When you think of robots, what is the first thing that comes to mind? Do you think of science fiction movies like Star Wars, where robots of all shapes and sizes are part of daily life? The word “robot” itself comes from a play written in 1920 by Karel Capek. In the play, people create robots to do some everyday tasks.

Today, most robots don’t look human. Modern robots take many forms and are good at many things, from sweeping the floors in your home to working in factories. They are even exploring the surface of the moon. But there is an interesting irony(讽刺) in the world of robotics which describes a surprising problem: What humans find easy is extremely complicated for a robot. However, what humans find difficult is pretty easy for a robot. For example, picking up clothes in a messy room is simple for people. But that kind of chore is very hard for a robot. Another example is the game of chess. People might find it difficult to win the game of chess all the time. But robots like Alpha-Go can be programmed to play it very well.

This is because robots are very good at doing things in controlled environments. However, moving through a room filled with random(随机的) objects is hard for robots, along with picking up objects of different shapes and sizes without damaging them. In short, it is very difficult for them to deal with certain types of variables.

It turns out that one of the most difficult things to improve in robots is their ability to control objects. Luckily, great progress is being made in the development of robots. On the one hand, exciting developments in making human-like hands and legs are underway. On the other hand, the biggest progress might result from using virtual learning(虚拟学习) to “teach” robots through computer simulations(模拟). In this way, robots can “guess” what to do without an order when they meet unfamiliar things in the real world.

Soon, robots may be able to do those things that humans find simple. That means big changes in what robots can do and how they can help us with daily tasks. Robots might make movies a reality.

1.What’s the purpose of the first paragraph?

A.To give an example.

B.To present the topic.

C.To explain what robots are.

D.To show how robots develop.

2.According to the passage, what might be difficult for robots?

A.Playing chess.

B.Washing the dishes.

C.Making cars in factories.

D.Gathering up clothes in a mess.

3.What’s the writer’s opinion about robots in the future?

A.They will cause further problems for people.

B.They will deal with new things depend on orders.

C.They can hardly develop until they look like human.

D.They can benefit people more by making improvements.

What is the first thing that comes to your mind when you hear the word”hero”? 1. There are onscreen heroes like the superheroes in Avengers(复仇者)，and also everyday heroes in our lives.

Whether they’re championship athletes, groundbreaking(开创性的)scientists, programmers changing the world with a keyboard, firefighters rushing into the burning building, artists creating the works of amazement, or a dog with a baby by his side, “hero” can be the word to describe them.

2.

In general, a hero is someone selfless, courageous and brave. These qualities drive heroes to help others in times of need, even if they are scared. You can count on them to be there for you if something bad happens.

“The people that we set up as heroes are people that generally go above and beyond the call of duty.3.” Nick Carden, a psychologist at the AAPHC Renaissance Center in the US said so.

However, why can some people be heroic? Nick Carden said, heroes are made. “They probably are people that have been influenced by and have been helped by or have been modeled or raised to have those as values.”

Common people—just like you and me—are heroes in their own way, simply just by doing their part for their families and communities. Cleaners, doctors, reporters, delivery workers, nurses, and bus drivers—the list goes on and on.4. And, sometimes, when there are emergencies, these common people show courage and bravery to help complete strangers in need.

Being a hero is the nature of human beings. “The decision to act heroically is a choice that mans or us will be called upon to make at some point in time. Heroism becomes something that seems in the range（范围）of possibilities for every person, perhaps inspiring more of us to answer that call.” heroism researchers Zeno Franco and Philip Zimbardo wrote in Great Good Magazine.5. Be courageous, honest, and a person with integrity(正直). Because, once you are your own hero, you can truly do anything you set your mind to.

A.These common people help keep order in our day-to-day lives.

B.Is it someone who wears a cape(披风）and can fly in the air?

C.Only in this way, you can be your own hero.

D.Most importantly, you should make an effort to be your own hero.

E.They do things that are outstanding.

F.But what makes a person a hero?

What’s the first thing that you notice when you walk into your favorite restaurant? Is it the smell of fresh pizza, or the sight of your favorite desserts? Food that looks and smells good will probably taste good, but what about sound? Is that important?

Scientists now believe that the taste of food can change when your ears hear different sounds, but it has to be the right kind of sound. When you turn on a microwave with popcorn in it, it soon starts to pop. Do you think “That sounds tasty!”? Not really, you probably think it’s nearly ready. But when smell it, you go to get the salt and the butter. Hearing the popcorn make you think about it, but smelling it tells you that it tastes good. So what are the sounds to change the tastes of the things?

In an experiment in a fish restaurant, customers listened to the sound of the seaside while they were eating. Did it make a difference? Yes, it did. Listening to the seaside seemed to improve the taste of the food. It was fresher and saltier. When the restaurant tried the same experiment with the sound of the farm animals, there was no difference in taste. The results are going to be useful for restaurants. Perhaps they will try to use fewer unhealthy things, like salt and sugar in food. With the right music or sounds, perhaps we won’t taste the difference.

Restaurants are also setting a connection between food and the sound that the packet(包装袋) makes. Pick up a packet of your favorite potato chips, what does it sound like? One restaurant recently changed the material that they used to make their potato chip packets because experiments show that the packet which makes a right sound will make customers think the potato chips are fresher. Another idea is that a list of music will begin to appear on food packets, so if you don’t like your green vegetables, the right music or sounds could help you learn to love them.

1.According to the passage, what makes you think the popcorn tastes delicious?

A.Turning on the microwave. B.Smelling the popcorn in the microwave.

C.Hearing the popcorn. D.Taking the popcorn out of the microwave.

When you think of American culture, what first comes to your mind? McDonald’s? Coca Cola? Levi’s? Disneyland? Michael Jordan? Julia Roberts? Many people imagine American culture is a collection of popular symbols like these. Actually, these symbols are only one small part of American culture — pop culture.

What is pop culture? Well, pop is short for popular. The origins of pop culture can often be traced(追溯) to popular movies, television shows, music stars and sports figures. Pop culture is also promoted by business and advertising. The most common examples of American pop culture appear among high school and college students. Trends(潮流) set by famous people quickly become part of young people’s lifestyles.

American pop culture has spread around the world. One major reason for its popularity is that English is a world language. English is the language of diplomacy, international business and transportation. Since language and culture go together, learning English means becoming aware of English-speaking countries’ cultures. Also, America is a world leader in movies, music and magazines. The kind of American culture communicated in those media is pop culture. Finally, pop culture is easy to package and to export. For that reason, it is easy to “sell” to the world.

Many people suppose that American pop culture is what America is all about. Does pop culture reflect(反映) the true culture of America? Yes and no. Pop culture does represent(代表) a part of American society — especially urban young people that are turned into the media. But American pop culture is faddish and ever-changing. It is man-made and surface picture of America. If you want to learn about real American culture, you’ll have to go a little further than McDonald’s.

1.Paragraph 3 is mainly about 　　　　　　　　　 .

A.why language and culture go together B.how American pop culture leads in media

C.why American pop culture is popular D.how American pop culture is exported

2.The underlined word “export” probably means 　　　　　　　　　　 .

A.to buy from a foreign country B.to sell to a foreign country

C.to send to others D.to store in some places

3.Which of the following is TRUE about American pop culture according to the passage?

A.Pop culture isn’t a part of American culture.

B.Young people always set the trends of pop culture.

C.It is popular in the world mainly because of the popularity of English.

D.If you want to know real American culture, you can go to McDonald’s.

4.What can we infer from the passage?

A.American pop culture is a part of American culture.

B.McDonald’s, Coca Cola, Levi’s etc. are all symbols of American pop culture.

C.American pop culture is easy to sell to the world only because it’s popular.

D.To learn about real American culture, you should study more than pop culture.

“I will think of it.” It is easy to say this, but do you know what great things have come from thinking?

Sir Isaac Newton was sitting in his garden when he saw an apple fall from a tree. He began to think and tried to find out why the apple fell. Then he discovered how the sun, moon, and stars are kept in their places.

A boy named James Watt sat quietly by the fire, watching the lid of the kettle move up and down. He wanted to find out why the steam in the kettle moved the lid. From that time he went on thinking and thinking. And when he became a man, he improved the steam engine (蒸汽机) so much that it could easily do the work of many horses.

James Ferguson was a poor boy. Once, seeing the inside of a watch, he wondered. “Why should I not make a watch?” But how could he get the materials to make the mainspring (钟表的主发条)? He soon found he could make it with whalebone (鲸骨). He then made a wooden clock which kept good time. His motto (座右铭) was “I will think of it.” And he made his thoughts useful to himself and the world.
