Some plants get so hungry they eat flies, spiders, and even small frogs. What’s more amazing is that these plants occur naturally (in special environment) in every state. In fact, they’re found on every continent except Antarctica.
You’ve probably seen a Venus’ flytrap. It’s often sold in museum gift stores, department stores, and even supermarkets. A small plant, it grows 6 to 8 inches tall in a container. At the end of its stalks（茎）are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger(触发) hairs. When an insect lands on them, the trap suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus’ flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society’s Newsletter. Note: Despite any science –fiction stories you might have read, no meat-eating plant does any danger to humans.
Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following: “attract, kill, digest, and absorb” some forms of insects, including flies, butterflies, and moths. Meat-eating plants look and act like other green plants ---well, most of the time.
All green plants make sugar through a process called photosynthesis(光合作用). Plants use the sugar to make food. What makes “meat-eating” plants different is their bug-catching leaves. They need insects for one reason: nitrogen(氮). Nitrogen is a nutrient that they can’t obtain any other way. Why almost all green plants on our planet get nitrogen from the soil “Meat-eating” plants can’t. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity(酸度). So they’ve come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to “meat-eating” plants. Never fertilize(施肥)them! But don’t worry, either, if they never seem to catch any insects. They can survive, but they’ll grow very slowly.

举一反三
Slow parenting means parenting children in the contact of nature without any interference (干预) of materialistic influence. We can also term it as “self-raising”. In slow parenting children are allowed to do what they think proper and parents just keep a watch over the child. Curiosity of the child leads to exploring and discovering things. Parents provide little help only when it’s too necessary, otherwise keep themselves away from the child and just have a look on him/her: This brings about a feeling of self-dependency and they are encouraged to solve their problems.
This is a natural way of learning. When a child is left to learn in a natural environment, the child’s natural development takes place. Influence of any materialistic way doesn’t let the mind develop naturally. Watching TV, playing video games or joining classes of dance, swimming or any other sports will not let the mind develop naturally.
Here creativity of their mind is developed. They explore ideas. The logic behind this is that the kids of animals learn by nature, so can our kids. So let our children play in the garden, to watch flowers, plants, birds, butterflies and other gifts of nature. In the classes of dance, swimming etc. their creativity is influenced and their natural creativity is suppressed (压制). In these classes they are overburdened and can’t train their creativity. So let them play in the open air or garden without any burden instead of joining classes.
Generally parents give toys to their children and explain how to operate them. But those parents who believe in slow parenting give toys and observe how the children are managing them. Their skill to learn and understand comes out. Maybe the process is slow, but it will be their exploration, which will make them self-dependent, and self-capable to learn.
小题1:In slow parenting, parents ______. | A．set limits to what their children do | | B．keep a close watch over their children | | C．give the whole directions to what their children do | | D．give their children freedom to do what they think proper |
小题2: What is the main advantage of slow parenting according to the passage?| A．Arousing children’s curiosity. | | B．Helping children to be independent. | | C．Making children interested in exploring nature. | | D．Keeping children away from materialistic influence. |
小题3:We can infer from the third paragraph that______.| A．children should join some classes | | B．slow parenting should be done in a logical way | | C．exploring nature is a good way of slow parenting | | D．children can’t learn by nature like the kids of animals |
小题4:What is the passage mainly about?| A．Slow parenting and its advantages. | B．Different parenting styles. | | C．The requirements of slow parenting. | D．The author’s opinion on slow parenting. |

Throughout history, people have been interested in knowing how language first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 years ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even die out completely. About 1,000 years ago English was a little -known relative of German spoken on one of the borders（边界）of Europe.
If a language has a lot of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China cannot understand speakers from other parts.
小题1:The first paragraph mainly tells us that_______.| A．most people in the world speak Chinese | | B．there are thousands of languages in the world today | | C．man has much knowledge about languages | | D．some people know several languages |
小题2:Many European and Indian languages ______.| A．will soon die out completely | | B．were once a relative of English | | C．are the same as before | | D．come from the same family |
小题3:____ seems to have changed a lot| A．Chinese | B．English | C．Spanish | D．German |
小题4: The best title of this passage is .| A．English | B．Changes of English | | C．Chinese | D．Knowledge of Language |

Sometimes people add to what they say even when they don’t talk. Gestures are the “silent language” of every culture. We point a finger or move another part of the body to show what we want to say．It is important to know the body language of every country or we may be misunderstood.
In the United States，people greet each other with a handshake in a formal introduction．The handshake must be firm．If the handshake is weak，it is a sign of weakness or unfriendliness．Friends may place a hand on the other’s arm or shoulder．Some people，usually women，greet a friend with a hug（拥抱）．
Space is important to Americans．When two people talk to each other，they usually stand about two and a half feet away and at an angle，so they are not facing each other directly．Americans get uncomfortable when a person stands too close．They will move back to have their space．If Americans touch another person by accident，they say “Pardon me” or “Excuse me”．
Americans like to look at the other person in the eyes when they are talking．If you don’t do so，it means you are bored，hiding something，or are not interested．But when you stare at someone，it is not polite．
For Americans，thumbs-up means yes，very good，or well done．Thumbs-down means the opposite．To call a waiter，raise one hand to head level or above．To show you want the check，make a movement with your hands as if you are signing a piece of paper．It is all right to point at things but not at people with the hand and index finger（食指）．Americans shake their index finger at children when they scold them and pat them on the head when they admire them．
Learning a culture’s body language is sometimes confusing（使糊涂的）．If you don’t know what to do，the safest thing to do is to smile．
小题1:From the first paragraph we can learn that ________．| A．gestures don’t mean anything while talking | | B．gestures can help us to express ourselves | | C．we can learn a language well without body language | | D．only American people can use gestures |
小题2:If you are introduced to a stranger from the USA，you should _______．| A．greet him with a hug | | B．place a hand on his shoulder | | C．shake his hand firmly | | D．shake his hand weakly |
小题3:In the United States，people often ________．| A．show their friendship by touching each other | | B．show their friendship by glancing at each other | | C．say “Pardon me” to each other when they are talking | | D．get uncomfortable when you stand close to them |
小题4:If you talk with an American friend，it’s polite to ________．| A．look up and down at your friend | | B．look at the other person in the eyes | | C．hide your opinion | | D．look at your watch now and then |
