4. Intricately intertwined with(与……错综交织) self-esteem and inhibition and risk-taking, the construct of anxiety, as it has been studied in the psychological domain(领域), plays an important affective role in second language acquisition. Anxiety is almost impossible to define in a simple sentence. It is associated with feelings of uneasiness, frustration, self-doubt, apprehension(恐惧), or worry. Scovel defined anxiety as “state of apprehension, or vague fear…” We all know what anxiety is and we all have experienced feelings of anxiousness. How does this construct relate to second language learning? Any complex task we undertake can have elements of anxiety in it, aspects in which we doubt our own abilities and wonder if we will indeed succeed. Second language learning is no exception to a long list of complex tasks that are susceptible(易受感染的) to our human anxieties.The research on anxiety suggests that, like self-esteem, anxiety can be experienced at various levels. At the deepest, or global level, trait anxiety is a more permanent predisposition(倾向) to be anxious. Some people are predictably and generally anxious about many things. At a more momentary, or situational level, state anxiety is experienced in relation to some particular event or act. As we learned in the case of self-esteem, then, it is important in a classroom for a teacher to try to determine whether a student’s anxiety stems from a more global trait or whether it comes from a particular situation at the moment.Trait anxiety, because of its global and somewhat ambiguously defined nature, has not proved to be useful in predicting second language achievement. However, recent research on foreign language anxiety, as it has come to be known, focuses more specifically on the situational nature of state anxiety.(5分)4.1 The passage mainly talks about ______.(1分)A. anxietyB. inhibitionC. risk-takingD. self-esteem
3.Friction is a force which opposes motion. Much of the energy supplied to a complicated machine with many moving parts is wasted in overcoming this opposition. The energy is converted into useless heat. The amount thus lost can be considerably reduced and the life of the machine prolonged by careful lubrication. This reduction improves the efficiency of the machine. Another way in which friction is reduced is to substitute roller or ball bearings for the earlier type of bearing, in which the surfaces in contact move by sliding. Bearings of these later types are used very extensively in many kinds of modern machinery.It must not be assumed, however, that friction is always a disadvantage. In many instances it is highly important. Belts are often used in conveying power from one machine to another. In the absence of friction, this could not be done. The driving wheel would not run the belt, neither would the belt run the wheel to driver. Without friction, then, belted machinery could not be used. Again in the case of all motor vehicles, friction is essential in the operation of the brake. Were there no friction, there could be no brake. But even this illustration does not give an adequate picture of the importance of friction. The vehicle could not even be started if it were not for the friction exerted between the tires and the road. Nails hold in wood, and screws hold in either wood or metal by reason of friction, without which they would be useless. Walking is difficult enough on an icy pavement, but it would be wholly impossible if there were no friction at all between the shoe and the pavement.(5分)3.1Friction arises when____.(1分)A. an opposing force of motion existsB. the energy is wastedC. everything is motionlessD. a complicated machine is supplied with energy
