Facebook to buy tech start-up working on mind control technology
TECH giant Facebook announced it has made a deal with a start-up company working on technology that will allow users to make computer commands using their mind 1. of more traditional methods like taps and keystrokes.
CTRL-Labs will become part of Facebook Reality Labs with an aim of perfecting the technology and 2. (build) it into consumer products, according to Andrew Bosworth, vice president of augmented reality and virtual reality at the social media company. “We spend a lot of time trying to get our technology 3. (do) what we want rather than enjoying the people around us. We know there are more natural, intuitive ways to interact with devices and technology,” he said in 4. online post.
The wristband will decode electrical impulses 5. (send) to hand muscles, telling them to move in certain ways. The vision for this work is a wristband 6. lets people control their devices as a natural extension of movement. Here’s how it 7. (work): You have neurons in your spinal cord that send electrical signals to your hand muscles telling them to move in specific ways such as to click a mouse or press a button.
The wristband will decode those signals and translate them into a digital signal your device 8. understand, empowering you with control over your digital life. It captures your intention so you can share a photo with a friend using an unperceivable movement or just by, well, intending to. Bosworth also explains how thought-commanded interactions might dramatically alter 9. people experience virtual reality scenarios, which currently feature hand-held controls. 10. Facebook hasn’t disclosed financial terms of the deal to buy the New York-based CTRL-labs so far, unconfirmed media reports said it paid more than $500 million.

Do you believe love is the most important? In the early twenty century, homeless people were often brought up in orphanages, in that they received little love. At one time, Dr. Skeels took twelve children from an art orphanage or had a young girl look them each day. He also studied another the twelve children who are left in the orphanage all day long. He followed these children until they grew up, and the results were shocked. The children staying all day in the orphanage were either dead or suffering from serious illnesses. However, the twelve children loved by the girl were all healthy and independently. The only differences between these children -- the love, made a great difference to us.
For me personally, I could write for days about many different situations where adversity (逆境)______ my life. Now let me tell you one experience where I almost let adversity ______.
We had a glass studio, which was located 50 feet from our home. A couple of years ago we experienced an _____ winter; we had a lot of snow and ice. The ____ of the ice and snow______ the roof on our studio, taking with it one of our sources of income. ______ it did fall down, we got on the roof and tried to ____ the snow and ice, but when you have 5 feet of ice and temperatures of minus 20 Celsius, it was pretty ______ to do.
We had a partner come in to help us try to ______ the roof by supporting. In the end, there was ______ that could be done. The roof came down. We had moved a lot of our goods and tools from the studio ______ we lost a lot also: glass, kilns, workbenches, to name only a few of the items. It was a ______ experience.
Here we were in the middle of winter with our studio collapsed. We couldn't work as we had almost______ all the material in a building we were not using. We could have done one of two things: we could simply say that we can no longer _____ our glass business. Let me tell you that this was certainly a thought that ______ our mind. Or we could find a way to get our studio back up and running.
We picked the _______ option. We had a large barn that we were not using. So we renovated (翻新) the barn, _____ our working area and today we have a nicer studio than we ______ had. If the adversity we were ______ had not happened, we probably would ______ be working in the old studio — a studio that was less efficient.

Recently, I’ve been following a simple rule that is helping me crush procrastination(拖延症) and making it easier for me to stick to good habits at the same time．1. There are two parts to the 2-Minute Rule.
Part 1—If it takes less than two minutes，then do it now．
2. For example，washing your dishes immediately after your meal，tossing the laundry in the washing machine，taking out the garbage，sending that email，and so on．
If a task takes less than two minutes to complete，then follow the rule and do it right now．
Part 2—When you start a new habit，it should take less than two minutes to do．
Can all of your goals be accomplished in less than two minutes? Obviously not．But，every goal can be started in 2 minutes or less．3.
It might sound like this strategy is too basic for grand life goals，but I beg to differ．The 2-Minute Rule works for big goals as well as small goals because of the inertia(惯性)of life．4. I love the 2-Minute Rule because it embraces the idea that all sorts of good things happen once you get started．
The most important part of any new habit is getting started—not just the first time，but each time．It’s not about performance，it’s about consistently taking action．
I can’t guarantee whether or not the 2-Minute Rule will work for you．5. Anyone can spare the next 120 seconds．Use this time to get one thing done．Go．
A. I call this little strategy the “2-Minute Rule”．
B. And that’s the purpose behind this little rule．
C. Here’s what you need to know to stop procrastinating．
D. Once you start doing something，it’s easier to continue doing it．
E. But，I can guarantee that it will never work if you never try it．
F. The goal is to make it easier for you to get started on the things you should be doing．
G. It’s surprising how many things we put off that we could get done in two minutes or less．
Scientists have created a scent(气味)-delivery system that releases a pleasant fragrance when you sweat. Apply it to your skin, and the more you sweat, the better you’ll smell. That’s because the perfume only gets released upon contact with moisture(湿气).
Chemists from Harvard University combined two compounds(化合物) to create their new system. One chemical is alcohol-based. This is the nice-smelling perfume. The other chemical is an ionic liquid(离子性液体), which is a type of salt that is liquid at room temperature. Ionic liquids are made of ions---molecules that have lost or gained one or more electrons. If the molecule loses electrons, it will have a positive charge. If it gains electrons, it gets a negative charge. Ionic liquids contain the same number of positive and negative ions, which makes them neutral(中性的), with no overall electric charge. In general, ionic liquids have no smell.
When the perfume and ionic liquid are mixed together, a chemical reaction occurs. This bonds the molecules to each other. The reaction also temporarily inactivates(使不活跃) the perfume’s molecules. So when applied to the skin, the new perfume has no scent in the beginning. But adding water or sweat breaks the bond between the molecules. That releases the scent into the air.
“The rate of the release of the fragrance depends on how much you sweat, in other words, how much water is available,” explains chemist Nimal Gunaratne from Harvard University, who led the research. “Sweat is like the command to let the fragrance go.”
Christian Quellet is a chemist who has worked in the perfume industry for a long time. He is now an independent consultant based in Switzerland. “Gunaratne’s perfume opens the door to new developments and applications of fragrance controlled-release systems,” he says. Controlled-release systems allow small quantities of some compounds that they hold to enter the environment slowly.
The system also traps some chemicals in sweat that are responsible for the bad sweat smell. These compounds are called thiols (硫醇). Just as water does, thiols break apart the bond that ties the perfume to the ionic liquid. When this happens, the thiols attach to the ionic liquid and their bad scent is inactivated as the perfume had been. This means the water in sweat and its thiols are both able to release the fragrance from the newly developed perfume.
1.Which of the following makes the scent delivery system special?
A.When it releases scent can be well controlled.
B.No perfume is required in the system.
C.The scent can last for a long time.
D.Sweat can help release the scent.
2.The scent is released into the air when ________.
A.the perfume comes into contact with the skin
B.the perfume and ionic liquid contact each other
C.the perfume’s molecules are inactivated by water
D.sweat activates the molecules of the perfume in the mixture
3.What Nimal Gunaratne says in Paragraph 4 suggests that with this scent-delivery system _____.
A.the more you sweat, the better you will smell
B.the perfume can’t always cover the bad smell.
C.how much water is available doesn’t matter much
D.how you smell depends on how much perfume you use
4.What is Christian Quellet’s attitude towards Gunaratne’s new perfume?
A.Indifferent. B.Favorable. C.Doubtful. D.Critical.
