4.Cleaning your plate may not help feed hungry children today,but the timeworn advice of mothers everywhere may help reduce food waste from the farm to the fork,help the environment and make it easier to feed the world's growing population.
Hard data is still being collected,but experts in Chicago said about 30% to 50% of the food produced in the world goes uneaten.The average American throws away 33 pounds of food each month-about $40 worth,which means each person throws away almost 400 pounds of food.The US Department of Agriculture says that 23% of eggs and an even higher percentage of produce ends up in the trash.
"We forget we have all these fresh fruits and vegetables,and at the end of the week we have to throw them away",said Esther Gove,a mother of three young children in South Berwick,Maine."Now,I don't buy as much fresh produce as I used to."
But the effect of food waste arrives far beyond the kitchen.Agriculture is the world's largest user of water,a big consumer of energy and major emitter of greenhouse gases during production.Experts say reducing waste is a simple way to cut stress on the environment and can ease pressure on farmers,who will be called on to feed an expected 9 billion people around the world in 2050,compared with nearly 7 billion today.
No matter how sustainable (可持續(xù)的) farming is,if the food's not getting eaten,it's not sustainable and it's not a good use of our resources.In richer nations,fruit and vegetables end up in the trash because they aren't pretty enough to meet companies'standards,have gone bad in a home refrigerator or aren't eaten at a restaurant.In developing countries,much food spoils before it gets to market due to poor roads and lack of refrigeration.High food prices are another reason,since some people can't afford the food that's produced.

A.is you mother's best advice for you
B.can solve certain problems for the world

分析 本文主要講述了世界各國都存在的一個普遍現(xiàn)象--食物浪費,以及其會給社會帶來的各方面的影響.

解答 29.B 細(xì)節(jié)題.根據(jù)文章內(nèi)容 the timeworn advice of mothers everywhere may help reduce food waste from the farm to the fork,help the environment and make it easier to feed the world's growing population.由此可知,光盤行為不僅可以節(jié)約食物,而且還可以幫助減少食物浪費,減輕環(huán)境壓力以及更容易使得整個上漲的世界人口得到糧食,結(jié)合選項,故選B
30.D  詞義猜測題.根據(jù)文章內(nèi)容Agriculture is the world's largest user of water,a big consumer of energy and major emitter of greenhouse gases during production.農(nóng)業(yè)是這個世界上使用水最多的一種情況,在此期間,大量的能源會消耗以及大量的溫室氣體會產(chǎn)生,結(jié)合選項,故D符合文意.
31.A 推理題.根據(jù)文章內(nèi)容,主要講述了可持續(xù)的飲食方式,人們在外就餐時可以點足夠吃的食物,但對于沒有吃完的部分,應(yīng)該打包帶走,那樣既不浪費也不污染環(huán)境,結(jié)合選項,故選A
32.B 推理題.根據(jù)文章最后一段內(nèi)容In richer nations,fruit and vegetables end up in the trash because they aren't pretty enough to meet companies'standards,have gone bad in a home refrigerator or aren't eaten at a restaurant.In developing countries,much food spoils before it gets to market due to poor roads and lack of refrigeration.講述到在發(fā)達(dá)國家和發(fā)展中國家都存在的食物浪費現(xiàn)象,由此下文應(yīng)該會針對減少浪費這一話題而展開,結(jié)合選項,故選B

點評 本文是科教類閱讀理解.做這類題材閱讀理解時要求考生對文章通讀一遍,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù)

17.My wife,daughter,and I moved into our home nine years ago and we spent a lot of time and energy in the yard to get it looking like it does today.We live on a corner,higher than street level,and the entire side of the yard is surrounded by a professionally built rock wall.The front of the house though is another story because instead of a wall along the sidewalk,the rocks appear to be just thrown up onto the dirt as if someone were in a hurry to finish.
We did the best we could with what we had to work with and called this area our"rock garden".Whenever we had leftover flowers or plants,Denise or I would stick them out front,just to bring some color to the area.We would do all of the yard work on our own,even the tiring weed-pulling.
Last summer I had reached the end of the rock garden and found a tiny little plant that I could not immediately identify,I knew I didn't plant it and Denise claimed that she didn't either.We decided to let it continue growing until we could figure out what it was.
Weeks passed and as I made my way back to the mystery plant,it appeared to be a Sunflower with a tall skinny stalk(莖,桿) and only one head on it.I decided to baby it along and weed around it.As I pulled rocks from the area to get to the weeds,I noticed something unusual.The Sunflower had not started where I saw the stalk begin.It actually had begun under a big rock and grown under and around it to reach the sun.
That's when I realized that if a tiny little Sunflower didn't let a big rock stand in its way of developing,we too have the ability of doing the same thing.Once our environment begins to see that we believe in ourselves like that little Sunflower,we can attain the same nourishment(營養(yǎng)) and growth as well.
Stand tall like the Sunflower and be proud of who and what you are and the environment will begin to support you.You will find a way to go under or around your big obstacle in order to reach your desires.

25.Why is the front of the house another story according to the author?D
A.The workers finished it in a hurry.
B.There is a wall along the sidewalk.
C.The family view it as a rock garden.
D.The rocks are piled there at random.
26.The author found it unusual thatA.
A.the Sunflower grew under and around a big rock
B.the Sunflower had a tall stalk and only one head
C.the mystery plant turned out to be a Sunflower
D.a(chǎn) rock stood in the way of the flower's growth
27.Which of the following best describes the Sunflower?B
A.Brave and stubborn.
B.Confident and persistent.
C.Optimistic and modest.
D.Mysterious and devoted.

9.As a child,I was generally happy,singing and dancing to my favorite songs,smiling and laughing with my friends and family.But as far back as second grade,I noticed a"darkness"about me.I didn't enjoy participating in many things.
In middle school things in my life began to get even worse.I began withdrawing from everything I once enjoyed.I was always tired.Everything was horrible.Finally,midway through eighth grade,I was told I had a chemical imbalance,diagnosed (診斷) with clinical depression,and had to take medicine.It took months for me to feel the effects of the medicine.
When I began to feel happy again is when I realized that I had to take the responsibility for getting better myself,rather than relying on medicine.Aristotle said,"To live happily is an inward power of the soul,"and I believe that this quote describes what I had to do to achieve happiness.Happiness is a journey.Everyone seems to need different things to be happy.
"The essentials (要素) to happiness are something to love,something to do,and something to hope for,"a quote from William Blake sums up what I believe people need to realize to be truly happy in life.People need love; I feel they need their family and their friends more than anything else in the world.People need work to do,something to make them feel they are making a difference in the world.People need to know that more good is to come in the future,so they continue to live for"now"instead of constantly worrying about the bad that could come.Love and hope are happiness.

28.What do we know about the author in Paragraph 2?D
A.He hated going to sleep because he couldn't sleep well.
B.He spent months recovering from the clinical depression.
C.He was diagnosed with clinical depression in Grade Seven.
D.He suffered a great deal from clinical depression.
29.Who helped the author to be happy again?C
A.The author's friends.B.Aristotle.C.The author himself.D.William.
30.Which of the following about being truly happy is unnecessary in the author's opinion?B
A.Love.B.Ambition.C.Hope.D.Work.
31.What may be the best title for the text?A
A.The Essentials to Happiness
B.Ways to Overcome Shortcomings
C.Everyone Needs to Be Happy 
D.Happiness Is Love.

Dear editor,
I am glad to find more and more public bicycles are provided in the street for people to rent.
However,problems also arise.The bicycles are left almost everywhere at will in the street.Also,many people ride the bicycles on the driveway,causing a lot of traffic accidents.Worse still,damages have been found on some new bicycles.My suggestions on how to improve the situation are as follows.
First of all,Parking lot should be designed and decided on certain specific areas in the street,In this way,fewer people will leave the bicycle as they please.Secondly,more roads for bicycles need to be provided.
I hope this bicycle renting project will help build better traffic and improve the air quality in the city.
Yours
Li Hua.

Scientists claim to have developed a revolutionary new giant 3D concrete printer that can build a 2,500-square-foot house in just 24 hours.

The 3D printer, developed by Professor Behrokh Khoshnevis from the University of Southern California, could be used to build a whole house, layer by layer, in a single day.

"It is basically scaling up 3D printing to the scale of building," said Khoshnevis.

The giant robot replaces construction workers with a nozzle (噴嘴), which can quickly build a home based on a computer pattern, MSN News reported.

Contour Crafting, as it is named, is a layered fabrication (構(gòu)造) technology. Using this process, a single house or a colony of houses, each with possibly a different design, may be constructed in a single run, embedded (嵌入) in each house all the wires and pipes for electrical, plumbing and air-conditioning.

The potential applications of this technology are far-reaching including in emergency, low-income, and commercial housing.

"Our research also addresses the application of Contour Crafting in building habitats on other planets. Contour Crafting will most probably be one of the very few feasible approaches for building structures on other planets, such as the Moon and Mars, which are being targeted for human habitation before the end of the new century," researchers said on the project website.

The technology may potentially reduce energy use and emissions. And the main advantages of the Contour Crafting process over existing technologies are the superior surface finish that is realized and the greatly increased speed of construction.

1.Professor Khoshnevis has recently developed a 3D printer that can ________.

A. build a 2500-square-foot house in a single day

B. construct a skyscraper, layer by layer

C. design a group of houses automatically

D. assist construction workers in their work

2.The new 3D printer uses the following to build a house EXCEPT ________.

A. a nozzle B. a computer pattern C. a robot D. an air-conditioner

3.According to the text, the potential applications of Contour Crafting include building _______.

A. emergency vehicles B. low-income housing

C. commercial centers D. space stations on other planets

4.What advantages of this new technology is mentioned in the text?

A. It creates more jobs. B. It is less time-consuming.

C. It saves the building cost. D. It emits no carbon dioxide.
