4 . All forms of tobacco — cigarettes, pipes, cigars, and smokeless tobacco — are dangerous. It doesn’t help to substitute products that seem like they’re better for you than regular cigarettes, such as filtered or low-tar cigarettes.

The only thing that really helps a person avoid the problems associated with smoking is staying smoke free. This isn’t always easy, especially if everyone around you is smoking and offering you cigarettes. It may help to have your reasons for not smoking ready for times you may feel the pressure, such as “I just don’t like it” or “I want to stay in shape for soccer (or football, basketball or other sport)”．

The good news for people who don’t smoke or who want to quit is that studies show that the number of teens who smoke has dropped evidently. Today, about 23% of high school students smoke.

If you do smoke and want to quit, you have lots of information and support available. Different approaches to quitting work for different people. For some, quitting cold turkey is best. Others find that a slower approach is the way to go. Some people find that it helps to go to a support group especially for teens. These are sometimes sponsored by local hospitals or organizations like the American Cancer Society. The Internet offers a number of good resources to help people quit smoking.

When quitting, it can be helpful to realize that the first few days are the hardest. So don’t give up. Some people find they have a few setbacks before they manage to quit for good.

Staying smoke free will give you a whole lot more of everything — more energy, better performance, better looks, more money in your pocket, and, in the long run, more life to live!

5 . Floor sweeping robot, also known as automatic cleaner, intelligent dust collector, robot vacuum cleaner, is a kind of intelligent household appliances, which can automatically clean the floor in the room with a certain amount of artificial intelligence. Brush sweeping and vacuum are generally used to absorb the ground sundries into their own garbage storage box, so as to complete the function of ground cleaning. Generally speaking, robots that complete cleaning, dust collection and floor cleaning are also uniformly classified as floor sweeping robots.

Recently, my family has a new member. It has a foolish name called “JoJo”. It is a “sweeping robot”, with a round, flat body, wearing a silly coat and shining like a scammony. To be honest ,I turned my back on it. It has several functions! It has a powder in its stomach. When it first sweep a lot of dust together, it will eat them all in its body. As long as it is touched gently, it will climb around on the ground and start working hard.

It has a pair of sensitive infrared “eyes”. When encountering obstacles in front, it will drop its head as fast as driving. When it feels that there is garbage around it, it will run towards the garbage and sweep it clean. Every night, when I finish my homework, there is no paper dust on the whole floor. It can also make an appointment and work regularly. After completing the task, it can find its own charger to charge, which is very powerful. Since it came to our home, it has become a good helper for our cleaning. My mother said, “this is the power of science and technology!”

Although its look is completely stupid but it have helped me a lot in cleaning. So I hope scientists can invent many capable robots like JoJo in the future.

1. Where does the sweeping robots put the garbage?

A．The trash-bin in the house.	B．Their own trash box.

6 . 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。

Lizard (蜥蜴) Problems

My problems started when I learned that Mrs. Smith would be my fourth-grade teacher. She had a lizard in her classroom, and lizards were on my list of terrifying things.

Worse, Richard was in my class again. He knows I’m afraid of spiders (蜘蛛), and all year he pretended to put them in my hair. If he found out lizards were on my list, I’d be finished.

On the first day of school I tried not to look at the glass container in the corner, but Mrs. Smith pulled out the lizard and set him against her shoulder like a baby. “This is Ripley”, she said.

Richard whispered, “Bet you’re scared of him.” “I am not!” I said. Mrs. Smith looked toward Richard and me. “What’s wrong?” she asked.

“Amy’s scared of Ripley” Richard announced. “No, I’m not.” My chest tightened. “I love lizards. They’re my favorite animals.”

Mrs. Smith smiled. “I was going to ask for a volunteer to feed Ripley at recess (课间休息), but since you’re a lizard lover, how would you like the job?”

She probably thought I was speechless with joy.

Before recess, Mrs. Smith showed me Ripley’s bag of greens. I can handle that, I told myself.   I’ll just lift the container lid (盖子), drop in the greens, and run.

As Mrs. Smith led the class out the door, I was frozen in a block of ice. I wanted to cry, but my tears were frozen, too. Ripley sat still watching. I knew he was waiting to jump at me the second I lifted the lid. I just stood there for a long time, staring back at Ripley.

Voices in the hall told me recess was over. I closed my eyes, lifted the lid, threw in the greens, and shut the lid. Mrs. Smith said, “You must be enjoying your job, Amy You didn’t come out for recess at all.”

Richard’s eyes got wide. I’d fooled him. But now I’d have to spend every recess with a lizard.

注意:1.续写词数应为150左右； 2.请按如下格式在相应位置作答。

After a few weeks, Richard said “Why does Amy always get to feed Ripley? I want a turn.”

______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

I meant for Richard to put Ripley down inside the container, but Richard set him on the floor and ran outside.

8 . How is it that a fly always seems to be buzzing around your food moments after you sit down for an outdoor meal?

The answer is practice. Or, more specifically: evolution (进化). Flies and other insects have been on a multimillion-year journey of evolution, improving their ability to detect food. Being able to zero in on nutritious meals is a matter of life and death.

The family of flies that I study — the blowflies — are the buzzing ones that are usually a beautiful metallic blue, with bronze and green colors. They’ve perfected their ability to quickly sense the smells that naturally come off picnics and garbage cans. There is a lot of competition for a resource like an overflowing garbage can because of how nutritious garbage, with the meat rotting in it, is. But the blowflies can sense these smells long before their competitors or people can, and tend to show up to the scene first.

Sensing systems differ depending on the insect and species. The blowflies’ main sensing organ is their antennae, two thin projections (凸起) from the head that are covered in tiny hairs. These fine hairs are made up of special cells that contain receptors (受体) for specific smells. Think about a batch of chocolate chip cookies fresh from the oven. You can detect their delicious smells because we humans have receptors on the surfaces of the cells that line the inside of our noses. These receptors send signals to the brain: yummy food ahead. They’re detecting the sweet smell of sugar-based molecules, an energy-rich food source for us.

What’s a “good” or a “bad” smell can differ depending on the animal doing the smelling. The attractive rotting meat stench(恶臭) that a fly finds delightful is perceived quite differently by a person passing by an unpleasant garbage can on a hot day. But any fly that can detect the useful smell signal, which means “nutritious fly food here”, will have an advantage. Over time, the insects that have the receptors for those smells will have better survival rates and produce more generations.

A．By explaining a principle.	B．By making a comparison.
C．By following time order.	D．By describing a process.

4. What’s the message implied in the last paragraph?

B．Nutritious foods usually have attractive smells.

C．The receptors play a key role in flies’ survival.

D．Flies find a smell signal much faster than humans.

9 . Researchers have developed a robotic sensor that combines artificial intelligence techniques to read Braille (盲文) at speeds roughly double that of most human readers. The research team, from the University of Cambridge, used machine learning algorithms (算法) to teach a robotic sensor to quickly slide over lines of Braille text.

The robotic sensor the researchers used has a camera in its “fingertip”, and reads by using a combination of the information from the camera and the sensors. “This is a hard problem for roboticists as there’s a lot of image processing that needs to be done to remove motion blur (模糊), which is time and energy-consuming,” said Parth Potdar from Cambridge’s Department of Engineering.

“There are existing robotic Braille readers, but they only read one letter at a time, which is not how humans read, ” said Potdar. “Existing robotic Braille readers work in a static way: They touch one letter pattern, read it, pull up from the surface, move over, lower onto the next letter pattern, and so on. We want something that’s more realistic and far more efficient. ”

The team developed machine learning algorithms so the robotic reader would be able to “deblur” the images before the sensor attempted to recognise the letters. They trained the algorithms on a set of sharp images of Braille with fake blur applied. After the algorithms had learned to deblur the letters, they used a computer vision model to detect and classify each character.

Once the algorithms were incorporated, the researchers tested their render by sliding it quickly along rows of Braille characters. The robotic Braille render could read 315 words per minute with 87% accuracy, which is twice as fast and about as accurate as n human Braille reader.

“Braille reading speed is a great way to measure the dynamic performance of tactile(能触知的)sensing systems, so our findings could be applicable beyond Braille, for applications like detecting surface textures or slippage in robotic manipulation,” said Potdar.

In the future, the researchers are hoping to scale the technology to the size of a humanoid hand.
