第8题
The challenge of predicting organismal responses to global climate change is difficult.
Partly, this is due to the fact that there are more studies of short-term, individual organism responses than there are of long-term, systemwide studies.
It is extremely difficult, both monetarily and physically, for scientists to conduct field studies at spatial and temporal scales that are large enough to include all the components of real-world systems, especially ecosystems with large, freely ranging organisms.
One way paleobiologists try to get around this limitation is to attempt to reconstruct past climates by examining fossil life.
Look at the four squares[
]that indicate where the following sentence can be added to the passage. Much of this work depends on the assumption that life forms adapted to a particular climate in the present were adapted to the same type of climate in the past. Where would the sentence best fit？

This is migration. There are many things which help animals to migrate. Birds and other animals have a body clock which tells them about changes in temperature and periods of light. Birds and some insects use their eyes to measure and compare the position of the sun from different place.
Many people now believe magnetism is very important. The earth itself is a magnet and every kind of life is affected in some way by its magnetic, fields.
But there are still many questions without answers, for example, the migration of eels. European eels travel down their rivers and into the Atlantic Ocean. They then swim 5600 kilometers to the Sargasso Sea, where they lay their eggs. The eels then die. The baby eels are carried by the Gulf Stream to Europe, a journey which takes two and a half years. They swim back up the rivers. There they live for about ten years before the return journey to the Atlantic. How do they do this？ We know what happens to the eels but not how or why.
"Migration" in this passage means
A．the seasonal moving of creatures.
B．settling down in a new place.
C．the activity controlled by magnetism.
D．knowing where one is going and making no mistakes.
第10题
No wooded landscape we see today has been forest for all time. Plants have minimum requirements of temperature and moisture and, in ages past, virtually every part of Earth's surface has at some time been either too dry or too cold for plants to survive. However, as soon as climatic conditions change in favour of plant life, a fascinating sequence of changes occurs, called a primary succession.
First to colonize the barren land are the lowly lichens, surviving on bare rock. Slowly, the acids preduced by these organisms crack the rock surface, plant debris accumulates, and mosses establish a shallow root-hold. Ferns may follow and, with short grasses and shrubs, gradually form. a covering of plant life. Roots probe even deeper into the developing soil and eventually large shrubs give way to the first trees. These grow rapidly, cutting off sunlight from the smaller plants, and soon establish complete domination-closing their ranks and forming a climax community which may endure for thousands of years.
Yet even this community is not everlasting. Fire may destroy it outright and settlers may cut it down to gain land for pasture or cultivation. If the land is then abandoned, a secondary succession will take over, developing nmch faster on the more hospitable soil. Shrubs and trees are among the early invaders, their seeds carried by the wind, by birds and lodged in the coats of mammals.
For as long as it stands and thrives, the forest is a vast machine, storing energy and many elements essential for life.
What does the forest strike mankind as permanent？
A．The trees are in community.
B．The forest is renewed each season.
C．Man's life is short in comparison.
D．It is an essential part our lives.
