分析 本文主要論述了鍛煉身體的好處:第一,鍛煉可以幫助你處理工作、人際關(guān)系或生活中的壓力;第二,經(jīng)常鍛煉可能會(huì)讓你變得更聰明并且會(huì)減少你在你這個(gè)年齡喪失大腦功能的可能性;第三,定期的有氧運(yùn)動(dòng)可以提高睡眠質(zhì)量;最后,經(jīng)常鍛煉會(huì)使你會(huì)更健康,從而避免遭受病痛的折磨.

解答 答案:
51.because     考查句意理解以及從屬連詞    根據(jù)前一句"鍛煉可以幫助你處理工作、人際關(guān)系或生活中的壓力",可推測(cè)出本句解釋的應(yīng)是前一句的內(nèi)容,即:這可能是因?yàn)檫\(yùn)動(dòng)本身就是一種壓力形式,它會(huì)幫你的身體更好的處理它;此處用來(lái)引導(dǎo)原因狀語(yǔ)從句,意為:因?yàn);故用because.
52.who   考查關(guān)系代詞    本句為定語(yǔ)從句;由于先行詞 those(指那些人)在該從句中作主語(yǔ),故用關(guān)系代詞who.     
53.lower   考查形容詞的比較級(jí)    此處指的是兩者之間的比較,即將一周做三次30分鐘有氧運(yùn)動(dòng)的人與不做運(yùn)動(dòng)的人相比,他們面對(duì)壓力的反應(yīng)會(huì)更好,血壓會(huì)更低;故用lower.         
54.a(chǎn)       考查固定搭配    a little 意為:一點(diǎn)兒,少量;本句的意思是:即使是少量的運(yùn)動(dòng),從一個(gè)簡(jiǎn)單的10分鐘步行到劇烈的有氧健身操,似乎都會(huì)減少你的焦慮感;此處指的是:少量的運(yùn)動(dòng);故用a.
55.of     考查介詞      此處表達(dá)的是所有關(guān)系,用以構(gòu)成名詞的所有格,意為:焦慮的感受;故用of.
56.possibility    考查名詞    此處用在定冠詞the之后,作動(dòng)詞lessen的賓語(yǔ),意為:減少你在你這個(gè)年齡喪失大腦功能的可能性;故用名詞possibility.
57.a(chǎn)ctually       考查副詞   此處用來(lái)修飾動(dòng)詞help,故用副詞actually.
58.has been shown      考查時(shí)態(tài)及語(yǔ)態(tài)    根據(jù)時(shí)間狀語(yǔ)"In the last few years"可知,此處應(yīng)使用現(xiàn)在完成時(shí),由于主語(yǔ)it與動(dòng)詞show構(gòu)成被動(dòng)關(guān)系(意為:它已被證明),所以應(yīng)使用現(xiàn)在完成時(shí)態(tài)的被動(dòng)語(yǔ)態(tài);故用has been show.
59.exercising   考查固定搭配    keep doing sth.意為:繼續(xù)做某事,不斷地做某事;此處指的是:不斷地鍛煉;故用exercising.
60.to suffer    考查固定搭配    be less likely to do sth.意為:更不可能 …;此處指的是:當(dāng)你經(jīng)常鍛煉時(shí),你的身體功能只能會(huì)更好,你會(huì)更健康,就更不可能遭受身體上的痛苦了;故用to suffer.

點(diǎn)評(píng) 本題主要考查了各種語(yǔ)法在短文中的具體運(yùn)用.做本題時(shí),需要在正確理解短文的前提下,逐句分析句意以及所考查到的語(yǔ)法現(xiàn)象;因此在平時(shí)的學(xué)習(xí)中,應(yīng)熟練掌握各種語(yǔ)法知識(shí),其中包括詞法,句法,各種時(shí)態(tài)語(yǔ)態(tài)以及虛擬語(yǔ)氣等.

16.So you think you know your dog.But how well does your dog know you?She probably recognizes you when she sees you.But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face?Researchers in Austria have taught pet dogs to know the difference.
Dogs are very mindful of sound.When dog owners shout or speak in a strong,unkind voice,dogs often act ashamed and quietly move away from the area.
Recently,researchers found that dogs can look at our faces,and tell the difference between a smile and a frown(皺眉).The animals were able to recognize a look of praise from one of blame.
Researchers at the University of Veterinary Medicine,Vienna performed a series of experiments.They taught dogs to recognize facial expressions.They showed the dogs two pictures of either the upper or lower half of a person's face.On one picture,the person looked happy.The other appeared angry.
The dogs were then shown images of the eyes or mouths of people they had never seen before.They were also shown the left half of the faces used in training.
Corsin Muller led the study."We were really speaking,do they realize that smiling eyes have the same meaning as a smiling mouth,or angry eyes have the same meaning as an angry mouth?And it turned out that they really did perform very well in these research experiments."
Once the dogs learned to recognize which image was happy or angry,they could easily find the same expressions in pictures of any face.
Corsin Muller says future studies will try to show whether dogs can learn the meaning of facial expressions-for example,whether a frown shows that someone is angry.
In the experiments,researchers found the dogs were slower to link a reward,or prize,with recognition of the angry face.This suggested that dogs had an idea people with angry faces were best avoided.

29.What does the passage mainly tell us?D
A.How one can know his dog well.
B.How a dog can probably be well trained.
C.How a dog can tell one something.
D.whether dogs can recognize our facial expressions
30.Hearing its owner's strong,unkind voice,a dog is likely toC.
A.jump happily
B.a(chǎn)ct excitedly
C.escape quietly
D.shout loudly
31.A dog is able to recognize one'sD.
A.praise
B.blame
C.a(chǎn)nger
D.a(chǎn)ll of the above
32.What can we learn from the passage?B
A.Dogs are as clever as human beings.
B.Dogs can understand man's feelings.
C.Dogs can be trained to do everything.
D.Dogs can learn to make any angry face.
