This means moving your eyes quickly down
the page to find specific information.It is 8：30 a.m. at the Chengdu Research Base. Panda keepers are preparing milk for the baby pandas’ breakfast. At 9：00 a.m.， they find that most ofthe babies are already awake? and hungry. When the babies see the keepers， they run over to them with excitement and some of the young pandas even walk into their friends and fall over?！Lin Wei，one of the panda keepers，says “They’re so cute and lovely. I take care of them like they’re my own babies. I wash， feed and play with them every day. They're very special to me.” In fact，many people around the world love these black and white animals. Pandas have become so popular that they are now a symbol of China.Scientists say there are now fewer than 2,000 pandas living in the forests. ?Another 300 or so ? live in zoos or research centers in China and other countries. Pandas do not have many babies， maybe only one every two years. The babies often die from illnesses and do not live very long. Adult pandas spend more than 12 hours a day eating about 10 kilos of bamboo. Many years ago， there were a lot more bamboo forests and pandas in China， but then humans started to cut down these forests. As the forests get smaller and other human activities cause more problems，pandas cannot find enough to eat and they are having fewer babies.An education program in Chengdu
teaches children about pandas and other endangered wild animals. They send
people to schools to tell children about
the importance of saving these animals.And the Chinese government is trying hard to help save the pandas. Scientists are doing research to better understand the habits of pandas. We all hope that in the future there will be a lot more pandas. awake/??we?k/ adj.醒着知识点4awake此处用作形容词，意为“醒着的”，它在句中
常作表语。反义词是asleep。

Please wake me up at six in the morning.
请早上六点叫醒我。典例After working all night， Kate couldn’t stay ____________the next morning.（wake）（盐城）awake fall over绊倒知识点5【辨析】fall down，fall off和fall over这三个短语都表示“摔倒、跌倒”的意思，但它们各自的含义不同。考向eg：I saw the little girl fall over.
我看到这个小女孩跌倒了。
The boy hit the tree so hard that he fell down.
男孩重重地撞在树上，结果自己倒下了。
The girl is falling off the bike.（＝ The girl is falling down

2,000 pandas living in the forests.科学家说现在有不到2000只大熊猫生活在森林里。“There be＋ sb./sth.＋doing sth.＋地点”表示“某地有某人或某物正在做某事”。其中doing sth.是后置定语，与其修饰的词是逻辑上的主谓关系，表示人与动作是主动关系。知识点6考向eg：There is a truck collecting the rubbish over there.
在那边有一辆卡车正在收垃圾。
There are some people picking apples on the farm.
在农场上有一些人正在摘苹果。典例—There are some boys ________ basketball over there.
—Let’s go and join them.（恩施）
A. are playing B. playing C. to play【点拨】本题用固定句式法。句意：有一些男孩正在那边
打篮球。固定句式：There is/ are sb./ sth.doing sth.有某人/某物正在做某事。B 在there be句型中，当主语为多个并列的名词时，be动词的形式与离它最近的名词保持一致，即遵循“就近原则”。
eg：There is a science lab and two libraries in my
school.＝ There are two libraries and a science
lab in my school.
我的学校有一个科学实验室和两个图书馆。拓展【难点】or so大约or so意为“大约”，常用在被修饰词后，而about，around表“大约”时，常用在被修饰词之前。
