參考答案:1.“It'll be fun to take a walk by____sea,”she said,with____look of happiness.
A.a;a B.the;/ c.the;a D.the;the
选C：by the sea表示“在海边”，by sea表示“由海路”，题意显然是在海边散步；look此处意为“表情”，用a来修饰一种表情。
2.Classical British children's books____extra sales because of"Harry Potter" in these years.
A.are getting B.gets C.is getting D.get
选A：从时间指示词“these years”（这些年来）判断用现在进行时态比较合适，表示“这些年来一直...并且还会持续下去”的意思
3.Some people collect stamps just for fun.However,____people collect stamps that they think will make them rich in the future.
A.other B.the other C.another D.others
选A：此处“other”仅仅作修饰用，表示“一些其他人”；the other特指“两者中的另一个”；another表示“另一个”，与题意不符；others是名词性的，表示其他人的总体，不能用于修饰people。
4.In Mongolia,dogs are highly respected.Tradition says that the new tooth_____in good condition if the baby tooth is given to a dog.
A.grows B.is grown C.will grow D.grew
选C：由于从句if是一个对现在的假设，故在这个假设上发生的主句还没有发生，用将来时。
