9.On numbers of occasions when something goes wrong,it can be very satisfying to say,"Well,it's so-and-so's fault."or"I know I'm late,but it's not my fault; the car broke down."It is probably not your fault,but once you form the habit of blaming somebody or something else for a bad situation,you are a loser.You have no power and can do nothing that helps change the situation.However,you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation.This is the winner's key to success.
Winners are great at overcoming problems.For example,if you were late because your car broke down,maybe you need to have your car examined more regularly.Or,you might start to carry along with you useful phone numbers,so you can call for help when in need.For another example,if your colleague causes you problems on the job for lack of responsibility or ability,find ways of dealing with his irresponsibility or inability rather than simply blame the person.Ask to work with a different person,or don't rely on this person.You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about--creatively using your skills and talents so that you are successful no matter what happens.Winners don't have fewer problems in their lives; they have just as many difficult situations to face as anybody else.They are just better at seeing those problems as challenges and opportunities to develop their own talents.So,stop focusing on"whose fault it is."Once you are confident about your power over bad situations,problems are just stepping stones for success.

4.Washington:NASA has announced evidence that Jupiter's largest moon,Ganymede,has a saltwater ocean under its icy surface.The ocean seems to have more water than all the water on Earth's surface,according to new Hubble observation.
New Hubble observations of Ganymede's magnetic field strongly suggest that the moon,which is the largest in our whole solar system,is home to a subsurface ocean.
Scientists estimate the ocean is 95 kilometres thick,which is about 10 times deeper than Earth's oceans.But unlike our salty waters,Ganymede's ocean is buried under 150 kilometres of ice.
While scientists have speculated(推测) since 1970s about the presence of an ocean on Ganymede-the largest moon in our solar system-until now the only observational evidence came from a brief flyby by the Galileo spacecraft,which didn't observe the moon long enough to confirm a liquid ocean.
This discovery marks an important milestone,highlighting what only Hubble can accomplish.In its 25 years in orbit,Hubble has made many scientific discoveries in our own solar system.A deep ocean under the icy surface of Ganymede opens up further exciting possibilities for life beyond Earth.
Scientists_have_already_confirmed_the_existence_of_an_ocean_on_Europe,_another moon orbiting Jupiter,and NASA has announced plans to send an unmanned mission there searching for the life that might come with liquid water.
Hubble is a telescope that orbits Earth,but because of its impressive gravitational analyses it can be used to study the inside of far distant planets.Using these same principles,scientists could theoretically detect oceans on distant planets as well.
25.What can we learn about the Ganymede from the passage?C
A.It is a planet with the largest moon in our whole solar system.
B.It will be used by NASA as a base for the Hubble telescope.
C.Its ocean adds to people's excitement about life beyond Earth.
D.Its liquid ocean was first proved by the Galileo spacecraft.
26.Which of the following best describes the writer's attitude towards Hubble?
A
A.Favorable.B.Doubtful.
C.Negative.D.Cautious.
27.What does the underlined part in Paragraph 6 mean?B
A.An underground ocean has been found in Europe.
B.It is now certain that there is an ocean on Europe.
C.The presence of an underground ocean in Europe is not possible.
D.No evidence has shown the existence of an ocean on Europe.
28.What type of writing does this passage belong to?D
A.A term essay.
B.An exploration review.
C.An experiment report.
D.A news report..
11.Self-confidence is an attitude which allows individuals to have positive yet realistic views of themselves and their situations.Self-confident people trust their own abilities,have a general sense of control in their lives,and believe that,within reason,they will be able to do what they wish,plan,and expect.Having self-confidence does not mean that individuals will be able to do everything.Self-confident people have expectations that are realistic.Even when some of their expectations are not met,they continue to be positive and to accept themselves.
People who are not self-confident depend too much on the approval of others in order to feel good about themselves.They tend to avoid taking risks because they fear failure.They generally do not expect to be successful.They often put themselves down and tend to ignore compliments(赞美)paid to them By contrast,self-confident people are willing to risk the disapproval of others because they generally trust their own abilities.They tend to accept themselves;they don't feel they have to conform in order to be accepted.
Many factors affect the development of self-confidence.Parents'attitudes are crucial(关键性的) to children's feelings about themselves,particularly in children's early years.When parents provide acceptance,children receive a solid foundation for good feelings about themselves.If one or both parents are much to critical or demanding,or if they are overprotective and discourage children's moves toward independence,children may come to believe they are unqualified or inadequate.
Surprisingly,lack of self-confidence is not necessarily related to lack of ability.Instead it is o ften the result of focusing too much on the unrealistic expectations or standards of others,especially parents and society.Friends'influences can be as powerful or more powerful than those of parents and society in shaping feelings of one's self.Students in their college years reexamine values and develop their own identities and thus are particularly sensitive to the influence of friends.

A.the sources of self-confidence

C.th e development of self-confidence 
D.the benefits of self-confidence

B.Parents'protection prevents children's self-confidence development.
C.Parents and friends matter in building one's self-confidence.
D.College students are the least self-confident group in society.

8.Traffic Safety Tips
If you are among those who think that traffic safety tips are something that needs to be given to children and not adults,you are so very wrong.Being an adult,it is our responsibility to set a good example for others.Some of the effective traffic safety tips are mentioned below.
Put your seat belt on.
The first thing that you are supposed to do,and make sure that others in the car also do,is to put your seat belt on.Kids under the age of 12should never sit on the front seat.
(16)D
Teenagers and young adults especially,don't realize the risks they are putting themselves into.Alcohol influences your mood and mind and may not give you the judgment and control that you need to have when driving.Even smoking should be avoided and drugs should not be consumed if you are planning to drive.
Don't try to multitask.
Do you drive,listen to music,eat your sandwich and speak on the phone all at the same time?If you do this,you are not displaying your super powers but allowing different kinds of things to distract (使分心) you.Once you are driving,be it alone or with your friends and family,you are responsible for everyone present in the car.(17)E
Stay focused on the road.
Driving under pressure with your mind full of problems at work or at home would easily allow you to distract your mind off the road leading to an accident.(18)GSleep properly and stay relaxed before hitting the road.
Don't break the signal.
(19)FOr break the speed limit because you re getting late.Don't do that!The consequences for that may actually be enough to separate you from your driver's license on a permanent basis.Make sure you obey the traffic rules and guidelines and do all that you can to be a responsible citizen.
(20)C
Last but not the least,keep your car in good condition.Make sure you are giving your car for servicing and maintenance(保养) on time.Make sure you always check your car tires(轮胎) before hitting the road and don't run out of gas!

A.Be in a good mood.
B.Obey the speed limit.
C.Keep your vehicle in good condition.
D.Drinking and driving has deadly consequences.
E.So stop doing other things and focus on driving safely.
F.Your emotions or impatience may make you break the signal at times.
G.Don't let the things outside your car affect you when you are in the car.
