20.I learned my first lesson from my grandparents when I was young.They both grew up in very large families and lived through the Great Depression.Saving for a rainy day was their life philosophy.Rather than seeking fulfillment through material items,they chose to spend really simple life together with their family.
   Over the years my grandparents notice dramatic changes in their community.Every year more farmland was destroyed to build larger and larger homes.As real estate(地产) prices rose,many of their neighbors sold their little homes and land.Soon theirs was the only small house surrounded by a sea of mansions.My grandparents built and lived in a small 600-square-foot cottage for most of their adult lives.Lots of family members encouraged my grandparents to expand their little old house.But they didn't want a bigger one.They loved their little house and were content with what they had.
   My grandparents avoided a consumptive  (浪费的 )  lifestyle by painting and repairing the house themselves.They lived in a small home,but had a huge garden.They loved gardening and planting because it reduced their grocery bill,improved their health,and gave them an excuse to be outside.They also reused and recycled many things.For in-stance.they had driven the same car for over 15  years and didn't buy a new one until the old Chevrolet was worn out.
   From my grandparents,I learned an important lesson:it is possible to live a simple life.My grandparents taught me that living a simple life isn't about self-deprivation(自我牺牲).Instead,it's about giving yourself the time,freedom,and money to pursue your dreams.Becoming debt free,downsizing to a smaller home,and going out on foot instead of by car are good ways to take control of your life and start pursuing your dreams.
56.The community's changes include all the following EXCEPT thatD
A.many mansions were built there       B.many neighbors sold their houses
C.the houses became more expensive     D.people built more farmland
57.The author's grandparents didn't expand their house becauseC
A.they didn't understand the family members'advice
B.their house was really new and large enough
C.they were satisfied with the house they lived in
D.they were too old to do any house-building job
58.Which of the following is a consumptive lifestyle in the grandparents'opinion?
A
A.Changing cars in a short time.
B.Planting vegetables in the garden.
C.Reusing and recycling things.
D.Repairing the house themselves.
59.Which can be the best title of this passage?D

B.My Grandparents
C.A Simple Lifestyle                 
D.A Lesson from My Grandparents.

分析 本文介绍了自己爷爷奶奶的生活方式是比较简朴的,虽然周围都建造了大的房子、过着富裕的生活,但是他们却一直倡导简单、朴素的生活,居住在自己的小房子里,不主张花钱换一辆新车等,这是作者从他们那学到的一个道理.

解答 56-59 DCAD
56.D.细节理解题.由第二段的第二句"Every year more farmland was destroyed to build larger and larger homes."可知A正确,mansion(大厦、公馆);"As real estate(地产) prices rose,many of their neighbors sold their little homes and land."可知B、C项正确,社区的改变不包括建造更多的农田;故选D.
57.C.推理判断题.由第二段最后一句"They loved their little house and were content with what they had."可知原因是他们对自己住的房子很满意.可推知,C项切题.
58.A.细节理解题.由第三段由"For instance,they had driven the same car for over 15 years and didn't buy a new one until the old Chevrolet was worn out."可知他们认为在短时间内换车是浪费的.故选A.
59.D.标题归纳题.文章主要介绍了作者爷爷奶奶的生活方式,从那学到了一个重要的道理.故D项作为文章标题最佳.

点评 本文属于故事类文章阅读,解答此类题目要认真阅读,迅速抓住故事的主题,了解故事发展的线索和脉络,根据题干的不同要求进行细致的分析,比如标题归纳题,要通读文章,抓住文中的主线,找出最适合文意的标题,要具有典型性和概括性等.

13.Medical drugs sometimes cause more damage than they cure.One solution to this problem is to put the drugs inside a capsule,protecting them from the body-and the body from them-until they can be released at just the right spot.There are lots of ways to trigger (引发) this release,including changing temperature,acidity,and so on.But triggers can come with their own risks-burns,for example.Now,researchers in California have designed what could be a harmless trigger to date:shining near-infrared light (NIR,近红外线) on the drug in the capsule.
The idea of using light to liberate the drug in the capsule isn't new.Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV,紫外线) or visible light.But tissues also readily absorb UV and visible light,which means the drug release can be triggered only near the skin,where the light can reach the capsule.NIR light largely passes through tissues,so researchers have tried to use it as a trigger.But few compounds (化合物) absorb NIR well and go through chemical changes.
That changed last year when Adah Almutairi,a chemist at the University of California,San Diego,reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light.Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB).When they catch the light,ONB groups fall off the polymer,leading to its breakdown.But ONB is only a so-so NIR absorber,and it could be poisonous to cells when it separates from the polymer.
So Almutairi and her colleagues reported creating a new material for capsules that's even better.This one consists of a long chain of compounds called cresol groups linked in a polymer.Cresol contains reactive(易反应的) components that make it highly unstable in its polymeric form,a feature Almutairi and her colleagues use to their advantage.After polymerizing the cresols,they cap each reactive component with a light-absorbing compound called Bhc.When the Bhcs absorb NIR light,the reactive groups are exposed and break the long polymer into two short chains.Shining additional light continues this breakdown,potentially releasing any drugs in the capsule.What's more,Almutairi says,Bhc is 10times better at absorbing NIR than is ONB and is not poisonous to cells.

6.Harvard researchers have created a tough,low-cost,biodegradable (可生物降解的) material inspired by insects'hard outer shells.The material's inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic.The material,made from shrimp ('虾) shells and proteins produced from silk,is called"shrilk."It is thin,clear,flexible and strong.
A major benefit of the material is its biodegradability.Plastic's toughness and flexibility represented a revolution in materials science during the 1950s and'60s.Decades later,however,plastic's very durability (耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags,or short-lived consumer goods,used in the home for a few years and then cast into a landfill where they will degrade for centuries.What is the point of making something that lasts 1,000years?
Shrilk not only will degrade in a landfill,but its basic components are used as fertilizer(肥料),and so will enrich the soil.
Shrilk has great potential,the inventors said.Materials from which it is made are plentiful in nature,found in everything ranging from shrimp shells,insect bodies to living plants.That makes shrilk low cost,and its mass production possible should it be used for products demanding a lot of material.
Work on shrilk is continuing in the lab.The inventors said the material becomes flexible when wet,so they're exploring ways to use it in wet environments.They're also developing simpler production processes,which could be used for non-medical products,like for computer cases and other products inside the home.They're even exploring combining it with other materials,like carbon fibers,to give it new properties.

C.major features
D.basic elements
67.What has become a concern about plastic?A

D.its raw materials are abundant in mature
69.What are the inventors doing in the lab?B
A.Replacing carbon fibers with shrilk.
B.Testing ahrilk's use in wet conditions.
C.Making shrilk out of used household goods.
D.Improving shrilk's flexibility for medical purposes.
70.Which of the following can be the best title for the passage?D
A.Recent Progress in Environmental Protection
