There was an Internet already but it was difficult to use.In 1989,Tim Berners-Lee invented the World Wide Web(WWW)all by himself.This had a special language that helped computers talk to each other on the Internet.When people wanted to share information with others,they used the World Wide Web.The Internet grew quickly after that.

Tim Berners-Lee doesn't think he did anything special.He says that all of the ideas about the Internet were already there.All he did was to put them together.He says that many other people worked together to make the Internet what it is today.

【推荐1】If you're planning to go on a diet, or if you suffer from serious conditions like diabetes (糖尿病), knowing exactly what and how much you're eating is essential. In this day and age, we have calorie and nutritional calculators even on our smartphones, but they act only as guides, whereas Panasonic's revolutionary new device, CaloRieco, actually analyzes the food on your plate and provides accurate information about in just a few seconds.

You've probably used calorie calculators before, and you know that they only offer general information. For example, a calculator will tell you the average number of calories in a hamburger, but it can't tell you exactly how many calories are in the hamburger. The same goes for nutrients like protein or fats. And this is what makes the new CaloRieco so special.

Displayed at a recent tech show, CaloRieco is a high tech device that uses light reflection technology to determine the nutritional values of almost any food and also provide accurate calorie estimates. All you have to do is put your plate in the box-shaped device and wait between 10 and 20 seconds for it to analyze all the food on there.

Once it's done analyzing the various ingredients in your meal, CaloRieco displays the number of calories, as well as the nutritional content on an LED display. According to Panasonic, the device is able to recognize the vast majority of foods, except soups and very dark dishes.

CaloRieco can also connect to your smartphone via an app, and send all the data about analyzed foods to your handheld, so you can access it whenever you need.

Panasonic said that its outstanding invention is aimed at dieters and diabetes sufferers, both of which make up a sizable market. Unfortunately, you'll have to wait a bit longer to get your hands on your very own CaloRieco, as the device presented at the show is just a prototype (样品) which needs to be improved. It's scheduled to hit the market sometime in the next few years, but the price remains a mystery.

1. What is special about CaloRieco?
A.It is a high-tech device working as a guide.
B.It makes use of light reflection technology.
C.It only offers general information of food.
D.It can present the exact data of analyzed food.
2. What do we know about CaloRieco?
A.It needs a long time to analyze the food.
B.It can count the calories of all kinds of food.
C.It can display the food data on the smartphone directly.
D.It may be well received among dieters and diabetes sufferers.
3. What does the underlined word "it" in Paragraph 5 refer to?
A.Smartphone.B.App.C.Data.D.Food.
4. What can we infer about CaloRieco from the last paragraph?
A.It's perfect.B.It's promising.C.It's costly.D.It's portable.

文章大意:这是一篇说明文。本文介绍了异种机器人的产生,并具体说明异种机器人繁育机制、本质、应用前景,以及引发的争议。

【推荐2】Living robots can reproduce on their own in a dish. This is not a science-fiction movie, but the result of a new research.

Xenobots, a type of tiny robot, were first created in 2020, using cells taken from the embryo (胚胎) of an African frog species. Under the right lab conditions, the cells formed small structures that could self-assemble (自组装), move in groups and react to their environment. Now, the researchers have found that xenobots can also self-reproduce, according to the journal-New Scientist.

Xenobots step over an unusual line. Are they living organisms or robots? They are organisms because they are made of stem cells and can reproduce. But they are also robots because they can move on their own and perform physical labor, co-author Sam Kriegman told The Washington Post.

“People have thought for quite a long time that we’ve worked out all the ways that life can reproduce or copy. But this is something that’s never been observed before,” co-author Douglas Blackstone, a senior scientist at Tufts University   in the US, told Science Daily website.

The ability to copy adds a new layer of potential function to the robots. Kriegman told The Washington Post that while xenobots are not yet commercially useful, they have the potential to offer a number of services, from cleaning up microplastics in the ocean to safely delivering drugs to a specific spot in a person’s body.

However, the creation of xenobots comes with concerns. Some think more advanced future xenobots, especially ones that live longer and reproduce, could out-compete other species, according to The Conversation, an Australia news media.

Researchers think these risks are manageable. “If you change the amount of sodium (钠元素) in that water to be too high or too low, they’ll die, ”Kriegman told The Washington Post. “If there’s a piece of copper, a kind of metal, in the dish, they’ll all die. It’s an extremely controllable, stoppable and safe system.”

1. What are xenobots?
A.Robots first discovered in 2020.B.Robots from a sci-fi movie.
C.Organisms made of embryos.D.Organisms as well as robots.
2. What is the promising benefit brought about by xenobots?
A.Promoting commercial products.B.Offering some household services.
C.Delivering medicine inside a patient.D.Cleaning up huge plastics in the ocean.
3. What can you infer from Kriegman’s words in the last paragraph?
A.Xenobots die hard in water.B.Xenobots won’t pose a threat.
C.Xenobots are made of copper.D.Xenobots have a safe system.
4. What is the purpose of the passage?
A.To inform us of the creation of Xenobots.B.To instruct people how to use Xenobots.
C.To warn about the danger from Xenobots.D.To settle the arguments over Xenobots.

文章大意:本文是一篇记叙文。文章主要讲述了Sila Sutharat如何利用太阳能把普普通通的泰国烤鸡卖得火爆的故事。

【推荐3】In Thailand, gai yang—or grilled chicken—might not sound like the most extraordinary dish. Yet the necessity for customers to order it days ahead in Sila Sutharat's food stall (小摊) if they want to try some is a proof that ordinary things done creatively are far more attractive than extraordinary things done ordinarily,

One day, I stopped by a place where a man named Sila Sutharat was grilling chickens in perhaps the most extraordinary way possible. Unlike the coal-fire-licked chickens that are so common in Thailand, Sutharat's was cooked with the extraordinary heat source: the sun.

About 60 miles from Thailand's capital city Bangkok, Sutharat's solar grill—a huge, adjustable wall of polished mirrors—could be seen standing out from among the trees on a small side road. Depending on the time, you might see Sutharat standing in the back adjusting the chickens that sat at the center of the focused light—estimated to exceed temperatures of 200℃.

He was inspired, by chance, in 1999, when a tour bus with reflective side mirrors drove past while he was walking to his former food stall. Surprised by the heat given off, he was soon exploring ways to use mirrors to grll chickens.

It might seem a basic principle of physics to me, but Sutharat's creation had not always been a smooth sailing. "My wife thought I was stupid. The neighbors said I was crazy, "Sutharat said of the early days of trial and error. The first grill was built with 300 mirrors, but it didn't cook the food fast enough and struggled with cloud cover. So Sutharat decided to increase the number of mirrors to 1, 000 until a whole gai yang could be cooked in 12 to 15 minutes.

Without any of the usual blackened skin, the flavors of the chickens are far more pronounced. Actually, more and more people have noticed the difference. These days, you'll have to order days ahead if you want to try some.

1. What has made Sila Sutharat's food stall so special?
A.The unique kind of heat.B.The high temperature of the grill.
C.The huge size of the grillD.The good position of the food stall.
2. What does the author think of the working principle of Sutharat's grill?
A.Stupid.B.Creative.C.Complex.D.Simple.
3. What does the underlined word "pronounced" in the last paragraph mean?
A.Disgusting.B.Different.C.Strange.D.Bitter.
4. What is the author's purpose in writing the text?
A.To explain how to grill Thai chickens.
B.To advertise the delicious grilled chickens.
C.To introduce Sila Sutharat's extraordinary gai yang.
D.To help his friend attract more tourists to his restaurant.
