Sequoyah was a young Cherokee Indian, son of a white trader and an Indian Squaw (北美印第

Sequoyah was a young Cherokee Indian, son of a white trader and an Indian Squaw (北美印第安女人). At an early age, he became fascinated by "tile talking leaf", an expression that he used to describe the white man’s written records. Although many believe this "talking leaf" to be a gift from tile Great Spirit, Sequoyah refused to accept that theory. Like other Indians of tile period, he was illiterate, but his determination to remedy tile situation led to the invention of a unique 86 character alphabet based on the sound pat- terns that he heard.

His family and friends thought him mad, but while recuperating (恢复) from a hunting accident, he diligently and independently set out to create a form. of communication for his own people as well as for other Indians. In 1821, after twelve years of work, he had successfully developed a written language that would en- able thousands of Indians to read and write.

Sequoyah's desire to preserve words and events for later generation has caused him to be remembered among the important inventors. The giant redwood trees of California, called "sequoias (红杉)" in his honor, will further imprint his name in history.

What is the most important reason that Sequoyah will be remembered? ()

A.California redwoods were named in his honor.

B.He was illiterate.

C.He created a unique alphabet.

D.He recovered from his madness and helped mankind.

"A rolling stone gathers no moss (苔藓) ," but there is one living animal that does gather

"A rolling stone gathers no moss (苔藓) ," but there is one living animal that does gather moss, the three-toed sloth (树獭) of South America. This slowest-moving member of the animal kingdom is so inactive that moss actually gathers on its body and turns it green strange as it seems!

Most of the sloth's life is spent motionless, hanging upside down from a limb. And that is the way its hair grows. Long and coarse, the strands (串) from receptacles (花托) for the damp jungle algae (水藻) that turn the brown fur a mossy green. Actually this moss helps the animal survive because it serves as a per- fect camouflage against the leaf trees and hides the sloth from the jungle's swift-moving hunters. The sloth would have little chance of survival on the ground. With long, curved claws hooked over the limb of a leafy tree, it spends the long hot hours during the day drowsing and eating. Inch by inch, it strips the leafy limbs bare and crawls Slowly down the trunk to find a new dining spot, but only at night.

In addition to looking rather like a vegetable, the sloth is a strict vegetarian. Running out of its favorite leaf is about the only thing that will make a sloth move. Then its appetite may even force the animal into swimming a stream to reach a juicy succulent(多汁的值物). It will also force it into fighting to keep the tree all to itself. The sloth is lazy and prefers to be alone, but it will tolerate its own relatives!

A suitable title for this passage might be ______. ()

A.Wild Animals

B.Animal Kingdom

C.Moss Growth

D.The Lazy Animal

"The essential qualities of a true Pan-Americanism", remarked Franklin Roosevelt in 1933,"

"The essential qualities of a true Pan-Americanism", remarked Franklin Roosevelt in 1933, "must be the same as those which constitute a good neighbour, namely mutual understanding and… a sympathetic appreciation of the other's point of view." That is advice which the United States would do well to heed in its relations with its immediate neighbours, Canada and Mexico. Most Americans may not be aware of it, but frustrations and resentments are building just across their borders to both south and north.

Of course, neighbourly ties in North America are closer than in Roosevelt's day. Under the North American Free-Trade Agreement (NAFTA), trade among the three countries has more than doubled since 1994 and cross-border investment climbed even faster. In the aftermath of the terrorist attacks of September 11th 2001, the United States moved quickly to sign "smart border" agreements with both Canada and Mexico, to try to ensure that the demands of security did not interrupt trade. By the standards of much of the 20th century, political ties between the United States and Mexico are warm.

Yet go to either border and you wouldn't know all this. Fed up with the flow of illegal migrants from the south, the governors of Arizona and New Mexico this month declared a state of emergency. Violence between drug gangs recently led the United States temporarily to close its consulate in Nuevo Laredo, the busiest border-crossing point. The American ambassador bluntly criticises Mexico for its failure to prevent drug-related violence along the border. That has prompted retaliatory verbal blasts from Mexican officials.

Canada's mood is not much more cordial. Since September 11th, Canadians and Americans alike have become less keen on popping over what they liked to call " the world's longest undefended border" for shopping or recreation. Canadians increasingly disagree with Americans over matters as varied as the Iraq war and gay marriage. They are disillusioned with NAFTA, claiming it has failed to prevent the United States from unlawfully punishing their exports of, for example, lumber.

So what? Friction is in the nature of international relations, and the problems on the northern border are different from those in the south. Yet there is a common denominator. Americans tend to see security, migration, drugs, even trade, as domestic political issues. But so they are for Canada and Mexico too. Like it or not, Americans rely on their neighbours for prosperity, energy and help with security. It behoves all three countries to show some "sympathetic understanding".

It can be inferred from the first paragraph that______.

A.the essential qualities of a true Pan-Americanism were defined by Franklin Roosevelt

B.mutual understanding is one of the most far-reaching elements in North America

C.few Americans may be aware of others'point of view

D.America's friendship with Canada and Mexico risks going sour

When Ted Kennedy gazes from the windows of his office in Boston, he can see the harbor's "
Golden Stairs', where all eight of his great-grandparents first set foot in America. It reminds him, he told his Senate colleagues this week, that reforming America's immigration laws is an "awesome responsibility". Mr. Kennedy is the Democrat most prominently pushing a bipartisan bill to secure the border, ease the national skills shortage and offer a path to citizenship for the estimated 12m illegal aliens already in the country. He has a steep climb ahead of him.

As drafted, the bill seeks to mend America's broken immigration system in several ways. First, and before its other main provisions come into effect, it would tighten border security. It provides for 200 miles (320 km) of vehicle barriers, 370 miles of fencing and 18,000 new border patrol agents. It calls for an electronic identification system to ensure employers verily that all their employees are legally allowed to work. And it stiffens punishments for those who knowingly hire illegals.

As soon as the bill was unveiled, it was stoned from all sides. Christans, mostly Republicans, denounced it as an "amnesty" that would encourage further waves of illegal immigration. Tom Tancredo, a Republican congressman running for president (without hope of success) on an anti-illegal-immigration platform, demanded that all but the border-security clauses be scrapped. Even these he 'derided as "so limited it's almost a joke". Conservative talkradio echoed his call. No one is seriously proposing mass deportation, but Mr. Tancredo says the illegals will all go home if the laws against hiring them are vigorously enforced.

Most labor unions are skeptical, too. The AFL-CIO denounced the guest-worker program, which it said would give employers "a ready pool of labor that they can exploit to drive down wages, benefits, health and safety protections" for everyone else. Two Democratic senators tried to gut the program. One failed to abolish it entirely; another succeeded in slashing it from 400 000 to 200,000 people a year.

Employers like the idea of more legal migrants but worry that the new system will be cumbersome. Many object to the idea that they will have to check the immigration status of all their employees. The proposed federal computer system to sort legal from illegal workers is bound to make mistakes. Even ff only one employee in a hundred is falsely labeled illegal, that will cause a lot of headaches. And the points system has drawbacks, too. Employers are better placed than bureaucrats to judge which skills are in short supply. That is why the current mess has advantages—illegal immigrants nearly always go where their labor is in demand.

Other groups have complaints, too. Immigrant-rights groups say that the path to citizenship would be too long and arduous and too few Hispanics would qualify. Nancy Pelosi, the Democratic speaker of the House, fretted that the new stress on skills would hurt families, adding that her party is "about families and family values". Some people worry that House Democrats will kill it to prevent Mr. Bush from enjoying a domestic success.

Despite the indignation, public opinion favors the underlying principles. At least 60% of Americans want to give illegals a chance to become citizens if they work hard and behave.

Ted Kennedy is mentioned in the first paragraph to

A.introduce the main topic of immigration law reforming.

B.remind the Senate that they have an awesome responsibility.

C.stress the importance of securing the border and easing skills shortage.

D.emphasize the fact that even a Senator is a descendant of immigrants.
