    Space vegetables are grown from seeds(种子) that have been taken to space and brought back to the earth. The seeds are affected by the radiation(辐射)and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy.

    Here are some facts that you should know about space vegetables.

Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space they are tested to make sure that they will be safe to eat.

    Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes。

    After genetically modified (转基因)food appeared in the market, people worried that they were eating unknown things. For example, if nut genes(坚果基因) are put inside potatoes, people allergic(过敏的) to nuts might get sick from eating these potatoes because they do not know they are also eating nuts. Unlike genetically modified food, space vegetables have not been genetically changed. This means that no new genes are put into the vegetables. Therefore, there are no dangers of eating unknown.

(1)、According to Paragraph One, how are the space vegetables?
A、More delicious. B、Healthier and bigger. C、More dangerous. D、Cheaper and healthier.
(2)、According to Paragraph 4, how long can normal tomatoes stay fresh?
A、For seven day. B、For twenty days. C、For thirteen days. D、For twenty-seven days.
(3)、What's the difference between space vegetables and genetically modified food?
A、Space vegetables have no new genes. B、Space vegetables are grown in space. C、Space vegetables have nothing unknown. D、Space vegetables are genetically changed.
(4)、What does the writer want to tell us?
A、The seeds of space vegetables are taken to space. B、Everybody worries about eating space vegetables. C、Space vegetables are safe and good for people to eat. D、Space vegetables bring us illness because of the radiation.

    Would it surprise you to learn that, like animals, trees can communicate with each other and pass on their wealth to the next generation--their young trees?

    Suzanne Simard, forest ecologist at the University of British Columbia, explains how trees are much more complex than most of us ever imagined. Simard and her colleagues have made the major discovery that trees and plants really do communicate and interact with each other.

    Trees live on through their group work and support, passing around the resources such as nitrogen and carbon “depending on who needs it by miles of underground fungi(真菌) networks. This makes sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This system works in a very similar way to the networks of neurons(神经元) in our brains, and when one tree is cut down, it affects all.

Simard talks about "Mother Trees". These are the largest, oldest trees that rise above the forest, a concept explained in the movie Avatar. These “Mother Trees" are connected to all the other trees in the forest by this network of fungi, and may manage the resources of the whole trees and plants in the forest. She explains how these trees pass on the wealth to the next generation, transporting important resources to young trees so they may continue to grow. When humans cut down "Mother Trees" without paying attention to these highly complex "tree societies” or the networks on which they feed, we are losing the chances to save the whole forest.

    "We didn't take any notice of it,” Simard says sadly. “Mother Trees move nutrition into the young trees before dying, but we never give them a chance.” If we could send this message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

Do you know what the body mass index(BMI, 体重指数)is? According to the National Health Service, BMI is a measure(测量方法)that uses your height and weight to work out if you are fit. 

Some cities in China have included BMI in the PE test for the high school entrance examination, or zhongkao. For example, Beijing in 2021 announced that BMI officially became a subject of the PE test for the zhongkao. Chengdu and Shanghai have also started similar actions. BMI in cities like Xiamen, although not included in the zhongkao, still plays a role in regular PE tests. 

Zhang Yanshu is a grade 8 student from Beijing Chaoyang Foreign Language School. He used to be overweight. "It was this summer that I decided to work on my BMI, " Zhang said. He started by running with his dad, and soon took a stamina(体能)course which trained him for different things like running, pull-ups and so on. "I think BMI and the events for the exam go well together. When I practice the events, my BMI gets better; when my BMI gets better, I feel more energetic(精力充沛的)doing the events. "

Zhang also paid much attention to his diet. "I ate brown rice instead of white rice, and chicken for meat most of the time, " he said. "It was for sure sad. " His BMI reached a normal level after four months of effort(努力)"My health and willpower(意志力)have seen a big improvement. "

Chen Kaifei, 14, also from Beijing said that BMI is also a problem for students who are too thin, and has caused some"figure anxiety(身材焦虑)"among students. "However, mostly I think it has a good influence, " Chen said. "Everyone has a better understanding of their body and health conditions, and I started to care about my diet and lifestyle every day, simply to keep my BMI at a good level. "
