【題目】 Today scientists are creating cool designs with smoother moves. Let’s check out the science behind four awesome robots.

TYPES

HOW IT WORKS

WHAT IT MEANS FOR YOU

T-HR3

The two-legged walking robot imitates the way people move. A human operator wears a headset with cameras that show what the robot “sees”. The human can then control the robot’s actions with his or her own human movements.

With a human helper, T-HR3 could assist people in medical facilities, burning buildings, construction sites, and even space. Its creators hope that T-HR3 will learn to do some tasks itself one day …like, say, your chores, maybe?

SHAPE-SHIFTIING

When a scientist programs in a shape/ the motors change different parts of the surface to make it look like whatever the scientist wants! The shape-shifting robot can be programmed to look like just about anything small and enter tiny space.

In addition to helping scientists secretly observe animals, the shape-shifting robot might one day be used to create more immersive virtual reality experiences. Imagine being able to touch objects in your VR game and not just see them!

SALTO

Rescuers have long used remote-controlled robots to search through nibble. But what’s special about Salto is its jumping ability, enabling it to reach places humans can’t. Twisted rubber bands in its legs make it bouncy enough to leap to high spaces.

Salto’s not just helpful in emergencies. Its technology might one day help fetch things from hard-to-reach places in your home, like that candy bar you hid on the top shelf of the cupboard.

SPOTMINI

The four-legged robot is designed to help with house chores. With its extendable arms, Spotmini can unload dishes and put them in high shelves, grab debris (碎片) in hard-to-reach places. It can even climb stairs.

Experts say future homes will have robots doing chores so that people have more free time. Instead of earning your allowance by taking out the garbage, you might be doing robot repairs instead.

【1】If you want to take a close picture of a poisonous snake, which robot is the most suitable?

A.T-HR3B.SHAPE-SHIFTINGC.SALTOD.SPOTMINI

【2】What these robots have in common is that they .

A.work by using a remote-control

B.are designed to help with the housework

C.enable people to see whatever they “see”

D.carry out tasks where humans are hard to reach

Oh, a pity! It’s raining again? Is everybody here? Good. Now listen carefully. I wish the weather is better here for you. It’s very usual to have so and so much snow and rain here at this time of year.

Some of you are asking about tomorrow’s activity on the way here. Well, we’re going to climb the mountain unless the weather gets much better during the night. OK? So, provided that it doesn’t snow too heavy tonight, I’ll see you back here at six o’clock. Set your alarms for 5:30. We’ll take our breakfast with them because we won’t reach the top of the mountain unless we set out early, before it’s light. So be there tomorrow morning with everything you need. You’ve all got a list—you need a whistle in case you get separated from the rest of the group, warm waterproof clothing and gloves, and a good pair of boots. Don’t forget to bring maps I gave you yesterday. I’d rather you didn’t bring large cameras and video cameras.

It’s time we had dinner now, so if that anyone has any questions, you can ask me on the way to the dining hall. Let’s go.

Everyone should take the action to reduce haze(霧霾)，which is harmless to our health．First of all，I believe that if we plant more tree，there will be less haze in their city．Trees can absorb exhaust fumes(尾氣)from cars，thus reduce pollution．Second，the government should punish the factories where produce too many fumes．Exhaust fumes is the main cause of haze and do greatly harm to people’s health．Maybe we can move factories to areas where few people live．Third，I think it was a great idea to encourage people to use public transportation．Last but not least，we can call on citizens ride bikes if they travel short journeys.
