19.A pioneer who made poor lands bloom is the winner of this year's World Food Prize.Daniel Hillel developed drip irrigation(滴灌) techniques that squeeze the most crop out of a drop of water,making farming possible in places where water is scarce(缺少).
Farmers now rely on it in water-scarce regions from Spanish vineyards,to African onion fields,to America's fruit and salad bowl."Wein California grow about 50percent of the fruits and vegetables of the continental United States,"says University of California at Davis hydrologist Jan Hopmans."And the reason that is possible is because of,indeed,these drip and micro-irrigation techniques."
Hillel got his start in dryland farming as a pioneer in Israel's Negev Desert in the 1950s."The issue was efficient use of water,"he says,"because land is available.It's extensive.Water is limited."These desert farmers did not have the luxury of running irrigation water through channels to their crops,the way farmers have since ancient times.So Hillel and others gave plants just what they needed,just where they needed it.
"The idea was to apply the water little by little,the way you spoon-feed a baby,"Hillel says.It worked so well that Hillel was soon traveling the world,showing others how to do it.Experts say drip irrigation is an innovation whose importance is growing,as climate change and rising population strain(使…緊張) water supplies in many parts of the world.
"This is where water use,water availability,water-use efficiency and climate change and crop production all converge,"Hillel says."And this has been really the essence of my career."
A career whose legacy(遺產(chǎn)) can be measured drop by drop.

B.Daniel Hillel is becoming more popular worldwide.

7.A family has been defined as a couple and their children,sharing a common house and dividing the work by gender.In general,the woman has to be at home,ooking after her children,while the man works outside the home.In fact,in 2014,only 15percent of all American families resembled the so-called typical American family.
Nuclear Family(The Formal Type!)
A nuclear family is considered to be the most traditional family,consisting of a mother,a father,and the children.This family type holds a lot of respect by society,known as the ideal one to raise children.It is believed that children belonging to the two-parent structure families are stable.However,with changing times,it has been observed that the nuclear structure has become less popular.
Single Parent Family (Mostly the Breadwinner Parent!)
A single parent is the one who looks after the child without the assistance of the other parent.The child can be by birth or adoption.Single parent families are often the result of death of another parent,divorce of a couple with children,or child abuse.There's another case where adults who want children but do not have a partner,adopt kids-usually termed as single parent adoption.
Grandparent-led Family (The Wrinkled Affection!)
Lots of grandparents are raising their grandcildren today.Reasons can be varied,like parents'death,or unfit parents.Many grandparents need to go back totheir working phase for finding a source of income to raise their grandchildren.
Blended (混合的) and Step Family (Sometimes the Black Sheep Type!)
Two separate families blending together to form a single unit can lead to the creation of a blended or step family.Step families are becoming common in America.Over half of the marriages end in divorce,and many of these individuals prefer getting remarried,thereby creating the step family.It can consist of a new husband,a wife,and their children from preious relationships or marriages.These families have more problems because their kids do not get comfortable,and have adjustment and discipline issues.
Extended Family (The More,The Merrier!)
An extended family is the one that enlarges beyond the immediate family,which can consist of grandparents,uncles,aunts,cousins and so on,living under a single roof.There are certain advantages to such family groups.The members (especially children) feel more secure and safe due to elder guidance and sharing of resources during a crisis,and have more role models to help maintain desired etiquette and values.
Childless Family (Child-free Companions!)
While most people think of family as including children,there are couples who are very young and intend to have children later,or those who cannot,or choose not to have children.This type is also called the"forgotten family",as it does not meet the set in definition of family.It has been observed that many of the childless families own pets or have external contacts with their nieces and nephews as a substitute for having their own children.
As you can see,there are various family structures.The American society tends to promote the traditional family through various media; children who fall under other categories may feel that theirs is not a real family.They may get self-conscious about being part of a family which is"different".In some cases,they might face social challenges,too.
25.All of the following may contribute to a single parent family EXCEPTB.
A.a(chǎn) broken marriage
B.a(chǎn) bad-tempered parent
C.the death of one parent
D.a(chǎn) single adult adopting a child
26.According to the passage,in grandparent-led families,D.
A.the children gain more respect from society
B.the children face more challenges in society
C.the"parents"give more guidance to children
D.the"parents"have to work again to raise children
27.What kind of family is most likely to keep a pet?C
A.A nuclear family.
B.An extended family.
C.A childless family.
D.A step family.
28.What might be the best title for the passage?B
A.Life in a typical American family
B.Types of family structures in America
C.Family structures matter a lot in America
D.Different families have different values and needs.

14.Your manager comes to you in a panic and asks you to take the place of Sharon,who will be out of town all next week.Your first thought is,"Why me?"Although you are not so happy,you smile and say,"No problem."Your boss is making t he request,after all,so refusal is not a choice.Right?
Not necessarily.In some cases,"Sorry,I can't"may be the most proper response.Here are two examples of situations in which it might make sense to say no and suggestions for how to turn down the boss.
"It seems that Joe can't make the deadline again.Can you handle it?"
The solution(解決方法):If your boss does need your help,taking on the extra work is the right thing to do and can earn you valuable bonus points.However,if these situations arise regularly,to the point where they begin to interfere (干擾) with your regular work,you may need to start pushing back.Next time your boss approaches you seeking emergency help,you might say,"Of course I'll help.But,as you know,I've had to cover for others a lot lately,and it's affecting my own work.Once we get through this project,can we talk about how to better get used to these types of requests in the future?"
"Sorry,but you have to work late again tonight.OK?"
The solution:Most employees understand that there are times when they must stay late to finish their work.But when these requests become frequent,you should speak up.Putting in extra hours every day can quickly lead to breakdown.
Therefore,you might say to your manager,"We're all working a lot of extra time lately.And these hours are becoming difficult for me to maintain(維持).Will we need to keep this pace much longer?If so,could we talk about ways that might help me achieve a better work/life balance during this period?"
It's never easy to say no to your boss.But in some situations it's necessary.Even the best managers can fail to recognize when they're asking too much of their employees.Yes,sometimes you must give in when asked to do something you don't like.But that doesn't mean you must agree to unreasonable requests without question.
24.Which of the following is the best title?A
A.How to Say No to Your Boss                   
B.How to Deal With the Mean Boss
C.How to Respond to Unreasonable Requests      
D.How to Refuse to Stay late
25.Which of the following is true of Joe?D
A.Joe is in hospital.
B.Joe is late for work.
C.Joe will have a week off next week.
D.Joe probably can't finish work on time.
26.What is the writer's attitude towards working overtime frequently?D
A.Positive.B.Negative.C.Unconcerned.D.Objective.
27.According to the passage,turning down your boss isA.
A.difficult        B.pleasant       C.simple          D.easy.

4.Life comes in  package.This package includes happiness and sorrow,failure and success,hope and despair.Life is a learning process.Experiences in life teach us new lessons and make us a better person.With each passing day we learn to handle various situations.
Love
Love plays a pivotal role on out life.Love makes you feel wanted.Without love a person could go hayward and also become cruel and ferocious.In the early stage of our life,our parents are the ones who shower us with unconditional love and care,they teach us about what is right and wrong,good and bad.But we always tend to take this for granted.It is only after marriage and having kids that a person understands and becomes sensitive to others feelings.Kids make a person responsible and mature and help us to understand life better.
Happiness and sorrow
Materialistic happiness is short-lived,but happiness achieved by bringing a smile on others face gives a certain level of fulfillment.Peace of mind is the main link to happiness.No mind is happy without peace.We realize the true worth of happiness when we are in sorrow.Sorrow is basically due to death of a loved one,failure and despair.But these things are temporary and pass away.
Failure and success
Failure is the path to success.It helps us to touch the sky,teaches us to survive and shows us a specific way.Success brings in money,fame,pride and self-respect.Here it becomes very important to keep our head on out shoulder.The only way to show our gratitude to god for bestowing success on us is by being humble,modest,courteous and respectful to the less fortunate ones.
Hope and despair
Hope is what keeps life going.Parents always hope their children will do well.Hope makes us dream.Hope builds in patience.Life teaches us not to despair even in the darkest hour,because after every night there is a day.Nothing remains the same we have only one choice keep moving on in life and be hopeful.Life teaches us not to regret over yesterday,for it has passed and is beyond our control.Tomorrow is unknown,for it could either be bright or dull.So the only alternative s work hard today,so that we will enjoy a better tomorrow.

44.In which section can readers probably read the passage?C
A.Opinions.
B.Politics.
C.Education.
D.Lifestyles.
45.How is the passage organized?C
A.In order of rules.
B.In order of frequency.
C.By making comparison.
D.In order of importance.
46.What's the general meaning of the last sentence of the whole passage?A
A.If you work hard,you'll have a better life in the future.
B.When choosing between"today"and"tomorrow",you'd better enjoy tomorrow.
C.What you only can choose is to work hard today rather than tomorrow.
D.Enjoying a better tomorrow is your only choice.
47.What's the purpose of the passage?D
A.To encourage people to love each other.
B.To tell people how to deal with happiness and sorrow.
C.To remind people of keeping having a beautiful dream.
D.To give readers some information about life.
