3 . A working semiconductor (半导体) has been created from graphene(石墨烯), potentially laying the foundation for a new type of computer with greater speed and efficiency than today’s silicon chips(硅基芯片) allow.

Graphene, a material made from a single layer of carbon atoms, is a good electrical conductor resistant to heat and acids. But a working graphene semiconductor which can be controlled to conduct or separate electricity at will, has evaded scientists. Such semiconductors are key to creating the logic chips that power computers.

The problem has been the lack of what is known as a bandgap. Semiconductors have bands of higher and lower energies and a point—the bandgap—at which excited electrons can jump from one to the other. This effectively allows the flow of current to be switched on and off, so it is either conducting or not conducting, creating the binary system of zeroes and ones used in digital computers.

Now, Walter de Heer at the Georgia Institute of Technology and his colleagues have created graphene with a bandgap and demonstrated a working transistor, an on/off switch that either prevents or allows current to flow through it. De Heer said the electrical properties of a graphene semiconductor were far better than those of silicon chips. “It’s like driving on a rocky road versus driving on a freeway,” he said.

Silicon chips are cheap to make and backed by extensive production facilities, but we are reaching their limits. Moore’s law states the number of transistors in a circuit will double roughly every two years, but the rate of downsizing has slowed recently as engineers reach circuit concentration beyond which electrons can’t be reliably controlled.

“You can use all the technology the whole semiconductor industry is totally comfortable with to scale up this process,” says David Carey at the University of Surrey, UK. But he suspects the world will soon shift to graphene chips, because silicon has such a head start. “Most people working on silicon are bombed daily by new, wonderful materials that are about to replace it and none of it’s ever happened,” he says.

6 . Getting and staying focused can be a challenge even in the best of times. But with everything going on in the world, concentrating can often feel down-right impossible. Below are some tips to help you find your flow.

Distract (使分心) your brain. Schedule into every workday some breaks from all that focusing and allow your mind to travel into what’s called the “default (默认的) mode network” for a bit of freestyle activities.     1    . It’s the place where our minds find innovation and creativity and often make better decisions than the focused mind.

    2    . This involves first turning your attention inward. Try traveling with your mind to someplace enjoyable — maybe it’s a walk through an imaginary forest or sunbathing on a warm sandy beach. Doing this several times a day can offer your mind a fresh approach to the job at hand.

Block interruptions before diving into deep work.     3    . To help, turn off text messaging, notifications and social media alerts. Be vital when you want a deep dive into focus. Your important work benefits when you shut off or put away your phone and other screens.

Know your body clock. Whether you are sharp in the morning or a night owl, don’t spend your day — in particular your peak brain hours — doing busywork.     4    .

Try new hobbies. Engaging in hobbies not only is fun but can help us come up with new solutions to problems we’re facing at work or home.     5    .

A．Try to daydream what happened

B．We try to obtain focus but in vain

C．Engage in positive constructive daydreaming

D．Instead, reserve your best brain time for the big stuff

E．This network of the brain circuit is where magic happens

F．Our days are filled with distractions, from others and ourselves

G．Allowing your mind time to play is another way to invite innovation

7 . As a kid, I was always around animals and I always enjoyed it. After my senior year of high school, we started renting this farm. Then I went away to Rhode Island School of Design to become an architect. After about two years and a half, I found that was not quite what I wanted to do. I felt I wanted to be an architect and have a hobby farm. But why not just have a farm and make it my career?

It’s an exciting business. I think a lot of people don’t realize what’s involved with dairy farming (奶牛业). We took some trips to some progressive farms out in New York when we first started. And it really changed my attitude of what you can do. You can be a successful businessperson with a lot of challenges. And those challenges are part of what makes it very exciting — it’s not just milking cows. There’s nutrition and finances and a lot of big day-to-day decisions.

Well, land is the biggest obstacle. Securing enough land is important. We don’t just need the land for the animals; we also need it to distribute the manure from the cows. And there’s a real balance, a real recycling. You take the feed; you give it to the cows, and the cows give you milk, but they also give you a lot of manure. And the best thing to do is putting it back on the land. You need 2 acres per cow basically, a cow and its calf.

The land that we rent is beautiful and the land that we own is beautiful. If you get half a mile off the road and looking back at scenery across the valley, it’s impressive. You get the rows of grass and the cows in the distance.

1. Which of the following is included in the dairy farming according to the text?

A．Designing for the dairy farming.

D．Milking cows, nutrition, finances and decisions.

2. What’s the biggest challenge that the author faced?

A．Huge amounts of money.	B．Securing enough land.
C．Highly qualified milk cows.	D．Quantities of workers.

3. What’s the meaning of the underlined word in Paragraph 3?

A．Milk from the cows.	B．Chemical fertilizers.
C．Waste of the cows.	D．Food offered to cows.

4. Which one is the best title for this text?

A．Building a Successful Dairy Business

B．Famous Farmers Around the World

C．Highly Qualified Milk Cows

D．The Architecture Designer
