【题目】 However exciting space travel sounds, astronauts must still suffer with bad food. Now, food in space has to be dehydrated(使脱水)or pre-cooked and stored. This means astronauts aren't really eating fresh food.
New technology may change this. Scientific American reports that a specially-designed oven will be sent into space this autumn with NASA's NG-12 cargo(货物).Far from the common vacuum-packed(真空包装的)meals, astronauts may get to enjoy freshly baked cookies before the end of 2019.
Why aren't they baking cookies in space already?
For one thing, there's the risk of a fire. Engineers also have to overcome the challenge of microgravity, which prevents heat from circling inside ovens the same way it does on Earth.
Astronauts will still have to wait a while before they can have their cookies, though. After baking, the results will be sent back to Earth for safety testing. If successful, this will be the first oven to bake food in space.
“I believe…that will be game-changing for both science and astronauts, ”food technology researcher Maeena Naman Shafiee told Scientific American.
One of the main driving forces behind this project has been NASA's 2018 research into the effects of " confinement(封闭)and isolation(隔离)”. Unlike on the International Space Station(ISS), astronauts traveling out of Earth's orbit may not be able to speak to their loved ones on future missions, which could lead to negative feelings.
It's hoped that the chance to bake and sense familiar smells can bring joy to crews(宇航人员).
“Is the ISS going to smell like fresh-baked cookies? We don't know, ”said NanoRacks' communications manager Abby Dickes. “But that's a feeling we all know and love…that will make someone feel at home.”
Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel. Astronauts have already grown plants aboard the ISS.
With commercial(商业的)space travel now being planned, who knows what other developments may surprise us in the future

【3】D
【解析】
太空旅行听起来让人兴奋,但是宇航员们必须忍受那些不好吃的食物。太空中的食物要经过脱水或者预煮熟,然后储存,因此它们尝起来就没那么新鲜。现在,新的科技带来了改变,一个特殊设计的烤箱将被送到太空,这样宇航员在太空就能品尝到新鲜出炉的饼干。这在太空史上将是重要的一步。
【1】细节理解题。根据“Far from the common vacuum-packed(真空包装的)meals, astronauts may get to enjoy freshly baked cookies before the end of 2019.”可知这项新科技能够让宇航员在太空吃到新鲜出炉的饼干。故选B。
【2】细节理解题。根据“For one thing, there's the risk of a fire. Engineers also have to overcome the challenge of microgravity, which prevents heat from circling inside ovens the same way it does on Earth.”可知在太空做饼干其中一个风险就是火,因为微重力的关系,火并不能像在地球上一样加热食物。故选D。
【3】推理判断题。根据“Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel.”可知在太空上制作饼干是非常重要的一步,它给宇航员在艰难、不熟悉的太空环境中提供一个小小的舒适感,因此可推断饼干计划的主要目的就是让宇航员在太空更加舒适。故选D。

【题目】 When throwing away rubbish, do you know which bin it should go in? Have you ever noticed the differently-colored rubbish bins on the street? Some of you might not be able to answer the questions. However, it's actually quite important to know how to sort your rubbish. Not knowing how to sort rubbish can make it harder to save energy and protect the environment. If you don't sort your rubbish, all of it will be buried (埋) together. It can take up large areas of ground that could have been used for planting trees. Shanghai is the first city to put rubbish-sorting into practice in China.
Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable (可回收的), harmful and dry. "Wet" rubbish is also known as "household" rubbish. It is what people produce every day after they eat or drink. "It is the thing you don't want but pigs can eat", Guangzhou Daily explained. Paper, metal, glass and other things that can be reused are recyclable rubbish.
Harmful rubbish includes things like medicine, batteries and so on. Finally, any rubbish that is not wet, recyclable or harmful will go in the dry rubbish bin. Many other Chinese cities, including Changsha, plan to use this method to sort their rubbish. Now that you know this, perhaps you can do your part in protecting the environment.

A.look more beautiful
