It"s none of your busines!These are private

选D吧，，，keep sb doing sth

1 business negotiation specification：商业谈判的详细说明
2 specification
n. 规格, 详述
Can you give me a price list with specification?
你能否给我一份有规格说明的价目单吗?
3 condition勉强能当specification的同义词

你得看完整句话,特别是后半句‘自从上周一他就出差了’,如果用2‘WILL BE’是指还没有发生,前后矛盾.故1对.‘我不知道他要离家多长时间.自从上周一他就出差了’

是选D
根据意思是指过去这个地方被设计成休闲场所,现在用于商业了,这使当地人很不满.

1.改为 one 是正确的.
* 通过一下的句子分析即可明了：
主语：One of the most successful African American businesses in history ,历史上最成功的美国黑人商业之一
同位语：the MOTOWN Record Corporation 即汽车城（指底特律）录制公司
谓语部分：was founded in 1960 于...被创立
句子的意思是：历史上最成功的美国黑人商业之一,即汽车城录制公司于1960年被创立.
说明录制公司是创立以后成为一家最成功的美国黑人商业之一,
* 如果改为 as one,句子的结构就成了如下：
状语：As one of the most successful African American businesses in history 作为历史上最成功的美国黑人商业之一
主语：the MOTOWN Record Corporation
谓语部分：was founded in ...
句子的意思是：汽车城录制公司作为历史上最成功的美国黑人商业之一于...被创立
说明公司是作为已经是最成功的美国黑人商业之一被创立的.但是,创立以前怎么会是最成功的商业呢?
* 下面的资料可能对理解本题有所帮助：
Another popular nickname for Detroit is Motown.Berry Gordy,Junior started the Motown Record Corporation in Detroit in nineteen fifty-nine.African-American singers recording for the company were extremely popular in the nineteen sixties and nineteen seventies.Their records were so successful that Detroit was also called Hitsville.
资料意思是：底特律的另一个昵称叫做汽车城.Berry Gordy Junior 在底特律创办了 Motown Record Corporation,六十年代美国黑人歌手为公司录音是非常受欢迎的.他们的录音是那样的成功以至于底特律还被叫做 Hitsville（打击乐豪宅）.
2.Adult ladybugs often prey on agricultural garden pest,causing many fruit growers to consider them among the most beneficial insects.
1.本题中的现在分词短语 causing...是伴随状语,逻辑主语是 Adult ladybugs.这个句子也可以改为并列句：
Adult ladybugs often prey on agricultural garden pest and they cause many fruit growers to consider them among the most beneficial insects.瓢虫成虫捕食田园害虫,他们促使许多水果种植者在最有益的昆虫中间去考虑它们这些瓢虫.
2.伴随状语中的 causing many fruit growers to consider ...就是 cause sb.to do sth.这个句型,many fruit growers 是动词 cause 的宾语,不定式 to consider 是宾语补足语,其逻辑主语就是宾语,因此这里的 consider 是由 growers 支配的.

1 Our main business is exporting wooden products.
2 We're really sorry that quotations can't be offered now.
3 We've already got he quotations of our T-shirts from our subsidiary.
就是在翻译要灵活使用主被动语态.

主语从句中：others 主语 think 谓语 what 宾语 of you介词短语作状语

当然要用rules.
which从句是个定语从句,用来修饰business empire的,而这个business empire是单数形式,在从句里做主语,因此动词rule要用第三人称单数形式.

非限制性定语从句,which做find的宾语,指代前面的一句话.
如果find后有宾语it或that,可选连词but连接两个完整的句子,
although语气不符.
仅供参考.

就是说假定2012年4月20,这天为非营业日（或是实物交易的预定交易日）,接下来一天是营业日（或是实物交易的预定交易日）,再假定如果由于任何原因（包括由于发生市场干扰事件）,最后交易日期被推迟到原定到期日期之前的2个营业日或更晚,到期日期将顺延至推迟后的交易日期的两天之后的一个营业日（或是实物交易的预定交易日）.

mostly 副词

在澳大利亚,各行各业,不论大小,亚洲人带来的影响力让人有所感觉.
make their influence felt in 的意思是：在……方面使的他们的影响力被感觉出来了

在议会广场的其它地方,羊毛商贩们倾谈着买卖.银行老板正查看着账本.客栈里来自东方的旅客起来得很晚,打着哈欠地呼喊店员给他们送早餐.

in
be arrived at和be arrived in
如果是一个地区就用in
如果是一个小地方（比如说图书馆或者酒吧啥的）就用at

他有信心,是一个成功的商人.

你确定句子是对的?看不全懂

语义来讲,楼主是不是想问为何不用more clearly.
不过你设身处地想想,你在听讲座的时候,你听不清楚,你是喊,“请讲清楚点!”还是“请讲慢点!”
所以,用slowly
所以加more

extensively 主要是指抽象意义上的~widely一般用于广泛使用普遍使用之类的

不可以.
这是个英语的谚语,是固定的用法,不可以随便改动当中的单词.就像形容爱情坚贞不渝的中国成语“海枯石烂”不可改为“水枯石烂”一样.

通常情况下much多用于否定句,用来修饰不可数名词；a number of多用来修饰可数名词,这里的business是不可数名词,所以不可以；a lot of = lots of,答案D少了一个of,如果有of的话是可以的.
如果是病人的话可以说I am going to undergo an operation this weekend.
如果是医生的话可以说I am goign to perform an operation this weekend.
但是如果有上下文的话,直接说I am goign to have an operation还是比较好的.

B
在将来时中表示“多少时间以后”用in + 表示时间的名词,因此A/C不对（after/later用于过去时中表示什么时间以后）
第二,in+时间,有两种表达法：in ten days或者in ten days' time,10天是复数,复数的所有格要变成s'再加time,据此D错在,应该是：in a few days' time

句子应该是
Before you open an account you can talk to several banks to find the one with the best services,hours and interest rates.
hours 是 business hours 营业时间
句子是说
开帐户之前你可以询问几家银行,以找出有最佳服务、最佳营业时间和最佳利率的一家.
