选哪一个答案

Though he is _______worker he works Linda is going to ______the small get-together. Linda is very sad___what you've said to her This is Linda speaking为什么不是This is Linda's speaking?我认为原来那句好象不符合语法 even though the object is changed,but friends is here Though Ana just is a little fatter than Sue. even though he is but a passing acquaintance Linda is writing a litter to her pen pal.(改否定句) ____ Linda is shy , _____ she doesn't like talking.
