书面化一点,快,

行善是对生意有利

过去式是用在一般过去时的,过去分词表示被动的加ed,现在分词是动词加ing形式表示主动.
我觉得楼主该弄懂的不是过去式的问题.是被动语态和过去分词的问题

He is off today.

我觉得已经很书面了

简单的：整点+分钟 如 8点40分 eight forty 一般就说到分.如是 “8点40分57秒 ” eight forty and fifty-seven seconds.
复杂的：分钟+past整点（30分钟以内）.如 8点25分 twenty-five past eight.
分钟+to 整点（超过30分钟) 如 8点40分 twenty to nine.(九点差20分钟）

用生铁精炼而成的比较纯的铁.含碳量在0.02%以下,又叫锻铁.熟铁很软,延展性好,可以拉成丝,容易锻造和焊接.
一般含碳量小于0.02%的叫熟铁或纯铁,含量在0.02-2.11%的叫钢,含量在2.11-6.69%的叫生铁.熟铁软,塑性好,容易变形,强度和硬度均较低,用途不广；生铁含碳很多,硬而脆.
（Q235）属于普通碳素结构钢,一般用做建筑材料和不重要的机械结构材料,使用时一般部进行热处理.再说这种钢也不能热处理,低碳钢热处理性能不好.要是必须提高表面力学性能,要先进行表面渗碳,在进行表面淬火.
普通结构碳素钢,这类钢对化学成分要求不甚严格,碳、锰含量可在较大范围内变动,力学性能不太好.

比如：It is 这是（单数）书面化的

1个人归2个人或多个人管,到底听谁的呢?唯一上级就是说只听一个上级的命令,其他的一概不理.这样金字塔结构才会有很好的执行力,这是管理的一个重要成分.

首先你那句话是有问题的,应该改为
you need to know what you are short of.因为what you are short of是know的一个宾语从句,从句要用正常语序.我个人觉得最简洁的说法是：you should know your weakness.无论是口语还是书面都可以.英语很灵活的,为什么一定要用一个形容词去表达呢?用一个现成的名词更简洁,而且很通俗易懂.另外你要用scarce是不对的,因为scarce常指物品稀缺,不能用于指人有弱点.

首先告诉你,这是非常典型的美式口语.美式口语与英式口语最大的不同就是：随意、夸张.
所以gotta = going to,go to
wanna = want to
甚至还有I have got a ticket.
这里的have got就是口语化的,并非是现在完成时
但要注意的是,这些词都只能在日常生活中使用,比如聊天啊 歌词里啊,但是正规的书面语是绝对不允许这么用的.尤其是作文哦!

I'm here!

所谓志者即有远大理想的人,心中怀有美好梦想的人,在通往美好梦想的路上的路上一定会有挫折,有志人则会竭尽全力解决问题,克服困难,所以有志者自有千计万计.对于没有理想的人,就无所谓了,所以无志者只感千难万难.推荐此句,只为让大家明白：阳光总在风雨后!希望大家为了心中的理想永不放弃.

Striving for perfection from the beginning to the end

因为有所倚仗而毫不害怕,或毫无顾忌.比如自己有点才能,不把别人放在眼里.又比如抓到别人的把柄,恐吓别人,心里一点都不害怕.

Brief Analysis of the Pedantic Trend in the Oral Presentation of English Speech by Chinese Students
注：
1. Analyze是动词,analysis是名词.这里应该用名词.
2. written format是硬译,英语无此表达.比较贴切的词是pedantic.
3. verbal本意是与词有关的,可以既是口语,也是书面语.现在常与oral通用,专指口语.但是为了准确,还是用oral更好.
4. 介词、冠词的用法要小心.楼上的乱用一气是不行的.
5. 其实最开始的Brief可以去掉.”浅析”是谦虚的说法,并不是说真的很浅.翻译成Analysis就可以了.

陈豪在北京的ABC美国公司工作.他和美国同事Amy晚上要一起参加同事James的告别晚宴,由公司北京办事处主任戴维斯主持.(Office ambience)A：Chen Hao,you need to be prepared for a lot of toasting tonight.
C：Toasting?烤面包?A：No,I am talking about honoring someone at a meal or reception by raising a glass of wine,champagne or water and offering a few kind words about that person.
C：噢,你是说祝酒啊.西方人祝酒有什么规矩吗?A：There are two kinds of toasts.There is the informal toast that the host offers at the beginning of the meal to welcome his guests.
C：那是戴维斯的事吧.我们有什么要做的吗?A：Mr.Davis will stand,raise his glass and thank everyone for coming.He will take a sip of his wine.Then the guests,who remain seated,raise their glasses in response and take a sip.
C：就是说我们都不用站起来,只要举起杯,然后抿一口酒就行了.那另外一种呢?A：The other is more formal and comes near the end of the meal,usually during dessert.Champagne will be served.After each toast,everyone raises a glass and takes a sip of champagne.
C：是不是每个人都要说祝酒辞呢?A：Not necessarily,but you will be expected to toast James since you worked closely with him.
C：幸亏你事先告诉我.不过那我该说些什么呢?A：You could say how good James was to work with,tell a funny story about him,wish him success in his new position or use a favorite quote.
C：讲笑话是我的长项.不过我还是得赶紧去准备准备,一会餐厅见.******宴会结束后,陈豪和Amy一起搭出租车回家.A：Chen Hao,Your toast was excellent and you seemed completely at ease.You obviously practiced your remarks.
C：这可得谢谢你.还有啊,幸亏你特别提醒我每次只要抿一小口,我真没想到有这么多人祝酒,不然非喝醉了不可.A：It is acceptable etiquette to raise your water glass instead of the champagne flute.I usually just raise my glass to my lips so it appears that I am drinking when I am not.
C：怪不得,我还以为你酒量过人呢!不过Amy,我还有个问题.别人为他祝酒,James好像从来不举杯,也不喝.这样做会不会不礼貌?A：Not at all.That was correct etiquette.You never drink to yourself.Only to other people.
C：噢,所以被别人祝酒的人自己是不喝的.幸亏被祝酒的人不是我,否则我肯定会闹笑话.A：No you wouldn't.I would have warned you about that.
