【題目】（題文）At times my mom has been uncomfortable seeing these qualities in me. For example, when I was 12, I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my plane take off.

Despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space to grow and learn, even when it might have been difficult for her. When I reached my senior year, I decided to move away for college. Once again I found that I differed from my peers: while many of them wanted to stay close to home, I couldn’t wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away, she was supportive and excited for me.

One big thing I realized during my senior year when my mom granted me more freedom was that she actually believed in me and trusted me. That meant a lot. In most time of my life, and especially when I was little, the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best of me. Sometimes it was hard to live up to her standards; getting a single B on my report card would make me feel bad because I knew she wanted me to have all A’s.

I know that her high standards have helped me stay focused on what’s important, like education, and made me who I am. I am thankful for her support and involvement in my life. Most of all I respect her. She is the strongest woman I know and that’s why I have turned out so strong and independent.

【1】（小題1）When the author decided to go to Puerto Rico, his mother ________.

A. wanted to go with him B. worried about his safety

C. didn’t allow him to go D. asked his grandmother for advice

【2】（小題2）The author decided to move away for college to ________.

A. be different from his peers B. keep away from his mother

C. be independent in outside world D. make his mother unhappy

【3】（小題3）We can learn from the third paragraph that the author’s mother ________.

A. had a high expectation of him B. was not strict with him

C. used to expect nothing of him D. cared little about his learning

【4】（小題4）We can learn from the last paragraph that the author ________.

A. is quite grateful for his mother’s trust

B. still doesn’t quite understand his mother’s attitude

C. doesn’t like his mother’s involvement in his life

【題目】閱讀理解
Not all bodies of water are so evidently alive as the Atlantic Ocean, an S-shaped body of water covering 33 million square miles. The Atlantic has, in a sense, replaced the Mediterranean as the inland sea of Western civilization. Unlike real inland seas, which seem strangely still, the Atlantic is rich in oceanic liveliness. It is perhaps not surprising that its vitality has been much written about by ancient poets.
“Storm at Sea”, a short poem written around 700, is generally regarded as one of mankind's earliest artistic representations of the Atlantic.
When the wind is from the west
All the waves that cannot rest
To the east must thunder on
Where the bright tree of the sun
Is rooted in the ocean's breast.
As the poem suggests, the Atlantic is never dead and dull. It is an ocean that moves, impressively and endlessly. It makes all kinds of noise—it is forever thundering, boiling, crashing, and whistling.
It is easy to imagine the Atlantic trying to draw breath—perhaps not so noticeably out in mid-ocean, but where it meets land, its waters bathing up and down a sandy beach. It mimics(模仿) nearly perfectly the steady breathing of a living creature. It is filled with symbiotic existences, too: unimaginable quantities of creatures, little and large alike, mix within its depths in a kind of oceanic harmony, giving to the waters a feeling of heartbeat, a kind of sub-ocean vitality. And it has a psychology. It has personalities: sometimes peaceful and pleasant, on rare occasions rough and wild; always it is strong and striking.
（1）Unlike real inland seas, the Atlantic Ocean is______.
A.always energetic
B.lacking in liveliness
C.shaped like a square
D.favored by ancient poets
（2）What is the purpose of using the poem “Storm at Sea” in the passage?
A.To describe the movement of the waves.
B.To show the strength of the storm.
C.To represent the power of the ocean.
D.To prove the vastness of the sea.
（3）What does the underlined word “symbiotic” mean?
A.Living together.
B.Growing fast.
C.Moving harmoniously.
D.Breathing peacefully.
（4）In the last paragraph, the Atlantic is compared to______.
A.a beautiful and poetic place
B.a flesh and blood person
C.a wonderful world
D.a lovely animal

【題目】A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.

Researchers have discovered that “night milk” contains more melatonin (褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

Night milk quickened the start of sleep and caused the mice to sleep longer.

While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

【1】According to the text, the mice fed with daytime milk _________.

A. started sleep more easily B. were more anxious

C. were less active D. woke up later

【2】Which of the following is true of melatonin according to the text?

A. It’sbeentestedonmicefortentimes.

B. Itcanmakepeoplemoreenergetic.

C. It’susedinsleepingdrugs.

D. Itexistsinmilkingreatamount.

【3】Whatcanbeasuitabletitleforthetext?

A. Night Milk and Sleep B. Fat, Sugar and Health

C. An Experiment on Mice D. Milk Drinking and Health

【4】How does the author support the theme of the text?

A. By giving examples. B. By stating arguments.

C. By explaining statistical data. D. By providing research results.

【題目】根據(jù)短文內(nèi)容，從下框的A---F選項中選出能概括每一段主題的最佳選項。 選項中有一項為多余選項。

A. Adults keep pets with their children.
B. Pet-keeping has a very long history.
C. Pet-keeping may do harm to animals.
D. People keeps pets for their aesthetic need.
E. Caged pets become increasingly popular.
F. Pet-keeping is helpful for children’s growth.


（1）
Pet-keeping is a time-honored tradition. One of the reasons for people to raise dogs or cows was usefulness. While people in the past hunted animals and kept them in their backyards, the civilsed man today is less cruel towards them and is less exploitative(利用的).
（2）
We keep animals as pets because they are attractive. We all have the urge to possess something that has aesthetic（審美的）value, and this is why we treasure paintings or fine furniture. Keeping pets is one form of this urge. A Siamese cat in the house can be a decorative object. Pets are playful animals and they amuse us. A little rabbit amuses us by its playful and lively runs.
（3）
Many parents find it helpful to have pets in the house for their children. Having pets is an excellent way of developing in children the love of animals and responsibility. Children get the opportunity to take on full responsibility for another creature’s life. It will be an educational experience for a child to watch the natural life cycle of an animal. There are psychological benefits for children. Pets are welcome friends for children who are lonely. Pets are excellent companions. Keeping pets means giving love and being loved. We find comfort in giving care and receiving care in return. We get pleasure from their appearance and their behavior.
（4）
As more people move into apartments, there are limitations on keeping of animals like dogs and monkeys. Therefore, caged animals have increased in popularity. Birds fall into this group. We keep them for their beautiful songs and feathers. Fish-keeping is a widespread hobby and the keeper can observe their behavior in the glass tank and study its entire life cycle. The cat is a fine house pet and it fits neatly into human habitation(居住地) without requiring its own cage. They are wonderful hunters, if there are rats around.
（5）
Pets satisfy man’s desire to care for a bit of nature. The pet owner has the responsibility for supplying those needs that nature provides. Pets are amusing and entertaining, but we are in a way doing animals harm by making them live in a human environment. Are we not enslaving(奴役)them?
