云服务相当于云端的存储空间,可以把重要的图片、文件等资料,备份到云存储空间,以免丢失的。可以打开云服务登录OPPO账号,备份联系人、信息、第三方软件、上传照片到云相册等进行备份哦。还可以打开云服务里面的找回手机功能,联网就可以定位了哦。两词均可作名词表示“选择”,但在意思与用法上存在着异同。(1)alternative,可数名词,它只有两个用法,一是表示“可作的选择”或“选择的余地”,也可理解为“选择的可能性”,此时,它可与choice互换使用。如:one of the alternatives open to you is to resign.you have the alternative of marrying or remaining a bachelor.caught in the act, he had no alternative but to confess.二是表示这种选择是用以“替代的东西或办法”。此时须注意,其后与它搭配的介词是to。如:what was the alternative to going home?the only alternative to it are gas and candles.the alternative to being taken prisoner was to die fighting.(2)choice除了和alternative一样表示“可作的选择”、“选择的余地”外,还可表示“选择的行为”、“选择的权利”、“选中的人或物”或“供选择的种类或范围”。如:what influenced you most in your choice of career? (选择的行为)if i had the choice, i would retire at thirty. (选择的权利)she wouldnt be my choice as prime minister. (选中的人)theres no much choice in the shops. (供选择的种类或范围)(3)除作名词外,两个词均可作形容词,alternative意为“可用以代替其它事物的”、“另一可选用的”、“其他的”。如:have you got an alternative suggestion?the alternative book to study for the examination is “war and peace”.choice作形容词则表示“精选的”、“高级的”。如:the shop was selling choice apples so i bought a pound.
