问答题 COEVOLUTION Coevolution is the joint evolution of two species that are dependent on each other. Each species influences the other, so they evolve at the same time. Coevolution is a result of complex interactions involving mutual evolutionary changes. A change in one species acts as a selective force on another species, which adapts in response. The adaptation in the second species, in turn, is a selective force on the first species. Hence, the two species trade adaptations and evolve together. Coevolution often occurs when both species receive a benefit, such as a higher rate of survival. Now cover the passage and listen to the recording. When you hear the question, begin preparing your response. Use the examples from the lecture to explain the concept of coevolution.

问答题Read the passage and answer the question below. Then listen to the recording and answer the rest of the questions. The discovery of penicillin and other antibiotic drugs was the most dramatic medical development of the twentieth century. These new drugs quickly became known as "wonder drugs" because of their ability to cure major forms of bacterial infection quickly and completely. Antibiotics made it possible for hospital patients to survive during and after surgery. No longer did patients have to depend largely on their body's own immune system to fight off infections. These infections could be attacked directly with antibiotics. Antibiotics have given the medical profession powerful tools to fight a wide range of specific diseases. The development of antibiotics in the 1930s rested on the belief in the existence of certain chemicals that had the power to destroy specific microorganisms without injuring the human body at the same time. Advances in chemistry and in the study of bacteria quickened the discovery of such chemical wonders. The development of penicillin in the 1940s laid the foundation for even more powerful weapons against specific diseases. Since that time, researchers have identified hundreds of antibiotic substances that are effective against one or another type of bacteria. Among the most spectacular effects of antibiotics are reductions in the number of deaths from pneumonia and tuberculosis. Penicillin, one of the earliest of the wonder drugs, is a highly successful cure for pneumonia. Just ten thousand units of penicillin four times a day will be enough to cure bacterial pneumonia in most patients. Another important antibiotic is streptomycin, which is potent against tuberculosis. As a result, tuberculosis is no longer the life-threatening illness it once was. 1. What is the main idea of the passage? What points support the main idea? Now listen to the recording.

问答题A Letter from a Student I have noticed at least one serious problem on our campus: there is a serious lack of study areas. Dorm rooms are too small and too noisy. The library is cold, the sound echoes, and there is too much foot traffic. Classrooms are usually holding classes. I think the university should provide students with a study lounge featuring tables, chairs, and maybe some couches. This way we would have a quiet place to study. If there were a few private rooms there, students from the same class could gather together and discuss their study. Question: The man expresses his opinion about the proposal given by a student suggesting that the school establish a study lounge for students. State his opinion and explain the reasons he gives for holding that opinion. Now hear a conversation between two students.

问答题学生的论文写得不错，教英文的老师认为他可以去兼职writing tutoring（有题，老师叫学生来的目的：encourage学生接受一份工作）。学生认为自己是biology专业的，上英语课只不过为了提高自己，应该不能胜任。老师说教写作的范围很广，他正好可以教biology专 业学生的写作。他问有没有培训，老师说当然需要，教写作不仅是会写，还有教学方法和技巧的培训，比如问题引导和建议。然后学生就自己假设了一个教学情景， 老师说就是这么回事。然后学生还有疑问，说这样就可以了？老师说当然不止，还得有一个培训，经过老师的指导，学生第一次上课还会有老师听课，查看教学效 果，再根据情况提升（有题，5选3）。学生继续问细节，老师说你知不知道某个人，她就是在教授写作。学生说认识，一块上课的。老师说你去找她问吧，她对具体细节肯定了解，好像现在在图书馆（有题，老师提这个人干什么）。
