Read the following passage and mark the letter A, B, C, D on our answer sheet to indicate the correct answer to each of the questions

In the explosion of the linguistic life cycle, it is apparent that it is much more difficult to learn a second language in adulthood than a first language in childhood. Most adults never completely master a foreign language, especially in Phonology – hence the ubiquitous foreign accent. Their development often “fossilizes” into permanent error patterns that no teaching or correction can undo. Of course, there are great individual differences, which depend on effort, attitudes, amount of exposure, quality of teaching and plain talent, but there seems to be a cap for the best adults in the best circumstances

Many explanations have been advanced for children’s superiority; they exploit Motherese (the simplified, repetitive conversation between parents and children), make errors unself-consciously, are more motivated to communicate, like to conform, are not set in their ways, and have not first language to interfere. But some of these accounts are unlikely, based on what is known about how language acquisition works. Recent evidence is calling these social and motivation explanations into doubt. Holding every other factor constant, a key factor stands out: sheer age

Systematic evidence comes from the psychologist Elissa Newport and her colleagues. They tested Korean and Chinese – born students at the University of Illinois who had spent a least ten years in the United States. The immigrants were give a list of 276 simple English sentences, half of them containing some grammatical error. The immigrants who came to the United States between the age of 3 and 7 performed identically to American – born students. Those who arrived between ages 8 and 15 did worse the latter they arrived, and those who arrived between 17 and 39 did the worst of all, and showed huge variability unrelated to their age of arrival

The word “unrelated” in paragraph 3 is closet in meaning to ___

A. unconnected 

B. unfamiliar 

C. unclassified 

D. unidentified 

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42

For more than six million American children, coming home after school means coming back to an empty house. Some deal with the situation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They are called “latchkey children”. They are children who look after themselves while their parents work. And their bad condition has become a subject of concern.

 Lynette Long was once the principal of an elementary school. She said, “we had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was constantly telling them to put the keys inside shirts. There were so many keys; it never came to my mind what they meant.” Slowly, she learned that they were house keys.

 She and her husband began talking to the children who had keys. They learned of the effect working couples and single parents were having on their children. Fear was the biggest problem faced by children at home alone. One in three latchkey children the Longs talked to reported being frightened. Many had nightmares and were worried about their own safety

 The most common way latchkey children deal with their fears is by hiding. They may hide in a shower stall, under a bed or in a closet. The second is TV. They often turn the volume up. It’s hard to get statistics on latchkey children, the Longs have learned. Most parents are slow to admit that they leave their children alone.

What is the main idea of the first paragraph?

A. Why kids hate going home

B. Children’s activities at home

C. Bad condition of latchkey children

D. How kids spend free time
