阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。

My father asked me to chat with him for a while. Actually, I was unwilling to listen to his talking endlessly as he always did. My father was a lawyer, but I never wanted to go to law school or follow his path through life.

As was expected, he cleared his throat and started to say, “Er... What... What do you really want to do in the gorgeous(灿烂的) future?”

I was silent for a moment playing with the cell phone. I kept thinking, “Should I tell him my true thoughts? What if he gets angry? What if I let him down?” later I replied, “Well, I want to be a writer.”

I guessed this may be not the answer he would expect. But surprisingly, “Interesting idea!” he answered. I was shocked, speaking in a low voice with hesitation.

“Are you serious, dad?”

“Well, you need confidence and good preparations, and you still have plenty of time. You need to find out what you really enjoy now. Look, it’s late. Let’s take the boat out tomorrow morning, just you and me. Maybe we can catch some crabs (螃蟹) for dinner, and we can talk more.”

Early next morning we packed up the equipment and set off for the coast. We didn’t talk much, but enjoyed the sound of the seabirds and the sight of the coastline.

There were no big waves and blinding sunlight at that time. “Let’s see if we are lucky,” he said, picked up a web basket with a rope tied and threw it into the sea. We waited a while, then my father stood up and said, “Give me a hand with this,” and we pulled up the crab cage onto the deck.

To our joy, the cage was filled with dozens of soft shell crabs. Squatting (蹲) down, we watched them for a moment. At first they fought against each other to climb out hard, trying to escape. Many were pulled back into the cage. Later, some gave up, but there were still some crabs trying to escape again and again.

注意:
1. 续写词数应为150左右;

At that moment, my father pointed to the cage, “Look at that crab, there!”

阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。

It was a typical Monday morning. My form teacher, Mrs Tan, was going through our exam questions. I pot down some notes and did my corrections.

“Riiiiiiinnnngg!” A high-pitched sound pierced through the air like a knife. Covering my ears in annoyance, realization dawned on me. It was the fire alarm! While I encouraged others to remain as cool as a cucumber, it was in vain. My classmates were all screaming and running around like crazy.

“Calm down, everyone! Please queue up in an orderly manner! We have practised this in the fire drills!” instructed Mrs Tan , sounding anxious.

The class ignored her and continued screaming at the top of their voices. One student even broke down in a fit of panic. I rushed around the class, asking all my fellow students to settle down while waiting for further instructions.

A serious voice soon announced from the speakers in every class, drawing our attention. “All students are to follow their teachers and evacuate(撤离)the building in a calm and organized manner. The fire may have been caused by a gas explosion in the canteen; do not go near there!”

Mrs Tan finally managed to calm the panicky class down. In a strict voice, she told us that we were to use the evacuation route to Gate 6. She arranged the pupils quickly in neat straight rows and led us out of the classroom.

Upon taking my first step out of the classroom, I took a deep breath instantly. The surroundings were hazy(模糊的) as thick smoke came from the canteen. Choking, I unconsciously covered my nose. To make matters worse, the ash from the smoky surroundings hurt my eyes. Coughing anxiously, I tried to see my teacher in the lead, but the air was too hazy for me to see anything clearly. Within less than a minute, I lost sight of my class and was left alone.

注意:1. 续写词数应为150个左右;
2. 请按如下格式在答题卡的相应位置作答。

A wave of anxiety washed over me.

Just then, the figure of Mrs Tan waving a torchlight appeared from the smoke.

用方框中的单词完成下列短文,每个单词只能使用一次。
A. pleasant B. worthwhile C. lanes D. complaints E. appreciate F. hit G cold
H. sample   I. rising , J . differently K. identically

I am not an enthusiastic air traveler. Bustling through airports, getting checked by security, and standing in lines leave me 1.. But road trips are different. While the transit time is longer, opportunities to get off the beaten path(常走的路) make it 2.. I see places and interact with people and cultures that I otherwise tend to miss, rediscovering how far you can go and how much you can experience without leaving the United States. So, when my son said he wanted to tour the Kansas State University campus after receiving an admission offer, we threw our luggage and a case of bottled water in the car and 3. the highway. One attraction of traveling at the speed of a car is the transitions. Arizona's Meteor Crater(陨石坑), Two Guns, and Painted Desert give way to New Mexican villages, then farm towns. Red rocks become open plains and grain elevators are the only features 4. above endless miles of flatness.

That flatness poses an unexpected challenge when there's nothing to step behind. Eating on the road can also be a challenge. For basic food, Anthony and I relied on Subway sandwich shops, which offer the same reliable fare(饭菜) at every location. While not exactly a 5. of local cuisine, they didn't leave us regretting lunch when we returned to clocking miles. Salads were curiously difficult to find in the college town of Manhattan, Kansas, although we had no 6. about the burgers and barbecue.

In contrast to airport excursions, which often feature conflicts and even confrontations, our trip was entirely 7.. When you meet folks in their natural environment after hours of changing scenery, it's easier to remember just how big the world is and to 8. that many of its inhabitants are perfectly happy living 9., and there's no reason they shouldn't be.

As it turned out, the greatest source of stress was the frequent reminder that my son changes 10. like he's afraid of missing a sharp turn. Fortunately, that's a travel headache that can be fixed.

Studying a subject that you feel pointless is never a fun or easy task. If you’re studying history, asking yourself the question “why is history important” is a good start. 1. You will find something here that will arouse your interest, or get you thinking about its significance.

2. History is an important and interesting field of study, and learning the history of our home country can give us a deeper glimpse (一瞥) into our ancestral pasts, and how we got to where we are today. Many people feel like they need a sense of cultural belonging, which is something that studying your roots can provide.

History enriches our experience. Reading history is an amazing experience because it enables us to reflect on the social and economic life of the people living long time ago. According to the experts, problems faced by people regardless of the past and present are the same. 3.

History makes us more empathetic(具有共情能力的). Studying history can give us insight into why our culture does certain things, and how the past has shaped it into what we know now.   4. Fear and hate for others is usually caused by ignorance(无知). History has the potential to break down those boundaries by offering us insight into entire worlds that would otherwise be foreign to us.

History can inspire us to learn more. 5. It’s almost impossible to learn about one historical period without having dozens of related questions. Study the 19th century England, and you might catch a glimpse of Charles Dickens’ Oliver Twist. Or maybe you end up switching your attention away from novels, and discover the history of romantic poets in England. It can go anywhere for anybody.

A.History grounds us in our roots.
B.History helps us develop our interest.
C.History is an essential part of human civilization.
D.What’s fantastic about history is the way it broadens our horizons.
E.Being empathetic means listening to and understanding someone else.
F.It also provides a rather strong foundation for empathy across cultures.
G.With the information about the ancestors, one can become more experienced in handling challenges of life.

If a pancake could dream, it might long for legs so it could jump off your breakfast plate in pursuit of a better, unchewed life. But legs aren’t necessary for something as flat as a pancake to jump around. A group of scientists have designed a pancake-shaped robot that can jump several times per second and higher than seven times its body height. The new robot named Hop, which swiftly jumps without feet, is an important contribution to the soft robotics.

Many ground robots move by rolling or walking. But it’s more efficient for robots to jump over obstacles (障碍物) than to go around them. Although jumping can offer some robots a competitive edge, engineering that ability has been a challenge for robotics researchers. Some soft robots that store energy can perform a single impressive jump very infrequently. Some lightweight soft robots that don’t store energy can jump frequently but can’t jump high or far enough to successfully cross an obstacle.

For inspiration, the researchers looked to gall midge larvae (瘿蚊幼虫) that miraculously throw themselves across distances 30 times as long as their loglike bodies. A gall midge larva bends its body and squeezes the liquid in its body to one end, making it rigid (僵硬的). The accumulation of liquid builds up pressure, and releasing the pressure sends it soaring (飙升). The robot’s body doesn’t resemble (像) that of a gall midge larva, but it jumps like one. Its body is made of two small plastic bags printed with electrodes; the front bag is filled with liquid and the back one is filled with the same volume of air. The robot uses electricity to drive the flow of liquid, which causes the body to bend and generate force with the ground, resulting in a jump. And the air bag imitates the function of an animal’s tail, helping the robot keep a stable position.

While the robot is currently restricted to Earth, it might be right at home exploring another planet. If this is true, the researchers robot might jump over dusty rocks and large holes on the moon or Mars, going where no pancake has gone before.

1.What does the author want to show by mentioning a pancake?
A.A pancake’s dream to have legs is unrealistic.
B.A robot is capable of serving a good pancake.
C.A pancake-shaped robot can jump without legs.
D.Research on pancakes advances our understanding of robots.
2.What difficultly do robotics researchers have in developing Hop according to Paragraph 2?
A.Hop’s avoiding an obstacle.B.Hop’s moving around by rolling.
C.Hop’s performing one remarkable jump.D.Hop’s jumping high and far continuously.
3.What inspiration do the researchers draw from gall midge larvae?
A.They are shaped like logs.
B.They have tails to change positions.
C.They bend their bodies and increase force.
D.They are filled with liquid and have rigid bodies.
4.What is the author’s attitude to the future of the new robot?
A.Intolerant.B.Positive.C.Indifferent.D.Ambiguous.

A man recently connected with me on LinkedIn and sent me this note: “Let me know if you ever need a writer.” I guess he’s a writer? I don’t know. But I do know this phrase “Let me know if you ever need a.” shows up a lot, in my inbox and surely yours, too. I’ve come to think of it as the eight most deadly words in selling oneself because that phrase is the death of opportunity.

Let’s consider the approach. These people are being standoffish. Rather than selling themselves, they’re shifting the burden onto someone else to make the sale. If I need a writer, I should reach out to them. If I need a story, I should ask them for an interview. If I need a customer service solution, I should ask them for details. “Let me know if you ever need a ... ” sounds like an invitation, but it’s really a shrug.

Imagine the situation where I’d assign (分派工作) a story to the writer who used the nine words, “Let me know if you ever need a writer.” I would have needed a writer. Just any writer. Just anyone who can string words together. I would have needed to be in a panic, so desperate for someone to contribute to our magazine that I’d stopped thinking about great writers or good writers, or even serviceable writers and simply settled for a writer. This isn’t a situation that exists. The world is full of good options! We are not living in times of shortage. If we need a job done, there are plenty of qualified people to do it. Our question is: Who’s the best?

If you want to create opportunity for yourself, answer that question convincingly. The first thing to do is show someone you are the opportunity. Hiring you can help them. We also need to stop hiding behind ourselves. Get out in front! Sell yourself and your amazing abilities. Understand someone’s problem, and explain exactly why you are the solution. Avoid saying “Let me know if you ever need a ... ” Instead, start with: “Let me explain how I can help you.”

1.What do we know from the author’s experience?
A.We’d better start our own careers as early as possible
B.The author prefers to hire his employees on Linkedln.
C.The phrase “Let me know if you ever need a ... ” is polite.
D.Many people use the wrong opening sentence to sell themselves.
2.What does the underlined word “standoffish” mean in Paragraph 2?
A.Frank and open.B.Unfriendly and proud.
C.Unsure and sensitive.D.Concerned and confident.
3.What can be inferred from Paragraph 3?
A.The author is in desperate need of a writer’s help.
B.There are very few great writers available nowadays.
C.Anyone who can string words together is a good writer.
D.The author isn’t interested in the writer using the nine words.
4.What can be the best title for the text?
A.A Better Way of Selling Yourself.B.Full Preparations Matter Most.
C.Good Jobs Wait for No Man.D.Politeness Makes Difference.
