Carrots(胡蘿卜) are grown on farms and in small family gardens all over the world. They are easy to plant and easy to harvest(收獲). They have a good taste.
When people think about carrots, they usually think they are a kind of long, thin, orange-colored vegetable. In fact, carrots are in many different sizes and shapes. And not all carrots are orange.
Carrots should be grown in a field that does not have water for a long time. The earth also should not be too hard. To prepare your carrot garden, dig up the earth and turn it over(翻土). 
Weather, soil condition(土壤狀況), and time affect(影響) the taste of carrots. Warm days and cool nights are the best time to grow great delicious carrots.
The best way to decide if a carrot is ready to be harvested is by its color. Usually, the brighter the color is, the better the taste is.
Most people do not know that carrots can be grown during the winter months. If the winter is not cold enough to freeze the ground, you can grow carrots the same way as you do during the summer months.
Carrots are prepared and eaten in many different ways. They are cut into thin pieces and cooked with other vegetables or meat. Or, they are washed, and eaten just as they come out of the ground.
小題1:Carrots are easy to plant but hard to harvest.
小題2:Carrots should be grown in a field without water for a long time.
小題3:The best way to decide if a carrot is ready to be harvested is by its size.

If the temperature rises by 5 degrees tomorrow, you will probably take off just one coat. But such a change in the average world temperature would be a serious problem. Many animals and plants would not be able to deal with these changes, and would die.
The UNEP(聯(lián)合國(guó)環(huán)境規(guī)劃署) released(發(fā)布)the Report 2012 on November 21, 2012. It says that if we don’t take action now, the world temperature will have risen by 3 to 5 degrees by the end of this century.
A large rise in temperatures could be terrible for us and for many other living things on Earth. Sea levels will rise because higher temperatures will cause melting ice flow into the sea.Large coastal (沿海的) cities in countries such as the Netherlands and Bangladesh could be flooded.
Some plants such as corn and sugarcane (甘蔗) will not grow well in higher temperatures. Some countries, such as Brazil and parts of Africa, will not have enough food. The change may cause less rain and even make some places very dry.
On November 26, people from around 200 nations and regions gathered again in Doha (多哈) for the annual UN climate talks.“Climate change is coming to all human beings and effective actions need to be taken to deal with it.”president of the conference said at the opening ceremony.

"Earworms", some people call them. Songs that get stuck in your head go round and round, sometimes for days, sometimes for months. For no clear reason you cannot help yourself from humming or singing a tune by Lady Gaga.
To a psychologist, the most interesting thing about earworms is that they show a part of our mind that is clearly outside of our control. Earworms arrive without permission and refuse to leave when we tell them to. They are parasites (寄生蟲) living in a part of our minds.
If you have got an earworm you can suffer an attack of it simply by someone mentioning the tune, without having to hear it. This proves that earworms are a part of long-term memory. Humans have an "inner ear", for remembering phone numbers, for instance. When it gets infected with earworms, rather than review our plans for the day, or lists of things to remember, the inner ear gets stuck on a few short bars of music or a couple of phrases from a song. A part of us that we normally do not have to think about, that should just do what we ask, has been turned against us, upsetting us with a request that we never asked for. The mind is an inner world which we do not have complete knowledge of, or have control over.
Fortunately psychology can provide some advice on how to deal with an uncontrollable mind. Consider the famous "don’t think of a white bear" problem, which tells you to try not to think about white bears, or to do something else, to avoid both thinking of the white bear and not thinking of the white bear. For earworms, the solution may be the same. Our inner ear has become infected with an earworm. This is a part not under our control, so just sending in instructions to "shut up" is unlikely to be of much help (and has been shown to make it worse). Much better is to employ the inner ear in another task. If your mind is poisoned by Brittany Spears’ Toxic, for instance, then try singing Kylie Minogue’s Can’t Get You out Of My Head. Let me know if it works!
小題1:According to the passage, earworms are ______.
A.songs that keep going round in our mind
B.worms that live in a part of our brain
C.tunes by pop singers like Lady Gaga
D.parasites clearly under our control
小題2:Which of the following statements is TRUE?
A.Singing songs may get earworms out of your head.
B.Earworms are used for keeping long-term memory.
C.Humans do not have complete control over their mind.
D.You won’t suffer from earworms unless you hear the song.
小題3:What does “it” in the last paragraph refer to?
A.The instruction to shut up your mind.
B.“Don’t think of the white bear” problem.
C.Kylie Minogue’s Can’t Get You out Of My Head.
D.Using the earworm-infected inner ear in another task.
小題4:What is the passage mainly about?
A.The causes and influences of earworms.
B.What earworms are and how to deal with them.
C.How to clear earworms out of your head.
D.The relation between earworms and popular songs.
