The Nazis had acquired the technique and knowledge of making an atom bomb. They could develop an atom bomb. It could destroy the whole part of the world if they exploded it. This concern for the world made him write that letter.

II. Study the following sentences :

• Einstein became a gifted amateur violinist, maintaining this skill throughout his life.
• Letters survive in which they put their affection into words, mixing science with tenderness.

The parts in italics in the above sentences begin with – ing verbs, and are called participial phrases. Participial phrases say something more about the person or thing talked about or the idea expressed by the sentence as a whole. For example :
– Einstein became a gifted amateur violinist. He maintained this skill throughout his life.

Complete the sentences below by filling in the blanks with suitable participial clauses. The information that has to be used in the phrases is provided as a sentence in brackets.

WRITING NEWSPAPER REPORTS
Here are some notes which you could use to write a report.
21 August 2005 – original handwritten manuscript of Albert Einstein unearthed – by student Rowdy Boeynik in the University of the Netherlands – Boeynik researching papers – papers belonging to an old friend of Einstein – fingerprints of Einstein on these papers – 16- page document dated 1924 – Einstein’s work on this last theory – behaviour of atoms at low temperature – now known as the Bose – Einstein condensation – the manuscript to be kept at Leyden University where Einstein got the Nobel Prize.
Write a report which has four paragraphs, one each on :

• What was unearthed.
• Who unearthed it and when.
• What the document contained.
• Where it will be kept.

Your report could begin like this :
Student Unearths Einstein Manuscript
21 August 2005. An original handwritten Albert Einstein manuscript has been unearthed at a university in the Netherlands…

Answers
Student Unearths Einstein Manuscript
21 August 2005. An original handwritten Albert Einstein manuscript has been unearthed at a University in the Netherlands.

A student named Rowdy Boeynik was researching papers. These belonged to an old Mend of Einstein. He found the fingerprints of Einstein on these papers. This confirmed that these were of Einstein.

The document contains 16 pages and is dated 1924. It has Einstein’s work on his last theory. It was on the behaviour of atoms at low temperature. Now it is known as the Bose- Einstein Condensation.

The manuscript is to be kept at Leyden University where Einstein got the Nobel Prize.

DICTATION
Your teacher will dictate these paragraphs to you. Write down the paragraphs with correct punctuation marks.
In 1931 Charlie Chaplin invited Albert Einstein, who was visiting Hollywood, to a private screening of his new film, City Lights. As the two men drove into town together, passersby waved and cheered. Chaplin turned to his guest and explained : “The people are applauding you because none of them understands you and applauding me because everybody understands me.

One of Einstein’s colleagues asked him for his telephone number one day. Einstein reached for a telephone directory and looked it up. “You don’t remember your own number ?” the man asked, startled.

“No,” Einstein answered. “Why should I memorise something I can so easily get from a book ?” (In fact, Einstein claimed never to memorise anything which could be looked up in less than two minutes.)
