Directions: Read the following text and choose the most suitable heading from A-F for each paragraph．There is one extra heading which you do not need.

A．Causes of overusing fluoride	B．Negative effects of fluoride
C．Safe use of fluoride	D．The expert’s background information
E．No need to worry about fluoride poisoning
F．Solutions to improper use of fluoride

I have heard that fluoride can help stop dental decay, but I recently read that it is poisonous．Which of these is true? How can children use fluoride safely?

小题1:

This question is answered by Dr Marcia M．Rich who practises general dentistry in Newholt．She is also a lecturer at the University and a writer for the monthly magazine Your Dentist Cares．

小题2:

My answer to the first question is to stress that fluoride works well and is safe when users follow instructions．Young children have a tendency t

o swallow toothpaste, which is why they should only have a tiny amount of fluoride toothpaste on their toothbrush．If this simple measure is taken, parents can be confident that children will be protected against tooth decay, and come to no harm.

小题3:

Almost all medicines have an adverse effect－or even be deadly－if they are not taken as directed．So you are right－fluoride can be poisonous if it is swallowed in very large quantities．It is for the reason that fluoride supplements can only be obtained on prescription from the doctor or dentist．Please be assured that fluoride overdoses are rare－in fact, I have never heard of any fatal incidents related to fluoride poisoning.

小题4:

Scientific studies have shown that fluoride can help to prevent cavities as long as it is used correctly．If fluoride is abused, there is a risk of illness or even deaths in extreme cases．If a deadly amount of fluoride is taken, immediate first-aid could save a life．A person who has swallowed a large amount of fluoride will probably start vomiting．If not, the patient should be given milk or antacid and taken to the nearest hospital for emergency treatment.

小题5:

Taking too much fluoride while teeth are growing can lead to a condition called dental fluorosis．The most likely cause is the swallowing of fluoride toothpastes by young children．It can also be caused by inappropriate use of fluoride drop or other fluoride supplements, for example when fluoride is already is already present in drinking water．

举一反三

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多于选项。
小题1: 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. 小题2: Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims as its own. 小题3: . 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 season. So he is screaming all the time, whether he can see an outsider or not. 小题4:
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 all their own. 小题5:

A．Only he and his family are welcome there.

B．Most of it has to do with attracting mates and setting up territories.

C．Have you ever heard birds sing?

D．Their singing is actually a warning to other birds to stay out of their territory.

E. Have you ever wondered why birds sing?
F. Most of the language is widely used.
G. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

Dear Sir or Madam,

I see your advertisement in a student magazine and I’m interesting to know more about your diving courses. First of all, I should explain that although I can swim I’m not very confident in the water. But you mentioned your advertisement that your instructors are full qualified. Thus I believe they’ll be able to teach someone as me to dive. I have one week’s holiday in the three week of June and would like to know that if there’s a course running at that time. How much does a week’s course worth? Finally, if I decide to go ahead, are there any special equipment I need to buy or is everything provided by your company?

I am looking forward to hear from you.

Sincerely yours,

Tom

根据短文内容，从短文后的选项中选出能填入空白处的最佳的选项。选项中有两项为多余选项。
Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student, they always say,“ My spoken English is poor.” 小题1:I would like to suggest that there may be some reasons for their problems with spoken English.
First, they fail to find suitable words to express themselves due to a limited vocabulary.小题2:However, you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow you as long as you use the words that you know.
小题3: Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate following the rules for grammar and using the right words and spelling them correctly. However, in speaking your aim is fluency. You want to get your message across, to talk to someone in English, as quickly and as well as you can, even though sometimes you may use a wrong word or tense, but it doesn"t matter.小题4:
The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All that hearing is necessary for you to start speaking.
Fourth, most Chinese students are reactive rather than proactive language learners. Instead of actively seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them and wonder why their English always remains poor.小题5:

A．The person you are speaking to will understand you and make allowances for any mistakes he hears.

B．They may try to avoid making similar mistakes next time.

C．Obviously the better answer is to expand their vocabulary.

D．If you have this proactive outlook, then you will see English

opportunities wherever you go.

E. However, their spoken English does not have to remain “poor”!
F. Second, they

are afraid of making mistakes.
G. The second reason lies in the reluctance of using what has just been learned.
