    Can plants learn and remember? Monica from Australia thinks so.

    Monica and her team members did some tests on mimosas(含羞草). The plants close their leaves quickly when people touch them. They put some mimosas in 56 pots. Every time they dropped the pots from 30cm high, the plants closed their leaves. Monica and her team members did this for a whole day. To their surprise,at the end of the day, the plants didn't close their leaves at all. It seemed that the plants learned that this action wouldn't hurt them.

    Another amazing thing was that the plants might remember things for a long time. Monica dropped the same pots of mimosas four weeks later. The plants still didn't close their leaves.

    Monica wasn't sure how plants learned and remembered. "The plants don't have brains, after all. Maybe they learn and remember with the help of their cells(细胞)," she said.

A、they make some sounds B、they open their leaves C、they close their leaves D、their leaves drop
(2)、How long did it take Monica to do the test at first?

A desert is a place where almost no rain falls. Only plants and animals that need very little water can live in a desert. Here are two types of deserts.

Sandy deserts are covered in hills of moving sand called dunes (沙丘). Very few plants grow in these hot and dry places. Camels (骆驼) are the desert animals. {#blank#}1{#/blank#}. A camel can go for days without food or water. It lives on the fat stored in its hump (驼峰). {#blank#}2{#/blank#}. These camels usually live in the desert of Africa and Australia. And some camels have two humps on their back. They live in Asia where the desert is cooler. They are known as Asian camels. A camel usually has thick eyelashes to protect its eyes from sand blown by the wind.

In some deserts, the land is rocky. They're called rocky deserts. Plants can store their own water grow in the dry and rocky deserts of North America. Rattlesnakes (响尾蛇) live in rocky deserts. A rattlesnake gets its name from the rattle (响环) on the end of its tail. {#blank#}3{#/blank#}. Most cacti (仙人掌) grow in rocky desert. They grow very slowly, but they can live for 20 years. {#blank#}4{#/blank#}. Some types of owls like to build their homes in them.

A. Some camels have only one hump

B. Many of them can grow taller than a house

C. Humps are really important for an adult camel

D. They help people carry things across the desert

E. It shakes its tail from side to side to warn other animals to stay away

 In a new study, researchers found a fact. Whether it's sports practice, music lessons or a usual catch- up with friends, when children are doing after- school activities, they may feel happier and healthier than those who always look at a screen.

 What's more, children's happiness improved when they joined in after- school activities, while things were completely  when they spent time on social media (媒体) or playing video games.

 The researchers studied 61,759 school students from Grade Four to Grade Nine. They worked out how many days every week children joined in after- school activities from 3:00 pm to 6:00 pm. Then they compared the number to well- being factors (幸福的因素 ) like satisfaction, sadness and worry.

 Lead researcher Dr. Rosa Virgara said the research showed how some out- of- school activities can improve children's happiness, while others, especially screens, can be bad for their mental(精神上的) and physical health." Screens are a big distraction(分散注意力的事物) for children of all ages. Whether children are playing games, watching TV or using social media, there is something about all screens that hurts their happiness," she said.

 The study also showed that even children who were already happy also benefited (得益于) from joining in after- school activities." This shows that there is a big need to find ways to encourage children of all ages and backgrounds to join in activities that keep them away from TVs, computers and smart phones," Dr. Rosa Virgara said.
