不要让窗户像这样一直破着。

我昨天让人修了我的自行车。

玛丽的手表在前几天被人偷了。

我提高了嗓门儿以便让别人听到我的话。

到学校时，我们看见门锁着。

小偷被带了进来，双手被绑在背后。

    Ottawa is the capital of Canada. It is the second largest city in Ontario and the fourth largest city in the country.

    The Centre Block is the main building on Parliament Hill (国会山). It is also the location of several ceremonial spaces, such as the Hall of Honor and the Memorial Chamber. The present Centre Block is the second iteration of the building, after the first was destroyed by fire in 1916, and it is one of the most recognizable buildings in Canada.

    Downtown Ottawa is the commercial and economic centre of the city. Most of the buildings are office towers. While most of Ottawa's high tech industry is based elsewhere, it has a significant presence in the downtown core. The downtown also contains a number of apartments, hotels, and the older single family homes and townhouses along its edges.

    The National Gallery of Canada is one of Canada's premier art galleries. The Gallery has a large and varied collection of paintings, drawings, sculpture and photographs. Although its focus is on Canadian art, it also holds works by some noted American and European artists.

    The Rideau Canal is the oldest continuously operated canal system in North America. At the very beginning, the purpose of the Rideau Canal was military, as it was intended to provide a secure supply and communication route between Montreal and the British naval base in Kingston. It remains in use today primarily for pleasure boating, with most of its original structures undamaged. The locks on the system open for navigation in mid­May and close in mid­October.

    You'll be likely to become angry if you don't get a good night's sleep, a new paper reports. Cutting a few hours of sleep out of your schedule isn't as good an idea as it may appear. Researchers at the Iowa State University report that missing sleep will make you angrier, leaving you ill­equipped to deal with uneasy situations. This is one of the first studies to provide evidence that sleep loss causes anger.

    The link between lack (短缺) of sleep and negative moods (anger included) has been proved in past research, but the problem is that we know that the two come together, but not that whether one causes the other. In the current study, Krizan and co­author Garrett Hisler, an ISU doctoral student, deal with this question.

    Under the study, volunteers were divided into two groups. The control group followed their normal sleep routine, while the experimental group cut two to four hours of sleep each night for two nights. On average, the control group got almost seven hours of sleep a night, while the experimental group got about four and a half hours each night.

    In order to measure anger, they had volunteers visit the lab before and after the sleep manipulation (操纵). All the while, they were asked to listen to some unpleasant brown and white noise. Krizan says the purpose was to create uncomfortable conditions.

    "In general, anger was much higher for those whose sleep was restricted (限制)，" Krizan said. "We manipulated how unpleasant the noise was during the task. As expected, volunteers reported more anger when the noise was more unpleasant. When sleep was restricted, people reported even more anger, regardless of the noise."

    Sleep loss is known to increase negative moods, such as anxiety and sadness, and decrease positive moods, such as happiness and excitement. However, the team says they found that sleep loss uniquely affected anger.

    As a student in my final year of high school, I am very concerned about college. I spend most days thinking about the 1, hoping that I'm on the right path.

    I'm interested in a career in 2, so I decided to volunteer for service at the local hospital. I thought it would be the best of both worlds: 3 people while getting valuable on­the­job experience! So I went to the business office. 4, the hospital director was quite willing to let me help out, and he said I could 5 that summer as soon as I finished my finals. I accepted his 6 immediately, thinking to myself that here lay all the 7 I could ever want!

    Soon enough, I 8 for my first day at the 9. The director gave me a brief tour of different departments (科室) 10 we stopped right in front of the maternity ward (产科病房). "This is where you're going to 11," he said. I was overwhelmed (受不了的) by the sounds. Women shouted and newborns 12. I got nervous and wondered if I had been in a hurry when I 13 to go for such a 14 job.

    My 15 must have shown clearly on my face because the director said, "Don't worry. You are going to help in the nursery." 16 that, we walked down a hallway filled with balloons, beautiful flowers and into the 17 room I've ever seen. The soft colors provided a quiet backdrop to the sleeping babies. The nurse in charge of the nursery 18me, thanked me for19, and asked me to start putting some baby things away in the drawers. The director gave me a 20 look, which I returned with a quiet nod. I got right to work.

    Winter in Quebec, Canada is very different from that in England. When I first arrived, I was (slight) worried about the winter. I couldn't imagine it would be like to have 3 metres of snow and what on earth I was going to do when the weather was so bad. However, here, life goes on as usual. Trains and buses continue, and people socialise and even better. number of new sports take over.

    For me, skiing means downhill skiing, in ski resorts (度假胜地), with ski lifts taking you up the mountain. Before (arrive), I did not know there were in fact different (type) of skiing. Imagine a sunny but cold day, and you have taken a chairlift to the top of a mountain (cover) in snow. An hour seems like a few minutes, as you carve your way down a run to the bottom, and then do it all again. It is my new favourite sport.

    Ice skating on a frozen (结冰的) lake is another (excite) sport for me. Once I could hardly stand on a pair of ice skates, but now I am able to make laps (圈) of the 3 km route on the lake,   is frozen during January and February.

    Indeed having 3 metres of snow was a bit frightening. School (cancel) once because of a big snowstorm, but I was busy enjoying all these cool sports that winter finished too soon!
