But just being able to communicate clearly with written words is a learned skill. Because the words we use to write with are the same words we use to think with, learning to write well has implications going beyond the merely technical. As we improve our writing ability, we improve our ability to think--to build an argument, to frame issues in forceful ways, to 【2】 seemingly unrelated facts into a coherent whole.

And despite the recurring pessimistic opinions about the "end of literacy" and the "death of the 【3】 word", the reality is that we write more than ever these days. While it's a rare person who sits down with pen and paper in hand and writes a letter to a friend or loved one, we【4】 emails at an astounding rate. We also frequently write letters, proposals, memos, speeches and dozens of more【5】 types of documents In a word, we are 【6】 writing creatures.

It's no wonder that businesses repeatedly cite "communication skills" as the single most 【7】 trait in new employees. The problem, though, is that we are as a society 【8】 bad at writing. That is a great danger. Out classroom is filled with unmotivated students who could care less about writing. But being able to write well vastly improves students' potential for success as it helps them to think through problems and express their ideas more effectively

The deadliness begins with the sweet-smelling fruit. As British radiologist Nicola Strickland and her friend discovered, even a single bite of the green apple-like produce can lead to hours of suffering. The scientist says within minutes of eating the fruit, she and her friend experienced “a strange peppery feeling” in their mouths. A few hours later, the two could barely swallow any solid food. Fortunately, the symptoms started to reduce after about eight hours and the fruit did not cause any long-term damage.

Many plants have poisonous bark and leaves to prevent grass-eating animals. However, the fruits are usually edible allowing animals to feed on them or carry seeds to help with reproduction. But since the manchineel fruits are largely transported by ocean tides, the tree does not need help to reproduce.

The tree’s thick and milky white sap (树液) is equally dangerous. Contact with the skin can lead to symptoms that range from headaches to respiratory(呼吸) problems. Exposure to the eye can even cause “temporary painful blindness”. Given that the sap’s most dangerous toxin is highly water soluble, experts advise not using the tree for shade during a rain shower, as raindrops carrying the sap could easily burn your skin.

The fear has resulted in almost destroying the tree in Florida where it is on the list of endangered species. While removing it altogether may seem like the logical solution, experts argue that the manchineel trees are important for local ecosystems. In addition to protecting against ocean winds, the dense manchineel trees also prevent ocean erosion in Central America. The tree’s wood is very popular with Caribbean carpenters who have learned to neutralize its poisonous sap by drying the bark in the sun. In Central and South America, the locals use the bark to treat body swelling caused by injury and infection.

On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more than they did in 1981. They also did more household work and participated in more of such 【1】 activities as soccer and ballet. Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log half that time. All in all, however, children’s leisure time 【2】 from 40% of the day in 1981 to 25%.

“Children are affected by the same time crisis that affects their parents,” says Sandra Hofferth, who 【3】 the recent study of children’s timetable. A(n) 【4】 reason, she says, is that more mothers are working outside the home. Nevertheless, children in both double-income and “male bread winner” households spent 【5】 amounts of time interacting with their parents, 19 hours and 22 hours 【6】. In contrast, children spent only 9 hours with their single mothers.

All work and no play could make for some very messed-up kids. “Play is a(n) 【7】 way a child explores the world and learns about himself,” says T. Berry Brazelton, professor at Harvard Medical School. Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week 【8】 in it.

The children 【9】 spent a quarter of their rapidly decreasing “free time” watching television. But that, believe it or not, was one of the findings parents might 【10】 as good news. If they’re spending less time in front of the TV set, however, kids aren’t replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let’s face it, who’s got the time?
