“學(xué)會唐詩三百首，不會寫來也會抄”，面對英語四級作文，很多人都不知道如何備考，這個時候多看一些好的文章，對于提升寫作也是很有幫助的。今天我們就為大家整四理了必背英語四級作文范文，一起來看一下吧。 英語四級寫作范文： We Should Balance Our Love Nowadays it is common to see that many parents focus their attention on their children,but leave their own parents without proper care.The most typical example is the phenomenon of empty nest seniors.This problem has aroused the public concern and has become the hot topic of many discussions. Paying little attention to older parents can have serious consequences.First,the elderly often feel lonely and depressed if there is no child with whom they can talk,and this can have a bad effect on their mental health.Second,the aged parents with no children by their sides can have a lot of trouble in their daily life due to disease or old age. In my opinion,we should take the following measures.Children should be encouraged to live with or near their old parents,which is very helpful for them to know their parents,concern and attend their daily life.And it is also necessary for them to create chances to communicate with their aged parents.Besides,our govemmeiit should strive to establish the service system for the elderly and expand its social insurance coverage among them. 英語四級寫作范文： We Shouldn't Totally Turn to the Internet Nowadays,Internet has become an indispensable part in our life,and we use it for various purposes,such as searching useful information and chatting online.However,now more and more people turn to the Internet for help whenever they have trouble in finding solutions to their problems, and this phenomenon has aroused the public's attention. Relying on the Internet to solve all our difficulties can have bad impacts on us.On one hand,since we can always settle the troubles by searching solutions online,we can become very lazy and don't bother to think up answers by ourselves,which can hinder the development of creative thinking.On the other hand,the answers online may be inaccurate or wrong.If we use them without thinking the credibility of them,we may make serious mistakes someday. As far as I'm concerned,we shouldn't completely depend on the Internet to settle problems.When we come across some difficulties,we’d better try our best to find possible solutions.If we make great efforts and still can't come up with an answer,then we can surf online to search solutions.But we should question the correctness of these answers before we adopt them. 英語四級寫作范文： Information Security The human beings are stepping into the information society.The information industry develops very rapidly,so do the hackers,trick-playing teens,exploring children,fraudsters,and serious white-collar criminals.Thus,information security becomes an impending important issue. In case of information breach,the victims-----government department, an organization or an institution,or a company will inevitably suffer great or small loss.Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public’s and users’ confidence will be damaged. Then how to deal with this issue? Technology is only a partial solution to information security.What’s more important is that organizations and companies should promote the awareness on information security to its staff.However,since no system can ever be 100 percent secure,a prevention-only approach to information security management is not enough.Companies and organizations should adopt a dual approach to information security management by combing prevention and detection techniques. 以上就是為大家整理的必背英語四級作文范文的相關(guān)內(nèi)容，希望能夠?qū)Υ蠹矣兴鶐椭?。好的文章總有值得借鑒的地方，多看好的作文范文，對于備考四級寫作也是很有幫助的。

可以輕松的解決。如果碰到一個新詞，就要在腦中搜尋它的相關(guān)信息，這樣一來，就能在考試這么短的時間中馬上浮現(xiàn)了。但是一次的記憶是遠(yuǎn)遠(yuǎn)不夠的，所以適時的重復(fù)記憶也非常重要。 2、多看高分范文，同時再針對當(dāng)中的詞匯句型多樣性進行總結(jié) 雅思寫作機經(jīng)最重要的是是體現(xiàn)在這其中。大家在備考過程里看范文時一般都只是從整體上學(xué)習(xí)了它論據(jù)的安排，卻把細(xì)節(jié)的詞匯句型的運用忽略了，因此大家在上課時也要合理安排時間，將一部分用在對其的講解上。學(xué)生最好準(zhǔn)備一本筆記本專門用做記錄好詞好句和其轉(zhuǎn)換形式。 3、加強雅思寫作學(xué)習(xí)一定要去不斷練習(xí)和記憶 經(jīng)常都有學(xué)生提出，作文提高是否只需要多寫幾篇即可，事實上答案是否定的。我在此表示的加強練習(xí)是在一定的基礎(chǔ)之上
