A.Speaking bravely. B.Writing to foreign friends.
C.Reading aloud. D.Listening to the teacher carefully
B
Welcome to Words and Their Stories. Today we talk about cake. It’s a kind of dessert made from flour（面粉），butter，sugar and icing（糖霜）.
Cake is a commonly served sweet treat at celebrations.And the word also appears in several English idioms（习语）.We’ve learned the idiom to have one's cake and eat it too, which means you don’t have to choose between two good things. And sell like hot cakes means sell quickly or in great numbers. Another expression is a piece of cake and it describes something that is very easy to do.
Most cakes are made up of two parts: the part made from flour and icing. However, a cake without the sweet icing on top is already great.After all, it’s made with lots of butter and sugar. So the icing is not really necessary. But it makes the cake extra special. That is the meaning of the idiom the icing on the cake. Something already good becomes better because of the addition of something else.
Let’s hear an example. Amy is in her new school and she loves her new teachers. So having her best friend as her classmate is the icing on the cake.


20.My favourite book is the Little Prince written by the __________________ (France) writer Antoine.
三、同义句转换

2.When Tom is with me, I never feel bored and lonely.

A．①、②、③中依次盛装溶液、浓、焦性没食子酸溶液
B．装置Q(启普发生器)也可用于二氧化锰与浓盐酸反应制备氯气
C．结束反应时，先关闭活塞K，再停止加热
D．管式炉加热前，用试管在④处收集气体并点燃，通过声音判断气体纯度
【答案】D
【分析】H2还原WO3制备金属W，装置Q用于制备氢气，因盐酸易挥发，则①、②、③应分别用于除去HCl、H2S、氧气和水，得到干燥的氢气与WO3在加热条件下制备W，实验结束后应先停止加热再停止通入氢气，以避免W被重新氧化，以此解答该题。
【详解】A．气体从焦性没食子酸溶液中逸出，得到的氢气混有水蒸气，应最后通过浓硫酸干燥，故A错误；


C．固体在空气中迅速变成灰绿色，最终变成红褐色，发生反应：，C正确；
D．硫氧化性较弱，铁粉与硫在加热条件下生成，D错误；
