The red crab (紅蟹) lives on Christmas Island in the Indian Ocean and has been found nowhere else in the world. But on its homeland it is a very significant species — some 120 million individuals cover the rain forest floor and play a major role in determining the structure of the ecosystem.

These large crabs are active during the day but prefer to stay in the shade and can die in the heat of direct sunlight. They feed on fallen leaves, seeds, fruits and flowers, recycling nutrients and helping to determine the spread and composition of native plants.

Most of the year the red crabs live in the holes they dig throughout the forest. During the dry season they hide in these shelters to keep their body wet and remain there for two to three months. But when wet season returns in October or November they begin a legendary mass migration to their seaside breeding (繁殖)  grounds, moving in colorful wave that wash over all obstacles like roads (including special passages and some closed roads built for the red crab) and even seaside cliffs.

The annual migration is also closely tied to the lunar schedule. The crabs arrive at the coast and breed at such a time that the females can produce eggs and develop them in caves for a dozen or so days before carrying them into the sea exactly when high tide turns between the last quarter and new moon. During this period sea level on the beaches varies the least and offers an easier approach, which is so important that if the weather delays the migration crabs will put off laying eggs until the next lunar month.

Red crab eggs grow right away, and the young live in the sea for a month before returning to the coast, changing into air breathers, and slowly returning inland to begin the cycle once again.

60. The red crab is a very significant species on its homeland because _____ .

A. it’s gradually dying out    

B. it’s not found anywhere else

C. it’s well protected by the local people       

D. its huge population affects its native ecosystem

61. According to Paragraph 2, _____ influences the plants on Christmas Island.

A. the eating habits of the red crab   B. the heat of the direct sunlight

C. the homes of the red crab        D. the migration of the red crab

62. It can be inferred from the passage that _____.

A. red crabs migrate by swimming in colorful ocean waves        

B. the islanders are friendly to the migrating crabs

C. red crabs live in the holes all the year round   

D. people have built special shelters for red crabs

63. What’s important for the red crab to reproduce their young?

A. The right caves.               B. The number of the crabs.

C. The movement of the moon.     D. The temperature of the tide.

Franz Kafka wrote that “A book must be the ax(斧子)for the frozen sea inside us.” I once shared this sentence with a class of seventh graders, and it didn’t seem to require any explanation.
We’d just finished John Steinbeck’s novel Of Mice and Men. When we read the end together out loud in class, my toughest boy, a star basketball player, wept a little, and so did I. “Are you crying?” one girl asked, as she got out of her chair to take a closer look. “I am,” I told her, “and the funny thing is I’ve read it many times.”
But they understood. When George shoots Lennie, the tragedy is that we realize it was always going to happen. In my 14 years of teaching in a New York City public middle school, I’ve taught kids with imprisoned parents, abusive parents, irresponsible parents; kids who are parents themselves; kids who are homeless; kids who grew up in violent neighborhoods. They understand, more than I ever will, the novel’s terrible logic—the giving way of dreams to fate (命運).
For the last seven years, I have worked as a reading enrichment teacher, reading classic works of literature(文學(xué)) with small groups of students from grades six to eight. I originally proposed this idea to my headmaster after learning that a former excellent student of mine had transferred out of a selective high school—one that often attracts the literary-minded (有文學(xué)頭腦的) children of Manhattan’s upper classes—into a less competitive school. The daughter of immigrants (移民), with a father in prison, she perhaps felt uncomfortable with her new classmates. I thought additional “cultural capital” could help students like her develop better in high school, where they would unavoidably meet, perhaps for the first time, students who came from homes lined with bookshelves, whose parents had earned Ph.D.’s.
Along with Of Mice and Men, my groups read: Sounder, The Red Pony, Lord of the Flies, Romeo and Juliet and Macbeth. The students didn’t always read from the expected point of view. About The Red Pony, one student said, “it's about being a man, it’s about manliness (男子氣概).” I had never before seen the parallels between Scarface and Macbeth, nor had I heard Lady Macbeth’s soliloquies (獨白) read as raps, but both made sense; the interpretations were playful, but serious. Once introduced to Steinbeck’s writing, one boy went on to read The Grapes of Wrath and told me repeatedly how amazing it was that “all these people hate each other, and they’re all white.” His historical view was broadening, his sense of his own country deepening. Year after year, former students visited and told me how prepared they had felt in their first year in college as a result of the classes.
Year after year, however, we are increasing the number of practice tests. We are trying to teach students to read increasingly complex texts, not for emotional punch (碰撞) but for text complexity. Yet, we cannot enrich the minds of our students by testing them on texts that ignore their hearts. We are teaching them that words do not amaze but confuse. We may succeed in raising test scores, but we will fail to teach them that reading can be transformative and that it belongs to them.
【小題1】The underlined words in Paragraph 1 probably mean that a book helps to________.

A.realize our dreams
B.give support to our life
C.smooth away difficulties
D.a(chǎn)wake our emotions
【小題2】Why were the students able to understand the novel Of Mice and Men?
A.Because they spent much time reading it.
B.Because they had read the novel before.
C.Because they came from a public school.
D.Because they had similar life experiences.
【小題3】The girl left the selective high school possibly because ________.
A.she was a literary-minded girl
B.her parents were immigrants
C.she couldn’t fit in with her class
D.her father was then in prison
【小題4】To the author’s surprise, the students read the novels ________.
A.creativelyB.passively C.repeatedlyD.carelessly
【小題5】The author writes the passage mainly to ________.
A.introduce classic works of literature
B.a(chǎn)dvocate teaching literature to touch the heart
C.a(chǎn)rgue for equality among high school students
D.defend the current testing system

The worst earthquake in 40 years shook South Asia on Sunday, starting with horrible waves that swept entire villages into the sea. At least 20,000 people in six countries were killed in the disaster, and millions were left homeless.
The quake shook deep beneath the Indonesian island of Sumatra. It was felt more than 3000 miles away in East Africa, where heavy tides kept fishermen at home and resorts(度假勝地)closed.
It was as if the sea had struck the land. Residents of Sri Lanka, a small island country off the coast of India, ran to the hills to find safety from the tsunami. Many took their radios, televisions, and other valuables with them. The disaster hit Sri Lanka hardest. Of its 20million people, 1 million lost their homes, and 10000 died.
“The water simply raised itself up and huge waves came ashore,” wrote eye-witness(目擊者)Peter Thomas from India. “It was moving very fast. The force broke the glass walls of a restaurant on the beach here and damaged hundreds of boats.”
In some places, the tsunami struck with no warning. “The weather was fine with no clouds,” wrote an eye-witness in Indonesia. “Suddenly the seawater just hit the city. In some parts the water was up to chest level.”
A massive(大眾的)effort to help the affected countries is already underway. Leaders from around the world have promised to help, and teams of aid workers and doctors are rushing to the sea. “The United States stands ready to offer all the help to those nations most affected.” Said White House spokesman Trent Duffy. Organizations from the Red Cross to the International Monetary Fund have started fund-raising(籌款)drives to make up the costs of rebuilding.
【小題1】 The underlined word “tsunami” in Paragraph 5 can probably be replaced by “__________.”

A.fierce windB.heavy rainC.terrible stormD.large waves

ple — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可樹)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Eu??rope, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish peo??ple starved when the crop failed during the "Potato Famine (饑荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.
