2.Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger,but we also affect our water supply in less obvious ways.You may wonder how paving(鋪砌) a road can lead to less useable fresh water.A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It come from underground.The more roads and parking lots we pave,the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺).Driver climates are of course more likely to have droughts(干旱) than areas with more rainfall,but in any case,good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference,too.In the United States,a family of four can use 1.5tons of water a day!This shows how much we depend on water to live,but there's a lot we can do to lower the number.
You can take steps to save water in your home.To start with,use the same glass for your drinking water all day.Wash it only once a day.Run your dishwasher (洗碗機)only when it is full.Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

60.Which of the following is most likely to lead to less groundwater?C
A.Using river water.
B.Throwing batteries away.
C.paving parking lots.
D.Throwing rubbish into lakes.
61.What can be inferred from the text?B
A.All water shortages are due to human behavior.
B.It takes a lot of effort to meet our water needs.
C.There is much we can do to reduce family size.
D.The average family in America makes proper use of water.
62.The last paragraph is intended toD.
A.show us how to fix leaks at home 
B.tell us how to run a dishwasher
C.prove what drinking glass is best for us 
D.suggest what we do to save water at home
63.The text is mainly aboutD.
A.Why paving roads reduces our water 
B.how much we depend on water to live
C.why droughts occur more in dry climates
D.how human activity affects our water supply.

分析 這是一篇關(guān)于用水問題的議論文.告訴我們,盡管大量用水和污染水源使人類用水處于危險境地,但是人類一些小型的活動也對用水問題有著巨大的影響.短文詳細描寫了生活中容易造成浪費的一些用水問題,并提出了相應(yīng)的建議.

解答 60.C 細節(jié)理解題.根據(jù)第一段最后一句話"The more roads and parking lots we pave,the less water can flow into the ground to become groundwater."可知,鋪設(shè)馬路、停車場會導(dǎo)致地下水減少.故答案選C.
61.B 推理判斷題.根據(jù)第二段的"good management can help to make sure there is enough water to meet our basic needs"及下文第四段的"You can take steps to save water in your home."可知要滿足我們的用水需求需要很大的努力,故答案選B.
62.D 推理判斷題.根據(jù)該段的中心句"You can take steps to save water in your home."及本段描述,可知本段主要是針對如何節(jié)水提出建議,故答案選D.
63.D 主旨大意題.這篇文章第一段講的是"鋪設(shè)馬路、停車場會導(dǎo)致地下水減少",后三段講述了"為了滿足我們的用水需求,我們能做些什么".所有這些講的都是人類活動對地球水資源供給的影響,描述了人類活動與水資源的關(guān)系,告訴我們?nèi)绾蝸砉?jié)約用水.故答案選D---"人類活動如何影響我們的用水供應(yīng)".

點評 健康環(huán)保類文章常是介紹科學(xué)知識、生活常識和環(huán)境保護方面的短文.閱讀此類短文要以現(xiàn)象或事物為中心進行思考,理解現(xiàn)象產(chǎn)生的原因、條件和客觀規(guī)律等.同時要抓住事物的特征、用途和相互關(guān)系等.由于此類文章缺乏故事情節(jié),很多同學(xué)對此類文章感到費解.文章都是就事論事,需要邏輯推理和想象的時候較少,因此此類閱讀題也沒有同學(xué)們想象中的那么難,只要多加訓(xùn)練,就能較好地答題.

19.The average computer user has between 5 and 15 username/password combinations to log in different kinds of accounts.Some demand you use a specific number of symbols and digits,while others require you to change your password every 60 days.The feeling of confusion resulting from memorizing these login information has grown so common that it actually has a name:password fatigue(疲勞).
Having to remember so many different passwords is annoying,but it can also be dangerous.Because it is virtually impossible to remember a unique password for each of these accounts,many people leave handwritten lists of usernames and passwords on or next to their computers.
(71)GWhile these practices make it easier to remember login information,they also make it easier for thieves to hack into accounts.
Single Sign-On (SSO) confirmation and password management software can help solve this problem.With SSO,users only need to remember one password to log in to the main system.
(72)DSSO software is typically used by large companies,schools,or libraries.
(73)EIf a user loses or forgets the password required to log in to SSO software,the user will then lose access to all of the applications linked to the SSO account.Users who rely on password management software face the same problems.
Although most websites or network systems allow users to recover or change lost passwords by providing email addresses or answering a prompt(提示),this process can waste time and cause further frustration.What is more,recovering a forgotten password is only a temporary solution.
(74)A
Some computer scientists have suggested computers rely on biometrics(生物測定學(xué)).(75)F The use of biometrics raises questions concerning privacy and can also be expensive to practice.
 Software engineers and computer security experts are still searching for the cure to password fatigue.Until they find the perfect solution,however,everyone will simply have to rely on the password system currently in place.

A.It does not address the larger problem of password fatigue.
B.These software programs have been built into many major web browsers
C.The problem with password management software makes users feel powerless.
D.The SSO software then automatically logs the user in to other accounts within the system.
E.However,SSO confirmation and password management software also have drawbacks.
F.This is a method of recognizing human users based on unique traits,such as fingerprints,voice,or DNA.
G.Others solve this problem by using the same password for every account or using extremely simple passwords.

10.16-year-old Laresce Brown has become the strongest schoolgirl in the UK.She says her success is due to a joint condition,which used to engender great pain.
Laresce has six British and World Champion power-lifting records under her belt.Yet until just two years ago,a condition called hypermobility left her in so much pain that she was unable to take part in sport.Rather than letting her illness limit her life,Laresce took inspiration from her father,and began weight-lifting.This put an end to her pain,and she became a champion in her field.
Laresce loves to dance and she was a keen Morris dancer at the age of eleven.After that,she had to face daily pain in her knees,elbows and hands.She was forced to miss several days of school each month,due to pain and the lack of sleep that caused.
However,she is now effectively cured,since taking up the sport of power-lifting 18 months ago.
Laresce's position as Britain's strongest power-lifter for her age is down to her spirit and determination.To ensure her success,Laresce must train for eight hours a week."I really enjoyed the feeling of power I got and the excitement of people encouraging me to do my best.Becoming a champion was a big surprise-I just started off for fun and I was not expecting anything.So to win six titles was amazing,"she said.
Laresce's father said,"Being the father of such a high-achieving teen,I couldn't be more proud.She's truly the apple of my eye and has worked so hard to be where she is today.She's made us all so happy,and I feel we all enjoy a bright future together thanks to her."
