All these problems are very serious

• Learning objectives
  • 1.Tell how sandstorms come into being.
  • 2.Know the functions of trees.
  • 3.Think about ways of protecting trees.
  • 4.Writing a proposal to call on people to protect trees.
• Teaching methods
  • Task-based language teaching（TBLT）
  • The situation method
  • The Audio Lingual method
  • The cognitive method
  • The communicative language teaching
• Teaching procedures
  • step1: Look and talk about how sandstorms come into being.
    • teaching activity:Give the students six pictures and ask them to rank them.
    • teaching purpose:Learn how dust storms form.
    • teaching effectiveness:The students can sorted correctly and understood the formation process of sandstorm.
  • step2:First ask the students to predict the content of the listening according to the pictures, and then start listening.
    • teaching activity:The students listen and answer the questions. The teacher guides the students to give the correct answers.
    • teaching purpose:Let students know the causes of sandstorms and how to deal with them effectively. Students get enough thinking, know how to protect the ecological environment in the future.
    • teaching effectiveness： exercising students' listening skills effectively.
  • Step3:Listen again and complete the mind-map of the sandstorm.
    • Teaching activity：Complete the fill in the blanks based on the listening materials and summarize the knowledge about sandstorms from three aspects: facts, reason, and result.
    • Teaching purpose：Enable students to understand the causes and impacts of sandstorms.
    • Teaching effectiveness：Students have a more diverse understanding of sandstorms.
  • Step4:Read for the function of trees and share more ideas in your group.
    • Teaching activity:Firstly,find your partners.Secondly,play the roles as loud as possible.Thirdly,underline the sentences of functions.
    • Teaching purpose:Enable students to develop their oral skills and enrich their knowledge of tree functions through communication.
    • Teaching effectiveness：Through group dialogue and mind mapping, students have effectively developed their communication and drawing abilities.
  • Step5:Retell 1a with the help of mind-map.
    • Teaching activity：Complete the mind map on the blackboard by reading the materials, and invite classmates to come up and talk about this process, outlining the logical sequence.
    • Teaching purpose：Let students understand the relationship between sandstorms and tree planting, and analyze this causal relationship in their own words from a more logical perspective.
    • Teaching effectiveness：Not only does it exercise students' summarizing and analyzing abilities, but it also enhances their oral expression skills.
  • step6:How to protect trees？Let students create a mind-map in group work.
    • Teaching activity：Encourage students to divide tasks and collaborate in groups, drawing mind maps from four roles: organizer, writer, painter, and sharer.
    • Teaching purpose：Exercise students' ability to discuss, collaborate, and complete various tasks.
    • Teaching effectiveness：Students can share their ideas each other and cooperate well Which can exercise their group collaboration ability.
• Blackboard design
  • use stick figures show the relationship between sandstorms and environmental protection
  • Strengthen the relationship between humans and nature
  • using the mode of group competition, which group gets the correct answer will plant trees for which group. The group with more trees will win and stimulate students' learning enthusiasm.
• Homework design
  • Try to be a writer
  • Write a proposal to call on people to protect the trees
  • Self evaluation
