3.When I was 16 years old and in foster care (非亲代养)in Tennessee,people told me I was unadoptable.But I desperately wanted a family.I sought the help of a judge,even the commissioner of the Department of Children's Services,and was adopted just a week before my 18th birthday.
    We have a lot to be grateful for and this holiday season let's not forget about the more than 415,000 youth in foster care especially older youth.These youth are the most likely to get overlooked for adoption,but they shouldn't be.They need and deser ve a family just as much as young children do.Making an older youth a part of your family can bring just as much a joy as adopting a baby or a younger child-without all the diapers and potty training.
My adoption was life changing and probably the best thing that ever happened to me.I still remember the first gift my parents gave to me.It was a Mickey Mouse key chain with a key to their home.They told me that no matter what happened they would always love me and I'd always have a place to come home to.This is our 17th Thanksgiving together…
    My first Thanksgiving with my family was a little overwhelming with lots of extended family including grandparents,aunts,uncles,and cousins.However,it's when I realized that I would never have to spend another holiday alone and that was truly an amazing feeling.
    I was always eager to spend time with my little sister,Beth.She was six when I joined the family.My dad always says he knew we were really sisters,and I was no longer a guest in the house when Beth and I had our first fight.Today,she's one of my best friends,and I'm her b iggest cheerleader.
    There were also bittersweet Thanksgivings.One we spent in my mom's hospital room.It was there that she helped me plan my wedding but passed away three weeks before the ceremony.My dad walked me down the aisle,and my sister was my maid of honor.Because of our bond,we were able to support each other through that challenging time and that's what family is for-the good and bad times.
    It's nice having my dad and sister to share holidays and special occasions.But they're even more important when it comes to the little things-like having someone to share my bad day with,celebrate my promotion at work,or help me think through a difficult decision.It's in these moments that I just can't imagine being alone in the world.
    I'm so glad that I didn't listen to those people who said I was unadoptable,I'd never find a family,and that I was putting myself out there for rejection.It's a risk for older foster youth to consider adoption.It's an opportunity to be rejected once again. But it's a risk they should take because life doesn't end at 18.It's really just beginning.
    If you know someone who might consider adopting an older teen,please share my story--and have him or her think of my family.They didn't get to see my first steps or watch me be a pilgrim in my second grade Thanksgiving play.But they taught me so many things about life,and were there to watch me walk across the stage when I graduated from college and law school and accompanied me to the White House last year as I was honored for my work helping foster youth.
    I look forward to many more Thanksgivings with my family,and I'm eternally thankful they chose me to be a part of their family.

2.When we analyze the salt salinity (盐浓度) of ocean waters,we find that it varies only slightly from place to place.Nevertheless,some of these small changes are important.There are three basic processes that cause a change in oceanic salinity.One of these is the subtraction (减少) of water from the ocean by means of evaporation (蒸发).In this manner,the salinity is increased,since the salt stays behind.If this is carried to the extreme,of course,white salt would be left behind; this,by the way,is how much of the table salt we use is actually obtained.
The opposite of evaporation is precipitation,such as rain,by which water is added to the ocean.Here the ocean is being diluted (稀释) so that the salinity is decreased.This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean.Thus salinity may be increased by the subtraction of water by evaporation,or decreased by the addition of fresh water by precipitation.
Normally,in hot regions where the sun is very strong,the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation.Similarly,in coastal regions where rivers dilute the sea,salinity is somewhat lower than in other oceanic areas.
A third process by which salinity may be altered is associated with the formation and melting of sea ice.When seawater is frozen,the dissolved materials are left behind.In this manner,seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared.Of course,when this ice melts,it will tend to decrease the salinity of the surrounding water.
In the Weddell Sea,the densest water in the ocean is formed as a result of this freezing process,which increases the salinity of cold water.This heavy water sinks and is found in the deeper portion of the oceans of the world.

1.Surgical teams accidentally leave clamps,sponges and other tools inside about 1,500 patients nationwide each year.
  The mistakes largely result not from surgeon tiredness,but from the stress arising from emergencies or complications(并发症) discovered on the operating table,the researchers reported.
  The study found that emergency operations are nine times more likely to lead to such mistakes,and operating-room complications requiring a change in procedure are four times more likely.
  It also happens more often to fat patients,simply because there is more room inside them to lose equipment,according to the study.
Two-thirds of the mistakes happened even though the equipment was counted before and after the procedure,in keeping with the standard practice.
Most lost objects were sponges,but also included were metal clamps and electrodes(电极).In two cases,11-inch retractors (牵引器) metal strips were forgotten inside patients.In another operation,four sponges were left inside someone.When there is significant bleeding and a sponge is placed in a patient,it can sometimes look indistinguishable from the tissue around it.
  The lost objects usually lay around the abdomen (腹腔) or hips but sometimes in the chest.They often caused tears or infections.Most patients needed additional surgery to remove the object.In other cases,patients even sensed nothing about the object,and it turned up in later surgery for other problems.
  To prevent such mistakes from happening,Loyola University Medical Center is becoming one of the first hospitals in the country to use sponges outfitted with bar codes.The new system was brought to Loyola through the efforts of the hospital's operating room nurses.
  Another effective way is to X-ray patients after surgery to reduce the likelihood of objects being left inside patients.
56.In which of the following situations are objects most likely to be left inside a patient?C
A.The nurses are counting the equipment and the patient is being X-rayed.
B.The surgeons are doing the last operation of the day,and everyone is exhausted.
C.unexpected happens and some changes must be made in the procedure.
D.A complex operation is going on according to the plan made by many experts.
57.Which of the following statements is NOT true?B
A.Such mistakes happen more often to fat patients.
B.1,500 patients suffer from the mistake all over the world every year.
C.X-ray examination can help to find the lost objects.
D.The mistake largely results from stress rather than tiredness.
58.What can we infer from the passage?B
A.Surgical teams aren't to blame for the mistakes.
B.Some people never know there is something left inside their body.
C.Most mistakes happen because equipment isn't counted after the procedure.
D.Only some small objects may be left inside the patients.
59.What is the best title for the passage?B
A.Never Trust Anyone                  
B.A Mistake in the Operating Room 
C.Carelessness and Mistakes               
D.Tips for Patient Safety.
