Certain animals and plants develop characteristics that help them deal with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the gradual development of more and more organisms(small living things)that are better fitted to their environments.
Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class (kind ) . A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals (无机化学物). It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plants have.
Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near.
Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions.
40. Some plants and animals develop superior characteristics so that they may .
A. help others of their kind get food, shelter and other things needed
B. survive even in extremely severe conditions
C. become better adapted to the environments than others of their kind
D. result in the evolution and production of more intelligent organisms
41. In the first paragraph, the word "environments" could best be replaced by .
A. contexts B. surroundings C. neighbors D. enemies
42. It can be inferred from this passage that the feathers of a bird are colored .
A. to frightened its enemies. B. to attract its enemies
C. to adjust its body heat D. to match its environment
43. Which of the following is not directly mentioned?
A. A living thing may adapt in its structure.
B. An organism may adapt in its function.
C. A living creature may adapt in its genetic makeup.
D. A living organism may adapt in its sleeping habit.

阅读理解: 阅读下列短文, 从所给的四个选项中, 选出最佳答案。
Think for a moment about the teachers you have had at school or at university. Which one did you like best? And why? Were the teachers you liked best also the ones who were the best teachers, in your opinion? Before you read any further, consider for a moment the qualities that make a teacher outstanding. (杰出的;出类拔萃)
Some very common answers to this question are that teachers need to love their students, that they need to have an expert (专家的) knowledge of their subjects, and that they should devote themselves completely to their work. All of these ideas are, of course, true to a certain extent (程度) but they are perhaps a little too simple.
It is impossible for anyone to love everyone they know, and teachers deal with a very large number of students over the years. On the other hand, teachers should certainly be able to make their students feel that they are interested in them as people and in the development of both their brains and their characters. A deep knowledge of the subject is especially important, but equally (同样的) important is the ability to pass that knowledge on to the students effectively—a teacher needs to be trained in the skills of teaching. These skills include how to explain ideas in a clear way, how to help students to use the knowledge they are given, how to control a class and so on. Finally, teachers have to devote a lot of time and energy to their work, of course. However, they are also models that their students must follow; so it is important that they should be well-balanced people with interests outside their school work— family, friends, hobbies, and so on. A teacher who only lives for work is likely to become too narrow-minded.
(1)The writer suggests that you think about the teachers who have taught you at school in order that __________.
[ ]
A. you may love them better than before
B. you'll get something you can write about them
C. you might know the qualities that a good teacher should have
D. you might get something for which you will praise them
(2)It is impossible for every teacher ________ according to the article.
[ ]
A. to have a good knowledge of the subject he teaches
B. to have ways to pass the knowledge of his subjects on to his students effectively
C. to be a good example for his students to follow
D. to love all the students he has taught or is teaching
(3)In the sentence "teachers should certainly be able to make their students feel that they are interested in them as people…" "they" and "them" refer to ___________.
[ ]
A. teachers and teachers B. students and students
C. teachers and students D. students and teachers
(4)The skills of teaching include __________.
[ ]
A. how to explain ideas in a clear way
B. how to devote a lot more time to their work
C. how to control a class
D. A and C
(5)A teacher who ___________ is likely to be too narrow-minded.
[ ]
A. are well-balanced people with a lot of interests
B. are interested not only in class but also in outside their school work
C. only lives for his work
D. have other interests besides his teaching
