Think twice before using money on expensive skin care products . The best way to keep your skin in good condition is enough sleep. Third, pay attention to your daily things.

Take the dishes that haven't been eaten up away for next day when you have dinner in a restaurant. When it's your turn to offer a meal, invite your friends to your home, and cook the dinner yourself.

Read the article and select the best answer. Article: Sales of electric bicycles, or e-bikes, a hot item in consumer green tech, are expected to grow by more than 50% in North America during 2013. Actor William Shatner, who is no stranger to futuristic tech, recently purchased two e-bikes for him and his wife. I've been shopping for an e-bike now for a few weeks, and I've had my eye on the folding electric bike. I've had folding bikes in the past and love the convenience of being able to throw my bike into my car. The e -bike market is ready to go mainstream in the U.S. The price for e-bikes has come down greatly in recent months. At one time, most e-bikes with good components and proper weight were in the $3,000range. Now you can find reasonable quality e-bikes in the $1,000range. With gas prices at all-time highs, e-bikes are an attractive, low-cost option to gas efficient vehicles. E-bike owners are finding that they are great for commuting to work, as traditional bikes can be a problem with office dress and sweat. People who use e-bikes range from commuters to casual cyclers who like a little help with hills and wind,to those who decided to save money on buying a motor bike.These are not for the serious road cycler or professional mountain biker. If you're considering all e--bike, it pays to do some research first.Cheaper e-bikes are going to be heavier and have less battery--power.Higher priced bikes will be made from lighter materials and have better batteries. Another consideration is local motor vehicle laws.For example,according to US federal law,as long as your electric bike is under 750 watts and does not go over 20 MPH then it is a bicycle and not a motor vehicle.Most consumer e--bikes in the $1,000 range don't fit the motorized vehicle description. Question: What is the best title for this passage? Options: A: E--bike sales to shift into mainstream in 20l3 B: E-bikes,the future way of transportation C: E--bikes Vs gas vehicles D: E--bikes,actors' first choice

Q: Read the article and select the best answer. Article: The card using a built-in voice-recognition chip requires users to give a spoken password that it recognizes. The idea is to prevent thieves from using a stolen card to buy goods online. A model built by engineers in California packs a microphone, a loudspeaker, a battery and a voice-recognition chip into a standard-sized credit card. The card is the length and width of an ordinary credit card but about three times as thick. The company now plans to make it thinner. The voice card is based on an earlier Beep card technology designed to prevent fraud in online deals. The Beep card has no microphone, but has a built-in loudspeaker to utter an audible ID signal by a computer's microphone to an online server . By confirming that signal matches the information in the card, the server can make sure that the user is not simply keying in a credit card number but actually has the card in his hand. The ID code, which only the server knows, changes each time the card is used. This prevents fraudsters recording the beeps, noting the card details and then playing back the audible ID when they key in the details later. But this earlier Beep card technology cannot prevent illegal use of stolen cards. The new voice card can. The new voice card doesn't identify itself by its ID until it has confirmed the real user's spoken password. Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy. The challenge for Beep card has been to develop voice-recognition and audio circuitry . The voice-recognition credit is powered by a mini battery. To extend batter life, the electronics have only to be switched on when the card is being used. Pressing a button on the card's surface allows one to hear a female voice saying, "Say your password." If the voice-recognition software proves that the password is real, it sends its ID, which the server then identifies, allowing the deal to continue. Question: Why is the voice credit an important innovation? Options: A: It is cheap to make and buy. B: It can leave voice messages. C: It makes online shopping easy. D: It makes fraud more difficult.
A: D
