书面表达

为了帮助中学生健康成长,某中学英文报开辟了“HEART-TO-HEART”专栏。假设你是该栏目的编辑Jamie,收到一封署名为Worried的求助信。信中该同学向你诉说了自己的困扰:近日容易发脾气,使正常的学习和生活受到了影响。请用英文给该同学写一封回信。

内容要点如下:

1).表示理解并给予安慰;

2).提出建议并说明理由。

注意:

1).词数120左右;

2).信中不能出现与本人相关的信息;

3).信的开头与结尾已为你拟好,不计入总词数。

参考词汇:temper n. 脾气,情绪

Hi Worried,

    I'm sorry to know that you're having such a bad time at the moment. ……

Yours,

Jamie

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    It's normal to wake briefly during the night. {#blank#}1{#/blank#}But if you're waking up during the night and having trouble falling back asleep, the following tips may help.

    Stay out of your head. The key to getting back to sleep is continuing to prepare your body for sleep, so remain in bed in a relaxed position. Hard as it may be, try not to stress over the fact that you're awake , because that very stress and anxiety encourage your body to stay awake. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#} If you are finding it hard to fall back asleep, try a relaxation technique such as visualization, deep breathing, or meditation, which can be done without even getting out of bed. Remind yourself that although they're not a replacement for sleep, rest and relaxation still help refresh your body.

    Do a quiet, non-stimulating activity. If you've been awake for more than 15 minutes, try getting out of bed and doing a quiet, non-stimulating activity, such as reading a book. Keep the lights dim so as not to think that it's time to wake up. {#blank#}4{#/blank#} A light snack might help relax you, but be careful not to eat so much that your body begins to expect a meal at that time of the day.

    {#blank#}5{#/blank#} If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone worrying about it until the next day when you are fresh and it will be easier to resolve.

A. Make relaxation your goal, not sleep.

B. Put off worries and troubles.

C. Use a flashlight to go to the bathroom at night.

D. In fact, a good sleeper won't even remember it.

E. Also avoid screens of any kind—computers, TVs, cell phones, iPads,

F. You'll be much more productive and creative after a good night's sleep.

G. A good way to stay out of your head is to focus on the feeling in your body.

如图所示,AB、CD为一圆的两条直径,且互相垂直,O点为圆心。空间存在一未知静电场,方向与圆周所在平面平行。现有一电子,在电场力作用下(重力不计),先从A点运动至C点,动能减少了W;又从C点运动至B点,动能增加了W,那么关于此空间存在的静电场可能是
A.方向垂直于AB并由C指向O的匀强电场
B.方向垂直于AB并由O指向C的匀强电场
C.位于O点的正点电荷形成的电场
D.位于D点的正点电荷形成的电场
