17.Among all the fast growing science and technology,the research of human genes(61)orbiological engineering as people call it,is drawing more and more attention now.sometimes it is a hot topic(62)discussed(discuss) by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with,such as canner and heart disease.Every year,millions of people are murdered by these two (63)killers(kill).And to date,doctors have not found (64)aneffective way to cure them.But  if the gene technology(65)is applied_( apply ),not only these two disease can be cured completely,(66)bringing (bring ) happiness and more living days to the patients,but also the great of money people spend on curing their disease can be saved,so (67)it benefits the economy as well.In addition,human life span can be prolonged.
Gene technology can help people to give birth to more healthy and clever children.Some families,with the English imperial(皇室) family being a good example,have hereditary disease.This means their children will for sure have the family disease,(68)which is a great trouble for these families.In the past,doctors could do nothing about hereditary disease,(69)But gene technology can solve this problem (70)perfectly( perfect ).The scientist just needs to find the wrong gene and correct it,and a healthy child will be born.

分析 本文介绍了基因技术,详细讲述了基因技术的好处.

解答 61.or 考查连接词.根据句意 human genes和biological engineering 表示同一个概念,故用or表示选择关系.
62.discussed 考查非谓语.此处discussed是过去分词形式,修饰topic表示被动,意思是被人们讨论的热门话题.
63.killers 考查名词.前面提到canner and heart disease癌症和心脏病,这是两大杀手.
64.an  考查冠词.way为可数名词,意思是方法,故前用不定冠词修饰,表示一种有效的方法.
65.is applied  考查被动语态.根据句意可知,基因技术和apply应用之间是被动关系.
66.bringing 考查分词.此处bringing是现在分词做状语,表示结果,结果给病人带来了幸福.
67.it  考查代词.此处it代指前文出现的the gene technology.
68.which 考查连接词.分析句式可知,此处是一个非限制性定语从句,缺少主语,故用which.
69.But 考查连接词.根据前句In the past,doctors could do nothing about hereditary disease在过去,医生没有办法治疗这种病,但是基因技术可以解决,两句之间是转折关系.
70.perfectly 考查副词.此处修饰动词 solve this problem 需用 用副词形式.

7.At first,the earth's surface layer (层) was made up of huge blocks of hard,solid rocks.Then slowly,the rocks broke up into smaller and smaller pieces.Finally stones,pebbles (卵石) and grains of sand were formed.Many sorts of plants and animals lived and died on the surface of the earth.Their remains mixed up with the stones,pebbles and formed soil.The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones.Wind,water,heat and cold help to break up rocks.When winds blow grains of sand against a large rock for a long time,the softer layers of the rock are slowly worn away.These leave holes and cracks in the rock,which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also helps to break up rocks.As the water moves along,it carries with it small pieces of rock.These rub the larger ones.Thus,the larger rocks are worn down to smaller pieces.
The heat of the sun is also helpful to breaking up rocks.When the sun shines,the rocks become very hot.If these rocks are suddenly cooled,they may crack.Ice also plays a part in making soil.Water in the cracks can turn into ice in cold weather.As this happens,it becomes bigger and the cracks become wider,and finally break into smaller pieces.

5.Roughly half of college students will have some degree of depression at some point during their time in school.Even more startling 6.2percent of college students surveyed in 2012considered suicide and 1.3percent attempted it,according to an American College Health Association study released this spring.If you're feeling depressed on campus,you may find the following tips helpful.
Exercise:Physical activity releases endorphins-chemicals that produce an overall positive feeling within the body,which fight depression naturally.Mental health experts claim that exercise is a solution to those feeling mild or moderate depression.However,for those severely depressed,simply doing sports is not enough.
Use school counseling services:Campuses don't employ mental health experts simply to throw thousands of dollars down the drain.Their job is to help students,so experts recommend you use them.Most students,however,are hesitant to take a trip to their college's counseling center,fearing being laughed at by peers.As a result,some schools like Texas Christian University,are testing students for mental health problems when they get sick and visit the campus health clinic.
Take advantage of technology:Staying in touch with family members and friends from childhood and high school has become easier than ever with the coming of Facebook and video chat services like Skype.While mental health experts insist that it's important to make friends in your new environment and be involved in the college community,it's also significant to keep in touch with the people you knew before college.
Go to sleep:Following a fairly regular sleep pattern can defend you against depression.In college,many students'sleep patterns are irregular thanks to late-night studying and partying,which is harmful to their mental health.Research strongly suggests that sleep is the key to learning and memory formation.

24.According to the passage,physical activityB.
A.is regarded as the best way to fight depression
B.contributes to the release of endorphins
C.can't help the seriously depressed students
D.improve people's ability to learn and memorize
25.It can be inferred from the 3rd paragraph thatC.
A.employing mental health experts on campus is a waste of money
B.students with mental health problems can't get on well with others
C.going to college's counseling center for help requires a lot of courage
D.sick students in Texas Christian University must take psychological tests
26.Taking advantage of technology is encouraged because itB.
A.enables students to get involved in college life
B.helps students stay in contact with others
C.offers students a way to make new friends
D.provides a way to avoid getting bored
27.Which of the following can NOT help one reduce depression?D
A.Taking exercise regularly every week.
B.Chatting with old friends with Skype.
C.Turning to mental health experts for advice.
D.Holding parties deep into the night to relax.
9.More People Are Leaving the Rat Race for the Simple LifeTime is more precious than money for an increasing number of people who are choosing to live more with less-and liking it.
Kay and Charles Giddens,two lawyers,sold their home to start a B&B hotel.Four years later,the couple dishes out banana pancake breakfast,cleans toilets and serves homemade chocolate chip cookies to guests in a B&B hotel surrounded by trees on a hill known for colorful sunsets.
"Do I miss the freeways?Do I miss the traffic?Do I miss the stress?No,"says Ms.Giddens,"This is a phenomenon that's fairly wide spread.A lot of people are reevaluating their lives and figuring out what they want to do.If their base is being damaged,what's the payoff?"
Simple living ranges from cutting down on weeknight activities to sharing housing,living closer to work,avoiding shopping malls,borrowing books from the library instead of buying them,and taking a cut in pay to work at a more pleasurable job.
Vicki Robin,a writer,lives on a budget equal to a fifth of what she used to make."You become conscious about where your money is going and how valuable it is,"Ms.Robin says,"You tend not to use things up.You cook at home rather than eat out…"
Janet Luhrs,a lawyer,quit her job after giving birth and leaving her daughter with a nanny for two weeks."It was not the way I wanted to raise my kids,"she says,"Simplicity is not just about saving money; it's about me sitting down every night with my kids to a candlelit dinner with classical music."
Mrs.Luhrs now edits a magazine,Simple Living,which publishes tips on how to buy recycled furniture and shoes,organize potluck dinners instead of expensive receptions,and generally how to consume less.
"It's not about poverty,"Mrs.Luhrs explains,"It's about conscious living and creating the life you want.The less stuff you buy,the less money goes out of the door,and the less money you have to earn."

6.The well-known adventurer and explorer Steve Fossett was famous for extraordinary efforts in setting world records in flying,ballooning and sailing.He set or broke over 100records in five different sports.Many of these records still hold.
Steve Fossett was born in 1944in Jackson,Tennessee.At twelve,he climbed his first mountain,and he kept going by choosing bigger and bigger goals.During his life,Fossett climbed the highest mountain on every continent except Mount Everest.
Also in 1985,he became the 270th person to swim across the English Channel.In 1991Fossett decided to pursue the highest goals in ballooning and sailing.Steve Fossett attempted the hot-air balloon trip around the world six times.This was not easy to do.During his fourth attempt in 1998,he was almost killed during a thunderstorm off the coast of Australia.Fossett successfully made the trip in 2002.He traveled over 33,000kilometers for over 14days.On this fight,Fosstt set other records including a speed record of 322kilometers per hour.
Many of Steve Fossett's most extraordinary adventures were as a pilot.In 2005,he became the first person to fly a plane alone around the world without stopping for fuel.In 2006,Fossett and another pilot set an altitude record for flying a glider(滑翔机),a plane with no engine.They flew the glider into the Earth's stratosphere(平流层) at a height of over 15,000meters.
Steve Fossett once said that he did not like risks.He knew this might sound strange considering his activities.But he said what he tried to do was reduce risk with careful planning,technological development and the help of the best scientists and other experts.
Yet,no amount of planning can prevent the possibility of risk in life.In September of 2007,during a short-distance flight,his plane disappeared.At last,in February of 2008,a judge in Chicago declared Steve Fossett legally dead.He was sixty-three years old.
24.Which shows the correct order of the following events?B
a.Steve Fossett climbed his first mountain.
b.Steve Fossett made the hot-air balloon trip around the world successfully.
c.Steve Fossett became the 270th person to swim across the English Channel.
