F Read and complete（读短文，完成任务）选做题
I'm Jake. There is a beautiful lake in our city. These days there is lots of rubbish near the lake. It makes the lake dirty.
This Saturday, I will clean the lake with my family. We will pick up the rubbish and put it in the bin. We will sweep the ground around the lake too. My sister and I will make some posters to ask people not to litter. We will work to make the lake clean and beautiful again.
1. 根据短文内容判断句子正误，正确写T，错误写F。
() ① The lake looks clean and beautiful these days.
() ② Jake will clean the lake with his classmates.
() ③ Jake will clean the lake this weekend.
2. 根据短文内容填空，每空一词。
① Jake and his family will around the lake.
② Jake and his sister will .

1. ① F ② F ③ T
2. ① sweep the ground
② make posters

【分析】本题分为判断正误和填空两部分，需结合短文内容逐一核对：1. 判断正误时，要找到每个句子在短文中的对应描述，对比是否一致；2. 填空时，需从短文中提取符合要求的动作短语，确保每空一词。具体来说，第1题①句提到湖现在干净漂亮，但短文说湖边有垃圾使湖变脏，故错误；②句说和同学，短文是和家人，错误；③句说这周末，短文是本周六（属于周末），正确。第2题①句对应短文“sweep the ground around the lake”，②句对应“make some posters”。
【解析】1. 判断正误：①短文第一段指出“These days there is lots of rubbish near the lake. It makes the lake dirty.”，说明湖现在不干净，故填F；②短文第二段提到“I will clean the lake with my family”，不是同学，故填F；③短文第二段说“This Saturday, I will clean the lake”，Saturday属于weekend，故填T。2. 填空：①根据短文第二段“We will sweep the ground around the lake too.”，填sweep the ground；②根据短文第二段“My sister and I will make some posters to ask people not to litter.”，填make posters。
【答案】1. ①F ②F ③T；2. ①sweep the ground ②make posters
