People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

Mulch is a protective cover of material that is spread on top of soil.It is usually made out of organic material, like crop waste.Farmers may keep the remains of maize or other crops on top of the soil.This creates mulch on the soil surface.The plant remains help protect the soil against wind and water damage.Mulching is one of the best things people can do for their plants.It also helps keep the soil from getting dry, and reduces the need for watering plants.It also limits temperature changes in the soil.And it stops unwanted plants, or weeds,from growing.
Organic mulch improves the condition of soil.As the mulch breaks down, it provides material which keeps the soil from getting hard.This improves the growth of roots and increases the movement of water through the soil.It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants.It also provides a good environment for earthworms and other helpful organisms in the soil.
It is easy to find organic mulch materials.Cut­up leaves and small pieces of tree bark can be used.Grass cuttings are also a good mulch for plants. Mulch from newspapers works well in controlling weeds.
The best time to add mulch depends on your goal.Mulch provides a thick barrier between the soil and the air.This helps to reduce temperature changes in the soil. As a result,mulched soil will be cooler than other soil in the summer.In winter, the mulched soil may not freeze as deeply as other soil.The best time is after the ground has frozen, but before the coldest weather arrives.Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter.Delaying the spreading should prevent this problem.The animals will probably find another place to live.
小題1:The author tells us the following EXCEPT________.
A.what mulch is and its benefits
B.the best time to add mulch
C.what can be mulched on the soil surface
D.the bad effects of mulch

小題4:The main idea of Paragraph 2 is that organic mulch can________.
A.improve the condition of soil
B.improve the ability of the soil to hold water
C.provide a good environment for earthworms
D.improve the growth of roots and increase the movement of water through the
soil

A wave of recent research has pointed to the risks of over praising a child. And it seems that how to draw a line between too little praise and too much has become a high-pressure _  _act for parents.
Self-esteem (自尊)  serves as a kind of tool to measure how much children feel valued and accepted by     . This sensitivity to others'      develops because of humans' need for social acceptance, which is considered to be      to survival. As early as age 8, children's self-esteem tends to rise and fall in response to feedbacks about      peers see them as likable or attractive.     , it can also be beneficial for kids to feel bad about themselves occasionally, if they behave in selfish, mean or hurtful ways that might      their ability to maintain relationships or hold a job in the future.
In the past, many parents and educators believed that high self-esteem      happiness and success, and kids could gain self-esteem simply by getting      and awards from their parents, teachers and people around. But recently researchers have found self-esteem doesn't  _   these desired results. Instead, if parents praise their kids     , their self-esteem becomes focused on being very smart and being the best and being perfect. Building too much self-esteem of the children can not go as planned, making them feel      later on when they hit setbacks (挫折).
According to some experts, it can actually be good for kids to have      self-esteem, at least once in a while. And praise can be      if it disregards the world outside the home. Children who have a      understanding of how they are seen by others tend to get recovered more readily      disappointment, depression or the like. The best path is a      road, helping children develop a positive but      view of themselves in relation to others by praising them for the      they invest and behaviors they are able to sustain, like "It's      that you're working so hard on your homework.

A kitchen that gives step-by-step cooking instructions in French could inspire a revolution in language learning in the UK. By using a new technology, it speaks to you as you prepare a French dish. The kitchen breaks new ground by taking language learning out of the classroom and linking it with an enjoyable and rewarding real-life activity.
The new kitchen is designed to be used in schools, universities and even people’s homes. It could also be an existing kitchen. The first version of the technology was tested in the kitchens of project partner Newcastle University. The kitchen could be available for schools and universities, and for the UK market by the June of 2014.
The Newcastle University team is now working on ways to put it on the market. And the European Union has given money to begin programs in six other languages, including English Italian and Spanish. Finally, versions could be developed for any language cuisine(烹飪法)in the world.
Professor Paul says, “By international standards, the UK students are now poor when it comes to learning languages—a problem that certainly has an economic influence. We believe that developing skills in a country’s language and its cuisine will help change the trend.”
On a computer fixed into the kitchen, the user first selects the French recipe(菜譜)they want to follow. Digital sensors built into dishes, containers and other equipment then communicate with the computer to make sure the right instructions are given at the right time, the user can ask the computer to repeat an instruction, or translate it into English, simply by pressing the touch screen. After cooking, the user can test what they have learned by carrying out a short test on the computer.
All grammar and vocabulary has been carefully selected to make sure that using the kitchen adds to basic proficiency(熟練)in understanding French.
Now three easy-carrying versions of the kitchen are being prepared. They’re to be fixed in Newcastle University and at Institute Francais, a London-based charity devoted to teaching the French language.
小題1:The new kitchen is designed mainly to __________.
A.increase people’s interest in cooking
B.teach people how to cook French dishes
C.offer people a new way to learn languages
D.help cooks learn spoken French in the kitchen
小題2:Which of the following is TRUE about the kitchen?
A.It has versions in six languages now.
B.It is already available for sale in the UK.
C.It has received strong support from the EU.
D.It can be used only in schools and university.
小題3:When a person is using the kitchen, ___________.
A.it will give him a test on his cooking skills
B.it can translate French into another language
C.the cooking process will stop if he goes wrong
D.he must be careful so as not to make mistakes
小題4:What would be the best title for the text?
A.UK students have problems in language learning.
B.New technology helps students learning cooking.
C.An enjoyable and rewarding real-life activity.
D.A Talking Kitchen That Teaches You French.

A smart phone (智能手機) is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation (導(dǎo)航) units to form one multi-use device. Many modern smart phones also include touchscreens and web browsers (瀏覽器) that display web pages.
A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn’t mean making calls, but playing phone games and browsing the Web.
Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It’s no secret that our lives are being affected by our smart phones obsession.
However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen.
Ironically, YouTube’s data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones.
The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it.
小題1:People prefer a smart phone to a common one, because the latter only can help us ______.
A.check emailsB.send messagesC.find the destinationD.watch a video
小題2:The underlined word “obsession” in the third paragraph most probably means “______”.
A.devotionB.contribution C.a(chǎn)ddictionD.emotion
小題3:Which of the following is right?
A.People spend as average of two hours and 40 minutes each day using smart phones.
B.The film hasn’t been put on in the cinema.
C.The film is written by an actor named Charlene Deguzman.
D.The film has already been viewed more than 105 million times in the first few days.
小題4:When the writer mentions the number of people watching the film from mobile devices in the fifth paragraph, he mainly feels ______.
A.encouraged B.depressedC.proudD.satisfied

You have some great ideas. But they don’t come out because of what your friends say or because you think that only a few people can be creative geniuses(天才). And, you, of course, think that you couldn’t be one of them. But actually, this is not true at all.
Anyone who is a creative genius will tell you that creativity is very much like a muscle that needs to be developed. If you don’t learn how to develop creative thinking, this skill, just like a muscle, will become poor and useless. On the other hand, keep working at it, and this skill will soon be ready for action whenever you need it. So how do you develop your own personal style of creative thinking?
You should realize that your brain has a greater capacity (容量) and a higher speed than the world’s biggest and fastest computer. So it’s important to get as much information as you can every day. Read, watch and listen to everything around you —good and bad. The more you know, the more you’ll want to know, and the more your brain will be exercised.
Try something new every day and let your experiences show you more about the world and people around you. You need to step out of your comfort zone (舒適地帶) more and more each day.
Follow these suggestions, and begin thinking beyond your "limits" from today. You’ll soon have a life full of interesting and exciting adventures. Who knows, your idea might be the next great idea to change the world.
小題1:Most people can’t be creative geniuses because they _______.
A.don’t have great ideas
B.don’t want to develop their ideas
C.a(chǎn)re too shy to talk about their ideas
D.don’t believe they can be

B.It is not necessary to remember everything around you.
C.Try something new, as long as you are comfortable with it.

It’s the dirty little secret many shampoo companies don’t want you to know.  When you wash your hair with certain traditional chemical shampoos, you may actually be removing your hair and scalp(頭皮)of their natural oils.  These shampoos generate a thick bubble to clean hair, they can also create dryness, curl, dullness, and color fade. We then spend a lot of time and money on products that are effectively repairing the damage caused by shampoo.
Chaz Dean got tired of clients leaving his salon raving about their color and the feeling of their hair---brassy(似黃銅的) and dull. He knew the main cause was likely their shampoo, so he started experimenting with various ingredients, including natural herbs and botanicals, that he knew had cleansing(弄干凈)and hydrating (保濕的) properties.
The result was a totally new approach to the way we cleanse our hair.  It’s called WEN® Cleansing Conditioner.  WEN® contains a super-hydrating natural herbs and botanicals mixture of glycerin, chamomile(甘菊), rosemary, calendula, and Cherry bark, which when combined, will both cleanse the hair as well as give shine and softness, even to damaged hair.
WEN® is a 5-in-1 formula(配方) that takes the place of your shampoo, And the most amazing thing about it is that it cleanses without bubble.  Instead, when mixed with water, it creates a smooth bubble for shiny, healthy-looking, manageable results.  The first time you try it certainly feels strange, but the results speak for themselves.
Before being marketed, WEN® went through extensive consumer tests, and the results were impressive.  More than 90 percent of the participants in the studies reported that their hair was more shiny, less frizzy, and had more bounce.
WEN® is recommended for all hair types, and once you start using it, it will become the only cleanser/conditioner you will want to include in your daily routine.
Right now, WEN® is offering an easy way for online shoppers to try the product.  Now you just pay less than $30 and have a 60 day money back guarantee if you are not completely satisfied. Click here to learn more about WEN® and try this revolutionary new approach yourself.
