Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”; “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.

2.由于附近金礦生產(chǎn)廢棄物尾礦砂的堆積,孫家村的大溝里十幾年來(lái)就吃掉了近百畝土地,使人均耕地下降到0.03公頃。村里和礦上共同商量,共同開(kāi)發(fā)復(fù)墾,由礦上出錢,村里出勞力、機(jī)械,運(yùn)來(lái)“客土”覆蓋到尾礦填平的溝壑上,形成耕地。十年來(lái),通過(guò)這種方式恢復(fù)耕地15.335公頃,不僅解決了尾礦污染問(wèn)題,而且村里耕地由25公頃多增加到40公頃。【思考】分析以上兩個(gè)例子,哪一個(gè)體現(xiàn)了可持續(xù)發(fā)展的原則,為什么?【分析】第二個(gè)材料體現(xiàn)了可持續(xù)發(fā)展。因?yàn)椴牧?用農(nóng)田堆放垃圾會(huì)破壞土地肥力,影響農(nóng)業(yè)生產(chǎn),又污染環(huán)境,危害村民健康。這種行為目光短淺,只顧眼前利益,沒(méi)有考慮長(zhǎng)遠(yuǎn)發(fā)展。材料2既解決了尾礦污染問(wèn)題,又增加了耕地面積,耕地是可再生資源,利用得當(dāng),可為村民提供農(nóng)產(chǎn)品,解決溫飽同時(shí)創(chuàng)造經(jīng)濟(jì)效益,達(dá)到良性循環(huán)。所以說(shuō)保護(hù)環(huán)境就是挽救人類,我們要將這種意識(shí)轉(zhuǎn)化為自身行為,使人地關(guān)系走向和諧。
