【題目】 As individuals age, many will experience decreased memory abilities.【1】Some signs include forgetting phone numbers, misplacing car keys, and struggling with name recall. This decline is associated with a routine that leaves parts of the brain unused. Memory exercises can help keep typically unused parts of the brain active and improve memory abilities.

【2】It can be something as simple as going to a new restaurant for lunch, cooking something completely new, or visiting a friend in the next town for the weekend. New sensory stimulation can help refresh memory.

Another easy way to improve memory is to use one's non-dominant hand to do simple tasks. For example, if one is right-handed, the left hand could be used to brush teeth or comb hair.【3】But in fact, a part of the brain is being used that is rarely put to work, making the brain stronger.

【4】This might include studying a new language or researching how to do a math problem. And it does not have to be something traditionally thought of as brain stimulating. Learning a new craft or sport may also activate the brain in new ways.

Not only can mind exercises improve memory, but physical exercise can as well. Studies show that exercise can improve memory abilities as it increases blood circulation and therefore more oxygen can reach the brain.【5】

A.This may feel slow and ineffective.

B.Short-term memory is often the first to suffer.

C.Talking with others can also improve one's memory.

D.Even as little as 30 minutes of walking each day can help.

E.Memory exercises can also be accomplished by learning new things.

F.One type of memory exercise involves changing one's regular routine.

G.Being alone can cause stress and depression，which affects memory negatively.

【答案】

【1】B

【2】F

【3】A

【4】E

【5】D

這是一篇選句填空。隨著年齡的增長(zhǎng)，許多人的記憶能力會(huì)下降。文章介紹了幾種提高記憶力的方法。

【1】根據(jù)上文As individuals age, many will experience decreased memory abilities.可知隨著年齡的增長(zhǎng)，許多人的記憶力會(huì)下降。由此可知，本句應(yīng)當(dāng)承接上文說(shuō)明人哪方面的記憶最先受到損害。故B選項(xiàng)“短期記憶往往最先受到損害的”符合上下文語(yǔ)境，故選B。

【2】根據(jù)后文It can be something as simple as going to a new restaurant for lunch, cooking something completely new, or visiting a friend in the next town for the weekend. New sensory stimulation can help refresh memory.可知它可以是一些簡(jiǎn)單的事情，比如去一家新餐館吃午飯，烹飪一些全新的東西，或者周末去拜訪另一個(gè)城市的朋友。新的感官刺激可以幫助刷新記憶。由此可知，本段說(shuō)明的記憶訓(xùn)練是指改變一個(gè)人的日常規(guī)律來(lái)進(jìn)行的。故F選項(xiàng)“一種記憶訓(xùn)練包括改變一個(gè)人的日常規(guī)律”符合上下文語(yǔ)境，為短文標(biāo)題。故選F。

【3】根據(jù)上文For example, if one is right-handed, the left hand could be used to brush teeth or comb hair.可知例如，如果一個(gè)人是右撇子，左手可以用來(lái)刷牙或梳頭。以及后文But in fact, a part of the brain is being used that is rarely put to work, making the brain stronger.可知但是事實(shí)上，大腦的一部分很少被使用，這使得大腦更強(qiáng)壯。由此可知，本句應(yīng)當(dāng)承接上文說(shuō)明上文這種做法給人的 感受是：可能會(huì)讓人覺(jué)得緩慢和無(wú)效，但是實(shí)際上可以讓大腦更強(qiáng)壯。故A選項(xiàng)“這可能會(huì)讓人感到緩慢和無(wú)效”符合上下文語(yǔ)境，故選A。

【4】根據(jù)后文This might include studying a new language or researching how to do a math problem. And it does not have to be something traditionally thought of as brain stimulating. Learning a new craft or sport may also activate the brain in new ways.可知這可能包括學(xué)習(xí)一門(mén)新語(yǔ)言或研究如何做一道數(shù)學(xué)題。它并不一定是傳統(tǒng)意義上的大腦刺激。學(xué)習(xí)一門(mén)新手藝或運(yùn)動(dòng)也可能以新的方式激活大腦。由此可知，本段說(shuō)明的是通過(guò)學(xué)習(xí)新事物來(lái)進(jìn)行記憶練習(xí)。故E選項(xiàng)“記憶練習(xí)也可以通過(guò)學(xué)習(xí)新事物來(lái)完成”符合上下文語(yǔ)境，為短文的標(biāo)題。故選E。

【5】根據(jù)上文Studies show that exercise can improve memory abilities as it increases blood circulation and therefore more oxygen can reach the brain.可知研究表明，鍛煉可以提高記憶能力，因?yàn)樗梢栽黾友貉h(huán)，因此更多的氧氣可以到達(dá)大腦。由此可知，本句為本段最后一句，有承接上文的作用，上文提到了鍛煉可以提高記憶能力，可知本句應(yīng)當(dāng)是舉出實(shí)際鍛煉的時(shí)間來(lái)說(shuō)明上述觀點(diǎn)。故D選項(xiàng)“即使每天步行30分鐘也會(huì)有所幫助”符合上下文語(yǔ)境，故選D。

【題目】 Although most people believe that owning a business or working on an idea means you are an entrepreneur (企業(yè)家), the reality is that entrepreneurship is so much more than just these two things. It is about the ability to innovate (創(chuàng)新) by helping society progress. For those who aspire to become real entrepreneurs, the path to turn your thought into entrepreneurship is one that requires you to know yourself.

Recognize what skills you are good at. Everybody wants money. But many fail to realize that money is the extension ( 延伸) of your skills, so the most important aspect of learning to make money starts by knowing what skills you have. Make a list of your skills and you should see where your strengths lie. The goal with this exercise is to recognize what skills you are good at naturally. Make good use of them until you finally change more of your skills into usable abilities for your business.

Make use of your confidence to create belief. Confidence is a result of repeating one thing. The more you practice doing something, the more confident you become in the process needed to see it to the end. Starting a business requires confidence, so most people who have zero confidence in the process fail to get started because it is an unknown area. You have to believe in the idea, the process and the ability within yourself to bring your business project to life. Without confidence, belief doesn't exist; without belief, the chances of giving up are high.

Allow your love to become enthusiasm. The last ingredient outside of your skills and confidence is the ability to focus on ideas that you feel enthusiastic about. Having passion will push you to struggle for something you love and turn that longing into action. The goal is to identify topics of interest so that you can start showing some aspects of passion as you start your project. The closer a project is to your heart, the less pessimistic you will become when results don't go your way.

【1】What can we learn from Paragraph 2?

A.It is very difficult for us to know our skills.

B.Knowing your skills is the first step to learn to make money.

C.To recognize your skills will surely make your business successful.

D.To recognize your skills is more important than making money.

【2】What's the importance of enthusiasm for us?

A.It can help us find out what we love.

B.It can make us never feel pessimistic.

C.It can push us to work hard on our goals.

D.It will make us succeed in whatever we are doing.

【3】What does this passage mainly talk about?

A.The advantages of confidence.

B.The ability to focus on ideas.

C.Why people want to be an entrepreneur.

D.How you can go from ideas to an entrepreneur.

科目：高中英語(yǔ) 來(lái)源： 題型：

【題目】 Although you can possibly get by as a tourist in weeks, mastering a language is a long-term commitment taking years, not months. The FSI has classified languages in degrees of difficulty for English speakers. Chinese takes approximately 88 weeks or 2,200 hours ranking top 5 along with Arabic, Korean and Japanese.

Each Chinese dialect is effectively another language but Mandarin(Putonghua in Chinese, which means the common language)is considered the official tongue in modern China. They all share roughly one evolving writing system, referred to as written language invented for administering a large, diverse empire.

To complicate(使復(fù)雜)the matter further, there are two main types of written Chinese characters under the same writing system: the traditional Chinese used in Hong Kong and Taiwan and the simplified Chinese in mainland China. For example, fly is written as 飛 in traditional Chinese and 飛 in simplified Chinese. They’re basically the same character written in two different ways but pronounced differently when spoken in different dialects.

Each written word when spoken is mutually incomprehensible between a Mandarin speaker in Beijing and a Cantonese speaker in Hong Kong. If you think that’s odd, consider our number system: the symbol “9” is universally recognized but it’s pronounced “nine” in English and “devet” in Slovenian.

Every word must be memorized separately as you can’t guess its pronunciation from the script-but one could say the same of English if you consider plough, dough and tough.

Meanwhile, dictionaries list words according to stroke(筆畫(huà))count. These go from one to over 60 strokes. The archaic character zhé- which appropriately, means “verbose” - has 64 strokes.

And then there are the pronunciation challenges. There are four tones in Mandarin: high pitch (say G in a musical scale), rising pitch(like from C to G), falling(from G to C)and falling low then rising(C to B to G)- and if you think that’s difficult, there are nine tones in Cantonese. In Mandarin, there is a whole poem, “The Lion-Eating Poet in the Stone Den” with just the syllable “shi” repeated 107 times in various tones. In other words, if you are tone-deaf you might as well give up now.

【1】What do all Chinese dialects have in common?

A.They were invented by the emperor.

B.They have the same writing system.

C.They evolve in the same way.

D.They serve the same purpose.

【2】Why does the author mention the symbol “9” in Paragraph 4?

A.To prove different pronunciations of Chinese dialects

B.To indicate the similarities in all languages.

C.To show that Chinese is an odd language.

D.To compare English with Slovenian.

【3】What challenge does the author think is difficult to overcome?

A.Complicated scripts and strokes.

B.Different types of characters.

C.Various tones.

D.Too many dialects.

【4】What is the main idea of this passage?

A.Chinese has different dialects.

B.Chinese is very difficult to learn.

C.Chinese is an ever-developing language.

D.Chinese sounds like music and poems.
