16.Life for Ron and Joanne Wickham used to be full of soccer games,birthday parties,school plays,and parent-teacher conferences.For most of the past 20 years,they spent their evenings reminding their children to do homework and helping them complete it.Now the evenings are empty except for TV,and the weekends seem to last forever.The children whose activities used to fill their time have moved away and have left empty spaces.The Wickham parents have what is usually called Empty-Nests Syndrome.
Ron and Joanne both work for the Heritage Insurance Company in Ukiah,California.In their mid-50s,they have two children,Anne and Josh.Anne just graduated from California State University-Fullerton and is looking for a banking job in the Bay Area.Josh is still a junior at Claremont McKenna College near Los Angeles,but he can only rarely make the 460-mile trip home to visit his parents.Back in Ukiah,Ron and Joanne often feel the house is too big."It doesn't really echo,"says Ron,"but it feels like it should.Where is everybody?"
Empty-nesters everywhere know the feeling.They are entering a new stage of life,but they remain tied to their former stage.They are typically between the ages of 48 and 60-still working,still involved in their communities,still rooted.This means they aren't free to travel for entertainment or to pull up stakes and move elsewhere.Generally,they live in the homes where they raised their children.Their daily routines may still echo their full-nest days,with wake-up times meant for driving kids to school or meals that include the children's favorite foods.Therapists point out that Empty-Nest Syndrome doesn't last forever."Eventually,a so-called empty nest starts to feel normal and new routines develop,"says UCLA psychology professor Jaswant Singh."Most parents complete this journey just fine,but it usually feels pretty lonely."

66.Which of the following statements is TRUE about Ron and Joanne?D
A.Their house is so big that it echoes when their children are not at home.
B.Their health condition doesn't allow them to eat steak and move elsewhere.
C.They can now do nothing to kill time but help Josh complete his homework.
D.Their son,a college student,occasionally travels a long distance to visit them.
67.The underlined word"This"in paragraph 3 refers toD.
A.having entered middle age                            B.their former stage
C.their community                                      D.being tied to a place
68.People with Empty-Nest SyndromeB.
A.usually feel fine when they are on a journey
B.usually lead a normal life but feel quite lonely
C.need psychologists'help to develop new routines
D.can hardly recover from it without taking medicine
69.Which of the following is the best title of the passage?C
A.Ungratefulness of Grown-up Children
B.Adjustment to Brand New Life
C.Emptiness of Empty-Nesting
D.Sacrifice Made for Children.

分析 本文属于说明文阅读,作者通过这篇文章向我们举例介绍了Ron和Joanne 这对空巢老人的生活,他们的儿女离他们都很远,只有很少的机会会回家看他们,而他们虽然过着正常的生活却觉得自己很寂寞,作者用这篇文章呼吁子女们多回家陪陪老人,不要让他们感到孤独.

解答 66.D  细节理解题,根据第二段Josh is still a junior at Claremont McKenna College near Los Angeles,but he can only rarely make the 460-mile trip home to visit his parents.可知他们的儿子在大学时偶尔会走很长的距离去看他们,因此D正确;误解分析:由第二2段Back in Ukiah,Ron and Joanne often feel the house is too big.孩子们走后他们的房子是空的,只是他们觉得自己的房子太大了,因此A错;B选项在文章中没有提及;文中没有提及他们消磨时间是帮Josh完成作业,因此C错;故选D.
67.D  理解推断题,根据第三段This means they aren't free to travel for entertainment or to pull up stakes and move elsewhere.可知这意味着他们不能自己旅行或搬到新的环境中,因此"this"指的是他们被绑在了这个地方,故选D.
68.B  细节理解题,根据第二段Back in Ukiah,Ron and Joanne often feel the house is too big."It doesn't really echo,"says Ron,"but it feels like it should.Where is everybody?"Empty-nesters everywhere know the feeling.They are entering a new stage of life,but they remain tied to their former stage.可以推断空巢老人一般过着正常的生活,但是他们会觉得很寂寞,故选B.
69.C  主旨大意题,通读全文可发现本文主要向我们介绍了空巢老人的情况,他们虽然过着正常的生活却会感觉很寂寞,故选C.

点评 考查学生的细节理解和推理判断能力.做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确选择.在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.

4."Over the years the unthinkable has become thinkable and today we sense we are close to being able to alter human heredity(遗传)."These were the words of David Baltimore of the California Institute of Technology,on December 1st,when he opened a three-day meeting in Washington to discuss the morality and use of human gene editing.Dr Baltimore is an old hand at these sorts of discussions,for he was also a participant in the Asilomar conference,in 1975,which brought scientists together to discuss a safe way of using the then-new tcchnology of recombinant DNA,and whose recommendations influenced a generation of biotechnology researchers.
Four decades on,the need for a similar sort of chin-wag has arisen.The International Summit on Human Gene Editing has been held by the national scientific academies of three countries-America,Britain and China.They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line,something Dr Baltimore described as a deep and troubling question.Like those of Asilomar,the conclusions of this meeting will not be binding.But the hope is that,again like Asilomar,a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves,rather than having politicians and civil servants do it for them.The meeting is being held against a backdrop of rapid scientific advance,Since 2012 research into a new,easy-to-use editing tool called CRISPR-Cas9 has blossomed.This technique involves a piece of RNA (a chemical messenger,which can be used to recognise a target section of DNA) and an enzyme (酶) called a nuclease that can snip unwanted genes out and paste new ones in.
Public interest was aroused in April,when Chinese scientists announced they had edited genes in non-viable ( 无活力的) human embryos,and again in November when British researchers said they had successfully treated a one-year-old girl who had leukaemia ( 白血病),using gene-edited T-cells.T-cells are part of the immune system that attack,among other things,tumour cells.The researchers altered T-cells from a healthy donor to encourage them to recognise and kill the patient's cancer,to make them immune to her leukaemia drug,and to ensure they did not attack her healthy cells.
In another recent development,a firm called Edit as Medicine,which is based in Cambridge,Massachusetts,has said it hopes,in 2017,to start human clinical trials of CRISPR-Cas9 as a treatment for a rare genetic form of blindness known as Leber congenital amaurosis (伯氏先天性黑蒙).Though other companies are already testing gene-editing therapies,these employ older,clunkier forms of the technology that seem likely to have less commercial potential.Moreover,researchers at the Broad Institute,also in Cambridge,said this week that they had made changes to CRISPR-Cas9 which greatly reduce the rate of editing errors-one of the main obstacles to the technique's medical use.
On the subject of germ-line editing,Eric Lander,the Broad's head,told the meeting it would be useful only in rare cases and said it might be a good idea to"exercise caution?before making permanent changes to the gene pool.The need for caution is advice that might also be heeded by those pursuing work in animals other than people,and in plants-subjects not being covered by the summit.
61.Which ofthe following is TRUE about CRISPR-Cas9?B
A.It has fewer side effects.
B.It can modify human gene.
B.It can protect immune system.
D.It has less commercial potential.
62.The underlined word"chin-wag"in Paragraph 2 can be replaced byA
A.discussion    B.negotiation  C.argument D.comparison
63.What can be inferred from the passage?D
A.Dr.Baltimore started his research on modiffing gene in 1975.
B.Scientists'opinions about the use of gene editing are consistent.
C.CRISPR-Cas9 has been applied to cure Leber congenital amaurosis.
D.More research should be made before the technology comes into wide use.
64.This passage is most probably aB.
A.science fiction  
B.scientific report
C.conference summary 
D.commercial advertisement.
11.You go to a store to buy food for a party.But when you get to the cash register,there are no plastic bags for the things you buy.If you live in San Francisco,this situation might not surprise you.(71)FMany cities and towns around the United States may ban plastic bags.(72)GInstead,they'd like people to use their own cloth bags when they shop.(73)DThey say they wouldn't buy as much if they couldn't get a free bag.Store owners don't want to lose business.So they want to keep offering plastic bags.
Stores should be banned from using plastic bags.Here's why:
All those plastic bags fill up garbage dumps (垃圾站).That hurts the environment.
People can use cloth bags instead.(74)AStores should not be banned from using plastic bags.Here's why:
People might buy less if stores don't offer plastic shopping bags.Some stores might go out of business.
Some people reuse plastic shopping bags for things like garbage.If they don't get them for free,they'll have to buy some.(75)CThat could get expensive.

A.These bags don't get thrown away until they've been used many times.
B.There should always be a choice.
C.If shoppers forgot a cloth bag,they would have to buy one.
D.But many people don't want to buy their own cloth bags.
E.Many people throw them away after using them.
F.That city has banned most plastic shopping bags from stores.
G.They hope that shoppers won't use paper bags either.
1.I was in Houston a few weeks ago,and needed to be back home in Austin by midmorning the next day.Though I usually left in the evening,for some reason last time I had to choose to set off after midnight.
I was on my way back to Austin when I realized I left an important file,and knew I had to return to get it.I took the first exit I could,but when I rounded the corner,an 18-wheeler was stopped dead in the exit lane.I swerved(急转弯) to avoid it,and then I realized that there was something wrong with my car.So I pulled into a small parking lot and unsurprisingly found the area deserted at 3:15am.I've lived in urban areas most of my life.I'm fairly street-wise and don't become frightened easily,but I knew I was in a pretty tough neighborhood.
There was no one in Houston to pick me up.I immediately locked the doors and picked up my phone to call a tow truck.Soon a young man knocked on my driver's side window and asked if he could help me.Judging from his appearance,he was far from a mad man,but I knew he was far more likely to rob than help me.So I lied to him.After a while,he asked again,but this time I politely refused and told him the tow truck was due any minute.He finally said,"Madam,you need help.A tow truck in Houston will arrive anywhere between 45minutes and approximately never (which I knew was true),and you aren't going anywhere until you change your flat tire."
After considering thoroughly,I got out.He looked surprised,but got right to work.He changed the tire,returned the seat to its place and said,"Thank you for letting me help you.You gave me a chance when most people would never open the door to someone like me.Would it be okay if I gave you a hug?"When I recovered,I gave him a giant hug.I left with a new tire and a renewed faith in human nature.
