帮我看看句子有错吗?1.since i want to senior high school ,my life has

1、since当“自从”的意思时,它引导的这个从句要用过去时,“从……时候开始,我就……”因为我就……,这个动作一直延续到现在,所以这个主句应该要用现在完成时.你写的那个句子改成“Since I went to senior high school,my life has changed a lot.
2、因为是each year（每年）,所以要用一般现在时,因此came要变成come.
这句话改写成：Thousands of people come to Loch Ness each year to see the famous animal.(每年都有成千上万的人去Loch Ness去看这有名的动物）
或者改成：Thousands of people come to Loch Ness each year because they want to see the famous animal.(每年都有成千上万的人去Loch Ness,因为他们想看有名的动物.）
