第2题：实验发现，孕妇适当补充维生素D可降低新生儿感染呼吸道合胞病毒的风险。科研人员检测了156名新生儿脐带血中维生素D的含量，其中54%的新生儿被诊断为维生素D缺乏，这当中有12%的孩子在出生后一年内感染了呼吸道合胞病毒，这一比例远高于维生素D正常的孩子。 　　以下哪项如果为真，最能对科研人员的上述发现提供支持？上述实验中，54%的新生儿维生素D缺乏是由于他们的母亲在妊娠期间没有补充足够的维生素D造成的。
A、孕妇适当补充维生素D可降低新生儿感染流感病毒的风险，特别是在妊娠后期补充维生素D，预防效果会更好。
B．上述实验中，46%补充维生素D的孕妇所生的新生儿有一些在出生一年内感染呼吸道合胞病毒。
C．科研人员实验时所选的新生儿在其他方面跟一般新生儿的相似性没有得到明确验证。
D．维生素D具有多种防病健体功能，其中包括提高免疫系统功能、促进新生儿呼吸系统发育、预防新生儿呼吸道病毒感染等。
E．上述实验中，54%的新生儿维生素D缺失是由于他们的母亲在妊娠期间没有补充足够的维生素D造成的。

第3题：September 11 should have driven home a basic lesson for theBush administration about life in an interconnected world: misery abroad threatens security at home. It is no coincidence that OsamaBin Laden found warm hospitality in the Taliban’sAfghanistan, whose citizens were among the most impoverished and oppressed on earth. If the administration took this lesson seriously, it would dump the rules of realpolitik that have governed U.S. foreign aid policy for 50 years. Instead, it is pouring money into an ally of convenience, Pakistan, which is ultimately likely to expand the ranks of anti-American terrorists abroaD、
To enlist Pakistan in the fight against the Taliban, theBush administration resurrected theCold War tradition of propping up despotic military regimes in the name of peace and freedom. Its commitment of billions of dollars to Pakistan since September 11 will further entrench the sort of government that has made Pakistan both a development failure and a geopolitical hotspot for decades. Within Pakistan, the aid may ultimately create enough angry young men to make upA1 Qaeda’s losses inAfghanistan. In SouthAsia as a whole, the cash infusion may accelerate a dangerous arms race with Indi
A、
Historically, the U.S. government has cloaked aid to allies such as Pakistan in the rhetoric of economic development.As aCold War ally, Pakistan received some $ 37 billion in grants and loans from the West between 1960 and 1990, adjusting for inflation.And since September 11, the U.S. administration has promised more of the’ same. It has dropped sanctions imposed after Pakistan detonated a nuclear bomb in 1998, pushed through a $1.3 billion IMF loan for Pakistan, and called for another $2 billion from the WorldBank and theAsianDevelopmentBank. TheBush administration is also, ironically, pressing allies to join it in canceling or rescheduling billions of dollars of old (and failed) loans that were granted in past decades in response to similar arm-twisting.
Despite--even because of--all this aid, Pakistan is now one of the most indebted, impoverished, militarized nations on earth. The causes of Pakistan’s poverty are sadly familiar. The government ignored family planning, leading to population expansion from 50 million in 1960 to nearly 150 million today, for an average growth rate of 2.6 percent a year. Foreign aid meant to pave rural roads went into unneeded city highways--or pockets of top officials.And the military grew large, goaded by a regional rivalry with India that has three times bubbled into war. The result is a government that, as former WorldBank economist WilliamEasterly has observed, "cannot bring off a simple and cheap measles (麻疹) vaccination (预防接种) program, and yet...can build nuclear weapons.\
It implies in the passage that ______.

A、the U.S. government has been helping Pakistan’s economic development
B、the U.S. approved Pakistan’s detonating nuclear bomb
C、the Pakistan government is corrupt
D、the Pakistan government didn’t pay much attention to family planning

Passage 5
The human being longs for a sense of being accomplished, of being able to do things, with his hand, with his mind, with his will.Each of us wants to feel he or she has the ability to do {{U}} (1) {{/U}} that is meaningful and that serves as a {{U}} (2) {{/U}} to our inherent abilities.
It is easiest to see this {{U}} (3) {{/U}} the craftsman who lovingly shapes some cheap material into an object that may be either useful or beautiful or {{U}} (4) {{/U}}.

Our own research in hospitals suggests that {{U}} (8) {{/U}} the housekeeping and laundry staffs take pride in the {{U}} (9) {{/U}} that in their own ways they are helping to cure sick people--and thus accomplishing a good deal.
We’re often misled by the complaints {{U}} (10) {{/U}} difficult work; deep {{U}} (11) {{/U}} most people regard their own capacity to conquer the tough job as the mark of their own unique {{U}} (12) {{/U}}Complaining is just {{U}} (13) {{/U}} of working.After all, how {{U}} (14) {{/U}} do you know who you are, except as you can demonstrate the ability of your {{U}} (15) {{/U}} to control you limbs and hands and words You are, {{U}} (16) {{/U}} significant measure, what you can do.
Some are deceived into thinking that people like to store up {{U}} (17) {{/U}}, to rest and save {{U}} (18) {{/U}} as much as possible. Just the {{U}} (19) {{/U}}. It is energy {{U}} (20) {{/U}} that is satisfying.
