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.

《數(shù)學(xué)1必修本（A版）》的第五章4.5.2用二分法求方程的近似解．本節(jié)課要求學(xué)生根據(jù)具體的函數(shù)圖象能夠借助計(jì)算機(jī)或信息技術(shù)工具計(jì)算器用二分法求相應(yīng)方程的近似解，了解這種方法是求方程近似解的常用方法，從中體會(huì)函數(shù)與方程之間的聯(lián)系；它既是本冊(cè)書(shū)中的重點(diǎn)內(nèi)容，又是對(duì)函數(shù)知識(shí)的拓展，既體現(xiàn)了函數(shù)在解方程中的重要應(yīng)用，同時(shí)又為高中數(shù)學(xué)中函數(shù)與方程思想、數(shù)形結(jié)合思想、二分法的算法思想打下了基礎(chǔ)，因此決定了它的重要地位．發(fā)展學(xué)生數(shù)學(xué)直觀、數(shù)學(xué)抽象、邏輯推理和數(shù)學(xué)建模的核心素養(yǎng)。課程目標(biāo) 學(xué)科素養(yǎng)1.通過(guò)具體實(shí)例理解二分法的概念及其使用條件．2.了解二分法是求方程近似解的常用方法，能借助計(jì)算器用二分法求方程的近似解．3.會(huì)用二分法求一個(gè)函數(shù)在給定區(qū)間內(nèi)的零點(diǎn)，從而求得方程的近似解． a.數(shù)學(xué)抽象：二分法的概念；b.邏輯推理：運(yùn)用二分法求近似解的原理；
