单选题How can English teachers accelerate the language learning of their students? One way is to teach students how to learn more effectively and efficiently. Learning strategies are "Procedures or techniques that learners can use to facilitate a learning task. " Instructing students of English in learning strategies can help them become better learners. In addition, skill in using learning strategies assists students in becoming independent, confident learners. Finally, students become more motivated as they begin to understand the relationship between their use of strategies and success in learning English. Students need to develop an awareness of the learning process and strategies that lead to success. Students who reflect on their own thinking are more likely to engage in pianning how to proceed with a learning task, monitoring their own performance on an ongoing basis, finding solutions to problems encountered, and evaluating themselves upon task completion. These activities may be difficult for students accustomed to having a teacher who solves all their learning problems and is the sole judge of their progress. Teachers need to encourage students to rely more on themselves. Because learning strategies are mental processes with few observable manifestations, teachers need to find ways to make the strategies as concrete as possible. When students are able to use the strategies their teachers have taught them, and to do so without prompting, then they need to explore new strategies, new applications, and new opportunities for self-regulated learning.

单选题Every artist knows in his heart that he is saying something to the public. Not only does he want to say it well, but he wants it to be something which has not been said before. He hopes that the public will listen and understand--he wants to teach them, and he wants them to learn from him. What visual artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experiences into shapes and colors, not words. (40) They seem to feel that a certain selection of shapes and colors, out of the countless billions possible, is exceptionally interesting for them and worth showing to us. Without their work we would never have noticed these particular shapes and colors, or have felt the delight which they brought to the artist. Most artists take their shapes and colors from the world of nature and from human bodies in motion and stillness; their choices indicate that these aspects of the world are worth looking at, that they contain beautiful sights. Contemporary artists might say that they merely choose subjects that provide an interesting pattern, and that there is nothing more in it, yet even they do not choose entirely without reference to the character of their subjects. If one painter chooses to paint an injured leg and another a lake in moonlight, each of them is directing our attention to a certain aspect of the world. Each painter is telling us something, showing us something, emphasizing something--all of which means that, consciously or unconsciously, he is trying to teach us.
