From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first 1 , they were like newborn children, unable to use this 2 tool. Yet once language developed, the possibilities for human kind’s future 3 and cultural growth increased. Many linguists believe that evolution is 4 for our ability to produce and use language. They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood. Therefore there are critical 10 times for language development. Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades. Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed. 16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been 17 from other human beings do not possess language. This demonstrates that 18 with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language 19 than any innate capacities. These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones. 请在2处填上正确答案（）

Passage Four
More than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8.
The department gave a report to the expulsions (开除) as saying handguns accounted for 58 percent of the 6,093 expulsions in 1996 and 1997, against 7 percent for rifles (步枪) or shotguns and 35 percent for other types of firearms.
"The report is a clear sign that out nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. "We need to be tough-minded about keeping guns out of our schools and do everything to keep our children safe."
In March 1997, an 11 years old boy and 13 years old boy using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14 years old boy killed three high school students and wounded five in Dasucah, Kentucky.
Most of the expulsions, 56 percent, were from high school, which have students from about age 13.34 percent were from junior high schools and 9 percent were from elementary schools, the report said.
