【題目】 However exciting space travel sounds, astronauts must still suffer with bad food. Now, food in space has to be dehydrated(使脫水)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(貨物).Far from the common vacuum-packed(真空包裝的)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(封閉)and isolation(隔離)”. 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(宇航人員).
“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(商業(yè)的)space travel now being planned, who knows what other developments may surprise us in the future

太空旅行聽起來讓人興奮,但是宇航員們必須忍受那些不好吃的食物。太空中的食物要經(jīng)過脫水或者預(yù)煮熟,然后儲存,因此它們嘗起來就沒那么新鮮,F(xiàn)在,新的科技帶來了改變,一個特殊設(shè)計的烤箱將被送到太空,這樣宇航員在太空就能品嘗到新鮮出爐的餅干。這在太空史上將是重要的一步。
【1】細節(jié)理解題。根據(jù)“Far from the common vacuum-packed(真空包裝的)meals, astronauts may get to enjoy freshly baked cookies before the end of 2019.”可知這項新科技能夠讓宇航員在太空吃到新鮮出爐的餅干。故選B。
【2】細節(jié)理解題。根據(jù)“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.”可知在太空做餅干其中一個風(fēng)險就是火,因為微重力的關(guān)系,火并不能像在地球上一樣加熱食物。故選D。
【3】推理判斷題。根據(jù)“Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel.”可知在太空上制作餅干是非常重要的一步,它給宇航員在艱難、不熟悉的太空環(huán)境中提供一個小小的舒適感,因此可推斷餅干計劃的主要目的就是讓宇航員在太空更加舒適。故選D。

【題目】 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.
