more they know they will succeed.

What is important is giving praise around process and not around ability. For example , instead of saying"Since you got a great score, you must be clever" f say " You got a great score, and you must have tried really hard". This creates challenge in indivicluats and

The meanin of mindsets is massive for business. Fixed-mindset managers are not fans of giving feedback (反饋）. They do not want to stretch themselves or others because they fear failure. Therefore their business may stand still because there is no risk or innovation (創(chuàng)新） occurring.

Listen from your own fixed mindset 一 for example ," I can't do that” 一 and answer with a growth-mindset response 一 “I can't do that yet!" Remember there is no such thing as failure and there is s only learning. If you don't fail occasionally ，you will never learn to change and grow.

【1】What is the author's opinion of people' s mindsets?

A. A growth mindstet means no failure.

B. People need develop a fixed mindset.

C. A fixed mindset focuses more on process.

D. People should develop a growth mindest.

【2】Which judgment seems more encouraging?

A. You are clever.

B. You are skillful.

C. You have worked hard.

D. You arc great at your job.

【3】What do the growth-mindset persons most advocate?

A. Keeping on learning.

B. Viewing ability as failure.

C. Giving praise around ability.

D. Learning from the fixed mindset.

【4】What is the main idea of the last paragraph?

A. Always stay in ihe same mindset

B. Think and act in different mindsets.

C. We can 't miss the chance of failure.

D. Learning is the key to success from failure.

【題目】The American state of Colorado is considering a ban on smartphones for children younger than 13.

A Denver-based doctor - and father - is leading the effort. Tim Farnum is the founder of a group called ‘Parents Against Underage Smartphones.' His proposal would ban sales of smartphones to children under the age of 13. It would also ban sales to anyone who wishes to buy such a device for anyone younger than 13. The measure would also require sellers of smartphones to provide proof to the state government that they have asked buyers if the phone is for anyone under 13.

The measure now needs about 300,000 signatures in order to appear on Colorado's statewide ballot (投票權(quán))next year. If it makes the ballot and is approved by voters, Colorado would become the first state to have such a ban.

Tim Farnum said he decided to push for the measure after watching his own children struggle with the mental effects of always having a smartphone around. "They would get the phones andlockthemselves in the room and change who they were," he told The Coloradoan newspaper.

State Senator John Kefalas, a Democrat, said he understands the reasoning behind the proposed law. However, he told The Coloradoan that a child's smartphone usage is a "family matter" and not something the government should decide. "Ultimately, this comes down to parenting,” he said, “making sure their kids are not putting themselves at risk.”

Last year, the AAP (the American Academy of Pediatrics) releasedguidelinesfor media use by children. The group advised parents to limit time spent watching videos to no more than one hour a day of high-quality programming until age 6. After that, it said, parents should set reasonable time limits for their children and make sure electronic devices do not take time away from sleep or exercise.

【1】What’s NOT right about Tim Farnum’s proposal?

A. It will be passed by the state of Colorado next year

B. It needs 300,000 signatures to gain the ballot

C. It bans buying smartphones for children under 13.

D. It bans selling smartphones to children under 13.

【2】What’s the driving force of Tim Farnum’s proposal?

A. Other parents’ request

B. His own children’s addiction to Smartphones

C. Smartphones’ harm to children’s health

D. The guidelines released by the AAp.

【3】What’s the attitude of John Kefalas toward Tim Farnum’s proposal?

A. Positive B. Doubtful

C. Disapproving D. Unconcerned

【4】From the last paragraph, we can infer that______

A. children under 6 shouldn’t watch videos

B. parents are to blame for children’s media use

C. parents should control children’s media use

D. electronic devices won’t affect children’s sleep

As is known to us, some students cheat in exams at school. As students, we often take exams at school, sometimes we have many exams that is too difficult for us. In addition, some of us are lazy and don’t work hard on our lessons. So when taken exams, we sometimes cheat in order to get good results to make our parents and teachers pleased.

In my opinion, it was wrong to cheat in exams because it breaks the rules of the schools. Our students should be honesty and try to get good results by studying hard instead of cheating in exams. What’s more, we should improve our method of study and make well preparations for exams. With the saying goes, “Nothing is impossible for a willing heart.

【題目】For years we have been told that encouraging a child’s self-respect is important to his or her success in life. But child experts are now learning that too much praise can lead to the opposite effect. Praise-aholic kids who expect it at every turn may become teens who seek the same kind of approval from their friends when asked if they want to go in the backseat of the car.

The implication(含義) of saying “You are the prettiest girl in class,” or talking about the goals she scored but not her overall effort, is that you love her only when she looks the best, scores the highest, achieves the most. And this carries over to the classroom.

Social psychologist Carol Dweck, PHD, tested the effects of over-praise on 400 fifth graders while she was at Columbia University. She found that kids praised for “trying hard” did better on tests and were more likely to take on difficult assignments than those praised for being “smart”.

“Praising attributes(品質(zhì)) or abilities makes a false promise that success will come to you because you have that quality, and it devalues effort, so children are afraid to take on challenges,” says Dweck, now at Stanford University, “They figure they’d better quit while they’re ahead.”

【1】The underlined words “Praise-aholic kids” refer to kids who are ______.

A. tired of being praised B. worthy of being praised

C. very proud of being praised D. extremely fond of being praised

【2】The author quoted Dr.Dweck’s words in the last paragraph in order to make the article ______.

A. better-known B. better-organized

C. more persuasive D. more interesting

【3】We can infer from the passage that _______.

A. praise for efforts should be more encouraged

B. praise for results works better than praise for efforts

C. praising a child’s achievements benefits his or her success in life

D. praising a child’s abilities encourages him or her to take on challenges
