山东省烟台市第二中学2018-2019学年高一上学期英语冬学竞赛试卷(音频暂未更新)
Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.
One idea is that sleep helps us strengthen new memories. We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.
Support is growing for a theory that sleep evolved(进化) so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.
Now we have the most direct evidence yet that he is right. The synapses (神经突触)in the mice taken at the end of a period of sleep were 18 percent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping .
If Tononi's theory is right, it would explain why, when we miss a night's sleep, we find it harder the next day to concentrate and learn new information--our brains may have smaller room for new experiences.
Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. “You keep what matters,”Tononi says.
A. We should also try to sleep well the night before.
B. It's as if the brain is preserving(保存) its most important memories.
C. Similarly, when people go for a few days without sleeping, they get sick.
D. The processes take place to stop our brains becoming loaded(装载) with memories.
E. That's why students do better in tests if they get a chance to sleep after learning.
F. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.
G. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.
Home on the Way
People need homes: Children assume their parents' place as home; boarders call school “home” on weekdays; married couples work together to build new homes; and travelers…have no place to call “home”, at least for a few nights.{#blank#}1{#/blank#} Don't they have the right to a home? Of course they do.
Some regular travelers take their own belongings like bed sheets, pillowcases and family photos to make them feel like home no matter where they are; some stay for long periods in the same hotel and as a result become very familiar with the service and attendants; {#blank#}2{#/blank#} Furthermore, driving a camping car during one's travel and sleeping in the vehicle at night is just like home.
And how about keeping relationships while in transit? {#blank#}3{#/blank#}; some send letters and postcards, or even photos;others may just call and say hi, just to let their friends know that they're still alive and well. People find ways to keep in touch. Making friends on the way helps travelers feel more or less at home. {#blank#}4{#/blank#}
Nowadays, fewer people are working in their local towns, so how do they develop a sense of belonging? Whenever we step out of our local boundaries, there is always another “home” waiting to be found. {#blank#}5{#/blank#} we can make the place we stay “home”.
A. Hostels provide a clean and safe place to stay while you are traveling the world. B. others may simply put some flowers by the hotel window to make things more homely C.

Developing and maintaining healthy friendships involves give-and-take. {#blank#}1{#/blank#}Expressing your feelings of affection and gratitude towards your friends is a powerful way to reinforce the connections you share with them. It is equally crucial for you to embody the qualities of a supportive and considerate friend as it is to be surrounded by individuals who embody these traits. By acknowledging and valuing the presence and contributions of your friends in your life, you not only nurture your relationships but also create an environment of mutual respect and understanding. This reciprocal appreciation can lead to deeper, more meaningful friendships that stand the test of time.
To nurture your friendships:
Be kind. This most-basic behavior remains the core of successful relationships.{#blank#}2{#/blank#} Every act of kindness and every expression of gratitude are deposits into this account, while criticism and negativity draw down the account.
Be a good listener.{#blank#}3{#/blank#} Let the other person know you are paying close attention through eye contact, body language and occasional brief comments such as, "That sounds fun." When friends share details of hard times or difficult experiences, be empathetic, but don't give advice unless your friends ask for it.
Open up. Build intimacy with your friends by opening up about yourself. Being willing to disclose personal experiences and concerns shows that your friend holds a special place in your life, and it may deepen your connection.
{#blank#}4{#/blank#}Being responsible, reliable and dependable is key to forming strong friendships. You're your engagements and arrive on time. Follow through on commitments you've made to your friends. When your friends share confidential information, keep it private.
Make yourself available. {#blank#}5{#/blank#} Make an effort to see new friends regularly, and to check in with them in between meet ups. You may feel awkward the first few times you talk on the phone or get together, but this feeling is likely to pass as you get more comfortable with each other.
