1.Could your cellphone give you cancer?Whether it could or not,some people are worrying about the possibility that phones,powerlines and wi-fi (路由器) could be responsible for a range of illnesses,from rashes to brain tumours.
For example,Camilla Rees,48,a former investment banker in the US,moved out of her apartment in San Francisco because of the radiation coming from next door.Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly."I would wake up dizzy in the morning.I'd fall to the floor.I had to leave to escape that nightmare,"she said.Since then,she's been on a campaign against low-level electromagnetic fields,or EMFs(低频电磁场).
And she's not alone.Millions of people say they suffer from headaches,depression,nausea and rashes when they're too close to cellphones or other sources of EMFs.
Although the World Health Organization has officially declared that EMFs seem to pose little threat,governments are still concerned.In fact,last April,the European Parliament called for countries to take steps to reduce exposure to EMFs.The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones.
If these fears are reasonable,then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots.
Some say there is evidence to support the growing anxieties.David Carpenter,a professor of environmental health sciences at the University at Albany,in New York,thinks there's a greater than 95% chance that power lines can cause childhood leukemia.Also there's a greater than 90% chance that cellphones can cause brain tumours.
But others believe these concerns are unreasonable paranoia (猜疑).Dr Martha Linet,the head of radiation epidemiology at the US National Cancer Institute,has looked at the same research as Carpenter but has reached a different conclusion."I don't support warning labels for cellphones,"said Linet."We don't have the evidence that there's much danger."
Studies so far suggest a weak connection between EMFs and illness-so weak that it might not exist at all.A multinational investigation of cellphones and brain cancer,in 13countries outside the US,has been underway for several years.It's funded in part by the European Union,in part by a cellphone industry group.
According to Robert Park,a professor of physics at the University of Maryland in the US,the magnetic waves aren't nearly powerful enough to break apart DNA,which is how known threats,such as UV rays and X-rays,cause cancer.
Perhaps it's just psychological.Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome,which is a condition that's considered to be psychological.
Whether EMFs are harmful or not,a break in the countryside,without the cellphone,would probably be good for all of us.
Title:Could cellphones give you cancer?

分析 本文讨论了使用手机是否会致癌的问题.一个观点是使用手机会致癌,因为有人表现出了明显症状.而另一观点是使用手机很安全.在未明白真实情况时,作者建议我们少使用手机.

解答 71.dangerous/harmful,由文章首句来看Could your cellphone give you cancer?Whether it could or no,本文讨论了使用手机是否会致癌的问题.一个观点是safe to use,则可推断另一观点是dangerous  to us,故填dangerous.
 72.possible 由第一段some people are worrying about the possibility that phones,有些人担心手机致癌的可能性,空格前有主语,故此处填形容词形式,possible
73.same  由第三段段意可知,数以百万计的人说他们会头痛、抑郁、恶心、皮疹时太靠近手机或其他来源的电磁辐射,像她一样.故此处填same.
74.connection  由倒数第四段 Studies so far suggest a weak connection between EMFs and illness-so weak,迄今的研究表明EMFs和疾病之间的弱联系很弱.故填connection.
75.destroy  由倒数第三段the magnetic waves aren't nearly powerful enough to break apart DNA,电磁波几乎没有足够强大的能力来瓦解DNA.此处填 break apart 的同义词,destroy毁坏,摧毁.
76.reasons  由倒数第二段which is a condition that's considered to be psychological,这是一种心理上的疾病.可知这是心理原因,且用复数,故填 reasons.
77.suggestions  由题右的两项措施可知这是在叙述作者对手机是否致癌问题的态度和建议.且此处应使用复数,故填suggestions.
78.concerned     由第四段governments are still concerned.可知政府依旧担心这个问题.故填concerned.
79.reduce 由最后一段a break in the countryside,without the cellphone,would probably be good for all of us,在乡下休息,没有手机,可能会对我们都好.可知作者建议我们减少使用手机的机会.故填reduce.
 80.rural 由最后一段a break in the countryside,without the cellphone,would probably be good for all of us,在乡下休息,没有手机,可能会对我们都好.故此处填乡下地区,用形容词形式 rural,乡村的.

13.Building Trust in a Relationship Again
Trust is a learned behavior that we gain from past experiences.(36)B  Trust is a risk.But you can't be successful when there's a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.
Unfortunately,we've all been victims of betrayal.Whether we've been stolen from,lied to,misled,or cheated on,there are different levels of losing trust.Sometimes people simply can't trust anymore.(37)E  It's understandable,but if you're willing to build trust in a relationship again,we have some steps you can take to get you there.
●(38)A  Having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being.
●(39)CIf you've been betrayed,you are the victim of your circumstance.But there's a difference between being a victim and living with a"victim mentality".At some point in all of our lives,we'll have our trust tested or violated.
●You didn't lose"everything".Once trust is lost,what is left?Instead of looking at the situation from this hopeless angle,look at everything you still have and be thankful for all of the good in your life.(40)G Instead,it's a healthy way to work through the experience to allow room for positive growth and forgiveness.

A.Learn to really trust yourself.
B.It is putting confidence in someone.
C.Stop regarding yourself as the victim.
D.Remember that you can expect the best in return.
E.They've been too badly hurt and they can't bear to let it happen again.
F.This knowledge carries over in their attitude toward their future relationships.
G.Seeing the positive side of things doesn't mean you're ignoring what happened.

A company by the name of Ragdoll Productions in the United Kingdom developed the Teletubbies figures and their stories.Teletubbies'producers,Anne Wood and Andrew Davenport,conducted extensive research to guarantee the effectiveness of their production as a teaching tool.(72)B The conclusions they reached were put very well into words by Ms.Wood when she said,"I want children to smile.If they are smiling,they will be relaxed.If they are relaxed,they will be confident.If they are confident,they will dare to be curious.If they are curious,they will grow in understanding."(730G Young children over the world are privileged to enjoy the benefits,for since 1992the program has been sold to 92broadcasters in 70countries.
What exactly,though,makes Teletubbies so visibly and emotionally inviting to young children?The answer is that they are completely designed from their point of view,being plump(fat and rounded in a pleasant way) and innocent-faced,as well as playful,warm,and funny. (74)A Imagine a land that is part technological and part nursery rhyme.Their home is Tubbytronic Superdome,and they eat Tubby Toast and Custard.A windmill blows in wonderful surprises among rolling hills,talking flowers,and a smiling sun.
(75)E Teletubbies love each other very much; Teletubbies love to dance and sing; Teletubbies love their favorite things and interacting with their surroundings.These messages,conveyed in very basic,repetitive language,invite interaction with children,helping ages one through four expand the skills they need to watch and listen at the same time,which is key to the development of a child's thinking abilities.

A.They live in a fascinating world that is brilliant and magical.
B.They interviewed young children,linguists,and nursery school teachers.
C.Lots of Teletubbies toys,books and DVDs are available to keep children entertained.
D.Although the program aims at children aged one to four,it appeals to older generations.
E.More importantly,the characters communicate very special,elementary ideas to the children.
F.Like other cartoon creatures,Teletubbies are colorful both in physical appearance and personality.
G.Much creative energy and innovation were channeled into each one of the 365shows that's been broadcast.
