請(qǐng)大牛們檢查并修改以下托福作文語(yǔ)句
我要用在托福作文里的,主要檢查有沒(méi)有語(yǔ)法錯(cuò)誤,或者怎么表達(dá)能更符合美國(guó)人的思維習(xí)慣,如果能大概評(píng)一下分就更好了（當(dāng)然我指的是單就這些例子或句子而言）,馬上要考了來(lái)不及了,
1.Doing sports will not only increase people's metabolism but also strengthen their immunity.For instance,in the past,many high schools in my city canceled the PE lessons in order to make students focus all their attention to study.As a result,the number of students who were absent from school due to coming down with a cold increased rapidly,which has a bad influence on both the student’s life and the school’s routines.From this case,the consequence of neglect of health is obviously acknowledged.After restoring physical courses,this situation was just alleviated.
2.Food conditions has been improved a lot.A research said that thirty years ago,35 percent of the deaths of children worldwide are caused by hunger.However,with the rapid development of agricultural science and cultivation technology,this situation has been well alleviated today.Hunger is no longer a pressing problem facing our world.Since most people do not need to worry about whether they would starve the next meal,an increasing number of them began to focus on the nutritious value of their foods.How much fat contained in their food?How many calories their food possess?How many vitamins they can obtain from their food?They will take all these things into their consideration.The prevalence of some TV programs which introduce information about food nutrition can be a strong evidence for it.
3.Due to the increasingly keen social competition,finding a job has become one of the pressing problem facing the young today.
4.It is bound to provide good education (tourism) resources to the public.
