Burmese pythons (缅甸蟒蛇)
are some of the biggest snakes in the world and also one of the biggest problems in Florida's wetlands. So state officials have asked hunters to lend a hand.
The pythons are originally from Asia. Brought to the US as pets or zoo animals, some were released or broke free into the wild and found Florida's warm weather to be perfect for a new settlement. It is estimated that tens of thousands now live in the everglades and the state's marshy wetlands.
These supersize snakes are invasive species. “The_problem_is_with_animals，” says Carli Segelson, spokesperson for the Florida Fish and Wildlife Conservation Commission. “The pythons eat native birds, reptiles, and small mammals, many of which are threatened species.” Since the python moved in,
several native species, such as bobcats and rabbits, have largely disappeared from Florida's wetlands: So the Florida government has invited hunters to assist in solving this severe environmental problem.
People will be allowed to hunt
pythons
around their breeding grounds for one month, starting on January 12.
Officials are even offering cash prizes to whoever kills the most pythons and to whoever
kills the longest Burmese pythons. They are hoping the contest will significantly reduce the
population of this_dangerous_invader.
“Our goal is to help get rid of the pythons from the wild, educate the public about the
snakes' impact on the Florida ecosystem, and inform them of what impacts nonnative pets can
have if allowed into the wild，” Segelson said.
Experts say it's unlikely the snakes will ever be
removed from the wild in Florida. But they hope to bring the python problem under control and
prevent the snakes from doing more harm.
1．We can infer from the text that Florida must be a place where it is ________.
A．wet and warm B．rainy and windy
C．warm and dry
D．wet and cold
2．By saying “The problem is with animals” in Paragraph 3, Carli Segelson means that ________.
A．the pythons are harmful for other animals
B．people have trouble protecting animals
C．the population of animals is smaller
D．most animals are dangerous to the pythons
3．The underlined words “this dangerous invader”in Paragraph 4 most probably refer to ________.
A．all Burmese pythons in the world
B．the longest Burmese python
C．the killer of Burmese pythons
D．the Burmese pythons in Florida
4．The government's goal of hunting Burmese pythons is ________.

B．to keep the balance of nature
C．to prevent snakes from booming in number
D．to provide necessities for others

I could hear everyone whispering. “Who in our school could draw__15__well？”

Dear Mr. Green，
I'm very exciting to learn that you will start a magazine together. That sounds great and I definitely agree you on that.
Some of the columns that you mention in the letter are really my cup of tea.“Cultural Express” give us a better understanding of the world. Since people from different part of the world have different values, it's necessary to learn from each another. Apart from that, “Blurt Out” is pretty good for Chinese students to learn English idioms and improving oral English. “Entertainment” is also cool! The popular singers, actors or celebrities are so attractively that you absolutely can't miss this part. Teenagers are to fond of popular things, too.
Well, I can't list more. I really can't wait to read this magazine.
Yours，
Li Ming
