假设你是红星中学高三一班的学生李华,为响应绿化祖国的号召,你班四月十二日去郊区植树,请根据以下四幅图的先后顺序,介绍植树活动的全过程,给某英文杂志的“绿色行动”专栏写一篇以Green Action in Our Class为题的英文稿件。

注意:词数不少于60。 提示词:郊区 suburb

_________________________________________________ ________________________________________________ ________________________________________________

[思路点拨]

1.学生应该认真阅读提示,把握准情景和要求,使表达的内容不走题,本题创设的是骑车去植树的一系列情景。

2.根据情境的发展,按顺序安排好材料。本题应该按照活动内容:骑车、路上——到达——植树过程描述——离开前照相——简短感想的顺序完成。

3.学生应该注意层次分明,重点突出。本题的表达重点要放在植树的过程上,去的路上和植树后以及感想是次要的;可以按照三个层面写(1)植树路上;(2)植树过程;(3)植树完后和感想。

[范文]

Green Action in Our Class

April 12th is memorable because our class had a meaningful experience on that day. In the morning, we bicycled to the suburbs to plant trees, talking and laughing all the way. Upon arrival, we began to work immediately. Some were digging holes. Some were carrying and planting trees. Others were watering them. After getting the work done, we put up a board reminding people to protect the trees. Before leaving we took some photos to record our green action. Seeing the lines of trees, we all had

a sense of achievement. We all think it's our duty to protect and beautify our environment.

2.anyhow/anyway adv.

(1)“无论如何,不管怎样;总之;尽管如此”。在作此意讲时,anyway和 anyhow一样,都用做让步状语,一般置于句中(其前常有连词 but)或句末。

(2)“况且,更何况,再说,至少”。作此意讲时,两者都可用来做状语,对前面的话做补充,给出一个令人信服的理由,此时 anyhow常出现在句首或最后的分句之首,而不出现在句末。

(3)“粗心地,随意地”,作此意讲时,只能用 anyhow。

[即学即练2]写出下列句中anyhow的意思。

(1)It may rain, but we shall go anyhow.______________

(2)Anyhow, you can try, even if there's not much chance of success.___________________________

(3)The work was done all anyhow._________________ 无论如何 至少 粗心地
