(A)
Handball is a hugely popular sport in Europe and Asia, and it is one of the fastest and most exciting sports in the world. It combines basketball and soccer with the splendid saves of water polo.
Handball is played on an indoor court (the size of two basketball courts) and there are goals at each end. There are twelve players on each team, two goal keepers and ten field players, but there is a maximum of one goalkeeper and six field players from each team allowed on the court at any one time. The idea is simple: score more goals than the other team.
The ball is made of leather or a synthetic material and it must be of perfectly round shape. The surface must not be shiny or slippery. The size and weight of the ball varies for male and female teams, and adult and junior teams.
Handball has the same free-ranging play as basketball, with all players except the goalkeeper constantly moving from attack to defense. The goalkeeper uses hands, feet, head and body to keep out the other team’s shots.
The origins of handball are unclear. Many people think that it developed as a training game for soccer, to be played in the off reason, or when it was snowing. Now, in countries where handball is popular, players can earn large sums of money, and indoor stadiums seating over ten thousand people sell out regularly. Handball has been played at the Olympics since 1972.
75. The passage tells us that handball was most probably developed ________.
A. as an alternative to basketball.
B. by supporters of water polo.
C. for the 1972 Olympics.
D. as a training game.
76. In which order does the information appear in the passage?
A. beginning of the sport; type of ball; court size; team members
B. court size; team members; type of ball; beginning of the sport
C. court size; type of ball; team members; beginning of the sport
D. beginning of the sport; team members; type of ball; court size
77. From the statement “The idea is simple”, we know that in handball the ________.
A. players can change positions
B. court is clearly marked
C. game has only one objective
D. players can earn a lot of money
78. The main purpose of this passage is to ________.
A. describe an interesting sport
B. show how the rules of handball have changed
C. list the world champion handball teams
D. increase the number of teams at the Olympics
(B)
We find that bright children are seldom held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in dividing the class of the pupils grouped according to their abilities and intelligence. It doesn’t take into consideration the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright children. After all, it can be quite discouraging to be at the bottom of the top grade!
Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one part of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their study ability. We also value personal qualities and social skills, and we find that mixed-ability teaching helps to bring about all these parts of learning.
Sometimes the pupils work in pairs; sometimes they work alone, and they can do this at their own speed. They also have some formal class teaching when this is suitable. We encourage our pupils to use the library, and we teach them the skills they need in order to do this well. An advanced pupil can do advanced work: it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every encouragement to achieve this goal.
79. In the passage the writer ________ “mixed-ability teaching”
A. criticizes
B. questions on
C. appreciates
D. objects to
80. The writer thinks that a teacher’s main concern should be the development of the student’s ________.
A. social skills
B. total personality
C. learning ability and communicative skills
D. intellectual ability
81. The phrase “held back” in the first line means ________.
A. “made to remain in the same class”
B. “forced to study in the lower classes”
C. “drawn to their studies”
D. “prevented from advancing”
82. The purpose of the writer in writing the passage is to ________.
A. argue for teaching bright and not-so-bright pupils in the same class
B. recommend pair work and group work for classroom activities
C. offer advice on the proper use of the library
D. put emphasis on the importance of proper formal classroom teaching
(C)
It moved without a ripple, a moon-white circle beneath the surface, and in a few seconds it was as far away as it had been when he had first sighted it. Then it broke the top of the water. Jonsai was astonished.
It was a turtle.
Jonsai rubbed his eyes, thinking that the sun had weakened them. It was not unusual to find turtle feeding near the edge of the reef.
But this was not an ordinary turtle. It stayed there on the surface, white and shining.
The creature stayed still for some time. So did the boy. Leaning forward, he stared without moving, disbelief giving way to a small fear. His heart was beating wildly.
There was no such thing as a white turtle!
His mind moved first. Tonight the men would return from the pig hunt. Samu and Aesake would be at the feast with the men. He, Jonsai, would have to sit with the women and children. But what would happen if, at the height of the feasting, Jonsai brought forward a gift for Chief Vueti, something he had never seen before, a present that would make him the envy of every chief on the island?
His heart beat fast, but steady now, as he got closer, moving swiftly like a thief. He would leave his spear hidden under the raft. That wonderful shell must not be pierced. The only way to catch the turtle was by stealth.
83. Jonsai was surprised when he saw the turtle because the turtle ________.
A. was the Chief’s favorite
B. moved very slowly through the water
C. was white
D. was not afraid of him
84. Jonsai’s main reason for wanting to catch the turtle is to ________.
A. provide food for his family
B. make the other people envy him
C. get the shell for jewelry
D. impress the chief of his village
85. In the last paragraph, as Jonsai moves towards the turtle, he feels ______.
A. determined but sad
B. unsure but excited
C. jealous and unsure
D. worried and upset
(D)
Mrs. White was 67 when she moved out of the house where she had lived most of her life. The house was pulled down and a new block of flats was built there instead. At about the same time her only son was offered a job in Canada. Since the shopping and the housework had become too much for her, and her son and his wife were not able to look after her any more, Mrs. White had to be taken to Homefield Old People’s Home. She still had some friends near her old home, but now she was separated from them. During the first few months she was visited by friends and former neighbours, but Homefield was a long way from where they lived, too far away for old people.
At Homefield Mrs. White was given a small room of her own, and she was well looked after. But she knew no one when she arrived, and she was not able to make friends there. She was well liked by the people who worked there, but she kept apart from the other old people and spent most of her time in her room. After a time she was hardly ever seen at meetings and social evenings.
Although she was in poor health and had to be treated for a weak heart, she did not complain. “After all,” she said, “lots of people are worse off than I am.”
What she disliked most was the “quietness” in the home, and what was even worse was that her son was not able to see her, not even at Christmas.
86. Mrs. White was moved out of her old house mainly because ________.
A. her son was going to work in Canada
