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.

(2013·高考安徽卷，B)Using too much water or throwingrubbish into our rivers are clear ways that humans can put our water supply in danger，but we also affect our water supply in less obvious ways.You may wonder how paving(铺砌) a road can lead to less useable fresh water.A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It comes from underground.The more roads and parking lots we pave，the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺)．Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall，but in any case，good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference，too.In the United States，a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there’s a lot we can do to lower the number.
You can take steps to save water in your home.To start with，use the same glass for your drinking water all day.Wash it only once a day.Run your dishwasher (洗碗机)only when it is full.Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
小题1:Which of the following is most likely to lead to less groundwater?

A．Using river water.

B．Throwing batteries away.

C．Paving parking lots.

D．Throwing rubbish into lakes.

小题2:What can be inferred from the text?

A．All water shortages are due to human behavior.

B．It takes a lot of effort to meet our water needs.

C．There is much we can do to reduce family size.

D．The average family in America makes proper use of water.

小题3:The last paragraph is intended to________.

A．show us how to fix leaks at home

B．tell us how to run a dishwasher

C．prove what drinking glass is best for us

D．suggest what we do to save water at home

小题4:The text is mainly about________.

A．Why paving roads reduces our water

B．how much we depend on water to live

C．why droughts occur more in dry climates

D．how human activity affects our water supply

Most people know that awkward feeling when you walk into an elevator with other people and try not to make eye contact(接触). But a new research suggests it may be down to a subconscious power struggle being played out as you make your way up and down.
A study found that people decide where they stand based on a micro social status，established within seconds of entering the lift.
Rebekah Rousi．a Ph. D．student in cognitive(认知)science，conducted an ethnographic(人种论)
Study of elevator behaviour in two of the tallest office buildings in Adelaide，Australia.As part of her research，she took a total of 30 lift rides in the two buildings，and discovered .There was an established order to where people tended to stand
In a blog she writes that more senior men seemed to direct themselves towards the back of the elevator She said：“In front of them were younger men，and in front of them were women of aII ages.”She also notice there
was a difference in where people directed their gaze(注视)half way through the ride．“Men watched the monitors，looked in the side mirrors(in one building)to see themseIves．And in the door mirrors(of the other building)to also watch others Women would watch the monitors and avoid eye contact with other users(unless in conversation)and the mirrors，”she writes．
She concluded it could be that people who are shyer stand toward the front，where they can’t see other passengers，whereas confident people stand in the back，where they have a view of everyone else.
小题1:The passage is mainly about
A. elevator riding manners
B communication in the elevator
C. elevator riders’ standing positions
D. micro social status in the elevator
小题2:The underlined word“it”in the first paragraph probably refers to“     ”

A．an elevator

B．the new research

C．eye contact

D．social status

小题3:A person who stands in the back of the lift is probably

A smart phone (智能手机) 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 (导航) units to form one multi-use device. Many modern smart phones also include touchscreens and web browsers (浏览器) 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.
小题1:People prefer a smart phone to a common one, because the latter only can help us ______.

A．check emails

B．send messages

C．find the destination

D．watch a video

小题2:The underlined word “obsession” in the third paragraph most probably means “______”.

B．contribution

小题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.

小题4:When the writer mentions the number of people watching the film from mobile devices in the fifth paragraph, he mainly feels ______.

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 (舒适地带) 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.
小题1:Most people can’t be creative geniuses because they _______.

A．don’t have great ideas

B．don’t want to develop their ideas

How can we measure animals’ emotions? A new study of animal’s emotions suggests that, as in humans, emotions can tell animals about how dangerous their world is, and guide the choices that they make. The article of the study by Bristol University’s professor Mike Mendl was published online.
An animal living in an environment where it is often threatened by predators(捕食者）will develop a negative emotion or “mood”, such as anxiety. However, one in an environment with plenty of opportunities to get resources for survival will be in a more positive mood state.
The researchers say that these emotional states not only show the animal’s experiences, but also help it decide how to make choices, especially in unclear situations. This could have good or bad results. An animal in a negative mood state will make a safety-first with a “pessimistic” response to an unclear event. For example, it considers a noise in the grass as a signal of the predator. At the same time, an animal in a positive mood state will benefit from a more “optimistic” response. It considers the noise as a signal of prey(猎物）.
Professor Mike Mendl, head of the Animal Welfare and Behavior Research Group at Bristol University’s School of Clinical Veterinary Science said, “ We can use “optimistic” or “pessimistic”decision-making as a symbol of an animal’s emotional state. Recent studies by our group and others suggest that this is a meritorious new approach to studying a variety of animal species.”
“Public interest in animal welfare remains high, with widespread concern about the way in which animals are treated, used and included in society. To understand how animals should be treated, we need to better understand their emotional lives,” Mike Mendl said. The researchers believe Mike Mendl’s study can help them to better understand and assess an animal’s emotions.

Everyone has got two personalities-the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their positions. The important position is the one that you go to sleep in.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to displease people. So you never express your real feelings. You’re quite shy and you aren’t quite sure of yourself.
If you sleep on your stomach, you are a rather secretive person. You worry a lot and you’re always easily upset. You always stick to your own opinions or judgment, but you don’t raise your hopes too much. You usually live for today not tomorrow. This means that you enjoy having a good time.
If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.
If you sleep on your side, you have usually got a well—balanced personality. You know your strengths and weakness. You’re usually careful. You believe in yourself. You sometimes feel anxious, but you don’t often get sad. You always insist on what you think even if it makes people rather angry.
