9.We all have an idea about the common types of environmental problems.However,light pollution may be a new term to many of us.But,the fact is,it does affect mankind,other living forms and the environment as a whole.
What is light pollution?It presents all forms of misused man-made light.The obvious cause of light pollution is the use of outdoor lighting products improperly.It can be office lighting,car headlights,station lights,streetlights and many more.
Light pollution is harmful to both animals and plants.Upon studies,it is found that obvious effects  are observed in the behaviour of nocturnal animals.Needless to mention,bright light at night makes it difficult for these animals to hunt,wander and perform their regular activities.Light pollution is directly or indirectly responsible for causing several diseases.Its effects are related to disturbance in the physical rhythm.It contributes to risks of developing cancerous cells.So,it's nothing less than a threat to human health.
You have already seen the negative effects of light pollution on animals and human health.Apart from this,the actual cost of misused light is about millions of dollars every year.It also leads to the release of greenhouse gases and global warming.After all,fuels are used for producing electricity.
While outdoor lighting and using man-made lighting products are part of our modern lifestyle,some simple ways will surely help in reducing light pollution.For example,while installing outdoor lighting,make sure that they are pointed downwards.Also,use only the required lighting equipment for both home and offices.Believe it or not,many people living in the urban areas cannot view clear sky and stars at night.Let's contribute our part in reducing the pollution.

32.What can we learn about light pollution?A
A.It is a negative fruit of light technology.
B.It has no effect on plants
C.It contributes to most cancers.
D.It affects animals'normal activities in the daytime.
33.How does light pollution affect the climate?D
A.It reduces temperatures by days and makes nights warmer.
B.It creates more clouds over parts of the Earth.
C.It stops the release of greenhouse gases.
D.It causes global temperatures to go up.
34.How can we contribute our part in reducing light pollution?B
A.Forbid the use of outdoor lighting.
B.Don't use unnecessary lights at home and offices.
C.Reduce money spent on man-made light in urban areas.
D.Use clean energy to produce electricity.
35.It can be inferred from the last paragragh thatC.
A.Citizens should be forbidden to install outdoor lighting.
B.Only simple ways can help reduce light pollution.
C.Light pollution needs to be dealt with urgently.
D.There is no clear sky or stars over the urban areas.

分析 本文是科普说明文.主要介绍了光污染的定义、造成的危害及防治建议等.

解答 ADBC
32.A 根据第二段可知,光污染是滥用各种人造光源而形成的,即不恰当地使用户外照明产品,可以是办公照明、汽车车灯、方位灯、路灯等.由此推断,光污染可以说是光技术的坏影响.
33.D 由第四段"It also leads to the release of greenhouse gases and global warming."可知,光污染会造成更多温室气体的排放,从而引起全球变暖,D项符合文意.C项与文意相悖,A、B项无依据.
34.B 根据最后一段"Also,use only the required lighting equipment for both home and offices."
可知,在家里和办公室里只用必需的照明产品便可减少光污染,应选B项.
35.C 由文章最后两句,尤其是"Beleve it or not,many people living in the urban areas cannot view clear sky and stars at night"可知,光污染非常严重,据此推知光污染问题有待解决,应选C项,其他选项均与文章不符.

点评 做阅读时经常犯错的主要原因是,仅凭读过文章后残留在脑海中的一丝印象来勾选答案,这样便很容易掉入出题人故意设布下的题目陷阱.所谓阅读理解,对于题目的理解一定要忠实于原文,因此,每一道题都应该与原文作全面的对比与核查,再得出答案.也就是说,阅读理解的每一道题目,在原文都应该有明确的出处,我们把这一出处叫做原文相关句,(1)排除与原文相关句主题不一致的选项(2)排除与原文相关句态度相反的选项  (3)排除用于过于极端或负面的选项(4)注意结合文章主旨和主题去排除.

19.Seven Health Facts about Coffee
When you're considering your morning coffee,here are some health facts to keep in mind:
1.Coffee Reduces Your Risk of Diabetes (糖尿病)
In a 2005review of nine studies,researchers found that for those that drank four to six cups of coffee per day,versus only two or fewer,their risk for Type 2diabetes decreased by almost 30percent.The number decreased by 35percent when people drank more than six cups per day.And if you're picturing yourself running around the office with your eyes bugging out of your head,no worries because caffeinated and decaffeinated coffees provided much the same results.
2.Coffee Fights Free Radicals (自由基) Ks*5u
We often forget that coffee is actually a plant and like all plant foods,the coffee bean contains more than 1,000naturally occurring substances called phytochemicals,which may help prevent disease.Many of these phytochemicals are antioxidants which protect the cells from damage from free radicals.
3.Coffee Improves Memory and Cognition
Researchers reported that volunteers who drank caffeinated coffee in the morning performed better than nondrinkers on tests that involved learning new information.Coffee can also improve cognitive function as we age.One study found that combining coffee with a sweet treat had an even bigger impact.
4.Coffee Can Increase Osteoporosis (骨质疏松)
It's true that coffee can cause the body to excrete calcium in urine.We don't want the body to rid itself of calcium because this can lead to osteoporosis.According to The Diet Channel,about five milligrams of calcium is lost per every six ounces of coffee consumed.But these calcium losses can be counter balanced with two tablespoons of milk or yogurt per cup of coffee.
5.Coffee Causes Wrinkles
Even though coffee has antioxidants,if you drink too much of it,it can cause wrinkling of the skin.This is a result of dehydration (脱水) which is the worst thing for your skin.So when you're drinking that morning cup or two,make sure that you're pairing it with water.Even better,add one tablespoon of chia seeds to your water and let them sit for 30minutes.The chia seeds keep you even more hydrated than regular water.
6.Coffee Can Actually Cause Weight Gain
The blood sugar changes that a caffeine high produces can contribute enormously to a strong desire for it,according to iVillage.Coffee is also socially connected to food.For example,we pair coffee with dessert or that morning powdered doughnut.Additionally,when we crash from our caffeine high that's when we reach for all sorts of fatty snacks to keep us going.
7.Conventional Coffee Is Laden with Pesticides (杀虫剂)
The coffee plant is one of the most heavily sprayed crops.It's coated with chemicals,pesticides,and herbicides,nothing you'd want to be swallowing.If you do drink coffee,make sure that it's the organic variety,free from assorted chemicals that leech into our ground water and can make us sick down the road.
If you switch to decaffeinated coffee,make sure the caffeine (咖啡因) is removed in a natural way without the use of chemicals to do it.Often times,conventional decaffeinated coffee has more chemicals than regular.

41.If you want to decrease the risk of diabetes by 35%,you need to take at leastA cups of coffee every day.
A.seven  B.six  C.five  D.four
42.If you are a heavy drinker of coffee,a far better way to avoid wrinkling of your skin is to drink waterD.
A.less than usual  B.regularly  C.with sugar  D.with chia seeds
43.Which of the following statements is wrong?B
A.Adding two spoons of milk to a cup of coffee can prevent calcium losses.
B.Decaffeinated coffee has different effects from caffeinated coffee as to diabetes.
C.Many phytochemicals protect the cells from damage from free radicals.
D.The organic variety of coffee plant is free from assorted chemicals.
44.The author has a/anC attitude towards drinking of coffee.
A.positive  B.negative  C.objective  D.imaginative.
17.Born in Amherst,Massachusetts,to a successful family,Elizabeth Dickinson was an American poet.She studied at Mount Holyoke Female Seminary before (61)returning(return) to her family's house in Amherst where she lived (62)a peaceful life.She kept in touch with her friends by writing letters and was (63)unwilling(willing) to greet guests or,later in life,even leave her room.
Dickinson's poems are unique(独一无二的) for the time she lived in; they contain short lines,typically lack titles,and often use half rhyme.Many of her poems deal (64)with themes(主题) of death and immortality(永生).Dickinson wrote about 1,800poems during her lifetime,but few of (65)them were published.Although most of her friends probably knew about Dickinson's writing,they didn't know (66)that she had produced so many poems until after her death in 1886,when her younger sister Lavinia discovered the place where the poems were hidden.(67)If her sister had not discovered them,the broadness of Dickinson's work wouldn't have become known.
Dickinson's first collection of poetry was published in 1890,the content(内容) of (68)whichwas heavily edited(编辑) by the publishers (69)to fit (fit) the conventional poetic rules of the time.A complete and mostly unedited collection of her poetry became available for the first time in 1955.Now Dickinson (70)is considered (consider) to be one of the most important American poets.

The mother replied,"When my son was a baby,he was in a room that caught on fire.Everyone was too(47)B to go in because the fire was out of control,so I went in.(48)B  I was running towards his bed,I saw a beam(横梁) coming down and I placed myself (49)D trying to protect him.I was (50)B unconscious(失去知觉) but fortunately,a fireman came in and (51)?D?βοτηοφυσ,"σηετουχηεδτηε(52)Aside of her face."This scar will be permanent(永久的),but to this day,I have never (53)D doing what I did."?
At this point,the little boy came out (54)B towards his mother with tears in his eyes.He held her and felt a great  (55)A of the sacrifice(牺牲) that his mother had made for him.He held her hand tightly(紧紧地) for the rest of the day.

12."If music is the medicine of the soul(灵魂),let it play on,"said a famous person.I think he said so because probably he got some help from music.Music has some strange abilities.Medical scientists have found that a person that feels stressed can actually listen to some kind of music and become well.
The researchers said that since stress comes as a result of life events such as starting a new family,starting a new business,and starting a new job,one can actually listen to good music and feel good because good music touches the human mind in a positive way.Music helps you to forget the life events that make you worried and remember the important events that once happened in your life.
Depression(抑郁) is a disease cause by stress,smoking,social problems and so on.Depression is also caused by problems such as failure in business.Depression may bring us weakness,headache,and loss of concentration.Good music makes one remember happy moments or good days.If you play music about love,it makes you feel like falling in love again though you may have had several upset experiences.And such good feeling make you healthy.
Anxiety(焦虑) is another health problem that can be controlled by music.Anxiety is a side effect of some major health problems such as cancer of the liver and cancer of the breast.Good music makes you feel relaxed and removes the pains from these diseases and you feel all right.
Good music can send you to sleep.And you need to know that sleep puts your body in a healthy condition.Sleep takes away the effects of stress,depression and anxiety from a person.
