13．What if our babies could somehow tell us what they're thinking about，what they want，and what makes them unhappy？Robyn Holt，researcher for Baby Talk New Zealand，says they can．Holt heard about baby sign language through an advertisement and decided to go along to a workshop （研討會）． "Sign language is something that's always interested me，and I thought，it could be really cool to try this with a baby because we are always guessing all the time what they actually want．" Holt started using baby sign language with her baby son Benjamin，now 12，and within two weeks he started to sign the sign for milk．She has since used it with her two younger sons Dominic，8，and Matthew，3． Baby sign language is nothing new：the practice （which is based on adult sign laguange） has been out in America for more than 30years．But it is enjoying a rebirth in New Zealand． The idea behind baby sign language is that babies do have the ability to communicate their needs if they are given the right tools to do so．Although many mothers develop an intuition （直覺） about whether their baby's crying is from hunger，tiredness，or pain，baby sign language creates a direct form of communication that unlocks the mystery． When babies are between 6-months and 12to 13-months，parents can begin to teach them sign language：use the sign for milk while feeding，and also talk about milk，so that the child begins to make the link （關(guān)聯(lián)） in their brain．Then they can begin to add other signs，i．e．food，sick or pain． "I know of one parent．Her child was signing the sign for hurt by his month，and she realized his first teeth were growing．It makes life so much easier，"said Holt． 25．Why did Holt go to the baby sign language workshop？B A．To entertain her own children． B．To better understand babies'needs． C．To help babies with language problems． D．To develop a new system of sign language． 26．According to the text，baby sign languageC． A．has been used in New Zealand for 30years B．can easily make the parents understood C．has developed from adult sign language D．was designed by Robyn Holt 27．What does the underlined part"the mystery"in Paragraph 5refer to？C A．The ability to communicate． B．Mothers'intuitions． C．The cause of the baby's crying． D．Baby sign language． 28．Holt mentioned a parent and her child to show baby sign language isA． A．helpful B．difficult C．interesting D．special．
