6. Translate the sentences from exercise 5 above into Czech. 7. Translate into Czech (taking into account that the principles of the sequence of tenses used in English do not apply in Czech).One of our teachers remarked that many people were not aware of the fact that the food industry using the achievements of chemistry that had been reached, in particular, in the preservation of food along with the manufacture of synthetic additives, had made significant progress as early as in the latter part of the 19th century, not speaking of the first half of the 20th century. At the same time, the progress in physics was very fast. Let us mention that when Thomson discovered the electron, he proved that there were particles which were smaller than the smallest atom known. Roentgen found that the X-rays would pass through solid substances. In 1932 Chadwick reported that he had discovered the neutron. The Curies found that pitchblende was several times more active than uranium oxide. Becquerel noticed that salts of uranium possessed the property of emitting rays.

PASSIVE VOICE

The passive voice is widely used in scientific texts due to the fact that what goes first in the English sentence is considered to be the most important. Scientific texts tend to use passive voice structures frequently to make sentences sound more objective and avoid using personal pronouns. In Czech we use passive structures less commonly. Structure:

subject (which is not the agent)verb to be in appropriatetense form3rd form of the content verb

The thesisis/was/has been/will be etc.written

The thesisis/was etc. beingwritten

When the continuous form is needed, we insert being (-ing form of the verb to be) between the verb to be and the content verb.I wrote the thesis. The thesis was written.

I have written the thesis. The thesis has been written.I will write the thesis. The thesis will be written.Im writing the thesis. The thesis is being written.Structure of the passive voice in combination with the infinitive (which is not used

in Czech): subject + passive + infinitiveThe verbs believe, expect, know, report, say, think, suppose, understand are often used in the present simple passive followed by an infinitive.He is said to live here (It is said that he lives here. the subject of the second sentence replaces it from the first sentence and the rest is connected in the form of infinitive).He is said to have lived here. (It is said that he lived here.)

The new library is supposed to open next week.

The economy is expected to grow by 2% this year.

The simple infinitive refers to the same time as that of the preceding verb:

This compound is expected not to react. (Notice: The negative particle not precedes the particle to.)The perfect infinitive refers to a time before that of the preceding verb:

This decade is known to have been a decade of many discoveries.Exercises:

RELATIVE CLAUSES

1/ defining relative clauses

2/ non-defining relative clauses

1/ Defining relative clauses are an essential part of the message of the sentence (they clearly identify which person or thing we are talking about) and therefore cannot be omitted and are not separated with commas. The doctor who treated me told me not to worry.2/ Non-defining relative clauses bring additional but non-essential information (facts, opinions), so they are marked with commas and could be easily left out without the main sentence losing its meaning. Alexander Fleming, who died in 1955, was a Scottish biologist, pharmacologist and botanist.Relative pronouns: who for people, which for things and that for both categories. However who is preferred for people and in defining clauses that is usually used for objects. We can drop the relative pronoun if it defines the object of the clause (this applies to defining clauses only). My friend (who) I visited on Saturday has just called me. The doctor I spoke to told me not to worry.In non-defining relative clauses that is not used, so we only use who for people and which for objects and we do not leave the relative pronoun out of the sentence. The doctor who treated me was very professional.Possessive whose is used for people and for things..the student whose diploma thesis

the laboratory whose windows.

Relative adverbs: where, when, why describe place, time or reason. Instead of a relative adverb, we can use a preposition + which.

That was a year when I graduated. / That was a year in which I graduated.

Notice:

Which may also be used in non-defining clauses to refer to the whole of the main sentence (this corresponds with the Czech relative pronoun co). He didnt call me, which was disappointing.Notice:

What cannot be used as a relative pronoun. It is a pronoun that introduces object clauses.

He told me what he did. (what = the thing that, everything that, all that) - object clause

He told me everything (that) he did. - relative clause

Exercises:

1. a/ Explain the following words using relative pronouns or adverbs. ex.: knife a knife is a tool which..... or: a teacher is a person who... dean, inorganic chemistry, optional subject, chemist, library, oxygen, lecture hall thermometer, researcher b/ In pairs, think of any word and describe it to your friend without saying what it is. Your friend will try to guess what your word is. Change roles. Use relative clauses (It is a thing that... etc).

2. Join the following pairs of sentences using relative pronouns.

Make the underline sentence the relative clause.a/ The teacher is very strict. He teaches chemistry.

b/ Peter speaks German. His wife is from Austria.

c/ The new dean is very popular. He gets on well with students.d/ We spoke to a teacher. He gave us some instructions.

e/ We need to work with a poisonous chemical. It is stored in a special receptacle. f/ It was 2005. I met him for the first time.

g/ We work in a laboratory. Its cool.

h/ We work in a laboratory. Its cool.3. Decide which relative pronoun is correct and where it could be omitted.a/ The man who/which called is our schoolmate.

b/ Have you found the books who/that I lent you?

c/ It is the best news that/which came today.

d/ It is the best news that/which I have heard so far.

e/ I sent her all the notes that/what I had.

f/ I sent her that/what I had.

g/ I went to a place where/which/that I could work undisturbed .

h/ This is the student who/that/whose work has won the first place in our competition.

i/ I work for a firm which/that sells chemicals.

j/ I couldnt complete my research, who/that/which was a pity.

ENGLISH SPECIFIC INFINITIVE STRUCTURES

Some infinitive structures that are used in scientific English do not have equivalent Czech counterparts, and therefore need to be translated by using other linguistic tools.

1. To express result

e.g. Hydrogen burns in air to give water vapour.

Hydrogen is used in the hydrogenation of liquid fats to form solid fats.

Translation: a (tvo), za (tvorby, vzniku)Only a few verbs are used in this form (namely give, form, produce and yield) and they usually follow a verb describing a chemical process or reaction, such as burn, react, combine, unite, dissolve, decompose, boil, polymerize, hydrogenate etc.2. To express purpose

e.g. a) The compound must be heated (in order / so as) to decompose.In this sentence the two verbs heated and decompose are linked to the same subject compound, so we can simply use the infinitive to express the purpose of the action.)

b) The reaction mixture must be heated for the reaction to occur.

In this sentence we have two subjects mixture and reaction. Therefore we need to use for to introduce the second subject.Translation: aby3. To specify a noun

e.g.: the condition to be controlledTranslation: podmnka, kter m bt/ bude sledovna4. To provide information about knowledge or findings

verb + object + infinitive

e.g.: She found the intensity to be greater. (= She found that the intensity was greater.)

We know Roentgen to have discovered the X-rays. (= We know that Roentgen discovered the X rays.)

Translation: Zjistila, e je

Vme, e. objevil

The same information can be in the passive:

subject + passive verb + infinitive

e.g.: The intensity was found to be greater. Roentgen is known to have discovered the X-rays. Translation: Zjistilo se, e O Roentgenovi je znmo, e ..

Exercises:

1.Translate

1. We know carbon to occur in two crystalline forms that differ in their properties.

2. To prepare synthetic salt place a piece of sodium in a flask with chlorine.

3. The amount of water to be added is dependent on the pressure of the distillation.

4. The solution of carbon dioxide in water is found to colour blue litmus red, showing it to be

a weak acid.

5. The reaction mixture must be brought to a sufficiently high temperature for the reaction to

occur.

6. The material to be weighed is transported to and from balance room in a desiccator.

7. We found the value to depend on many various factors.

8. The alloy was found to be composed of silver and gold.
