C. READING 
I. Read and do the tasks below. 
The generation gap, which refers to a broad difference between one generation and another, especially between young people and their parents, usually leads to numerous conflicts. Such family conflicts can seriously threaten the relationship between parents and children at times. 
It goes without saying that, however old their children are, parents still regard them as small kids and keep in mind that their offspring are too young to protect themselves cautiously or have wise choices. Therefore, they tend to make a great attempt to help their children to discover the outside world. Nevertheless, they forget that as children grow up, they want to be more independent and develop their own identity by creating their own opinions, thoughts, styles and values about life. 
One common issue that drives conflicts is the clothes of teenagers. While teens are keen on wearing fashionable clothes which try to catch up with the youth trends, parents who value traditional clothes believe that those kinds of attire violate the rules and the norms of the society. It becomes worse when the expensive brand name clothes teens choose seem to be beyond the financial capacity of parents. 
Another reason contributing to conflicts is the interest in choosing a career path or education between parents and teenagers. Young people are told that they have the world at their feet and that dazzling future opportunities are just waiting for them to seize. However, their parents try to impose their choices of university or career on them regardless of their children's preference. 
Indeed, conflicts between parents and children are the everlasting family phenomena. It seems that the best way to solve the matter is open communication to create mutual trust and understanding. 
Task 1. Decide whether the following statements are True, False or Not Given. 
1. According to the passage, the relationship between parents and children is 	False
not easily destroyed by the family conflicts. 
2. As children get older, parents let them live on their own way and do what 	False
they are interested in. 
3. Teenagers try to please their parents by wearing traditional clothes. 	Not Given
4. Parents want children to follow their wishes in deciding the education and 	True
future jobs. 
5. Some parents indulge their children with expensive brand name clothes. 	Not Given
6. In order to bridge the gap between the old generation and the younger one, 	True
open communication to promote mutual understanding is the vital key. 
Task 2. Choose the best answers for the following questions. 
1. Why do most parents still treat their teenage children like small kids? 
A. Because children usually make mistakes 
B. Because they think that children are too young to live independently. 
C. Because they think that children can't protect themselves well. 
2. The word "offspring" in the second paragraph refers to ____.
A. parents 	B. children 	C. mind

B. They take care of their children carefully. 
C. They encourage their children to explore the outside world.

5. According to the passage, what are parents' viewpoints about the teenagers' clothes? 
A. Teenagers' clothes get the latest teen fashion trends. 
B. Teenagers' clothes are too short and ripped. 
C. Teenagers' clothes are contrary to the accepted standards and values of the society. 
6. Why do teenagers want to choose their university or career?
