Be sure to make reservations if the restaurant you chose is fancy or popular one.It's very embarrassing to show up without reservations and have to wait for a table,leaving a very bad impression on your date.
【正确答案】：如果没有订座位就去了，为就餐座位而排队等候，委实尴尬，还会给约会对象留下极差的印象。【解析】原句中it是形式主语，真正的主语是不定式to show up without reservations和 have to wait for a table；汉译时增译“如果"；embarrassing在原句中作表语，位于句首，汉译时则后置于两个谓语结构之后，作评价和总结；leaving a very bad impression on your date是现在分词短语作结果状语。
