问题 判断题

为了避免生活垃圾污染环境,就应该把垃圾集中埋在一块地里 。     (   )

答案

题目分析:生活垃圾通过分类投放、分类收集,把有用物资,如纸张、塑料、橡胶、玻璃、瓶罐、金属以及废旧家用电器等从垃圾中分离出来重新回收、利用,变废为宝,既提高垃圾资源利用水平,又可减少垃圾处置量,它是实现垃圾减量化和资源化的重要途径和手段,垃圾通过分类收集后便于对不同类垃圾进行分类处置,如对有机垃圾 进行堆肥发酵处理,把有机垃圾制成农田用肥和绿化用肥,对没有回收利用价值的无机垃圾进行填埋处置,对热值较高的可燃垃圾进行焚烧处置,有利于资源的回收和利用,既省下了土地,更重要的是避免了填埋或焚烧所产生的污染,还可以变废为宝,符合科学发展观的要求,实现资源的再循环与可持续发展,利于经济,社会与坏境的和谐,进行垃圾分类处理可以防止环境污染,保护生物圈.而把垃圾集中埋在一 块地里,既浪费了资源,又污染了环境,尤其是废电池等能污染土壤、地下水源,危害很大,因此题干的说法不正确。

点评:此题为基础题,较易,解答此类题目的关键是知道垃圾分类处理的意义。

     After Jon Corzine suffered serious injuries in a car accident on April 12, many of the reports focused on his

failure to wear a seat belt. It's reported that seatbelt use has gone up by 10 percent since 2000, hitting a record

81 percent nationwide in 2006. And the agency reports that safety belts saved about 15,434 lives in 2004. But

for some groups, particularly teens and young adults, usage still lags. Sixty-two percent of the 5,135 young

people ages 16 to 20 killed when riding in passenger vehicles (交通工具) in 2004 were not wearing safety belts.

So if you're the parent of a teen, remind them to fasten up every time they get into a car. Yes, even it's just for

a short ride and even if they're in the back seat. And for kids under 13, be sure to follow these safety guidelines

(准则).

     ● Children from birth until age 1 or under 20 pounds should ride in the back seat in a rear-facing (向后)

child safety seat.

     ● Children over 1 year old and weighing more than 20 pounds can ride in a forward-facing child safety seat

in the back seat.

     ● All children who have outgrown child safety seats should be properly put in booster seats (幼儿加高座位)

until they are at least 8 years old or 4 feet, 9 inches tall.

     ● Once children outgrow their booster seats, they can use an adult seat belt in the back seat as long as it fits

properly.

     ● New rules require manufacturers(制造商 )to start using"smart" air bags for all 2007 cars. The new air

bags are constructed so that they don't injure smaller passengers in the front seat.

1. In 2000 about ______ percent people use seat belts nationwide.

2. The underlined word "lags" in Paragraph 1 means ___.

3. According to the safety guidelines, we can learn that ______.

A. children can never use an adult seat belt in the back seat

B. when the children are in the back seat of the car, they needn't wear a seat belt

C. a 2-year-old child can ride in a forward-facing child safety seat in the back seat

D. the smaller passengers in the cars with new air bags won't have danger

4. What can we infer from the passage?

A. Jon Corzine was putting the seat belt on when the accident happened.

B. You don't have to wear a seat belt when you are just going for a short ride.

C. 62% of the young people were killed when riding in passenger vehicles in 2004.
