【1】amazing

【2】that/which

【3】running

【4】and

【5】strength

【6】more

【7】why

【8】to find

【9】The

【10】be filled

【解析】

【1】amazing 考查形容詞。把人的身體看作一個(gè)令人驚奇的機(jī)器，修飾machine，故填-ing形式的形容詞amazing。

【2】that/which 考查定語(yǔ)從句。食物就是保持機(jī)器運(yùn)轉(zhuǎn)的燃料。此處為定語(yǔ)從句，修飾先行詞fuel，且從句中缺主語(yǔ)，故填that/which。

【3】running 考查動(dòng)詞短語(yǔ)。keep sb．/sth．doing保持…一直做…，故填running。

【4】and 考查連詞。both．．.and...固定句型。

【5】strength 考查名詞。太陽(yáng)的能量是很強(qiáng)的，它在進(jìn)入植物的時(shí)候會(huì)損失很多的力量。前面有形容詞性物主代詞its修飾，故填strength。

【6】more 考查形容詞的比較級(jí)。根據(jù)后句中的than可知，此處應(yīng)使用比較級(jí)，故填more。

【7】why 考查表語(yǔ)從句。這就是為什么吃水果和蔬菜有益于身體，故填why

【8】to find 考查非謂語(yǔ)動(dòng)詞。動(dòng)物也會(huì)使用其能量尋找植物。此處為不定式作目的狀語(yǔ)，故填to find。

【9】The 考查冠詞。句意：第二個(gè)動(dòng)物會(huì)花很多的能量去追捕第一個(gè)動(dòng)物。序數(shù)詞前加定冠詞The。

【10】be filled 考查被動(dòng)語(yǔ)態(tài)。就像一輛汽車(chē)需要被裝滿汽油一樣。have to后面接動(dòng)詞原形，故填be filled。

【題目】House Sitting

In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel. After people retire, they might buy a van and travel all over the country. 【1】 (many people—retired people—thousands of them)

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yards and they need cleaning. 【2】 I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

【3】 There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time. 【4】 You need to be good with pets, able to care for cats and dogs, or other pets they may have.

Some house sitting jobs are just for a few days or a couple of weeks while the home owner has a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.

【5】 Then you can travel to many different countries and stay there. One of the important things to get are references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to prospective house sitting jobs and they know you will do a good job.

A. I have done house sitting many times.

B. Thousands of people do this all the time.

C. It is also possible to do house sitting in other countries.

D. Generally you have many opportunities to get a house sitting job.

E. You must take a little care over what your description says about you.

F. This is an international house sitting service for all city and country areas.

G. You must have a good car, so you can travel to different parts of the country.

【題目】Regret can be a terrible addiction.Those who suffer from it so often become bitter and full of self-pity.It is an emotion that serious entrepreneurs（企業(yè)家）cannot afford,they must keep moving ahead and should not look back.As Alexander Graham Bell,inventor of the telephone said: when one door closes,another opens,but we often look so long and so regretfully upon the closed door that we do not see the one which has opened for us.

Entrepreneurs must learn to manage the conflict between constant experiment,which means lots of painful mistakes and a fear of failure,which can lead to paralysis（能力喪失）.

Likewise,past glory can be a killer.For example,Greg Dyke,who is a clever fellow,still looks back too much to his resignation as director-general of the BBC.He should move on and stop complaining about the injustice of it all. And Tim Waterstone should give up trying to buy back his bookshop chain,which he finally left more than lo years ago.He has tried to repurchase it at least five times.

By all means treasure experience and learn from your failure,but don't put yourself in the past sadness.Rather,go ahead and seize the day no matter what it is.I have little time for those who say: I wish I had started my own business. My only response is: so do it now.

【1】According to Paragraph 1,regret can make one feel .

A. bitter and self-pity B. upset and hopeless

C. disappointed and scared D. confident and brave

【2】It can be concluded from Bell's words that .

A. one should learn from others B. shouldn't forget the past

C. one should keep moving ahead D. life often gives us many challenges

【3】When entrepreneurs face conflict,they will experience .

A. arguments and failure B. mistakes and fear

C. choices and changes D. encouragement and confusion

【4】What is the main idea of the text?

A. One should feel regret about the past.

B. One should give oneself opportunity.

C. One should act now and look into the future.

D. One should be confident about the past.

【題目】Most parents and teachers want children to be happy. To that end, parents find themselves doing things for kids to make them happy, like buying gifts, taking them for ice cream, playing games together, or helping with homework.

Teachers are constantly doing things for children, too, like bringing treats to class, planning fun trips, and supporting students in other immeasurable ways.

Do acts of kindness toward children make us happier parents and teachers? Of course they do.

Unfortunately, we don’t make children happy by simply enabling them to be receivers of kindness. We increase their feelings of happiness and well-being by teaching them to be givers of kindness.

The truth is that children are born to be altruistic. But somewhere between birth and 4th grade, they are socialized to think more about themselves than others.

How do we change this and improve children’s well-being?

A recent study, Kindness Counts, conducted by researchers from the University of British Columbia and the University of California, broke new ground by showing the benefits gained by teens when they were taught happiness-increasing skills.

For a month, several hundred 9-11-year-olds performed and recorded three acts of kindness each week for anyone they wished. Another several hundred kept track of three pleasant places they visited during the week.

Not surprisingly, the results were consistent with adult studies. When kids performed acts of kindness or took notice of the pleasant places they visited during the week, they significantly increased feelings of happiness and satisfaction.

But hose who performed acts of kindness received an additional benefit. Measuring how well children were liked or accepted by their peers（同伴）, the study showed those who performed acts of kindness gained an average of 1.5 friends during the four-week period ---- good support for the idea that “nice guys finish first.”

【1】What do most parents and teachers do to make children happy?

A. Do good deeds for them.

B. Take them to see funny things.

C. Teach them the secret of happiness.

D. Develop their happiness-increasing skills.

【2】The underlined word “altruistic” in Paragraph 5 is closest in meaning to “ ”.

A. optimistic B. energetic

C. curious D. generous

【3】What can be concluded from the study?

A. Children can change their attitude easily.

B. Happy people are likely to do good deeds.

C. Acts of kindness are the key to happiness.

D. Visits to places lead to much more happiness.

【4】What does the underlined part “additional benefit” in the last paragraph refer to?

A. Winning support from teachers.

B. Broadening their social circle.

C. Showing respect for others.

D. Getting higher test scores.
