【題目】 A little battery puts out a little bit of electricity, so you can use it safely for your experiments. But the electricity that comes through the wires in your house or school is much more powerful. 【1】 .

Inside the walls where you live or study, there are big wires that carry electricity. When you plug in a light or radio or other electrical appliance, you are putting the light or radio in the path way of the electricity. You have heard adults warn, “ 【2】，‘ Now do you know why? If you did, you would become part of the electrical path way.

【3】 The electrical current coming through the wires to the wall plug is so strong that it would hurt a lot if you stuck your finger in the plug. Put your finger in there and it could be you, rather than the light bulb, that becomes part of the electrical path way. And that would hurt!

What if you held a piece of metal, like a fork or knife, and stuck it into the wall plug? Don't do it. Why? It's because metals also conduct electricity. 【4】

Don't touch any electrical appliance when you are wet. Can you think why? It's because water is a good conductor of electricity. When your hands are wet or when your body is in a bathtub full of water, the electricity could flow right through you and give you an awful shock, or even kill you.

Electricity is very useful, but it can be dangerous. 【5】If so, electricity can better serve you, instead of hurting you.

A.Life is precious!

B.So stay away from wires.

C.Be careful, be safe and be smart.

D.And you would get a terrible shock!

E.Don't stick your finger into the wall plug.

F.Therefore, keep in mind some safety rules.

G.Your body is a pretty good conductor of electricity.

【答案】

【1】F

【2】E

【題目】 Recently, as I watched my son Nathan play basketball for his high school team, I started to feel sorry for myself and for him. His team was facing adversity (逆境) — it was the opponent’s home gym filled with their supporters, and Nathan’s team was left behind for three quarters of the game.

As for me, I had been fired earlier in the day. I was prepared for it as I had experienced the same thing 14 years earlier, but, just like a punch in the mouth, the blow is never softened because you were expecting it.

As I watched the adversity on the court that my son was experiencing, I recalled my earlier events, packing up everything in a box and waving goodbye to a great group of colleagues with whom I’d had the pleasure of working. During my driving home, I kept telling myself “Just like that time, I will find work again in a short time—I am confident in my experience and abilities.” It was the same belief that I tried to teach my son.

The basketball game entered the fourth quarter with Nathan’s team still trailing. As Nathan and his teammates fought back, I saw the focus and determination on him, as well as his teammates’faces. Then, with a tie game and seconds on the clock, Nathan found himself with the ball. There was no room for self-doubt. With skill and confidence he was able to tune out all that could drive his attention away and make the throw as if he had done it a thousand times. The joy on his face, the cheering from the crowd, and the silence on the other side of the gym—it was a moment that would make any parent proud.

As I sat there, my heart bursting with pride, it dawned on me that I had taught him determination in the face of adversity, and he had just taught me the same lesson. That brief moment of self-doubt and feeling sorry for myself was blown away by the actions of my son on the basketball court. He will play in the finals, but it doesn’t matter if he wins or loses, at this moment.

【1】What did the author intend to show by mentioning his experience 14 years ago?

A.He quit a job again.B.He disliked working with the colleagues.

C.He made a right career choice.D.He had confidence in his abilities.

【2】What can we infer from the passage?

A.Nathan’s teammates couldn’t focus on the play.

B.The author was never worried about his son’s team.

C.Nathan’s team lost the game at last.

D.The game was in a tie at one time.

【3】What is the passage mainly about?

A.A blow from losing a job.B.A lesson on the court.

C.The importance of teamwork.D.The rise and fall of a game.

【題目】請(qǐng)認(rèn)真閱讀下列短文，并根據(jù)所讀內(nèi)容在文章后表格中的空格里填入一個(gè)最恰當(dāng)?shù)膯卧~。注意：每個(gè)空格只填1個(gè)單詞。請(qǐng)將答案寫在答題卡上相應(yīng)題號(hào)的橫線上。

Potential energy is the energy, chemical or physical, stored within an object, atom or molecule（分子）. Think about a car at the top of a roller-coaster （過山車）, pausing just before it slopes into the next turn. A log resting in a fireplace just before it is about to be lit is a treasure house of potential energy. As the log burns, the connections between carbon atoms that make up the wood are being broken down, and the potential energy stored within those connections is being released as heat and light. As a comet approaches a planet or star, it slows, momentarily affected by the larger body’s gravity. The potential energy builds up and then reaches a breaking point as the comet accelerates around the larger body, and is shot out to the other side.

Sports show countless examples every day of potential energy being transformed into kinetic energy. Kinetic energy is the energy of movement. When an archer（弓箭手）draws and holds her arrow, her bow is filled with stored potential energy. When she releases the bowstring, all the potential energy is quickly transformed into kinetic energy, which is transferred to the arrow that takes flight.

The transformation of stored potential energy into kinetic energy can also be made use of to power homes, factories and entire cities. The most notable example is the Hoover Dam. The Hoover Dam is an arch-gravity dam by design. This design name is the first clue as to how exactly the dam makes use of energy. Located in the Black Canyon of the Colorado River, the Hoover Dam formed, and now holds back Lake Mead — the largest reservoir in the United States.

Gravity acts as a force upon Lake Mead. Held at bay by the Hoover Dam, the waters of Lake Mead and the Colorado River gain greater potential energy with each passing moment. The Arizona and Nevada spillways（溢洪道）are two means by which the waters of Lake Mead can escape the dam. As the lake water falls over the walls into a spillway, potential energy is instantly transformed into kinetic energy. The channels through which the water normally escapes every day are the four intake towers. These towers allow the water flow through passageways to the powerhouse and hydroelectric generators. When the water reaches the intake towers and is allowed to flow down through the passageways, all the stored potential energy created by the force of gravity acting upon the water is transformed into kinetic energy, just as when water flows over the wall into a spillway. By taking advantage of the transformed potential energy of Lake Mead, the Hoover Dam provides power to California, Nevada and Arizona.

Moments like these happen all across the physical world, whether on the molecular or universe level.

Main points

Supporting details

What is potential energy?

Potential energy is the energy existing either in the chemical or physical 【1】, which is stored in an object.

When a car is sloping into the next turn from the top of a roller-coaster, it is building up potential energy.

When a log is burning, the connections between carbon atoms are being broken down, 【2】 potential energy as light and heat.

When a comet approaches a planet or star, the potential energy 【3】 to a breaking point and then the comet is shot out to the other side.

How is potential energy transformed into kinetic energy?

Potential energy can be transformed into kinetic energy, which is the energy【4】 by movement.

When the bowstring is released by an archer, the potential energy stored in the full bow is quickly transferred to the arrow, thus transformed into kinetic energy which sets the arrow 【5】 far away.

Hoover Dam is the most notable example of energy transformation.

Hoover Dam is 【6】 in the Black Canyon of the Colorado River, holding back Lake Mead.

The waters of Lake Mead escape the Dam, falling over the walls into Arizona and Nevada spillways, leading to the 【7】 transformation from potential energy into kinetic energy.

The 【8】 of potential energy is from the force of gravity acting upon the water

What 【9】 is the energy transformation made of?

Homes, factories and cities are efficiently 【10】 thanks to the powerhouses and hydroelectric generators taking advantage of the transformed potential energy.

【題目】 The boy sat on his chair, with his hands above the keyboard. He thought about what to write.

He recalled that the competition deadline was merely a week away. But he still had not even started on his piece. He looked at the brochure again.“WRITING COMPETITION！” the title read. His mom had encouraged him to enter the writing competition, and now he was taking it on as his personal task for the holidays.

As the boy reflected on his previous writing efforts, he realized how hopeless his task of winning was. Every story he ever wrote was based on other stories. He had little imagination, and unfortunately, imagination was the key to writing.

Suddenly, he had a brainwave. This time, he came up with an original and imaginative story.

The words shot towards him like a storm of leaves. Words were coming easily, flowing through him, faster than he could type. He typed faster than he ever had before. He continued to type, amazed how easy writing this story was. The boy could not stop writing. He looked at the word count and saw the number “248” staring right back at him. He was not even halfway yet.

Then he heard his mother’s call of saying time for bed. He continued writing the piece, ignoring her. He had to make up for the time he had lost in thinking about a topic to write.

Finally, he finished. The word count now read “498”.

“Perfect，” he thought, “just under the word limit.” He knew this was the story that would win.

He went to the website and searched for the competition. He found the page but there was no “Enter” button.

Confused, he then reread the page again. It read COMPETITION CLOSED.

【1】What caused the boy to take part in the writing competition?

A.A new computer.

B.The prize money.

C.His own interest.

D.His mom’s encouragement.

【2】How did the boy finish his earlier writing?

A.His mom helped him.

B.He copied others’ ideas.

C.His friends assisted him.

D.He used his imagination.

【3】Why did the boy delay his writing?

A.Because he was terribly lazy.

B.Because he didn’t know what to write.

C.Because he wasn’t confident.

D.Because he read too many stories.

【4】Which might be the maximum word limit for each entry?

A.100.B.250.

C.500.D.1000.

【題目】 A lot of kids struggle with reading. Parents have tried encouraging them in all sorts of ways, but nothing seems to work. Actually many factors(因素)can cause reading problems.【1】 Here are a few things you can do to help your kid become a better reader.

Read to your kid-and have him/her read to you

Grab one of the books you loved when you were your kid's age and read it to him/her or take turns reading it to each other. 【2】 Make reading a regular part of the night-time routine.

Don't be pushy

Just because you're a science fan or read on history and other nonfiction doesn't mean your kid will be remotely interested in any of those things. In fact, you've been pushing your tastes on your kid. 【3】

Choose books that interest your kid

Most kids love movies. Did your kid like Ready Player One or Ender's Game? They are based on books. 【4】 If your goal is to get your kid interested in reading and improve his/her skills, what your kid's reading is less important than how much time he/she spends doing it.

【5】

Kids who have trouble reading often feel that there's something wrong with them. So work with your kid to come up with manageable goals and make a big deal every time he/she accomplishes one. With time, gradually make the goals more challenging.

A.Achieve your goals

B.Celebrate small steps

C.Reading books can help your kid get a head start in school.

D.If your kid stops or makes a mistake, be patient and don't judge.

E.Overcoming them can sometimes be an annoying process for everyone.

F.Starting with something your kid is already interested in could help draw him into reading.

G.You may have contributed to his/her reading problems rather than helping overcoming them.
