A.canB.mustC.need.D.might

分析 最近交通比较拥堵,我也许要晚点到,你能帮我留个位子吗?

解答 答案:D
can能够,可能;must一定,必须;need需要;might也许;句意表达的是不肯定的推测,可以排除BC;might除了表示不肯定的推测外,还表达委婉的语气;如果用can,要换成could才符合语境.故选D.

点评 情态动词的用法是英语中常考的语言点.通常考查的方式有虚拟和推测,本题考查的是情态动词的推测用法.学习时要注意积累.

20.Lead poisoning (铅中毒)occurs when lead is present in high levels in the blood of a person.It is one of the most common medical problems found in children.And it's important to recognize the presence of lead in children's bodies because lead is very harmful.
Children have the tendency to go around and put things in their mouths like paint peelings.This is one of the main causes of lead poisoning.It has also been found that children born in poor families have higher chances of getting exposed to lead.
Some of the common symptoms of lead poisoning in children are headaches,stomach pains,hair loss,muscle weakness,and weight loss,etc.
Lead poisoning can have severe effects and can lead to heart diseases,kidney diseases and neurological(神经系统的)problems.It can also result in mental dullness and a low I.Q.level.There have been cases where lead poisoning proved to be terminal for children.
It's difficult to easily recognize whether a child is affected by lead poisoning,as the symptoms of this disease can occur due to some other medical problems.Therefore,children under the age of 6should regularly be checked to know the level of lead in their blood through blood tests.It's possible to completely cure a child with lead poisoning through treatment.Usually the oral medicine chelator(螯合剂)is given to the children.Sometimes,children are given an injection(注射)for reducing the lead level.Children who have very high level of lead in their blood would need treatment for a long period of time and would also be put on a special diet.
Parents have to take certain precautions to lower the chance of lead poisoning in children.Cleaning the house regularly and removing shoes at the door after coming in form outside will prevent the lead particles from entering the house.Children should be put on a healthy diet,containing high proportions(比例)of calcium and iron,such as eggs,milk,fruits,potatoes,etc.
Which helps to keep the lead levels in control,in the children's bodies.
In short,it's a must to be cautious and careful,and protect your children from the horrible consequences of lead poisoning.
