1.Water runs downhill from mountaintops to streams to rivers to oceans.But downhill running isn't the only way that water moves.A new study measures how water travels from country to country for human consumption.This flow isn't the type we usually think about.These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports.They call this a flow of"virtual water".
We typically think of water as the liquid that flows from a tap.However,nearly all---92percent---of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra at the university to Twente in the Netherlands.He and his team recently studied the hidden travels of virtual water used in products made from things like crops and meats.These products are shipped around the world.
Virtue water is immense.For example,consider a sugary soft drink.Hoekstra and his team estimated that to produce one half-liter of the drink requires between 170and 310liters of water.Only a tiny amount of that-about 1percent-is the water actually used in the soda.The vast majority of the water-about 95%-is used to grow and process the ingredients(原料).Another 4percent goes into the packaging and labeling,said the scientists.In Hoekstra's calculation,when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would make a large refrigerator full of water.
According to Heokstra's new report,dry countries like Israel and Kuwait,both in the Middle East,get the majority of their virtual water from other countries,through imported products.More surprisingly,a few wetter countries,like the Netherlands and the United Kingdom,also get the majority of their virtual water from other places.That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.
In the United States,most of the virtual water used comes from American sources; only about 20percent of the virtual water comes from outside national boundaries.In China,even less of the water associated with its products-about 10percent-comes from foreign countries.
Tracing the water trade,Hoekstra and his team turned up other surprising relationships.For instance,often a dry region sends virtual water to a wetter region.Dry areas in northern China,for example,send virtual water to the southern part of that country,which is wetter.
Title:Virtual water
General introduction●Water flows downhill,and also travels (66)worldwide by means of import-export trade.
●The water used in all the processes (67)involved in producing goods and food is called virtual water.
An example●Producing one half-liter of a sugary soft drink requires much water,(68)ranging from 170to 310liters.
●About 1percent of the water is used in the soda,while about 95percent is used for the (69)growth and processing of the ingredients.
●Another 4percent is used to (70)package and label the drink.
●The water used to produce and export a half-liter of soda could (71)fill a large refrigerator.
The(72)Content(s ) of Hoekstra's new report●Dry countries as well as some wet countries get most of their virtual water from foreign countries by (73)importing products.
●China and the U.S.get virtual water (74)mostly/mainly from their own sources.
●Dry regions surprisingly (75)tend to send virtual water to wetter regions.

8.Parents often believe that they have a good relationship with their teenagers.But last summer,Joanna and Henry noticed a change in their older son:suddenly he seemed to be talking far more to his friends than to his parents."The door to his room is always shut,"Joanna noted.
Tina and Mark noticed similar changes in their 14yearold daughter."She used to cuddle up(依偎) against me on the sofa and talk,"said Mark."Now we joke that she does this only when she wants something.Sometimes she wants to be treated like a little girl and sometimes like a young lady.The problem is figuring out which time is which."
Before age 11,children like to tell their parents what's on their minds."In fact,parents are first on the list,"said Michael Riera,author of Uncommon Sense for Parents with Teenagers."This completely changes during the teenage years,"Riera explained."They talk to their friends first,then maybe their teachers,and their parents last."
Parents who know what's going on in their teenagers'lives are in the best position to help them.To break down the wall of silence,parents should create chances to understand what their children want to say,and try to find ways to talk and write to them.And they must give their children a mental break,for children also need freedom,though young.Another thing parents should remember is that to be a friend,not a manager,with their children is a better way to know them.

32.‘The door to his room is always shut in the first paragraph suggests that the sonB.
A.is always busy with his studies
B.keeps himself away from his parents
C.doesn't want to be disturbed
D.begins to dislike his parents
33.What troubles Tina and Mark most is thatC.
A.their daughter isn't as lovely as before
B.they don't know what to say to their daughter
C.they can't read their daughter's mind exactly
D.their daughter talks with them only when she needs help
34.What's the meaning of"the wall of silence"in the last paragraph?B
A.Teenagers talk a lot with their friends.
B.Teenagers do not talk much with their parents.
C.Teenagers talk little about their own lives.
D.Teenagers do not want to understand their parents.
35.What can be learned from the passage?C
A.Parents are unhappy with their growing children.
B.Parents have suitable ways to talk with their teenagers.
C.Parents should try to understand their teenagers.
D.Parents should be patient with their silent teenagers.

5.The public were shocked in March when the news that improperly stored vaccines (疫苗) worth millions of dollars were sold to patients all over the country.
China is trying to rebuild public confidence in vaccines after the news struck fear into the hearts of parents.
Chief government officials should be dismissed if serious vaccine violations (違規(guī)) took place in their jurisdictions (管轄區(qū)),according to a revised regulation (規(guī)定) approved by the State Council.The regulation was passed on Saturday and took effect immediately,the report said.It strengthens management rules for vaccines,including their transportation and storage,and increases punishments for violators.
The regulation requires B-class (non-compulsory) vaccines to be given out like A-class.It also requires disease control departments,hospitals and clinics to keep records of purchases and received inventory (存貨清單).China will establish a system to track vaccines,according to the regulation.Companies and user agencies must record use,so all vaccines can be tracked across their life cycle.
China will also raise the amount of compensation paid to those suffering abnormalities (反常) after receiving vaccines.Measures under consideration include the introduction of commercial insurance to improve fairness and efficiency in compensation.Commercial insurance is expected to play an important role in compensating people for any health problems connected with vaccines.In the past,responsibility for compensation belonged to vaccine producers or to the government.
Meanwhile,local authorities are trying to reduce public worries.At Zhcheng hospital,health workers were spreading vaccine information to parents on Monday.In Northeast China's Jilin province,authorities are pioneering a digital system that makes vaccines storage transparent to the public.In Hefei,capital of Eastern Anhui province,authorities have developed a smart phone application that shares vaccine information.
Immunization (免疫) is the most economic,effective and safest way of preventing,controlling and getting rid of communicable diseases,said Mao Qun'an,spokesperson for the National Health and Family Planning Commission.Although vaccines can provide immunization against certain diseases,they can also cause side effects and result in serious physical harm in some individuals because of a person's health condition,although the chances of developing problems are extremely low,according to experts.
Vaccines stand for the primary means in most countries to prevent and control infectious diseases,and parents should get their children vaccinated as required by the government,said Yu Wenzhou,an expert at the Chinese Center for Disease Control and Prevention.

6.Some years ago on a hot summer day in South Florida a little boy decided to go for a swim in the old swimming hole behind his house.
In a hurry to dive into the cool water,he ran out the back door,leaving behind shoes,socks,and shirt as he went. (56)F His mother saw the two as they got closer and closer together in the house,looking out of the window. (57)G Hearing her voice,the little boy became alarmed and made a return to swim to his mother.It was too late.Just as he reached her,the crocodile reached him.From the shore,the mother grabbed her little boy by the arms just as the crocodile seized his legs.That began an incredible tug-of-war between the two. (58)E A farmer happened to drive by,heard her screams,raced from his truck,took aim and shot the crocodile.Remarkably,after weeks and weeks in the hospital,the little boy survived.His legs were extremely scarred by the vicious attack of the animal and,on his arms,were deep scratches where his mother's fingernails dug into his flesh in her effort to hang on to the son she loved. (59)D The boy lifted his pant legs.And then,with obvious pride,he said to the reporter."But look at my arms. (60)B I have them because my mom wouldn't let go."
You and I can identify with that little boy.We have scars,too.No,not from a crocodile,or anything quite so dramatic.But,the scars of a painful past.Some of those scars are unsightly and have caused us deep regret.But,some wounds,my friend,are because God has refused to let go.In the midst of your struggle,he's been there holding on to you.

A.I love my mother very much.
B.I have great scars on my arms,too.
C.The mother managed to pull her son from the water at last.
D.The newspaper reporter who interviewed the boy asked if he would show him his scars.
E.The crocodile was much stronger than the mother,but the mother didn't let go.
F.He flew into the water,not realizing that a crocodile was swimming toward him.
G.Dead scared,she ran toward the water,yelling to her son as loudly as she could.
