任务型阅读：阅读下面的短文并从方框中的 A-F 中为每段文字选出最佳标题，在答题卡上将对应的选项涂黑。其中有一项选择是多余的。（共5小题，每小题1分，满分5分）
小题1: Whatever you have learnt or read in a day, practice in front of the mirror. For a start, you can read something from newspapers, English magazines, and books. Take a passage and read it aloud. After you think your accent has improved, try reciting a poem in front of the mirror. This will increase your confidence as well. 小题2: Talk to your family members and friends in English. You can also organize debates and speeches on a low level, where everyone in your family or friend circle speaks on one topic for a few minutes. It will help you get over the fear of making mistakes, as you will be with your friends and family—your comfort zone. 小题3: Listen to people who you think are good English speakers. It will help you catch the skill better. You can also watch their videos, listen to them online, or even in person. It can be anyone from Barack Obama to your teacher in school. Find every opportunity to speak English. 小题4: You will meet people like you there and it will help you realize that you are not the only person who isn’t good at this subject. Also meeting different people will help you overcome your complex. You can also join coaching classes, which will provide you professional help in learning spoken English. 小题5: Nothing is more beautiful than simplicity. So, instead of using an ambiguous(含糊不清的) language with tough words, go for simple words. Learning any new language is difficult and English is no exception. Start simple and go with the flow. With time, you would learn bigger words too. |
