W: Well, can we summarize the problem from our point of view？ First of all, the campaign was late. It missed two important trade fairs. The ads also did not appear into key magazines. As a result, the campaign failed. Do you accept that summary of what happened？
M: Well, the delay wasn't entirely our fault. You did in fact make late changes to the specifications of the advertisements.
W: Hmm, actually, you were late with the initial proposals, so you had very little time. And in fact, we only asked for small changes.
M: Well, whatever. Can we repeat our offer to run the campaign for four extra weeks？
W: That's not really the point. The campaign missed two key trade fairs. Because of this, we're asking you either to repeat the campaign next year for free, or we only pay 50% of the fee for this year.
M; Could we suggest a 20% reduction to the fee together with the four-week sustention to the campaign？
W: We are not happy. We lost business.
M: I think we both made mistakes. The responsibility is on both sides.
W: Ok, let's suggest a new solution. How about a 40% cut in fee, or a free repeat campaign？
M: Well, let's take a break. We're not getting very far. Perhaps we should think about this.
Questions 22 to 25 are based on the conversation you have just heard.
22. What do we learn about the man's company？
23. Why was the campaign delayed according to the man？
24. What did the woman propose as a solution to the problem？
25. What does the man suggest they do at the end of the conversation？
(25)
A．It publishes magazines.
B．It is engaged in product design.
C．It sponsors trade fairs.
D．It runs sales promotion campaigns.
1 Watching movies or television shows as a way to “passively” learn a language sounds like a language learner’s dream. That is. 2 Passive language acquisition is one of those myths that preys on the lazy “couch beast” inside each of us that tries to get something without putting forth any effort. Learning a language takes work. You just can’t become fluent by passively listening to a language. 3 Movies and TV shows can help, but not if you plant yourself in front of a screen for eight hours a day. You’re no more likely to learn a language doing this than you are to become a pilot by watching aeroplanes. You just need the right approach and mindset. Here are some suggestions. Don’t just watch the movie. Study it. Viewing a movie for entertainment means you aren’t focused on learning the language. Treat the movie like you would a textbook, and study the material. Break things up into consumable, repeatable segments. A two hour movie is too much language to absorb at once. Break it up into segments of 10 minutes or less, and review them multiple times until you have really learned something of substance. 4 Engage with the material. A movie is an open book on body language, accents, inflection, pronunciation and many other areas of language learning. Don’t just sit on your hands! Get involved in the story, act out parts, repeat lines and body movements and make the language come alive! 5 As with movies and television shows, listening to music is often seen as a magic path to learning a language. The problem is that songs are written poetically so they aren't usually a good source for everyday grammar and vocabulary. 6 Listening to songs does have its place in a language learning mission — as long as you have the right approach. Instead of repeating myself, I’ll just recommend that you do the same as you would for movies or television shows: study the music (don’t listen passively), repeat segments (to really understand the material) and engage with the song (don’t just listen — sing!). 7 One additional fix is to recognise that song lyrics often take creative license with a language, so while they are helpful to your studies, keep in mind that it is the equivalent to studying poetry. According to this passage, why does the writer of this passage suggest that watching movies or television may be like a language learner’s dream？
A、Because watching movies or television may not involve any effort.
B、Because watching movies or television may take too much time.
C、Because watching movies or television may not contribute to language learning.
D、Because watching movies or television may have too much to enjoy.
.______ from 2.5 billion in 1950 to over 7 billion.Food became a big problem as we were not able to feed everyone.Now the world’s population is 2.______ to continue growing and may 3.______ 11 billion by 2100.So in a world 4.______ nearly 1 billion people already do not have enough food, can we really feed another 6 billion？ Population growth is not the only reason for food shortages.Our diet is also to 5.______ for it.Nowadays, with increasing numbers of people living in cities, we tend to eat more meat.To produce meat we have to use a lot more land and water to grow the food for the animals.And we also need more energy to process the meat.As a result, we are using more land and resources to actually produce less food.We could feed the growing population easily if everyone became a 6.______.But who would make this change？ Would you give up meat to feed others？ Innovative solutions to this problem are being used and researched around the world.One idea being tried is 7.______ farming, which is to build farms in very tall buildings in the centre of cities.Such farms require less space.They also reduce the distance the food needs to travel to 8.______ most people.Another 9.______ idea is the “seeds in space” project organised by the Chinese Academy of Sciences.
Actually, our senses and memories are more connected than we think.Researchers have discovered 10.______typically, a strong connection between smells, emotions and life experiences is 11.______before age 5.This is 12.______ true for smells that we don’t smell every day.But even in 13.______, links are made between smells and memories.You might make a connection between a 14.______ and a friend or lover, or the smell of a certain food may take you back to the first time you ate it.The reason time 15.______ to go more quickly as we get older is that we repeat the same 16.______ and experience the same events over and over.Doing things for the first time usually leaves a strong memory.Remember your first day of school or a new job？ But as we repeat those 17.______, strong memories aren’t created, and time goes quickly.You heard a song on your way to campus, and you found it hard to get rid of it for the rest of the day.Songs that 18.______ in your head all day are known as “earworms”.It was found in one study that nearly 92% of people have such an experience once a week or more.Earworms are started by many different kinds of things, such as going back to the same place 19.______ you first heard a song.People also often listen to sad music when they are in a sad 20.______, and stressful situations often remind them of that song.
Knowing what you value most is only the first step.Sometimes in reality, we cannot find a job that satisfies all our needs or is perfect in every way.If we have too much of one thing and not enough of another, we are unlikely to be satisfied.Finding a balance between the factors and deciding what to give up is even more important.

In order to solve a computational problem, its solution must be specified in terms of asequence of computational steps, each of which may be performed by a human or a digital computer. If you want to solve the computational problem with a computer, you shouldlearn how to program. The task of developing programs for the solution of computationalproblems is referred to as programming. Computer programming is the process of planningand creating a sequence of steps for a computer to follow. In general, this process will helpus resolve a problem, which is either too tedious or difficult to work out otherwise. Soprogramming is breaking a task down into small steps.
Programming is sometimes contrasted with coding. Coding generally refers to thewriting of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of aprogram is sometimes referred to as code, and lines of program text are referred to as lines ofcode, especially in the case of machine-language programs. The term coder is used todescribe a person engaged exclusively in implementing program specifications prepared byothers. What ' s actually involved in programming - the actual process of writing programs？ Here' s a quick overview of the process:
• Write a program.
• Compile the program.
• Run the program.
• Debug the program.
• Repeat the whole process until the program is finished.
