Snake dishes have become popular in recent years．Snake meat is often seen in restaurants. It seems that eating snake is now in fashion and if you haven't eaten snake yet, you're considered “out of date。”

    But I wonder whether all of the trends(趋势)are worth following．

    Some people may defend(辩解)themselves by saying that eating snake is good for their health.But these people don’t find out that mice and worms are often in snakes' bodies，therefore,there are many parasites(寄生虫)found inside smkes．they may be bad for our health.

  Apart from this，we're sorry to see that more snakes are being killed by a butcher's(厨师的) knife.

    According to the English newspaper：Shanghai Star，about l000 tons of snakes are eaten every year in China．In Shenzhen of Guangdong Province，sometimes as many as 10 tons of snakes are served on dinner tables in a single day．

    If we still turn a blind eye to this，a vicious circle(恶性循环)will be created．if more snakes are eaten by people，the number of snakes will drop，but the number of mice will increase，which will result in a decrease(减少)crop output(产量)．

    This will make more people hungry．Who wants to see a tragedy(悲剧)happen?

    Therefore, let’s not eat snake any more．To protect the snakes is to protect  ourselves．

1．The writers thinks          ．

    A．eating snake meat is good for our health

    B．eating snake meat isn't bad for our health

    C．eating snake meat is expensive

    D．eating snake meat may do harm to our health

2．“Out of date” means         ．

    A．流行            B．赶时髦                C．迟到                   D．不合适宜

3．In Shenzhen，as many as 10 tons of snakes are        ．

    A．often eaten in a month                       B．eaten in a day sometimes

    C．eaten in a single Day                         D．never eaten in a single day

4．Nearly         tons of snakes are served on dinner tables in a year in China．

    A．ten               B．ten hundred          C．ten thousand          D．one million

5．Why does the writer say that to protect snakes is to protect ourselves?

    A．Because snake meat is good for our health．

    B．Because snake skin can used to make many beautiful shoes，bags and clothes．

    C．Because eating snake is now in fashion．

    D．Because a drop in the number of snakes will result in a decrease of crop output．

阅读理解(Reading comprehension)：

　　The Peppered Moth(蛾), a kind of insect, is found in England. It is light brown in colour and likes to settle on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.

　　But with the development of industry, smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place：in industrial areas, the Peppered Moth began to change colour. It became darker as well. Though the change took several years, some scientists soon notice that newly born moths were a little darker than usual.

　　A scientist called Kettlewell decided to make a careful study of this phenomenon(现象). He marked some of the light moths and some of the darker ones, and set them free in the woods near Birmingham, an industrial city. Later, recaptured(重新捕获) as many the marked moths as possible. (The results were given in the chart.)

　　Kettlewell's research was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke factory pollution.
