{#blank#}2{#/blank#}Air conditioners are usually set at too low temperatures in summer.

{#blank#}3{#/blank#}A lot of water is wasted by using too much.

{#blank#}4{#/blank#}We'll have less and less gas to use because more people buy cars.

A. Try our best to make friends with the countries in the Middle East and ask them to give us more gas in the future.

B. We should walk to work, ride a bike to school, and take a bus home more often instead of driving cars.

C. Encourage people to do more outdoor activities in their free time. Get children to learn more from reading books.

D. Plants more trees and grass around our houses. Ask people not to cut down the trees. Use your handkerchief instead of using paper napkins.

E. In rooms where you have an air conditioner, you can save electricity by cleaning the filter (滤波器). A filter uses 30% more energy when it is dirty. Also, set the air conditioner at 26 degrees.

F. Always keep the saying in mind "Turn off lights before leaving."

G. Take a shower instead of a bath, for a bath uses twice as much as water. Don't flush (冲洗) the toilet unnecessarily.

Tip 1

    You have to show up, which can be a challenge for many of us. You can show up as an observer(旁观者) of other interesting people and let that be a learning experience for you, Before you start talking, it's important to just listen, even if you think you are a wise storyteller. If you are close to a group of people who are discussing a topic, watch their body language and see if they will let you join in their conversation.

Tip2

    You'd better go in the conversation with a couple of topics to keep it going, or questions to, ask if there is a short stop. Simple things like "How do you know the host?" and "How did you get there?" are always good conversation starters to a certain extent(在—定程度上).

Tip 3

    Don't fear silences. Awkward(令人尴尬的) silences are common part of talking with people. Just rush to fill them. If you don't want to go on with the conversation, just say you are going to get another drink or something to eat, and find another group to talk with.

Tip 4

    Relax If you cannot keep a conversation going, or you don't know what you should say next, give yourself a little time to clear your head. Relax, and then turn back into the discussion.
