Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的) tooth grow in its place.
But if a permanent tooth falls out, that’s a problem. There isn’t another one under the gum(齿龈)that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out or need to be pulled, an older person might need dentures.
Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth.
Dentures can cause pains at first and take little time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked（浸泡） in denture solution when not in the mouth.
Dentures are important for the old because, without teeth, it’s hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won’t have any teeth. Try not to make fun of the person because this could cause hurt feelings.
People usually lose their permanent teeth due to periodontal disease（牙周炎）, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren’t strong and healthy, so teeth can get loose and fall out. Older people often have many cavities(洞)that have been filled over the years, and these fillings can weaken over time, leading to more tooth problems.

A．should have a false tooth fixed in its place B．have to put it under your pillow at once

Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a ‘territory’ is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.
Some scientists believe that most of the time bird’s singing is actually________.
A. an expression of happiness B. a way of warning
C. an expression of anger D. a way of greeting
【小题２】What does the underlined word “territory’’ mean?
A. A place where families of other species are not accepted
B. A place where a bird may shout at the top of its voice
C. An area for which birds fight against each other
D. An area which a bird considers to be its own
【小题３】Why do birds keep on singing at nesting season?
A. Because they want to invite more friends
B. Because their singing helps frighten outsiders away
C. Because they want to find outsiders around
D. Because their singing helps get rid of their fears
【小题４】How does the writer explain bird’s singing?
A. By comparing birds with human beings B. By reporting experiment results
C. By describing birds’ daily life D. By telling a bird’s story
Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe（成熟） or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.
The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.
Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and she does not.
1.Greenhorn now refers to ____.
A. a person who is new in a job B. a new solider C. a young horse D. a thumb
2.A person who has a green thumb is a person ____.
A. whose garden is greener than others’ B. whose thumbs are in green color
C. who is good at growing plants D. who is younger than his neighbors
3.The author is actually talking about ____.
A. colors B. language C. politics D. agriculture
4. Which of the following statements is NOT true according to the passage?
A. In about the 16th century, a greenhorn meant an experienced soldier
B. The Green Revolution may have some connection with green thumbs
C. The green-eyed monster was probably created by William Shakespeare
D. The green-eyed monster can be used to describe a person who is jealous
