Subject: English Pronunciation for Communication Purpose: The students will learn stressed syllables & unstressed syllables in English. Objectives: Students will be able to: 1. Define - in their own words a definition for stressed syllables & unstressed syllables. It is a revision and therefore, easy for most of the students; 2. Compare – based on the understanding of the basic concept, compare stressed and unstressed syllables in words and sentences;

Date: Sept.16-20 Class: Classes 1, 2 & 3, Grade 2002 Subject: English Pronunciation for Communication Purpose: The students will learn some basic concepts in English pronunciation. We are going to learn something about syllables, stress and rhythm in English. At the same time, they will learn to say greetings and farewell with appropriate pronunciation and intonation in English

In addition to the 'pure vowels' (ones where the tongue positioning is fairly static) shown above there is also the set of vowel diphthongs. These are effectively long vowels during which the tongue moves to produce a definite change of quality during the sound. In phonetic transcription we usually use a pair of linked symbols for each diphthong - one indicating the quality of the sound at the start of the vowel, and the other indicating its quality as it ends. Examples of diphthongs are found in words like 'boy', 'hear', 'may', 'my

1 Introduction Electrostatic thrusters (“ion engines”) are the best developed type of electric propulsion device, dating in conception to the ‘50’s,(1) and having been demonstrated in space in 1964 on a suborbital flight of the SERT I spacecraft(2). The early history

2. Money plays a key role in the performance of the economy. The amount of money in the economy should not be too little or too much, but just“right?

The only practical way to accelerate something in free space is by reaction. The idea is the same as in air breathing propulsion (to push something backwards) but in rockets the “something” must be inside and is lost. Here is a revealing derivation of the thrust equation for vacuum:

The result appears to be trivial, but it is not. Notice that the “velocity increment” ∆V is actually equal to the decrease in orbital velocity. The rocket is pushing forward, but the velocity is decreasing. This is because in a r-2 force field, the kinetic energy is equal in magnitude but of the opposite sign
