Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (肌腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.

Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.

Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.

American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.

Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.

However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版税). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.

C.the sewing machines couldn’t work finally

D.workers who feared the loss of their jobs to a machine set fire小题2:Why did the court force Isaac Singer to pay Elias Howe a lifetime of royalties?

A.Because the judge was against Singer for his unfriendly attitude.

B.Because Howe had already patented the lockstitch used by Singer.

C.Because Singer had borrowed money from Howe and never repaid it.

D.Because Singer and Howe had both invented the same machine.小题3:Which of the following would be the best title for this passage?

A.A Stitch in Time Saves Nine

B.The Case between Howe and Singer

C.Patent Laws on the Sewing Machine

D.The Early History of the Sewing Machine

问答题

国内电子产品出口商A公司自2008年起与新西兰B公司开展进出口贸易;合作初期B公司付款较为及时,双方合作关系良好。当时B公司电话要求A公司出运时使用海运单。

2009年初,A公司继续出运价值50万美元的货物,合同约定的付款方式为D/P AT SIGHT。按照B公司指示,A公司将货物直接发往最终买家澳大利亚C公司,A公司出运时使用海运单。应付款日过后,B公司却表示,由于最终买家C公司破产,未向其支付货款,因此拒绝对A公司履行付款义务。

在多番催讨无果的情况下,A公司遂委托中国信保代为进行海外追讨。 中国信保在收到A公司的委托之后立即将案件交由新西兰当地律师处理,律师随即发函B公司,要求其对本案项下未付欠款做出合理解释并尽快履行付款责任。B公司依旧借口最终买家C公司破产,其未收到C公司付款而拒付本案项下货款。鉴于上述情况,中国信保一方面要求新西兰律师继续同B公司交涉,明确指出其未收到最终买家付款的事实不能成为拖欠A公司的理由,要求立即履行合同约定的付款义务;另一方面则指示A公司积极联系当地其他买家,必要情况下转卖或者退运本案项下货物以避免更大的损失。

而就在B公司迟迟不付款,A公司准备安排退运的时候,经调查得知C公司早已提货,货物已经被列为其破产财产。 由于贸易合同为A公司与B公司订立,A公司是按照B公司指示才将货物出运至澳大利亚,已完成了合同项下的交货义务。

那么,无论货物是否被提走,B公司均应承担完全的付款责任。因此当地律师立即要求B公司付款,否则将考虑采取法律措施。此时B公司却回复称,按照原本设计的贸易流程,C公司在向其付款之前不会得到正本货运单据,更不可能提货,而由于A公司在发货时使用了“海运单(Sea Waybill)”,导致C公司不需出示正本单据就把货提走。故B公司主张,是A公司的过失导致其失去对货权的控制,难以收到货款,并因此拒绝承担任何付款责任。

至此,本案的焦点从简单的拖欠货款变为复杂的贸易纠纷,追回货款的前景变得十分渺茫。 本案贸易双方约定的付款方式为D/P AT SIGHT,即买方接到银行通知后需立即付款才能拿到正本单据,继而清关提货,出口商在合同中设定此付款方式的目的也在于把控货权,控制交易风险。但仅仅由于出口企业在出货时签发的不是通常使用的提单而是“海运单”,便导致了进口商不需付款即可提货,大大增加了收汇风险。

根据以上信息回答以下问题:
