جاء فى كتاب الــ Work Book هذه الجملة Find the mistake
1. My cousin, that is a research chemist, works in the food industry

و حلها :

My cousin, who is a research chemist, works in the food industry.

و فيم يلى شرح لهذه الجملة حيث أنى لم أر بعض الكتب الخارجية تتعرض لها :

كما نعرف أن هناك نوعين من جمل الوصل :
non-defining or non-restrictive :الأول و يطلق عليه و هو الذى لا يضيف معلومة إلى الجملة و يفصل بينه وبين باقى الجملة بــCOmma

مثال :

Albert Einstein, who put forward the theory of relativity, is considered by many as the most intelligent person in human history.
The ELC, which provides language support to PolyU students, is located in the AG wing.

الثانى : يطلق عليه a defining (or restrictive) relative clause و هو النوع الذى يضيف معنى زائد إلى الجملة و لا يفصل بينه و باقة الجملة ب comma مثال :

The student who achieves the highest GPA score in this department will be awarded a prize of $20,000.
Computer games that involve fighting and shooting apparently have a negative effect on young people.

و لا يمكن استخدام that محل who أو which فى non defining clause بأى حال من الأحوال
مثال
Elephants, that are large and grey, can sometimes be found in zoos.
جملة خاطئة

و الصحيحة

Elephants, which are large and grey, can sometimes be found in zoos.
