The intelligence of dogs There are three types of dog intelligence: instinctive intelligence, adaptive intelligence, and working and obedience intelligence. The first is a dog's ability to perform the tasks people (1) had bred / were breeding it to do. For example, in Britain, people (2) used to / would enjoy a sport called 'bull baiting' in which dogs (3) attacked / were attacking an angry bull. Bulldogs were bred to have strong jaws so that they would be good at this cruel sport. Thankfully, the government (4) banned / had banned the sport in 1835. Adaptive intelligence refers to a dog's problem-solving abilities such as how to reach something it wants. Working and obedience intelligence refers to a dog's ability to learn from humans. Psychology professor and dog lover Stanley Coren (5) had been wondering / was wondering for some time how to calculate this. While he (6) researched / was researching dog behaviour, he realised he could measure how long it took different breeds to learn and obey a command. In 1994, he (7) had published / published his findings in a book, The Intelligence of Dogs. According to Coren and the obedience trainers he (8) had consulted / was consulting, of the 110 breeds tested the 'smartest' dog was the Border Collie, and one of the 'dumbest' was the (now) loveable Bulldog!
The holidays have arrived again! It (1) did not seem like a year since the last summer break, but in a (2) few days we’ll finish school 3) ответ for (?) six weeks! I’m not sure what I’m going to do this year. (4) Last year I did a summer job. I was helping out my dad in his office when he (5) asked me if I wanted to be ответpaid for it! It was only two mornings a week, but it gave me some money (7) to spend.
How about you? (8) Have you decided (9) to go away anywhere this summer? I’ve been invited (10) by some friends to go on a sailing holiday and I think I will go. I love sailing. One reason I am writing to you is to (11) ask if you would like to come and stay for a weekend. (12) If you come at the end of August, we (13) will
be able to go to the music festival in (14) the park. I’m (15) not
sure if Lily Allen will be there this year, though. Write and tell (16) me soon because (17) there aren’t many tickets left.
В 3 не вижу лучшего варианта: через несколько дней школа закончится на 6 недель (for 6 weeks)
