PTE考生目前最大的问题之一就是练习题缺乏。除了有限的基本官方书（PLUS，Testbuilder, OG）之外，就没有题了。很多英语基础不是很扎实的同学很难找到练习材料。墨尔本文波雅思PTE培训学校专门为墨尔本，悉尼PTE考生准备了适合PTE听力阅读练习的科学60秒。各位PTE同学可以练习PTE听力中的summarise spoken text和PTE口语中的retell lecture，练习记笔记技巧和复述。废话少说，下面开始：
60秒科学：Baby-Talking Adults Boost Infant Word Production

[Baby talking]
It’s hard to resist. One look at those chubby cheeks, and the next you’re cooing: [man using baby voice] “Who’s a cute little baby?”
Now research finds that by using this style of speech to talk to babies, you may be helping their early language development. Adults using so-called baby talk provide particularly good phonetic examples—producing sounds that are clearer, longer and more distinct from each other.
Researchers used small digital recorders hidden in the vests of 11- and 14-month old babies to record the infants’ auditory environment. Thirty-second snippets were then analyzed to identify whether the parents used baby talk or regular speech, and whether speech occurred in one-on-one or group settings.
The more parents engaged in one-on-one baby talk, the more the baby babbled—which is a precursor to word production—and the more words they produced at age two. The study will appear in the journal Developmental Science. [Ramírez-Esparza, N.,García-Sierra A., & Kuhl, K. P. (under review), Look who is talking: Social variables linked to infants’ speech development.]
So parents, looks like if you chat regularly with your child, you’ll soon be saying, “look who’s talking.”
