看看这两封邮件是什么意思?
第一封：We have tested your sample & it looks satisfactory to our requirements.Perhaps we can work together for our Mexico plant,but for our US plant,I think the 150% tariff will be too expensive for us.第二封：We did received the sample from you,so we are in the testing processes,as soon I will get results and confirmation form management I will definitely place the orders and will proceed.In any case for taking advanced in time,what is the lead time for this product?Since the time I place the PO and it will arrive to my location?上周我们给客户寄了样品,我问客户样品检测结果如何,然后客户给回复的这两封邮件.第一封邮件是他们公司经理发的,第二封是负责样品检测的人发的.从这两封邮件看,客户有意下订单吗?

主题思想判断
A《傅雷家书》是傅雷写给儿子的两封信,信中饱含着动人的舐犊之情,贯穿于两封信的主旋律都是要儿子做一个坚强的人.
B 小说《故乡》以鲁迅回到故乡的所见所闻为线索,着重描写了闰土和杨二嫂的巨大变化,表现了当时农村经济萧条,破败的事实.
C《纪念伏尔泰逝世一百周年的演说》一文中雨果用巨星陨落来评价伏尔泰在人类历史上的非凡地位.
D曹文轩在《孤独之旅》一文中,叙述了少年杜小康因家道而失学,不得不随父亲去人迹罕至的芦苇荡放鸭子的故事.
哪个是错的?

两封英语E-mail求高手修改！
1.I write this E-mail to express my apologization of missing the on-line quiz firstly.I'm very sorry but I didn't do that on purpose.I knew the quiz is so important that I shoundnt miss,and I used to list it in my schedule,but in fact I was called to join a very urgent meeting at that period,when I finished the meeting and went back to turn on the computer,I found it too late to catch up the deadline of the quiz.I feel sorry and nervous because I do realize it was attached with my final grades,and now I got a grade of zero as a matter of fact.I could provide you with the proof of that urgent meeting and you'll know what I said is all true. And what I would like to know sincerely is that whether you could kindly give me another chance to take the quiz now that I could make up the terrible mistake.Maybe this request is not reasonable because anyone who didn't attend the test was supposed to suffer the consequence himself,but I really don't want to get a grade of zero because I have already prepared this test for much time.I studied hard all the time in your course because my goal is to get a excellent result in my final evaluation.But if in this test I get 0 to put on record for such a reason I think I'll be really depressed because I have not done anything wrong actually.Please give me a chance.
2.My name is Dabing and I'm 30 years old.I write this E-mail to make a job application of product designer.I have just graduated from the department of design in Harbin University.And I used to get some famous design awards.In 2005,I got Redbot design award for a disc-shaped MP3 player.In 2006,I got EastUnion design award for a creatively streamlined design of mobile phone.And in 2009,I got first prize in the design competition of East China.I think maybe it's not enough but I do make progress everyday.I love designing and I find inspiration from life to enrich my design basic.If you could give me a chance to work and get trained in your company,I think I will not let you down.
On the other hand,I am full of energy and enthusiasm,when I face trouble and challenge,I will try to solve them.I regard chanllenges as great treasure in my life.I'm serious with my works and I will never finish my work after deadline.I always try my best to make my product design perfect.I do know Banana company is a excellent IT company,and I entirely agree with the product concept of Banana "Creative and humanity".It's also a important goal for me.And Banana is famous for giving designer a free zone to design,I think it's just what I want.I'm eager to devote my effort to make Banana better.A chance for me will finally prove that you and me are all right.
