1．The theory of learning is referred to as behaviorism, which has three major stages, “stimulus, response, and reinforcement”

2．The behaviorist theory of language learning

is that language is learned by constant repetition and the reinforcement of the teacher

3．The term cognitivism is often used loosely

to describe methods in which students are asked to think rather than simply repeat.

4．There are a variety of elements that contribute to the qualities of a good language teacher. These elements can be categorized into 3 groups: ethic devotion, professional qualities

and personal styles.

5. Three different views on language are the structural view, the functional view and the interactional view. 文档从网络中收集，已重新整理排版.word版本可编辑.欢迎下载支持.

Thermal compression is the term used to describe the appl ication of a steamjet ejector or thermocompressor to an evaporator in order to increase the steameconomy. A typical system is illustrated in Figure 18-1. Steam jet thermo-compressors can be used with either single or multiple-effect evaporators. As arule-of-thumb, the addition of a thermocompressor will provide an improved

Thermocompressors have low thermal efficiencies which further diminish when the jet is not operated at its design point. In typical operation, thermocompressors can entrain one unit of vapor per unit of motive steam. Thermocompressors are available in a wide range of materials of con- struction and exhibit a wide range of design operating conditions. They should be considered only when high pressure steam is available and the evaporator can be operated with low pressure steam. Motive-steam pressures greater than 60 psig usually are required to justify the use of thermocompressors. Space limi- tations favor thermal compression. Steam condensate from thermal compression systems often is contaminated with product traces and may have to be treated before being returned to the steam generator. THERMOCOMPRESSOR OPERATION The thermocompressor design is very similar to that of steam jet ejectors used for producing vacuum. The standard types of ejectors used for thermal compression are shown in Figure 18-2. Each ejector consists of three basic

Writing task 1:

1. Watch the video, and write a summary which should include:

1) The theme of the song

2) What happened in the end

2. Make some comments on deforestation.

Tips: 采伐森林deforestation; 拯救世界heal the world

Sample Writing：

The song has an environmental theme, showing images of animal cruelty,

pollution and war. Jackson and the world's people unite in a spiritual chant—"Earth

Song"—which summons a force that heals the world. Using special effects, time is

reversed so that life returns, war ends and the forests regrow.

With more and more trees cut down, many kinds of birds or animals have no

homes and become extinct, lots of good land become deserts and the soil will be

washed away more easily ,which will eventually lead to floods and droughts.

Meanwhile, the power of the surface of the earth to control the climate is being
