(Question)
Ask any student which subject he or she hates most. 9 out of 10 students will answer "math". No matter which country you visit, no matter which grade you are in, you may not learn art, geography, chemistry or Chinese, but you always learn math. Why is this so? How come so many students hate math, and yet cannot avoid learning it in school? Jenny Sanders, a high school student in California, asks, "What good do we get from learning math? We can use computers to compute numbers, and we can use computers to store information. I think learning math at school is a waste of time." However, there is much more to math than just learning to add and subtract numbers. In fact, math is not so much about calculation as it is about learning to think logically and solving problems. Of course, Jenny was right that we can use computers to do calculations, but how would we even know how to use the computer if we can't think logically? In short, computers are only tools when solving problems. For example, imagine you are a cook and must serve dinner to 100 guests. How should you divide your resources so that you can get the job done most efficiently ? In situations like this, the ability to think logically will get you to a reasonable answer and solve your problem. Which of the following is TURE according to the passage? A) 90%of the students hate learning math. B) Students can learn math well with computers. C) Math can do calculations and store information. D) Math helps students learn all the other subjects well.

To save yourself from embarrassment , it's good to read a few books or research online about the culture and customs of the country you plan to visit. Clothing: Wearing shorts in public is generally not acceptable in most parts of the world, including some European countries. Greetings: Handshake is a usually accepted form of greeting, although in some countries, like Japan, a traditional bow is preferred. Be careful how you talk with someone; don't use first names unless you are invited to do something. Language/Gestures: learn some polite expressions (hello-goodbye-thank you) and relax. English is pretty common worldwide, especially in tourist areas and you can always use body language to get your message across. However, some Americans gestures have different meanings in other countries. For example, in Bulgaria, shaking your head usually means "yes"; shaking it "vertically" means " no". Food/Drink: you may find yourself looking down at a local delicious snake soup in china, sheep's eyes in Saudi Arabia... and wonder what to do; especially you are guests in someone's home. Be brave, take small bites, and pretend it tastes like something you like. Remember that some Buddhists don't eat beef, and Muslims don't eat pork. If you are eating with Muslims, never touch food with left hand (the left hand is for bathroom use). Conversations: if you know the history and culture of the country, you will be confident. The French are angry at the classic American question: "What do you do for a living?" and so on. Which of the following isn't right? A) You can't wear shorts in public in most parts of the world. B) You can use body language to communicate with people. C) You can use your left hand to touch food when you eat with Muslims. D) You can get along well with people you visit if you know their culture and customs well.
