What does Wordsworth mean by "habit rules the unreflecting herd" (Lines 2-3, Para. 1)?
A.The herd is not used to reflecting.
B.The wild animals have no choice to form their habits.
C.Habit is characterized by being mechanical.
D.Habits are changeable.

4、Questions are based on the following passage.
  It was once thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic.Today,we know that although these are the areas with the worst air pollution,the problem is literally worldwide.On several occasions over the past decade,a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings
  even in rural areas away from any major concentration of manufacturing and automobile traffic.In fact, the very climate of the entire earth may be affected by air pollution.
  Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil.is creating a“greenhouse effect”一holding in heat reflected from the earth and raising the world’s average temperature.If this view is correct and the world’s temperature is raised only a few degrees。much of the polar ice cap will melt and cities such as New Y0rk,Boston,Miami,and New Orleans will be under water.
  Another view,less widely held,is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature—a result that would be equally disastrous.A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas.
  At present we do not know for sure that either of these conditions will happen,though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely.Perhaps,if we are very lucky,the two tendencies will offset each other and the world’s temperature will
  stay about the same as it is now.
  According to the passage,people today think that air pollution________.
A.exists merely in urban and industrial areas
B.may have an effect on the entire earth
C.causes widespread damage in the countryside
D.is not so serious as it used to be

5、There was a knock at the door.It was the second time someone___________(那晚打扰我). 

6、Scientists have devised a way to determine roughly where a person has lived using a strand (缕) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims.
The method relies on measuring how chemical variations in drinking water show up in people’s hair.
“You’re what you eat and drink, and that’s recorded in your hair,” said Thure Ceiling, a geologist at the University of Utah.
While U.S. diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move.
Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes (同位素). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy or the map by testing 200 hair samples collected from 65 barber shops.
They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems.
“It’s not good for pinpointing (定位),” Ceding said. “It’s good for eliminating many possibilities.”
Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.
The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.
When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months.
She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.
“It’s still a substantial area,” Park said. “But it narrows it way down for me.”
注意:此部分试题请在答题卡2上作答。
What is the scientists’ new discovery?
A.One’s hair growth has to do with the amount of water they drink.
B.A person’s hair may reveal where they have lived.
C.Hair analysis accurately identifies criminal suspects.
D.The chemical composition of hair varies from person to person.
