Guam is a beautiful，small island in the Pacific Ocean.You’ll find happy songbirds，clear blue water，and leafy forest there.But the small island has a big problem: snakes.There are about 2 million brown tree snakes living in Guam.

Has it worked？So far，research shows that there are fewer snakes because of the mice.The worry is that it may be too late to clear the snakes，but Mr Vice from Guam’s Department of Agriculture says this should not stop the islanders from trying.“Our longterm goal is to kill the snake off completely，” he says.

七、书面表达

阅读下面短文,根据其内容写一篇60词左右的内容概要。

Children are starting to carry cell phones at younger ages. In a recent study, 22% of kids in primary school reported having their own cell phone compared with 60% of tweens and 84% of teens. Like many parents, you may wonder whether your child is ready for a cell phone. As you might imagine, there are different attitudes towards it.

Many parents consider safety as the main reason for giving their child a cell phone. They want to be able to reach their child whenever they need to. They also want to give their child the security of being able to reach them whenever he needs to. "This is especially true if your child is home alone after school or walks home alone, says Barbara Greenberg, PhD, a clinical psychologist in Fairfield Country, CT.

However, if your child has a cell phone, he has access to websites that may be inappropriate. He may see content that is violent and could be related to death or sex. "Lots of kids have fantasies in their mind about things they don't understand," Greenberg says. "There's also the issue of inadequate sleep," Greenberg says. "Kids with cell phones are likely to stay awake late into the night playing games and texting with friends. Cell phones also bring the risk of cyber-bullying (网络欺凌). "Before, once you got indoors you were safe," Greenberg says. "But with cell phones and social media, nobody is ever safe from bullying."

"Your child is ready for a cell phone when he can sit down with you to create guidelines for its use," Greenberg says. "If they're unwilling to make this list, they aren't ready." "For most kids, this happens around age 12 or 13, " she says. Parents should make the decision, not well-meaning grandparents or friends who gift your child with a phone. "Ask yourself whether your child has good judgment and a history of good decision making," Greenberg says. If he is immature or tends to make bad decisions he isn't ready.

七、书面表达

Opinions on whether kids are ready for cell phones are divided among parents. Many parents' supporting attitude attributes to the safety provided by cell phones with which children can be reached especially during the separate time. However, others object to it, believing cell phones may bring inappropriate use of websites, insufficient sleep and risky cyber-bullying. It is suggested that cell phones should be given to well-prepared children who can make a responsible guideline list.
