Tanghulu is 　2　(common) made of haws(山楂果),which are rich in vitamin C and are known 　3　(have) traditional Chinese medicinal properties.According to a legend,in the Song Dynasty,one of the emperor’s 　4　(wife) was sick and had 　5　 poor appetite.The doctor suggested that she eat five to ten haws 　6　(boil) with sugar before each meal.She recovered within half a month.Later,the prescription was passed on 　7　 ordinary people. 
People put haws on a stick,dipped them in hot sugar syrup(糖浆) and dried.The syrup finally turned into a solid coating,like the crystal on the surface of haws.That is 　8　 they are also called bingtanghulu.　9　 origin story says that the very first tanghulu only had two haws—a small one on the top and a big one below,making it resemble a hulu,a bringer of good luck.

（B）
1.has been　考查时态。根据本句中的时间状语“Since ancient times”和语境可知,此处应用现在完成时,故填has been。
2.commonly　考查副词。分析句子结构可知,空处作状语,应用副词形式,故填 commonly。
3.to have　考查非谓语动词。分析句子结构可知,此处应用动词不定式短语“to have traditional Chinese medicinal properties”作主语补足语。
4.wives　考查名词。根据空前的“one of”可知,这位皇帝的妻子不止一位,故空处要用可数名词的复数形式。
5.a　考查冠词。此处表示“胃口不好”,且poor的发音以辅音音素开头,故应用“a poor appetite”表示,故要用不定冠词a。
6.boiled　考查非谓语动词。该从句中已有谓语动词,故空处应用动词的非谓语形式,设空处与haws之间为逻辑上的动宾关系,故此处用过去分词短语“boiled with sugar”作其后置定语。
7.to　考查介词。 pass sth on to sb意为“把某物传给某人”,是固定用法,符合语境。
8.why　考查表语从句。根据语境可知,“The syrup finally...on the surface of haws”与“they are also called bingtanghulu”之间存在因果关系,故此处用why引导表语从句。
9.Another　考查限定词。根据第二段第二句中的“a legend”并结合语境可知,此处在讲另一个有关糖葫芦起源的故事,故填限定词Another。
10.reminds　考查动词的时态和主谓一致。根据时间状语“often”和句意可知,该从句的谓语动词要用一般现在时,且which引导的定语从句修饰先行词“a combination of flavors”,故该从句的谓语动词用单数形式,故填reminds。
