Нужно выписать предложения в Present Continuous и в Past Perfect
Chester was feeling more tired than usual after a hard day at the office. He hadjoined the company only two years before. He had come straight from universitythen, but now he was a junior manager in one of the biggest companies inSingapore. It was an important position to have and meant lots of extra work.He could understand the jealousy that some of the other workers might feelagainst the 'new boy', as they still called him. He had risen quickly in the company.Many of them, however, had been there for years doing the same jobs. Hecould understand how bad feeling towards him might lie hidden behind theirsmiles.But it didn't make life any easier.He needed people whose advice he could trust when he had to make difficultdecisions. He had to be sure that the bad feelings of the other workers didn't get inthe way of the important business decisions he had to make. He knew he wouldnever become a manager unless he could be sure of people.Then there was Dorothy.Chester was fairly sure of his own good looks. He was dark and slim anddressed smartly, but with an eye to fashion. He was a confident speaker andbelieved himself to be a sociable and effective junior manager.But when it came to Dorothy his judgement disappeared. Dorothy was abright girl who had just joined the company, straight from university. He wasattracted at once by her intelligent eyes, her shy, pretty face and her soft, roundfigure.Ah, Dorothy!Take today, for example. He had been given some new figures to check and hehad asked Dorothy to read some of the details to him while he took notes. It wasnot until she had left that he realised that he had not written notes at all. Instead hehad written Dorothy's name several times. He was too embarrassed to ask Dorothyfor the details again, so he had to look them up in the office of old Mr Shaw.Mr Shaw was known for always being^in a bad mood and he was no differentthis time. He didn't like having to stay late to check figures for some juniormanager. He didn't like it at all.Chester hated it when he made mistakes. It didn't look good. But it didn't happenoften.He decided he would walk home instead of taking the train. It was late in theevening but he felt he needed the walk to clear his thoughts after a busy day.Anyway, it would be a little punishment for being so stupid earlier on. He decidedthat he would eat at the shopping centre near his home. He liked the Chinese foodthere.As he walked towards his favourite Chinese restaurant, he saw that the lightswere still on in an old antique shop. He had often thought of looking into this shopbecause he liked shops that sold old things. He stopped and looked. There wereboxes full of old books piled outside the shop. On the shop window was a notice. Itread: Sorry, shop closed today. Open again tomorrow.He bent down to look at the books. He saw all the usual old books: school books,cookery books and other books with dirty, yellowing pages that were of no value tohim. There was one small, old book, however, that he noticed at once. It lookedmuch older than the rest of the books. He picked it up.'Take it!' said a voice behind him.
