1 W ORDBUILDING SUFFIXES AIMS: 1. TO LEARN THE MOST IMPORTANT SUFFIXES USED IN ENGLSIH 2. TO LEARN SOME DERIVED WORDS TYPICALLY USED IN CHEMISTRY TEXTS

3 T HINK : 1. What’s the purpose of the placement test? 2. Where are you when compared to your colleagues? 3. What are the things that you can do in order to catch up with them?

4 1. It’s diagnostic. The results are supposed to give YOU and me some idea of your knowledge. 2. This course is designed for INTERMEDIATE students – those are the ones with the score of 40-65. 3. Dos and don’ts: Start learning from the day one Come and see me if you have any problems Use Power Book to get some additional practice DON’T SKIP English lessons DON’T THINK that you can learn everything in a few days

5 W ORDBUILDING = MAKING NEW WORDS FROM THE SMALL ONES We can use suffixes and prefixes to make new words. Suffixes are used at the end of the word. slow – slowly important – importance pure – purify beauty – beautiful Prefixes are used at the beginning of the word. happy – unhappy appear – disappear atomic – polyatomic

6 C OMPLETE THE SENTENCES. M AKE NOUNS FROM THE ADJECTIVES IN BRACKETS. 1. They weren’t prepared for the ___________(dark) of the polar winter. 2. They didn’t achieve their ___________ (ambitious). 3. The journey was a _______________ (disastrous). 4. They suffered from _____________ (exhausted). 5. They knew ____________ (dead) was near. 6. They are remembered for their _____________ (brave) in the face of great difficulty.

7 T HE EXAMPLES FROM P.9 ARE SIMILAR TO THE EXAMPLES YOU ’ LL GET IN THE TEST Adjectives → Nouns dark (adj.) → dark ness ambitious (adj.) → ambit ion disastrous ( adj.) → disaster exhausted (adj.) → exhaustion dead (adj.) → death brave (adj.) → bravery difficult (adj.) → difficulty

8 Verb → Noun explore → exploration organise → organisation prepare → preparation succeed → success

9 Noun → Adjective pole → polar patience → patient ambition → ambitious courage → courageous success → successful

10 G ENERAL E NGLISH 1. Money can’t bring you _____________ (happy). 2. He is a very ___________ (ambition) young man. 3. It was a ____________ (disaster) decision. 4. His _________ (dead) came as a shock. 5. They will be remembered for their great _______ (brave). 6. Their experiment was a complete ________ (succeed). 7. What’s more important – _________________ (educate) or experience? 8. Their __________ (explore) led them into the deserts of central Asia. 9. You’ll have to be _________ (patience) with her. She’s a slow learner. 10. ________________ (pole) ice is very important for the world’s climate.

11 U SE THE WORD IN BRACKETS TO MAKE A NEW WORD AND COMPLETE THE SENTENCE IN THE BEST WAY. 1. Money can’t bring you happiness (happy). 2. He is a very ambitious (ambition) young man. 3. It was a disastrous (disaster) decision. 4. His death (dead) came as a shock. 5. They will be remembered for their great bravery (brave). 6. What’s more important – education (educate) or experience? 7. Their experiment was a complete success (succeed). 8. Their explorations (explore) led them into the deserts of central Asia. 9. You’ll have to be patient (patience)with her. She’s a slow learner. 10. Polar (pole) ice is very important for the world’s climate.

12 Chemistry Chemistry was my favourite subject at school. Chem ical = hemikalija Chem ist = hemicar Chem ical = hemijski Biology Biology is a very interesting science. Biolog ist = biolog Biolog ical = bioloski

13  Don’t touch that. It’s a very dangerous _______(chemistry).  Do you know enough about your ____________ (biology) clock?  A chemical __________ (react) transforms one or more substances into different substances.  It’s a ___________ (poison) gas.  Water is ___________(colour).  Is _______________ (soluble) influenced by temperature?  You should destil it under normal _______________ (press).  The______________ (molecule) mass (abbreviated M) of a substance is the mass of one molecule of that substance.  The chemistry of carbon is called _____________ (organ) chemistry.  For each compound, an ____________ (oxygen) number for iron is given.

14  Don’t touch that. It’s a very dangerous chemical (chemistry).  Do you know enough about your biological (biology) clock?  A chemical reaction (react) transforms one or more substances into different substances.  It’s a poisonous (poison) gas.  Water is colourless (colour).  Is solubility (soluble) influenced by temperature?  You should destil it under normal pressure (press).  The molecular (molecule) mass (abbreviated M) of a substance is the mass of one molecule of that substance.  The chemistry of carbon is called organic (organ) chemistry.  For each compound, an oxidation (oxygen) number for iron is given.

15 F ILL IN THE GAPS IN THE SENTENCES BELOW USING WORDS BASED ON THE ROOT IN BRACKETS. The chart shows the relative ________________ (abundant) of some of the elements in the lithosphere. The _________________ (rare) of these minerals in the crust makes them very expensive. They generally have the similar properties of ________________ (hard), high melting and boiling points, and low electrical _________________ (conduct).

17 Graphite is also used as a _________________ (lubricate), and as an electrode in electrolysis - for example, in the manufacture of aluminium. Ammonia is used to make the __________________ (fertile) that farmers spread on the soil to feed their crops. The source of carbon for this __________________ (reduce) is coke, obtained by heating coal in the absence of oxygen. It is possible to tell if a solution is acidic or alkaline by using an ___________ (indicate).

19 able – ability absent – absence absorb – absorbent – absorption acid – acidify active – activation add – additive analyse – analysis – analytical anhydride – anhydrous atmosphere – atmospheric atom – atomic attract – attraction – attractive calculate – calculation carbon – carbonation – carbonic character – characteristic class – classify collide – collision colour – colourless concentrate – concentration conduct – conductivity connect – connection

20 corrode – corrosion – corrosive detect – detection – detectable deep – depth evaporate – evaporation experiment – experimental flame – flammable gas – gaseous high – height ion – ionic – ionize – ionization line – linear long – length magnet – magnetic – magnetism move – movement nature – natural odour – odourless pure –purity - purify – purification react – reaction – reactive strong – strength tend – tendency
