Selfies (自拍) have become an increasingly common way to capture memorable moments. When it comes to taking selfies , knowing the following tips can directly affect the quality of your final product.

The use of light is vital to improving image quality. Lights can help avoid shadows and create soft features on your face, so turn your face toward the main light source. If you want to be creative, play with light angles by turning your body, but make sure the photo is properly exposed and your face is lit from the front or the side. Besides, avoid taking selfies against the main light source or with overhead lighting. In addition, natural light possesses a warmth that makes you look like you're glowing.(发光)

When taking selfies, angles also matter a lot. Hold the camera away from your face, and try to take photos both horizontally(水平地) and vertically(垂直地). If not, your face might look bigger than usual. Ideally, the universal selfie angle is 45 degrees above your head. But you should study your face at different angles because finding your best angle requires you having seen all of them.

One problem with selfies is that most have distracting backgrounds. You can always do more to show others your best side. Try to simplify the background by taking selfies outdoors or in spacious areas. Document yourself engaging in interesting activities---hiking with family members, visiting landmarks, or working out with friends. At least, you can make the photo appealing by getting rid of your outstretched arm or a background that's too busy.

You can also download some photo apps that allow you to adjust the lighting and contrast. Some apps offer useful filters, which can change your skin tone and remove pimples (粉刺) on your face.

1.To get an image of high quality, you need to _______.

A. be under the light source B. be against the main light

C. face the main light source D. have the photo fully exposed

2.How can you find the angle that suits you most?

A. Study your face at different angles. B. Hold the camera far enough from you.

C. Keep the camera lower than your face. D. Place the camera 45 degrees above your head.

3.Which of the following should be avoided when taking selfies?

A. The use of natural light. B. A landmark as a background.

C. Changes of the skin tone. D. A busy background.

B

The pounding(重击声) was driving Edward crazy. A new neighbor had just moved into the apartment below him. The newcomer was deaf, or seemed to be, because he played his stereo(立体声音响)loud enough for the whole building to hear.

On the first day he heard the stereo rocking over, Edward marched downstairs and politely told the newcomer that his stereo was too loud. He asked the new tenant to turn the volume down and keep it down as long as he lived in the building. The tenant appeared surprised and embarrassed, and said, “Oh, I’m sorry. I didn’t realize it was that loud.”

So, Edward returned upstairs, feeling good, because he had taken a stand and politely let the newcomer know that loud music was not going to be tolerated. The next day all was quiet, and Edward continued to be pleased with himself. The following day, Edward thought it must be Fourth of July, because a marching band was playing on his street. In fact, it was the new neighbor who was playing his music loud again.

Edward was not one to repeat himself, feeling that each time you repeated yourself, you diminished the value of your words. So, he did what he always did with rude neighbors-—grin and bear it. Eventually, they would move away. What else are you going to do?

In Los Angeles a year ago, a woman had complained to her upstairs neighbor that he was playing his drums too loud and too often. The drummer repeatedly ignored her. One day the woman walked upstairs and shot the drummer in the head and his girlfriend in the chest. The woman was sentenced to prison for 20 years.

The dead drummer won’t bother anyone with his drums, but the woman might be wishing now that she had learned to grin and bear it. If she were still living in her apartment, she could always move. When you’re in prison, you don’t have that option.

4.The man living below where Edward lived was .

A.a deaf man B.the owner of the house

C.a tenant D.an old neighbor

5.What did Edward always do with rude neighbors?

A.Grinning and bearing it. B.Persuading them to stop repeatedly.

C.Shouting them to dead. D.Moving away from the rude neighbors.

6.The woman killed her neighbor because A.he ignored her advice repeatedly B.she could not stand his playing the music too loud

C.she could not put up with him any longer D.he played the drums too often

7.The author writes the last paragraph to prove that A.being in prison means the loss of freedom B.grinning and bearing it is the best policy

C.Edward should follow the example of the woman D.the woman was right to kill her neighbor

C

Even the hardest days contain lessons that will help you be a better person.Feeling down? Consider

these things to remember when you’re having a bad day.

No one promised life would be perfect.If you look for perfection,you’ll never be content.Don’t condition your happiness on meeting every expectation you set for yourself.It is good to be ambitious,but you’ll never be perfect.If you expect otherwise,your life will be filled with disappointments.

Success doesn’t happen overnight..Don’t kid yourself into thinking success will come quickly.It isn’t easy to be patient,but anything worth doing requires time.If you get frustrated,remind yourself why your goal is important.

There is a lesson in every struggle.And once the storm is over,you won’t remember how you made it through or how you managed to survive.But one thing is certain.When you come out of the storm,you won’t be the same person who walked in.That’s what this storm’s all about.Don’t complain about how terrible your life is.If you search for the lesson in your present struggle,you’ll be able to make positive changes that would prevent similar situations in the future.

Without hard times,you wouldn’t appreciate the good ones.Strength does not come from winning.Your struggles develop your strengths.When you go through hardships and decide not to give in,that is strength.It is hard to find much to smile about when you fail,but how else would you improve yourself? If you look at failure as a part of your evolutionary process,you’ll stay positive and pursue your goals for as long as it takes.

8.Which of the following is the best title of this passage?

A.Every person has to go through hard times.

B.We can learn a lot from our struggles.

C.We should accept the fact that life is not perfect.

D.Things to remember when you are having a bad day.

9.What does the underlined sentence in Paragraph 3 mean?

A.Success will come quickly. B.Hard work leads to success.

C.Success calls for patience. D.Confidence is the first step to success.

10.We can learn from Paragraph 4 that____________.

A.1essons from struggles make us stronger B.all things are difficult before they are easy

C.we should forget how we managed to survive D.similar situations in the future will never appear

11.What can we infer from Paragraph 5?

A.Hard times make us lose heart and be short of courage.

B.Perseverance in time of hardships develops our strengths.

C.Smiles when you fail will not help to improve yourself.

D.We should try to avoid failures in the evolutionary process.

The writer Margaret Mitchell is best known for writing Gone with the Wind, first published in 1936. Her book and the movie based on it, tell a story of love and survival during the American Civil War. Visitors to the Margaret Mitchell House in Atlanta, Georgia, can go where she lived when she started composing the story and learn more about her life.

Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer’s life. She was born in Atlanta in 1900. She started writing stories when she was a child. She started working as a reporter for the Atlanta Journal newspaper in 1922. One photograph of Ms. Mitchell, called Peggy, shows her talking to a group of young college boys. She was only about one and a half meters tall. The young men

guide explains: “Now in this picture Peggy is interviewing some boys from Georgia Tech, asking them such questions as “Would you really marry a woman who works?” And today it’d be “Would you marry one who doesn’t?”

The Margaret Mitchell House is a building that once contained several apartments. Now we enter the first floor apartment where Ms. Mitchell lived with her husband, John Marsh. They made fun of the small apartment by calling it “The Dump”.

Around 1926, Margaret Mitchell had stopped working as a reporter and was at home healing after an injury. Her husband brought her books to read from the library. She read so many books that he bought her a typewriter and said it was time for her to write her own book. Our guide says Gone with the Wind became a huge success. Margaret Mitchell received the Pulitzer Prize for the book. In 1939 the film version was released. It won ten Academy Awards, including Best Picture.

12. The book Gone with the Wind was _________.

A. first published on a newspaper B. awarded ten Academy Awards

C. written in “The Dump” D. adapted from a movie

13. The underlined phrase “tower over” in Paragraph 2 is closest in meaning to_________.

A. be very pleased with B. be much taller than

C. show great respect for D. show little interest in

14. We can know about Margaret Mitchell from the passage that _________.

A. her height made her marriage unhappy B. her interest in writing continued as an adult

【2016汕头高中学业水平测试5184】

C. writing stopped her working as a reporter D. her life was full of hardship and sadness

15. Which is the best title for the passage?

A. Gone with the Wind: A Huge Success. B. Margaret Mitchell: A Great Female Writer.

C. An Introduction of the Margaret Mitchell House. D. A Trip to Know Margaret Mitchell.

Four Ways to Be a Great Roommate

Having a roommate can be one of the best experiences in college or, easily, one of the worst. Follow these tips to avoid the common mistakes that turn good roommate relationships sour.

◇Talk things out.

Communication is key. If something happens, sit down with your roommate and have a face-to-face conversation. I've seen roommate relationships fall apart because something happens and ,instead of talking to each other, the two start complaining about their roommates behind their backs.

◇Don't expect to be best friends.

Some roommates become the best of friends, and some don't. Don't put pressure on yourself or your roommate, especially when you first meet. And if your roommate doesn't end up being your best friend, don't worry.

◇ 19

This applies to food, clothes and anything else. If you want to keep a relationship going, show your roommate that you have respect for what is his or hers by asking first. Even if you both agree to share everything, you should still ask.

◇Clean up after yourself.

This should do without saying. Don't be lazy. Or, at least, don't bury your roommate in your clothes and garbage. Most people I've come across in college are messy. But being considerate with where you put your stuff will help you avoid conflict.

A.Think twice before you help your roommates out.

B. This creates nothing but awkward situations and unhappiness.

C. You don't have all the time to clean your room and keep it organized.

D. Ask before you take.

E. It all starts with you to have a good relationship with your roommate.

F. Sometimes you get stuck with someone who has tons of negative energy.

G. Remember, you're trying to make a new friend, not to scare your roommate away.

Do you want to get smarter and stay sharp? Scientists have discovered that when playing a musical instrument, the human brain can __21__ the structure as well as the __22__ of how it works.

For a long time scientists believed that the human brain was __23__ developed by age 5 and we were stuck with our gray cells for the rest of our lives. But our brain is a/an __24__ organ.

Every time you play a musical instrument, as your fingers glide over the instrument, your brain establishes important electrical __28__. As you try to figure out the right notes, you are exercising parts of the brain which are __29__ for language learning. When you __30__ your music, you are working yet other __31__ of the brain that help prevent memory loss.

The __32__ activities required for learning and playing music help to build connections in the brain between otherwise __33__ parts.

Why is this important? __34__ taking a new, unfamiliar route to school. It will take a few attempts __35__ you figure out the best shortcut to your destination. The brain works in the same way. Creating new connections can help us __36__ our brain to focus on __37__ ways of learning and storing information that is important for us.

So the next time your mother __38__ you to practice your music, you are not doing her a __39__ -- -you are __40__ strengthening and re-writing your brain for the future!
