                                                                                            爱，有时是一种错误
         ①这样开始新的一天，已经六年了，只是今天，略有不同。
         ②在朝霞甩下的水袖里，忽地有了一片晃眼的色彩，温柔地旋开细嫩的花瓣，在秋天里微微地颤动，草地一下子灿烂起来。
         ③父亲催促我快些，我也只好收回眼神。奔向学校。
         ④一天很快地在挂念里过去了，再见到它们时，太阳已在遥远的地方等待落下，而那些花儿，褪尽了初绽的青涩，在夕阳里灼灼地期盼着。高大的棕榈投下灰暗的影子，而花儿们却如同太阳一般抵抗黑暗，在影子里依旧晃眼。
        ⑤父亲笑着问我：“喜欢么？太阳花很漂亮呢！”
        ⑥太阳花？怪不得让人那样喜欢，多可爱啊。
        ⑦很快的，我的窗台上也有了一盆太阳花，茂密的叶子托着玲珑的花蕾，隔着玻璃窗，冲着我甜甜地笑。相信过不了多久，我的窗台就会如同清晨一样灿烂，而我将拥有一片属于自己的彩霞，每天，每夜。我细心地浇水，呵护，太阳花在满怀的期待里成长。
        ⑧时间就这样一天一天地过去。转眼临近期末考，以学习为主的我并没有发现遗忘了什么。
        ⑨终于考完了，我扔下书包，亲近久违的蓝天，阔别的草地，可心里总有块地方空着，似乎是我忘记了什么。
        ⑩我开始清理房间，准备度一个快乐的寒假，拉开窗帘的那一刹那，我像是忽然清醒起来，窗台上本该有一片彩霞，我的太阳花！可是，一切都不一样了，枯黄的枝条在花盆里盘旋，有的已经伸出盆外，唯一的一个花蕾垂着凋零的脑袋，显然是不会不再开放了。
       ⑪依旧是秋天，依旧是夕阳西下，那给我灿烂的太阳花，今日却分外凄凉。它安静地伏在窗台上，定格在枯萎的瞬间，世界从此与它不再相关。我有了很深重的负罪感，是因为我的爱，它才来到我家，而又是因为我的疏忽，它才过早地走了。这一切，都是我犯下的错误，不可挽回了。轻轻地把太阳花埋在地里，我走了。身后是去年同它一起开放的同伴，今天它们的绚丽，对我来讲，似乎是批判，我的爱，错了。
        ⑫转身的瞬间，我想起好多过去的事，好些东西都像太阳花一样可惜，我爱它们，便固执地将它们放进自己的空间，可到了最后，我总是不能很好地继续爱下去，以至于对我来说触手难及，而别人也无法得到。
       ⑬其实很多时候，爱，是一种错误。

阅读下列短文，从每题所给的四个选项（A、B、C和D）中选出最佳选项。
   Bored with your life? Dreaming of something different? When I feel like that I look up and wonder what life would be like 400km above my head. That's where the International Space Station orbits the Earth, with six astronauts living and working on board, for months at a time.
How do they sleep? They spend the night floating in a sleeping bag inside a small cubicle on the ceiling. American astronaut Sunita Williams explains: "It's like a little phone booth but it's pretty comfy and it doesn't matter if I turn over and sleep upside down. I don't have any sensation in my head that tells me I'm upside down."
Brushing your teeth in a place where you can't have a tap or a sink can be a challenge. Can you imagine the mess that running water would make in zero gravity? Canadian astronaut Chris Hadfield uses a straw to put a big blob of water from a sealed bag onto an ordinary toothbrush and adds a little toothpaste - which he has to swallow when he's done.
Daily exercise is essential. The lack of gravity makes bones more brittle and muscles lose strength – so astronauts are encouraged to work out for at least two hours a day.
The role of astronauts in the International Space Station is to act as lab technicians for scientists back on Earth. So they spend their time maintaining their environment and performing and monitoring experiments in a confined space about the size of a Boeing 747. Almost every task is carefully planned by mission control - although most astronauts spend their first days losing stuff until they get used to sticking everything they use to the walls with Velcro, duct tape or clips.
One of their most valued perks is the view from "the office", dominated by that gigantic blue ball down there, sitting in the darkness of space. Wow! Absolutely breathtaking!
