【題目】閱讀下列短文，從每題所給的四個選項 A、B、C、D中選出最佳選項。B
Most of my sweet memories are from my childhood. There are always so many interesting things in the far away village where I grew up. One thing that leaves a deep impression on me is shearing the sheep.
In my village, sheep are washed and sheared (剪毛) sometime in the month of June. This should be done quite early in the month, before the hot days begin.
It's best for the sheep to have the wool taken off, or they will be too hot in the summer time. When the time comes for washing the sheep, they are driven to a pond or a little river. Then they are thrown into the water, one at a time. The men who are in the water catch them, and wash them to get the dirt all out of the wool. When the wool is dry, the sheep are taken to the shearer; and he cuts off the wool with a large pair of shears. In a short time, before the cold winter comes, new wool grows out on the sheep. By the coming of spring, there is so much that it must be cut off soon.

（1）When are sheep sheared usually?
A.In February
B.In June.
C.In April.
D.In August.
（2）According to the passage, why do people cut off the wool of sheep?
A.They do that for fun and pleasure.
B.They do that as a sport and exercise.
C.They do that to help sheep spend hot summer.
D.They do that to make sheep look more beautiful.
（3）What does the underlined word "shears" mean?
A.Knives
B.Scissors.
C.Baskets.
D.Rivers.
（4）How often do people shear their sheep?
A.Several times a year.
B.Twice a year.
C.Once a few years.
D.Once a year.

【題目】閱讀理解
The Double Ninth Festival

The Double Ninth Festival, also named the “Chong Yang Festival”, is celebrated on the ninth day of the ninth month of the Chinese lunar calendar.
The festival began as early as the Warring States Period (475-221 BC). In ancient time, numbers were mysterious and were divided into yin and yang. Yin means something of darkness and yang means life and brightness. The number nine is regarded as yang. The ninth day of the ninth month is a double yang day, so it is called “Chong Yang Festival”. (Chong means “repeat” in Chinese)
People always climb mountains and drink chrysanthemum wine on the Double Ninth Festival. It is hard to say when the customs were created. But there are many stories which are closely related. As recorded in a historical book of the sixth century, in ancient times, there lived a man named Huang Jing. He was learning the magic arts from Fei Changfang. One day, they were climbing a mountain. Fei Changfang suddenly stopped and looked very upset. He said to Huang Jing, “On the ninth day of the ninth lunar month, a big trouble will come to your hometown”. You must go home immediately. Remember to make a red bag for each one of your family members and leave home quickly and climb to the top of a mountain. Most importantly, you must all drink some chrysanthemum wine. Only by doing so can your family members avoid the big trouble.
On hearing this, Huang Jing rushed home and asked his family to do exactly as his teacher said. The whole family climbed a nearby mountain and did not return until the evening. When they got back home, they found all their animals dead, including chickens, sheep, dogs and so on.
Since then, climbing a mountain and drinking chrysanthemum wine became the traditional activities of the Double Ninth Festival, to avoid evil spirits and bad luck. Nowadays, the Double Ninth Festival is also a time for family get-togethers to do some exercise as well as enjoy the autumn scenery.
（1）The Double Ninth Festival began around ______.
A.475-221 BC
B.435-231 BC
C.337-221 BC
D.245-213 BC
（2）People usually climb mountains and ______ on the festival.
A.cook meals
B.feed the animals
C.drink chrysanthemum wine
D.learn magic art
（3）Fei Changfang is ______.
A.Huang Jing's cousin
B.Huang Jing's teacher
C.Huang Jing's friend
D.Huang Jing's neighbor
（4）Nowadays the Double Ninth Festival is also a time to ______.
A.make dumplings
B.buy some wine
C.wear new clothes
D.do some exercise
