三、教学评价
本节课是依据《英语课程标准》中四级目标要求,学习策略和情感态度五级的目标要求,按照“自主构建-语法聚焦-感知体验-自主运用”教学思路,对本节课的教学进行设计,确立了四个教学环节,情景导入,语法练习,听说读写,反馈纠正。
在导入环节,以看图片回答问题的形式,让学生增强文化意识,通过Around the world 吸引学生注意力,为学生介绍一次激动人心的经历,引起对本节课的兴趣,同时引导学生用现在完成时描述自己的经历。
在语法练习环节,通过导入后的练习,让学生自主概括,归纳现在完成时态的相关知识。
然后利用问卷调查的形式,让学生对小组内同伴用现在完成时的问句进行调查,将获得的信息填写调查表,锻炼了学生获取信息的能力。
在听说读写环节中,通过听的练习,培养学生识别具体信息的能力;通过阅读培养学生的语篇理解能力;通过写明信片,让学生将联系实际,将语言应用于实践生活,培养了学生表达的逻辑性和观察能力,也体现了对祖国的热爱之情。
在反馈纠正环节,针对所学模块知识,通过对应练习加以巩固,效果明显。
到本节课结束时,绝大多数学生能通过写作,深入地理解现在完成时态在生活中的语言运用,能流畅的描述自己及他人的经历。

Its size is its most noteworthy--and striking--feature and after that, I suppose, its trunk. An elephant's trunk is rather like an arm and a hand: it is used to pick up and put things in its mouth. It is alsoused to draw up water: either to drink or for the purpose of washing. Then we might note its skin, which is thick and almost hairless, and finally its tusks. These--the tusks, that is—are in fact teeth, which it uses for cutting. I will just mention those points again: its size, trunk (rather like an arm and a hand), skin (thick and hairless), and tusks. Elephants are gregarious (群居的)--that is to say, they live in herds--herds which number from about fifty to a hundred. The head of the herd is usually a female elephant, not a male. Elephants travel slowly, rarely going faster than fifteen to twenty miles an hour at the most, and when they move from one forest to another, they often travel in single column.Despite their size, elephants, surprisingly, are timid animals, although the male elephant can be fierce and even dangerous. They are not considered to be intelligent, but they do have good memories, and for that reason they can be trained and put to work, as we shall see below. They have a strong sense of smell, but they do not see or hear well. As for how long elephants live, this is not known exactly, but the general belief is that they are long-lived. In the wild, for example, elephants live for about fifty years, and in captivity (囚禁) they live for even longer periods.Elephants are vegetarian. They live mostly on grass, leaves and fruit. They are especially fond of bamboo shoots, for example, but they also eat the twigs and bark of trees. The quantity of food and water which they consume is enormous, and they can be very destructive in their search for food, in fact.1.

They are afraid they will be played jokes on by a bully. One study found that 52% of children reported being bullied at least once a week. Sixty percent say that they know someone who could harm them. One student was always being joked because he was short. He didn't like to go to school because he had to face the bullies.Some children choose not to go to school at all so they can avoid the bullies. When they miss school, students fall behind their classmates. A new program is helping put an end to this problem. The program is teaching kids how to deal with bullies. This is helping more children feel safe in school.One school principal is working to end this negative behavior. Last year, he decided to let students know bullying is not allowed there. Students are now encouraged to report bullies and stand up for themselves. Those found to be bullies face harsh penalties (处罚). Students at his school participate in a program called "Be Bold". In this program, students work together to prevent violence. They do skits and go into classrooms to talk about the problem. They give other students strategies (策略) on how to deal with bullies.The principal says that the school has changed since he has addressed the bullying problem. But there are other steps parents can take to help their children with this problem. First, students and their parents should know the school's rules about bullying and what they should do if it happens. Second, children should be taught to stand up for themselves. They should try to resolve issues by talking them out. If the problemcontinues, parents and children should record each incident. Children should tell someone if they are being joked. Many children keep bullying a secret.Parents should look for warning signs of bullying. These can include cuts and bruises (瘀伤), worrying, wanting to stay home from school, or a sudden drop in grades.6. What's the topic of the Fast paragraph?A. Bullies are a big problem in schools.B.
