This practice book is __1__ for foreign engineers or students of engineering who have already mastered the elements of English, and who now want to use their knowledge of the language to read books on their own __2__. Readers should understand, however, that the purpose of the book is to teach language, not to teach engineering.
The language in which scientific and technical __3__ are expressed is certainly not a different language from that of everyday life, but all the same it presents the foreign students with a number of __4__ problems. The most obvious and most widely recognized of these problems is the __5__. Much more difficult are the semi-scientific or semi-technical words, which have a whole range of meanings and are __6__ used idiomatically. One of the aims of this practical book is to __7__ as many of these words as possible, and as often as possible: words such as work and paint and load and feed and force. Words like these look __8__, but they can cause a lot of trouble to the students.
But more than anything else, I have tried to describe the technical statement: that is , the __9__sentence rather than the individual word. Many of the structure __10__ in the books are essential to the expression of technical facts and ideas- at least for the present.
A intended
B dangerously
C facts
D completed
E vocabulary
F trivial
G present
H originated
I harmless
J subjects
K object
L special
M discarded
N frequently
O illustrated
