Most people who travel long distances complain of jetlag (喷气飞行时差反应). Jetlag makes business travelers less productive and more prone (21) making mistakes. It is actually caused by (22) of your "body clock"—a small cluster of brain cells that controls the timing of biological (23) . The body clock is designed for a (24) rhythm of daylight and darkness, so that it is thrown out of balance when it (25) daylight and darkness at the "wrong" times in a new time zone. The (26) of jetlag often persist for days (27) the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is (28) that is based on proven (29) pioneering scientific re- search. Dr. Martin Moore-Ere has (30) a practical strategy to adjust the body clock much sooner to the new time zone (31) controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates (32) of the discomfort of jetlag. A successful time zone shift depends on knowing the exact times to either (33) or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule (34) light exposure depends a great deal on (35) travel plans. Data on a specific flight itinerary (旅行路线) and the individual’s sleep (36) are used to produce a Trip Guide with (37) on exactly when to be exposed to bright light. When the Trip Guide calls (38) bright light you should spend time outdoors if possible. If it is dark outside, or the weather is bad, (39) you are on an aero plane, you can use a special light device to provide the necessary light (40) for a range of activities such as reading, watching TV or working. 40().

In The Sorrows of Empire, Chalmers Johnson advances the disturbing claim that the United States’ Cold War-era military power and far-flung base system have, in the last decade, been consolidated in a new form of global imperial rule. The United States, according to Johnson, has become "a military juggernaut intent on world domination."Driven by a triumphalist ideology, an exaggerated sense of threats, and a self-serving military- industrial complex, this juggernaut is tightening its grip on much of the world. The Pentagon has re- placed the State Department as the primary shaper of foreign policy. Military commanders in regional headquarters are modern-day proconsuls, warrior-diplomats who direct the United States’ imperial reach. Johnson fears that this military empire will corrode democracy, bankrupt the nation, spark opposition, and ultimately end in a Soviet-style collapse.In this rendering, the American military empire is a novel form of domination. Johnson de- scribes it as an "international protection racket: mutual defense treaties, military advisory groups, and military forces stationed in foreign countries to" defend" against often poorly defined, overblown, or nonexistent threats." These arrangements create "satellites"—ostensibly independent countries whose foreign relations revolve around the imperial state.Johnson’s previous polemic, Blowbaek, asserted that post-1945 U.S. spheres of influence in East Asia and Latin America were as coercive and exploitative as their Soviet counterparts. The Sorrows of Empire continues this dubious line. Echoing 1960s revisionism, Johnson asserts that the United States’ Cold War security system of alliances and bases was built on manufactured threats and driven by expansionary impulses. The United States was not acting in its own defense; it was exploiting opportunities to build an empire. The Soviet Union and the United States, according to this argument, were more alike than different: both militarized their societies and foreign policies and expanded outward, establishing imperial rule through "hub and spoke" systems of client states and political dependencies.Unfortunately, Johnson offers no coherent theory of why the United States seeks empire. At one point, he suggests that the American military empire is founded on "a vast complex of interests, commitments, and projects." The empire of bases has become institutionalized in the military establishment and has taken on a life of its own. There is no discussion, however, of the forces within U. S. politics that resist or reject empire. As a result, Johnson finds imperialism everywhere and in everything the United States does, in its embrace of open markets and global economic integration as much as in its pursuit of narrow economic gains. It can be inferred from the passage that the Soviet collapse because of().

A. the overexpansion of military into polities.
B. the rebellion of the civil.
C. the inability of the government.
D. the disappearance of democracy.
