分析 老师建议父母他们12岁以下的孩子不应该允许骑自行车上学.

解答 A考查虚拟语气.通过分析句子结构,可知这个句子中包含了一个省略了that的宾语从句.这里recommend 是建议,所以宾语从句用虚拟语气,should+动词原形,should可以被省略.

点评 在表示建议 suggest、advise、propose;要求demand、desire、request;决定 decide;命令 order、command、require;坚决主张 insist;等动词后跟宾语从句,用(should)+v.(虚拟语气)eg.

16.Eating too much fatty food,exercising too little and smoking can raise your future risk of heart disease.But there is another factor that can cause your heart problems more immediately:the air you breathe.
Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem,but two analyses now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours after exposure.
In one review of the research,scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to   suffer a heart attack within days of exposure than those with lower exposure.A separate study of stroke patients showed that even air that the U.S.Environmental Protection Agency (EPA) considers to be of"moderate"(良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure.However,it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices.So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

11.What can we learn from the text?D
A.Eating fatty food has immediate effects on your heart.
B.Moderate air quality is more harmful than smoking,
C.The EPA conducted many studies on air quality.
D.Stricter regulations on pollutants should be made.
