If women are mercilessly exploited（剥削）year after year,they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion,they are always taken advantage of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it,only a woman is capable of standing in front of a wardrobe（衣橱）packed full of clothes and announcing sadly that she has nothing to wear.

    Changing fashions are nothing more than the intentional creation of waste.Many women spend vast sums of money each year to replace clothes that have hardly been worn.Women who cannot afford to throw away clothing in this way,waste hours of their time altering（政变）the dresses they have.Skirts are lengthened or shortened;neck-line are lowered or raised,and so on.

    No one can claim that the fashion industry contributes anything really important to society.Fashion designers are rarely concerned with vital things like warmth,comfort and durability（耐用）.They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort,as long as they look right.There can hardly be a man who hasn't at some times in his life smiled at the sight of a woman shaking in a thin dress on a winter day,or delicately picking her way through deep snow in high-heeled shoes.

    When comparing men and women in the matter of fashion,the conclusions to be drawn are obvious.Do the constantly changing fashions of women's clothes,one wonders,reflect basic qualities of inconstancy and instability （不稳定）?Men are too clever to let themselves be cheated by fashion designers.Do their unchanging styles of dress reflect basic qualities of stability and reliability（可靠）?That is for you to decide.

    It is easier to float in the ocean than it is to float in a swimming pool.Do you know why?

    Ocean water is full of salt--and salt water can hold up more weight than fresh water.See for yourself!

You will Need:

3 cups of warm water

Measuring cup(量杯)

Wide-mouthed jar

Salt

Spoon

Raw(生的)potato

You Will Do:

⒈Pour 1.5cups of warm water into the jar.

⒉Add 1/3 cup of salt.

⒊Stir(搅拌) until the salt is completely dissolved.

⒋Add another 1.5 cups of water.Pour it slowly over the back of the spoon into the jar so that the two liquids will not mix together.

⒌Gently place the potato into the jar.Do not drop it.

    What Will Happen:

    The potato will sink--but only halfway!

    Why?

    Salt water is heavier than fresh water,so it will stay on the bottom.The fresh water will remain on top.

    The potato is heavier than the fresh water,but it is lighter than the salt water.That is why the potato will sink halfway down.

    Smartphones, tablets and laptops make it easy for people to work on the go, but traditionally, printers have been cumbersome to move out of the office. However, the new Zuta Pocket Printer will enable people to print anywhere. The Zuta Pocket Printer was invented by Zuta Labs, based in Jerusalem. This small printer is about 10.2 cm wide and long and 7.5 cm high, and weighs about 350 grams. The company plans to ship its printers to customers in the beginning of 2017.

    This printer can connect wirelessly to smart phones, tablets, laptops and PCs via Wi-Fi, and is supported by Android, iOS, OS X and Windows. A free application from the company lets you use the printer via a mobile appliance; a laptop or PC can also select the printer for Use just like any other wirelessly connected printer. This printer can print one average A4 page, measuring 21 by 29.7 cm. Zuta Labs noted that its printer can print on any standard size piece of paper, and that, in principle, it could print on any surface.

    The printer's," omni-wheels" help it turn and move in any direction on a surface. Laser sensors（激光传感器）help control the movement, speed and location, according to the company.

    Zuta Labs said the printer's rechargeable battery can last about l hour, on average—long enough to print about 60 pages. One ink cartridge（墨盒）can print more than 100 pages, according to the company. Currently, the appliance prints only in black, although Zuta Labs said it plans to have a full-color printer in the future.

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces,” said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    “This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    You know the feeling that you have left your phone at home and feel anxious, as if you have lost your connection to the world. “Nomophobia” (无手机恐惧症) affects teenagers and adults alike. You can even do an online test to see if you have it. Last week, researchers from Hong Kong warned that nomophobia is infecting everyone. Their study found that people who use their phones to store, share and access personal memories suffer most. When users were asked to describe how they felt about their phones, words such as “hurt” (neck pain was often reported) and “alone” predicted higher levels of nomophobia.

    “The findings of our study suggest that users regard smartphones as their extended selves and get attached to the devices,” said Dr. Kim Ki Joon. “People experience feelings of anxiety and unpleasantness when separated from their phones.” Meanwhile, an American study shows that smartphone separation can lead to an increase in heart rate and blood pressure.

    So can being without your phone really give you separation anxiety? Professor Mark Griffiths, psychologist and director of the International Gaming Research Unit at Nottingham Trent University, says it is what is on the phone that counts-the social networking that creates Fomo (fear of missing out).

    “We are talking about an internet-connected device that allows people to deal with lots of aspects of their lives,” says Griffiths. “You would have to surgically remove a phone from a teenager because their whole life is rooted in this device.”

Griffiths thinks attachment theory, where we develop emotional dependency on the phone because it holds details of our lives, is a small part of nomophobia. For “screenagers”, it is Fomo that creates the most separation anxiety. If they can't see what's happening on Snapchat or Instagram, they become panic-stricken about not knowing what's going on socially. “But they adapt very quickly if you take them on holiday and there's no internet,” says Griffiths.
