In a shocking upset, 70-year-old Republican candidate Donald Trump rode a wave to victory as voters elected him the 45th President of the United States.

Actually, a lot of experts had predicted that Democratic candidate Hillary Clinton would come out on top. Throughout the campaign, one of Trump's main challenges was to persuade voters that he has the attitude, knowledge and judgment to be president. In the end, he was able to attract more than enough voters to his side.

Hillary Clinton admitted the election to Trump in a phone call at around 2:30 am. "Hillary has worked very long and very hard over a long period of time," Trump told his supporters during his victory speech. "We owe her a major debt of gratitude for her service to our country. "

Hillary Clinton delivered her speech later in the day. "We must accept this result and then look to the future," she told her disappointed supporters. "Donald Trump is going to be our president. We owe him an open mind and the chance to lead. "

Trump's rise to the presidency comes after a long career as a real-estate developer. He built skyscrapers, resorts and golf courses. He also risked other businesses, introducing Trump Steaks, Trump Natural Spring Water, and an airline called Trump Shuttle. In 2004, he became a TV star with the reality show The Apprentice.

Now Trump and his team will have to face many difficult things. They'll have to work to bring the country together after a divisive campaign that upset millions of Americans. Throughout the country, millions of Americans are out of work and struggling to make ends meet. The new president must also address international issues. They include the war on terrorism and the refugee crisis. Still, Trump says he sees a bright future ahead. "Every single American will have the opportunity to realize his or her fullest potential," he told his supporters.

1.What should many experts think of Trump's victory?

C. It is annoying. D. It is surprising.

Tyler was born infected with HIV and his mother was also infected. From the very beginning of his life, he was dependent on medications (药物) to enable him to survive. When he was five, he had a tube surgically(外科手术上) inserted in a vein(静脉) in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were connected to this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented oxygen to support his breathing.

Tyler wasn't willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his backpack and dragging his tank of oxygen behind him in his little wagon(小推车). All of us who knew Tyler were amazed at his pure joy in being alive and the energy it gave him. Tyler's mom often made jokes on him by telling him that he moved so fast she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.

This terrible disease eventually wore him down. He grew quite ill and, unfortunately, so did his HIV-infected mother. When it became clear that he wasn't going to survive, Tyler's mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.

A few days before his death, Tyler beckoned(召唤) me over to his hospital bed and whispered, "I might die soon. I'm not scared. When I die, please dress me in red. Mom promised she's coming to heaven, too. I'll be playing when she gets there, and I want to make sure she can find me."

1.Why did Tyler wear a backpack on his back when he was young?

A. Because his mother gave it to him as a gift.

B. Because he had no right to choose but to wear it.

C. Because he wanted to be different from the other kids.

2.Tyler asked the writer to dress him in red when he died in order to ________.

Maybe it is true that we do not know what we have got until we lose it,but it is also true that we do not know what we have been missing until it arrives.

It takes an hour to like someone,and a day to love someone,but it takes a lifetime to forget someone. Giving someone all your love is never an assurance(保证)that they will love you back. Do not expect love in return;but if it does not,be content it has grown in yours. Do not rely on one's appearance;it can trick you. Do not rely on wealth;even that fades away. Rely on someone who makes you smile,because it takes only a smile to make a dark day seem bright.

There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream;go where you want to go;be what you want to be,because you have only one life and one chance to do all the things you want to do.

The brightest future will always be based on a forgotten past. You cannot go on well in life until you let your past failures and heartaches go off. May you have enough happiness to make you sweet,enough trials(考验)to make you strong,enough sorrow to keep you human,enough hope to make you happy. The happiest people do not necessarily have the best of everything;they just make the most of everything that comes along their way. Happiness waits for those who cry,those who appreciate the importance of people who have touched their lives. Always put yourself in others' shoes. If you feel that it hurts you,it probably hurts the other person,too.

When you were born,you were crying and everyone around you was smiling. Live your life so that when you die,you are the one who is smiling and everyone around you is crying.

1.In this passage,the writer wants to tell us ______.

A. what to do in our life B. where to go with other persons

C. how to treat our life D. how to get on well with other persons

2.Which of the following statements is TRUE according to the passage?

A. If you give someone your love,you are sure to receive love in return.

B. We often don't know what we have lost until it happens someday.

C. It is wise not to rely on anybody because you are likely to be cheated.

D. If it takes you a short time to love someone,you will forget the person.

3.One should ______ the painful past according to the writer.

A. value B. remember C. consider D. forget

The demands of the modern world are growing day by day and this is putting more pressure on scientists to do research. However, as stated by Griffiths, “There is no hope of doing perfect research”. Naturally, there have been a lot of criticisms (批评), as many scientists immediately announce that their research methods are very safe and that they have the perfect research theory (理论).

However, scientific history is filled with examples, in which a perfect scientific solution that was based on decades of scientific research has been overturned (推翻) with new theories. Naturally the first example that comes to mind is the fact that Newton’s Theories were thought to be very safe and they were used in all fields of science. For centuries, thousands of scientists around the world used Newton’s Theories to formulate (规划) other theories.

However, after nearly two centuries of use, Newton’s Theories were found to be not as perfect as they were thought. Through Einstein’s publication on the General Theory of Relativity, it was found that Newton’s laws were imperfect in explaining all motions (运动) that were taking place in our universe. It was found to be imperfect under some conditions, even though, Newton’s laws are still used today to predict motion at low speeds.

Thus, perfect research is only a myth (神话). Of course, this does not mean that a scientist should simply give up and accept imperfection in his or her research efforts. Improvements and changes in research techniques and methods are a natural part of evolution (进化) and it is each scientist’s responsibility to take it forward as much as possible.

While the final answer to the universe’s questions may never exist, a time will come when there will be fewer questions as new answers are found and more improved research is carried out by scientists around the world.

1.Why have there been a lot of criticisms?

A. The modern world demands mor e and more.

B. Scientists have a negative attitude.

C. Many scientists arrive at their conclusions (结论) too fast.

D. Griffiths does not believe what scientists say.

2.Through the publication of the General Theory of Relativity, Newton’s Theories turned out to be ______.

A. not so perfect B. completely wrong C. very safe D. very exact

3.What will scientists do to deal with the “imperfectness” problem?

A. Accept the fact and give up.

B. Improve and change their methods and techniques.

C. Try their best to carry out the perfect study.

D. Ignore it and do as they please.

4.We can learn from the last paragraph that ______.

A. the universe’s questions are sure to have a final answer

B. the number of questions is sure to increase with the passing of time

C. scientists are carrying out improved studies

D. there will be more scientists in the world in the future
