The lecturer speaks for one or two hours, perhaps 21 the talk with slides, writing up important information on the blackboard, 22 reading material and giving out 23 . The new student sees the other students continuously writing on notebooks and 24 what to write. Very often the student leaves the lecture 25 notes which do not catch the main points and 26 become hard even for the 27 to understand. Most institutions provide courses which 28 new students to develop the skills they need to be 29 listeners and note-takers. 30 these are unavailable, there are many useful study-skills guides which 31 learners to practice these skills 32 . In all cases it is important to 33 the problem 34 actually starting your studies. It is important to 35 that most students have difficulty acquiring the language skills 36 in college study. One way of 37 these difficulties is to attend the language and study-skills classes which most institutions provide throughout the 38 year.

Last week I saw the release of the second part, and boy oh boy does it shows. But watching the film as a foreigner I felt I was missing out on something. Not knowing my Cao Cao's from my Zhou Yu's, I was not even sure whom I wanted to win. Certainly after the opeing scene, in which Cao Cao is seen watching a game of Cuju, an ancient Chinese variation of football, I knew who had my support. After all, any man who enjoys his football is someone after my own heart. But after Cao Cao resorted to some evilness strategies against his enemies in the south, I wasn't so sure he was the man I should be rooting for. And there is a lot more to Red Cliff 2 than just extravagant battle scenes. The film does not take itself too seriously. Conversations between leaders are littered with one-liners, many of which had the audience in laughter. There is even enough to keep fans of more romantic entertainment happy too. This includes a charming relationship between a southern spy(侦探)and an innocent northern soldier. The characters' interaction provides some genuinely heart-warming moments in the middle of the battle. Clocking in at around two hours, the film certainly does justice to the history story. When I walked out the cinema, I felt as drained as Cao Cao's soldiers must have 1,800 years ago. 41(By expressing ―boy oh boy‖ in the first paragraph, the author seems to show that _______. A(the film characters are like boys who are childish. B(the film provides amazing and surprising scenes for audience. C(the film is suitable for younger boys to watch.

B(When he saw Cao Cao was watching a game of Cuju, C(When he realized that Cao Cao took some bad measures to beat his enemies. D(When he saw the romantic love story of Cao Cao and a southern spy. 43(The following factors of the film are all mentioned in the passage except_______. A(high budget B(leading roles C(actors and actress D(conversations 44(From the passage we can infer that_______. A(the author is a football fan in a foreigne countriy. B(Cuju is the name of an ancient Chinese variation of football. C(the film Red Cliff 2 lasts about two hours. D(the author was very tired after about two hours’ battle. B The Museum of Childhood is spread over 4 floors, with the first floor acting like a balcony around the edge of the building, so you can look down over the ground floor central hall with the shop.

Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison, an ―Official Taste Tester‖ for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream—as well as for developing over 75 flavors. Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No—there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this ―cool‖ field. In a typical morning on the job. Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12?F. Harrison explains, ―You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup.‖ While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. ―Tasting begins with the eyes,‖ he explains. He checks to see if the ice cream is attractive and asks himself，―Does the product have the color expected from that flavor?‖ Next it’s time to taste! Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy – working at one cool job. 49(What is John Harrison’s job?

But, it is not as hard as it seems and the most important thing for any learner to achieve is confidence with the language.

To do this ,schools have developed General English courses which combine a range of different teaching methods. In class, teachers encourage students to work together so that they can practice new words and grammar. They always try and make this classwork interesting and fun. Many schools are equipped with language laboratories and libraries where students can work on their own with audio tapes, video and computers. And outside the classroom, the learning continues, where students are meeting together socially, visiting local attractions, or at home with a host family. Most schools offer General English courses which are either part time—usually 15 hours per week or full time, which can be as much as 40 hours. This type of course is available all year round. Students can normally start a General English courses every Monday , and can study for as long as they like. Other types of General English courses may last a minimum umber of days or weeks.
