         Most people consider mushrooms to be the small,ugly cousins of the plant kingdom,but some of them are surprisingly beautiful and wonderful waiting to be explored.

Sky Blue Mushroom 

         Sky Blue Mushroom is a species of mushroom found in New Zealand and India. The small mushroom has a distinctive all-blue color,while the (菌褶) have a slight reddish color. Sky Blue Mushroom is not eatable because it is poisonous. This species was one of the six native fungi (真菌)featured in a set of fungal stamps issued in New Zealand in 2002. It is also seen on the $50 bank note issued by the Reserve Bank of New Zealand in 1990.

Veiled Lady Mushroom 

          This delicate and strange mushroom can be found in gardens and woodlands in southern Asia,Africa,Australia and the Americas. This eatable and rather healthful mushroom is used in Chinese cuisine. While the lacy (似蕾丝的) skirt is what draws our eyes,the mushroom actually uses the cap to draw attention,too.

Bioluminescent Fungi 

          This green mushroom emerges during the rainy season in Japanese and Brazilian forests. The bases of tree trunks,fallen branches,leaf litter and slightly wet soil provide perfect growing grounds for the mushroom. The appearance of these bright-looking fungi is due to bioluminescence (生物发光) , one of the strange but wonderful reactions that happen naturally in many plants and animals.

Red Cage Fungus 

          The mushroom is known as the red cage,referring to the striking fruit body that is round and empty inside with latticed(花格状的) branches. Feeding off woody plant materials,this mushroom can be found growing in leaf litter,grassy places or on garden soil. Though it isn’t  clear if it is eatable,apparently its smell is enough to prevent anyone interested from eating it.

             Elephants have strong defenses against cancer that can prevent it forming,say scientists. They were trying to explain why the animals have lower levels of cancer than would be expected considering their size.

             People think that every cell can become cancerous,so the more of them you have,the more likely you are to get cancer. So if an elephant has 100 times as many cells as a person,then it should be 100 times more likely to have the disease. And yet the analysis showed only 5% of elephants die from cancer compared to up to 25% of people.

            The scientists turned to elephants’ DNA. Cancer is caused by mutations (变异) in a ceir s DNA that produce faulty instructions leading to (遏制不住的) growth. But animals also have “smoke alarms” that detect the damage and lead to the cell being repaired or killed. One of these alarms is called TP53,and while humans have one TP53 gene,elephants have 20.As a result,elephants seem far keener to kill off cells.

             But Mel Greaves,from the Institute of Cancer Research in London,said, “We should focus on why humans have such high levels of cancer. In terms of adaptive mechanisms (机制) against cancer we have the same as chimps,but a lot more humans get cancer than chimps. I think the answer is that humans are completely unique as a species in having very rapid social evolution (进化) in a short period of time." He pointed to the rise of unhealthy,cancer-causing behavior,such as obesity and sunbathing. “You’ve never seen an elephant smoke!” he added.

             In an evolutionary sense, “success” is judged by the number of kids you have rather than how long you live. Elephants have the greatest reproductive success towards the end of their lives,while humans can live for decades after we are no longer able to getting pregnant. It means there is little evolutionary pressure in humans to develop ways of preventing cancer in old age.

           Last week,we took part in a press conference at NASA’s Johnson Space Center promoting the release of The Martian movie. We spoke with several NASA officials and an astronaut about their plans to help humans set foot on Mars. They all shared with us the big challenges ahead in order to accomplish that. However,it is something they take seriously,and are determined to achieve.

           In an interview at Space Center Houston,The Martian producer Aditya Sood told us the experience of working on the movie with NASA employees was amazing. He said he enjoyed interacting with folks who tried to solve a lot of difficult problems every day. We got an idea of what Sood was talking about when we interviewed some of the scientists responsible for getting humans to Mars.

           Planetary Science Division Director Jim Green told us that getting humans on the surface of Mars in 2035 is probably too ambitious. They are actually looking to get a “human presence in the neighborhood” by the 2030s,meaning in Mars* orbit. Their goal for landing on Mars is for the 2040s or 50s.

           The spacecraft that will take humans to Mars will be the Orion. It is not quite as futuristic-looking as the spaceship in The Martian. In fact,the Orion looks more like the spacecraft that took us to the moon. However,according to their website ,“NASA’s Orion spacecraft is built to take humans farther than they’ve ever gone before."

           When asked if they will really be ready to go to Mars in the 2030sr Stu McClung,the manager of Mechanical,Pyrotechnic,Landing and Recover Systems,told us with confidence and pride,MMy capsule will be ready!” Although,he did make that statement with a bit of a wry smile(苦笑) .That is because he adfnits they still have a lot to figure out.

9. What does the underlined word “that” in Paragraph 1 refer to?

   A. The press conference.

   B. Taking humans to Mars.

   C. The release of The Martian.

   D. Speaking with NASA officials.

10. After interviewing some scientists,the author realized that.

   A. Aditya Sood had been lying

   B. making The Martian wasn't so difficult

   C. working with NASA employees was successful

   D. NASA employees really faced a lot of challenges

11. What does Jim Green think they can achieve by the 2030s?

   A. Helping humans land on Mars.

   B. Taking humans into Mars,orbit.

   C. Finding the landing spot on Mars.

   D. Learning about the neighborhood of Mars.

12. What do we know about the Orion?

   A. * It can be seen in The Martian.

   B. It once landed on the moon.

   C. It has an amazing look.

   D. It will land on Mars.
