Whether or not your mouth is moving right now...

Whether or not your mouth is moving right now, you are talking to yourself. As you read these words, your facial muscles are having quick, invisible movements, sounding out the words so you can actually hear them in your head. This kind of speech is called "subvocalization", and unless you're a speed-reader who has trained yourself out of this habit, you're doing it every time you read or even imagine a word.

Now, MIT researchers want to use those subvocalization to know what's in your mind and translate it into digital orders, using a wearable smart headset called AlterEgo. The headset combines human and machine in some ways.

According to the MIT Media Lab, the device would allow users to send silent orders to the headset simply by thinking of a word. A neural (神经的) network would translate the muscle movements to speech and do the user's orders—totally hands-and-voice-free. Let's say you want to ask AlterEgo what time it is. First, you think the word "time". As you do, your facial muscles make micro-movements to sound out the word in your head. Electrodes(电极) on the headset record these movements and then send them to a computer. The neural network processes these signals the same way a speech-to-text program might, and responds by telling you the time.

In a small study, 10 volunteers read a list of numbers to themselves while wearing AlterEgo headsets. AlterEgo correctly got which numbers the participants were reading with an average accuracy of 92 percent. For comparison, Google's microphone-based speech-to-text translation service has an accuracy of about 95 percent.

“We basically can’t live without our digital devices,” said Pattie Maes, an MIT professor. "But at the moment, the use of those devices is causing some problems in our life. My students and I have been experimenting with new types of experience that enable people to still benefit from all the wonderful knowledge and services that these devices provide but do it in a way that lets them remain in the present.”

1.We can learn from the first paragraph that “ subvocalization” _______.

A. is less used in life now

B. is more effective than speed reading

C. refers to a silent way of reading something

D. means reading something in a detailed way

2.What does Paragraph 3 mainly talk about?

Will you stop using plastic?

If you take a look around your kitchen or office right now, chances are that you’ll notice you’re surrounded by plastic—water bottles, to-go coffee cups, straws (吸管), plastic grocery bags, food wrappers, take-out containers, single-serve coffee pods and produce bags. 1.

It’s certainly not realistic to remove all plastic from your life, but let’s examine some statistics that may encourage you to reduce your single-use plastic footprint by throwing away straws, switching to reusable water bottles, bringing cloth bags to the grocery store and more.

According to a study published in the journal Science Advances, the popularity of plastic, which began rising in the 1950s, is growing out of control. 2. And there’s no sign of slowing down, considering scientists say that another 12 trillion kilograms will be produced worldwide by 2050.

“Every piece of plastic that has ever been created will remain in the environment in some form, but once we conveniently throw out our rubbish at home, wind and runoff carry our waste from landfills and streets to the ocean,” says Mystic Aquarium’s chief clinical veterinarian Jennifer Flower, DVM, MS. “Given that we are globally producing over 320 million tons of plastic annually, the marine environment is taking a big hit from our daily disposal of plastic.

3. For example, newborn fish are mistaking tiny bits of plastic waste for food. If they die, there will be fewer big fish—and that could damage the food chain. Often our society is so focused on making our lives more convenient in the short term, but in the long run, our health and the health of marine life are at the expense of those everyday conveniences.”

4. A recent report suggests that when heated, certain food additives (添加剂) can damage hormones, growth and development, as well as increase chances for children of being fat. 5. It is found in plastic containers and metal cans. Parents are urged to avoid using microwaves to warm food and drinks or placing plastics in the dishwasher.

A. Our plastic consumption is directly affecting the life in the ocean.

B. People are concerned about the results of overusing plastic containers.

C. 8.2 trillion kilograms of plastic have been produced around the world.

D. Using plastic containers in microwaves is also harmful to children’s health.

E. Let’s stop using plastic for the benefit of the environment and human beings.

F. These are all examples of single-use plastic products, which is a hot topic nowadays.

G. The most concerning artificial additive BPA is a chemical used in the production of plastics.

Could your cellphone give you cancer? Whether it could or not，some people are worrying about the possibility that phones，powerlines and wi-fi could be responsible for a range of illnesses，from rashes to brain tumors.

For example，Camilla Rees，48，a former investment banker in the US，moved out of her apartment in San Francisco because of the radiation coming from next door．Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly．“I would wake up dizzy in the morning．I’d fall to the floor．I had to leave to escape that nightmare，” she saiD． Since then，she’s been on a campaign against low-level electromagnetic fields，or EMFs（低频电磁场）.

And she’s not alone．Millions of people say they suffer from headaches，depression，nausea and rashes when they’re too close to cellphones or other sources of EMFs.

Although the World Health Organization has officially declared that EMFs seem to pose little threat，governments are still concerneD． In fact，last April，the European Parliament called for countries to take steps to reduce exposure to EMFs．The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones.

If these fears are reasonable，then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots.

Some say there is evidence to support the growing anxieties．David Carpenter，a professor of environmental health sciences at the University at Albany，in New York，thinks there’s a greater than 95% chance that power lines can cause childhood leukemiA． Also there’s a greater than 90% chance that cellphones can cause brain tumors.

But others believe these concerns are unreasonable paranoia (猜疑)．Dr．Martha Linet，the head of radiation epidemiology at the US National Cancer Institute，has looked at the same research as Carpenter but has reached a different conclusion．“I don’t support warning labels for cellphones，” said Linet．“We don’t have the evidence that there’s much danger.”

Studies so far suggest a weak connection between EMFs and illness — so weak that it might not exist at all．A multinational investigation of cellphones and brain cancer，in 13 countries outside the US，has been underway for several years．It’s funded in part by the European Union，in part by a cellphone industry group．

According to Robert Park，a professor of physics at the University of Maryland in the US，the magnetic waves aren’t nearly powerful enough to break apart DNA，which is now known threats，such as UV rays and X-rays，cause cancer.

Perhaps it’s just psychological．Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome，which is a condition that’s considered to be psychological.

Whether EMFs are harmful or not，a break in the countryside，without the cellphone，would probably be good for all of us.

Cell phones:　 is there a cancer link?

Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.

Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ” said Carpenter.

But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ” said Linet. “We don’t have the evidence that there’s much danger. ”

Studies so far suggest a weak connection between EMFs(电磁场) and illness— so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.

1.From the passage we can learn that some people are worried because _______.

A. they have evidence that the use of cell phones can lead to cancer

B. they make a fuss over cell phone use

C. some experts have given a warning

D. cell phones are responsible for brain tumors

2.By saying “I don’t support warning labels for cell phones, ” Dr Martha Linet has the idea that _______.

A. the worrying is unnecessary

B. cancer-warning labels should be on cell phones

C. there is a link between cell phones and cancer

D. cell phones have nothing to do with cancer

3.Which of the following best describes the attitude of the author towards the debate?
