Firstly,it is necessary for you to realize the Avian flu can be prevented if you develop good living habits. For example,you shouldn’t forget to wash your hands before meals.Besides,don’t spit everywhere and try to cover your mouth or nose with paper or hankerchiefs when you have to cough or sneeze.What’s more, remember to wear the mouth-cover if you have to go to the public places, such as the crowded cinemas,supermarkets, buses,where the A flu may spread easily.
Secondly,of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.

If you have a high fever, go to the hospital without delay for further treatment. Make sure you are not expected to come back to school before the cold or flu is cured.

商业英文书信,一般都要求用打字机或电脑整齐地打印,左边各行开头垂直的,称为垂直式或齐头式(Block style),美国常用这种格式;每段的`第一个词缩进去,称为缩进式或锯齿式(indented style),英国常用此格式。垂直式的职务及签名都在左边的边栏界线,这种格式,在极度尊重工作效率的美国公司,已普遍采用,其它英语写作《英语书信格式与称谓的差异》。正式的商业英语书信要在称呼的上方写上收信公司名称和地址或收信人的名字全称、的职务及地址,称为信内地址(Inside address)。信内地址的写法也有垂直式和缩进式之分,垂直式和称美国式将各行并列,缩进式或称英国式将各行依次退缩。
下面谈谈学习毅力的.问题。如果你有坚强的毅力,那么世界上就没有什么难事。学英语关键是能够持之以恒。
在学习过程中,你应该制订一个计划,一天记住几个单词,一天记住一两个句型。你不要小看“持之以恒”的力量。举个例子:
如果你一天背5个单词一年就是1825个单词,相当于初中三年再加高中一年零两个月的词汇量。如果你坚持两年你就能住3650个单词,相当于中学六年包括本科两年的词汇量。
在制订计划时要遵循以下几项原则:
1、计划要切实可行,不要好高务远。上面的例子已经说明,只要你能坚持天天学习,英语一定能学好。
2、要有坚强的毅力,每天都学习,不因为某些事而耽误了学习。如果哪天的工作没有完成,第二天一定要补上。连续不学习的时间不要超过两天。
3、要有一个帐本,哪天学会了哪几个单词,哪几个句型一定记录在案。
4、为了把单词、句型真正学到手,第二天一定要复习第一天的,第三天一定要复习第二天和第一天的内容。
5、所选择的课本可以是一套或两套,千万别太多。实际学英语的书没有什么好坏之分,只要你能按照一套或两

一般书信可分为称呼、正文、结尾、署名、日期五个部分,每个部分都有一定的格式。
(1)称呼。根据自己和收信人的关系,平时怎么称呼,在信中就怎么写。如给爸爸写信,称呼就写爸爸;写信给老师、同学的信,称呼就写*老师、**同学。称呼要从第一行顶格写起。称呼后面要加冒号(:),表示下面有话要说。
(2)正文。这是信的主要部分。写信人要说的话都写在这里。正文的开头空两格,通常先写问候的话。如果是回信,先要写明来信收到,并对来信中提及的问题或要求办理的事情作出回答。如果写的事情较多,可以分段写,一件事情写一段。每段起行空两格,转折顶格。
(3)结尾。结尾可根据写信人跟随收信人的关系和具体情况,写上表示祝愿,勉励或敬意的祝颂语。如此致敬礼、祝你健康等等。祝愿语一般分两行写。以此致敬礼为例,此致可以紧接正文之后写,也可以另起一行空两格写,敬礼则一定要另起一行顶格写。
(4)署名。在结尾的再下一行的后半行写自己的名字,署名的前面也可以写上跟随对方相应的称呼,如儿、弟、学生等等。
(5)日期。可以写在署名的后面,也可以写在署名下一行的后半行。最报写清年月日,以便查考。
此外,如果信已经写完,又发现内容有遗漏,或某件事叙述不够全面时,在信的后面还可以补写。但是在补写的话前面要加上还有、另外、再;或在后面加上又及等字样。
信写好了,要寄出去,还必须要有信封。现在的标准信封是横写的。信封上面写惧人的邮政编码、收信人地址;中间写收信人的姓名;下面写寄信人的地址、姓氏及邮政编码。
