Q:  Person1:       Since China was open to the outside world , its trade forms have become much more flexible . One of these commonly used forms is co-production . Would you please do a bit explanation of it , Mr . Walker ?  
 Person2:Well , under this arrangement two parties cooperate to manufacture a product or a category of products , for example , machine tools for export . Each party produces and supplies a part of the components and parts ; one party is a Chinese enterprise , the other , an overseas firm . Most probably , the foreign counterpart contributes technology and equipment , and sometimes , parts and components , while the Chinese enterprises factory building , labor and other resources to the cooperative production . They join hands and fulfill orders together by an agreement or a contract .  
 Person1:        I suppose that the assembling of these components and parts , particularly the marketing of the finished products should take place in China .  
 Person2:Not necessarily . It depends on the contract stipulations . They may be marketed in the foreign country where the other party is located , or even in a third country .  
 Person1:        I think the principle of co-production is to expand export trade . It's a reciprocal business , isn't it ?  
 Person2:Yes , you are right . Either party is not well-equipped to produce the final products single-handedly , but they can enter into an agreement . In such case , each side contributes different resources to make the manufacture of a certain product or a category of products possible .

Q:  Person1:       Ok , so who are we going to invite to our dinner party ? 
 Person2:Well , we have the Thompsons , the Greens , and the Anderson , about twelve people total . 
 Person1:        Don't forget my friend Andy from the office . He has nothing to do on Friday , so I invited him over . 
 Person2:But that makes thirteen people ! We can't have thirteen people for dinner on Friday ! 
 Person1:        Why can't we ? 
 Person2:It's an old superstition . If we have thirteen people at the table , then it means bad luck . Can Andy bring a date ? 
 Person1:        I'm not sure . He just broke up with his girlfriend recently , and I don't think he's in the mood to start again so soon . 
 Person2:But we can't have thirteen for dinner ! 
 Person1:        I think you're making a mountain out of a molehill . It's only a superstition . It really doesn't mean anything . 
 Person2:Absolutely not ! I refuse to have thirteen people for dinner on Friday ! 
 Person1:        Ok , ok . I'll ask my sister to come . That way we'll have fourteen for dinner . 
 Person2:That's better .
