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2:The following can be used as organic materials to make mulch EXCEPT________.
A.tree barksB.cut­up leaves

小題3:Which of the following is the benefit of mulch?
A.Protecting the soil against wind and water damage.
B.Keeping the soil wet and reducing the need for watering plants.
C.Reducing temperature changes in the soil and stopping unwanted weeds
growing.
D.All of the above.
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
小題5:From the last paragraph, we know ________.
A.the best time to add mulch is in spring and summer
B.the best time to add mulch is after the coldest weather arrives
C.the best time to add mulch depends on weather
D.choosing the best time to add mulch can avoid attracting small animals

(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(鋪砌) 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 (洗碗機)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.
小題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.
小題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.
小題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
小題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

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

A.creative thinkingB.the muscleC.personal styleD.great capacity
小題3:What do we learn from the passage?
A.No computer can store as much information as human’s brain.
B.It is not necessary to remember everything around you.
C.Try something new, as long as you are comfortable with it.
D.It is harder to exercise the brain than the muscles
小題4:The passage is intended to tell readers _________.
A.how they can learn from creative geniuses
B.a(chǎn)bout ways to develop their creative thinking

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(獵物).
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.
小題1:When an animal is in a negative mood state, _______.
A.its response to an unclear event is pessimistic
B.it will pay little attention to an unclear event
C.it is easy for it to make right decisions
D.it has more opportunities to get food
小題2:The underlined word “meritorious” in Paragraph 4 can be replaced by “_______”.
A.valuableB.uselessC.fashionableD.hopeless
小題3:We can infer from the passage that ________.
A.the animals with positive emotions live longer
B.there is no way to assess an animal’s emotions
C.few people care about animal welfare nowadays
D.the environment can influence animal’s emotions
小題4:Mike Mendl advised people to better understand animal’s emotions in order to _____.
A.tell people to build more protected areas for animals
B.explain animals should be regarded as people’s friends
C.raise people’s interest in studying animals
D.make people know how to treat animals properly
小題5:What would be the best title for the passage?

B.Emotions Helps Animals to Make Choice
C.The Living Environment of Wild Animals

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.
小題1:According to the passage, a person, who is not willing to change his mind and hard to deal with, probably sleeps           .
A.on his sideB.on his backC.curled upD.on his stomach
小題2:If a person prefers to sleep curled up rather than on his back, he may be well content to    .
A.do things personally.B.stay alone
C.keep things secretD.trust others easily
小題3:Which of the following people, in the author’s opinion, most likely have personalities opposite to each other ?
A.The people sleeping on their stomachs and those sleeping on his backs.
B.The people sleeping on their sides and those sleeping curled up.
C.The people sleeping on their backs and those sleeping on their sides.
D.The people sleeping curled up and those sleeping on their stomach.
小題4:What the author mainly intends to tell us is that            .
A.one’s sleeping position has something to do with one’s character.
B.everyone has got both real and secret personalities.
C.the position in which one goes to sleep is the most important one.
D.when awake, one does not show one’s secret personality.
