Often times, we use colors to describe how we're feeling. If you're feeling sad, you might be “blue”, ____ if you're feeling happy, you might be “yellow”. So, what's the color of your feeling for the new semester?   Happy       Are you happy about starting the new term? Perhaps you can't wait to go ____ to school, see your friends again, and meet your teachers. If so, then your color is orange or yellow. These colors stands for ____ (happy), joy and energy. You probably  have a positive and cheerful attitude about ____ (go) to class.   Worried       Or maybe you're a bit worried about the new term. If you're not excited about doing ____ (much) schoolwork or seeing your teachers again, then you are probably blue or gray. These colors stands for sadness.   Excited       A new term means that you have the chance to start over again. Are you excited to meet your new friends and learn about new things? If this describes ____ you feel, then you're definitely red or green. These colors are good luck and stands for excitement.       But instead of picking just one color, why not be lots of different colors combined? Purple is the color of being clever and creative --- ____ is a good thing for the start of a new term. And white stands for knowledge and balance.       No matter how you're feeling about the new term, and what color ____(match) your feeling, try to be a rainbow of colors. Be outgoing and fun [orange], hardworking and wise[purple],and energetic[yellow]. Live the new semester in full colors!
