1) I've been working on this problem for 3 months. 2) We have not received letters from her for several months. 3) Tomorrow father comes late. We'll tidy the apartment and we'll drink tea when he comes. 4) How long have you been waiting for me? 5) Yesterday, I met a friend whom I had not seen for a long time. 6) She's going to read a letter she has just received. 7) When did you see him last? 8) Do not talk to him, he is very busy, he is doing a very important job. 9) He was afraid that something would happen. 10) He has been watching TV since 6 o'clock. 11) What will you be doing tomorrow at 8:00? 12) I'll have done my homework by 6 o'clock tomorrow. 13) We have not had breakfast yet. 14) If I do not help him, he won't write the test well tomorrow. 15) - Have you ever been to Paris?- I'll go to Paris as soon as I solve this promlem.
It's great to be here. We'll name our new military airport after your most famous son, the great mathematician Muhammad al-Khwarizmi, who lived in the ninth century of the Christian era -- sorry, the Common Era.
We'll build Firebase Algorithm, a word derived from his last name. The book he wrote, Kitab Al-Jabr, christened the field of algebra. Whoops! We should have said Al-Jabr was its basis.
We'll add a lot more bases. Your social problems might multiply as we search for X, then Y, then Z, the unknown quantities, the solutions to our problem,
but we're grateful for your support, glad that al-Khwarizmi developed the “calculus of two errors.” It will help us differentiate terror from infinite justice -- make that “enduring freedom.”
We give thanks that al-Khwarizmi launched the decimal system, so we can keep easy body counts, flash results on television, and when the Great Game ends post the scores in Arabic numerals: Muslims, zero. Christians, zero. Civilization, zero. вот кароч
