Part 2 4 some In addition to these physical capabilities, experimental results show that babies' intelligence is often superior to adults'. Because of the way human brains develop, six-month-old babies are better at recognizing certain faces than adults. But there is a 5 catch: it is non-human faces that they really excel at recognizing. In another study, researchers discovered that six-month-olds had no problem distinguishing individual monkeys, although they look almost the same to adults. NIVEL どんな点で赤ちゃんは大人よりも優れているのでしょうか。 10 5 Researchers have also found that babies, before six months of age, have the ability to hear and distinguish between almost all the sounds of human languages. That's about 150 sounds in about 6,500 languages! For instance, Japanese babies can hear the 15 difference between "r" and "1" sounds, which adult Japanese find difficult to distinguish. This ability will disappear gradually as they learn their native language, Japanese. capabilities (kelpabila <capability keipobilan experimenta liksperament intelligence (inteladzana) superior [saplariar recognizing (rékagnaizin) <recognize (rékagnaiz) non-human \nànhjú:man excel [iksel] distinguishing [distingwif(in) idiom 2 be superior to 8 six-month-olds = six-month-old babies 5 there is a catch ここには留意すべき点があります !? 赤ちゃんの際の記憶が定かでないのは、人の記憶は3歳以降に定着するためであるという説があります。

テーマ 資源・エネルギー 10 文法項目 動名詞(いろいろな形/動名詞と不定詞) Track 29-30 UNIT 6 Reading URELL パンダのふんの研究が、いつの日か環境問題の解決に寄与するかもしれません。 In June, 2016, a baby *giant panda, Tian Bao, was born at a zoo in Belgium. It became big news because the birth of a baby panda is an *extremely Actually, that of Tian Bao was only the sixth in Europe in the last 20 years. While its population is slowly increasing, the giant panda remains one of the rarest animals 5 in the world. Therefore, scientists have been doing research on how pandas have babies. So, you may think the scientists working at the Belgium zoo *accomplished the goal of their research. But they have another goal; apart from having done that research, they've been studying panda *poo. Why are they doing that? Bm Dimoda ro Tian Bao's mother Hao Hao and its father Xing Hui live in the same zoo as their baby does. While they enjoy sitting in the sun and eating bamboo, with ow dirg.or the scientist team collects their poo. By studying the poo, the team is aiming to understand how pandas can digest bamboo. rare event. 2 Note In fact, bamboo is receiving a lot of attention in biofuel research these days. 15 It's among the fastest-growing plants on earth, and yet needs the least care. So the plant can become a good source of *renewable energy. But because bamboo is very tough and hard to *degrade, today's method for making a biofuel from bamboo costs a lot. *Technically, pandas are meat-eating animals, but over the years the food they eat 20 has changed to almost only bamboo. The scientists are trying to find the *microbes that help a panda digest about 10kg of bamboo a day. By using these microbes, they will be able to discover an easy and cheap method for ( 4 ). It may take time, but some day panda poo may help cars run. (296 words)
