We love them，admire them，hate them，rebel against them，and ideally end up with a great friend where a parent used to be. Making that transition can be challenging，though. Here are some tips to help you approach your father on a man-to-man level.First of all，you don't have to get too emotional.If you're uncomfortable with the idea of baring your emotions，chances are pretty good that your dad feels the same way. You simply need to take the right approach，one that allows you to talk with your father and learn about him，but without making everything feel like a TV drama.Hobbies are a good place to start. If your dad taught you any of the pastimes that you currently enjoy，dive right back into them and show him what you've learned. Your hobby will serve as a good start point to help you develop a healthy friendship. Don't immediately jump into time intensive activities such as camping or fishing trips. Try to set up a regular time to just hang out. Let's say you don't have any hobbies in common with your father. Many guys are in this position. This is where beer comes in. Just meet your dad at a bar to put one or two back，or if you don't drink，get a casual dinner somewhere.Don't act like a kid. Remember that if you want your dad to treat you like the adult you are，you've got to show him that you've grown up. Be willing to talk about things such as money，sex and other taboo subjects that you regularly discuss with your friends. Your dad can take it. He's been doing this whole “life” thing longer than you have. Just be frank and honest.To build a relationship with your father as an adult，you need to show him respect and invest some time. It's not the easiest thing in the world，but it's important. There are thousands of guys out there who'd love to be able to talk to their fathers; make them jealous. Take the first step.21．What should you do，if both you and your farther are not good at baring emotions?A．Talk about your common hobbies. B．Make everything felt like a TV drama.C．Watch TV together with your father. D．Put up a TV drama for your father.22．What does the author mea n by saying the underlined sentence?A．Many guys are sitting in the wrong position. B．Many guys don't share any common hobbies with their fathers. C．Many guys have the right thought D．Many guys have no hobby.23．What does this passage mainly talk about?A．The problems between father and son. B．How to approach your father freely as an adult man.C．How to act as an adult before your father. D．Tips for men about how to cheer their father up. 24．For whom is this passage written?A．Fathers. B．Adult sons. C．Mothers. D．Physiologists.BI have been consistently opposed to feeding a baby regularly. As a doctor，mother and scientist in child development I believe there is nothing to recommend it，from the baby's point of view.Mothers，doctors and nurses alike have no idea of where a baby's blood sugar level lies. All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state，the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.It is not just unkind but also dangerous to say a four hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night. I've never heard anything so ridiculous. Baby feeding shouldn't follow a timetable set by the mum. What is important is feeding a baby in the best way，though it may cause some inconvenience in the first few weeks.Well，at last we have copper-bottomed research that supports demand feeding and points out the weaknessesof strictly timed feeding. The research finds out that babies who are fed on demand do better at school at age 5,7,11 and 14，than babies fed according to the clock. By the age of 8，their IQ (智商) scores are four to five percent higher than babies fed by a rigid timetable. This research comes from Oxford and Essex University using a sample (样本) of 10,419 children born in the early 1990s，taking account of parental education，family income，a child's sex and age，the mother's health and feeding style. These results don't surprise me. Feeding according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels.I hope this research will put an end to advocating strictly timed baby feeding practices.25．What does the author think about Dr King?A．He is strict. B．He is unkind. C．He has the wrong idea. D．He sets a timetable for mothers. 26．The word copper-bottomed in Paragraph 4 is closest in meaning to ________.A．basic B．reliable C．surprising D．interesting27．What does the research tell us about feeding a baby on demand?A．The baby will sleep well. B．The baby will have its brain harmed.C．The baby will have a low blood sugar level. D．The baby will grow to be wiser by th e age of 8. 28．The author supports feeding the baby ________.A．in the night B．every four hours C．whenever it wants food D．according to its blood sugar levelCDo you love the holidays，but hate the pounds that follow? You are not alone. Holidays are times for feasting and celebrating. Many people are worried about their weight. With proper planning，though，it is possible to keep normal weight during the holidays. Whether it is celebrating at the office party or sitting down for the traditional family dinner，regard eating as a time for tasting a variety of the foods. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy.Here are some tips for preventing weight gain and maintaining physical fitness：Don't skip meals. Before you leave home，have a small，low-fat meal or snack. This may help to avoid getting too excited before delicious foods.Control portions. Use a small plate (about 10 inches) and put aside the large ones that may encourage you to “load up.” You should be most comfortable eating an amount of food about the size of your fist. Once you have your “tasting” serving，move away from the buffet. Doing so will make it less tempting to be eating constantly as your appetite is inspired by the sight of food.Begin with soup and fruit or vegetables. Fill up beforehand on water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you feel full.Stick to physical activity. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories.Avoid high-fat foods. Dishes that look oily or creamy may have a large amount of fat. Choose lean meats .Fill your plate with salad and green vegetables. Use lemon juice instead of dressing or butter.29．Which of the following is NOT true according to the passage?A．You had better turn your attention away from delicious foods.B．Drinking some water of soup before eating helps you eat less.C．Holidays are happy days with pleasure but they may bring weight problems.D．Physical exercise can reduce the chance of putting on weight.30．Which of the following CANNOT help lose weight according to the passage?A．Lean meats. B．Dressing or butter. C．Raw fruit or vegetables. D．Physical exercise.31．Many people can't control their weight after the holidays mainly because they ________.A．can't help being tempted to ea t constantly B．take part in too many partiesC．enjoy delicious foods D．can't help turning away from the foods32．If the passage appears in the newspaper，you think it should belong to ________ Column.A．Holidays and Festivals B．Health and Fitness C．Fashion and Frontier D．Student Times ClubDEarly in the autumn of 1674，Henry Oldenburg，secretary of the Royal Society in London，received an extraordinary letter. Sent by Antoni van Leeuwenhoek，a draper from Delft in the Netherlands，it contained an unlikely-sounding claim.Using a microscope of his own invention，van Leeuwenhoek had seen tiny creatures，invisible to the naked eye，living in lake water. Some of these “animalcules (微生物) ” were so small，he later estimated that 30 million of them would still be smaller than a grain of sand.Royal Society fellows couldn't believe it. Even with his most powerful instruments，the celebrated English microscopist Robert Hooke had never observed anything like the little creatures.In fact，the Dutchman had developed far superior lenses to Hooke's，and had discovered bacteria and protozoans (原生动物)．By producing even smaller and more curved lenses—using a technique that he kept secret—van Leeuwenhoek was able to magnify objects up to 500 times. As well as discovering micro-organisms，he was the first to see red blood cells.In 1677，van Leeuwenhoek sent the Society further animalcule observations. Hooke eventually improved his own microscopes to the point where he，too，could see the tiny creatures. Three years later van Leeuwenhoek was made a fellow.It was not until 1890，more than 160 years after van Leeuwenhoek's death，that bacteria were linked with diseases. “Reading van Leeuwenhoek's letters，you very much get the impression of somebody dazzled by what he was finding，”says Lesley R obertson，leader of the archives at Delft University's school of microbiology. “He thought he'd found a whole new world—but he certainly never picked up on the connection with illness.”33．What did Antoni van Leeuwenhoek see with his own microscope?A．A letter. B．Bacteria and protozoans. C．Small animals in the water. D．The element of water. 34．From the passage we can see ________.A．van Leeuwenhoek knew the tiny creatures in the water had something to do with natureB．van Leeuwenhoek was the first to discover bacteriaC．van Leeuwenhoek was the first to use the microscopeD．van Leeuwenhoek was the first one to know how to observe bacteria and protozoans35．What does the underlined word “magnify” in the fourth paragraph mean?A．To clear away. B．To improve. C．To collect. D．To make large.36．From the last paragraph we can see，when Antoni van Leeuwenhoek saw the tiny creatures，invisible to the naked eye，living in lake water，________.A．he was overexcited B．he knew he followed someone else's discoveryC．he was a bit disappointed D．his discovery was to lead a connection between bacteria and illnesses答案1-20ACDDC DAACB DBDAB DACBC 21-36 ABBB CBDC ABAB BCDA。
