“It’s not enough to get good grades in school,” she said in the speech. “It is better to travel 10,000 miles than to read 10,000 books. The experiences in other countries help make our life successful. By learning each other’s languages and b y showing such curiosity (好奇) and respect (尊重) for each other’s cultures, you are building bridges of understanding and bonds of friendship,” she said. The US is the top destination (目的地) for Chinese students. More than 200,000 Chinese students are now studying in the US. In 2009, US President Barack Obama announced (宣布) his goal of sending 100,000 students to China. Since then, more than 68,000 US students have come to China. What’s more, many kids in the US are now studying Chinese. “Learning Chinese is a cool thing in school.

Note-taking is a skill that can help you do well in all your schoolwork. It can make you confident when you are studying. But unluckily, most students don't know how to take notes. Here are some suggestions:
Write down key facts. If your teacher writes notes on the blackboard, that's great. You can copy them or write down the most important facts of all in class. Different teachers do things differently. For example, some teachers may focus on (关注) lots of dates and facts in class, but they only write the important ones on the blackboard. Other teachers may not write anything down, but they may repeat them. Don't try to write down every word in class, or you might miss some important points. Some students really learn better with the help of these notes.
Ask. Don't be afraid to ask your teacher to repeat what you're missed. If your teacher speaks too fast and you can't follow what he is saying, you can ask him after class.
Compare. Comparing (对比) your notes with your classmates' can be good for your learning. It can also help you and your classmates correct some mistakes.
Organize. Note-taking also needs organization. Keep notes for each subject in one place, so that you can find everything easily when a test comes.
Good note-taking takes time. If you decide to recopy your notes every evening, you'll surely have less time to watch TV. But you'll save time in the coming test comes.
▲ Note-taking can help you (66) _________________ all your schoolwork.
▲ Different te achers do things differently. Some of them like to tell their students many dates and facts but they only write the important ones on the blackboard; others may repeat them instead of (67) ________________.
▲If you miss some important points or can't foll ow your teacher in class, don't (68) ____________________ to ask him or just compare your notes with(69) ____________________.
▲ This passage mainly tells students(70) ___________________.
