1.B
句意为“不要让它（这个消息）为他人所拥有/持有”,所以用in the possession of sb = in one's possession.
而in possession of的意思是“拥有/持有某物”,这样it就必须是of的宾语；
同样,in charge of的意思是“主管/负责/照料某物”,in the charge of意思是“为某人所主管/负责/照料”,句意不通.
2.B
此句是一个so...that...句型,而that所引导的结果状语从句my cellphone of out-of-date中,又含有一个非谓语结构所充当的时间状语.
考虑到句子主语my cellphone和非谓语动词use之间的被动关系,所以必须使用表示被动的结构.
A为主动；C也为主动（它是表主动的using的完成形式,并非表示被动）；而D为谓语结构,不能做状语.
只有B表示my cellphone和use之间的被动,它是完成形式,表明be used该动作发生在谓语动词is out-of-date之前.
3.A
natural gas“天然气”和wind“风”都是energy“能源”的形式（form）.
source表示“来源/源头/源泉”,power表示“力量/权力/动力”,material表示“物资/材料”.
