I was on my way home with a friend yesterday {#blank#}1{#/blank#} I found a mobile phone by the roadside. After picking it up, I suggested that we go to the house in front of which we found the mobile phone. And we did so. I {#blank#}2{#/blank#} (knock) at the door and two young men answered. Neither of them had lost {#blank#}3{#/blank#}(they) phones, but as I referred to some names on the contact list(通讯录), one of them said he also had those {#blank#}4{#/blank#}(name) and that it must be the phone of one{#blank#}5{#/blank#}their friends. Then, he took the phone and said how wonderful it was that I took the time{#blank#}6{#/blank#}(find) the owner. Afterwards, I left without {#blank#}7{#/blank#}(leave) my name or address. I never considered keeping the phone. Instead, I immediately tried to find {#blank#}8{#/blank#} owner. And I believed that was {#blank#}9{#/blank#}(exact) what I would want someone to do if I lost my phone. It couldn't have been {#blank#}10{#/blank#} (good).

Dear Li Kang,

    I'm exciting to tell you about the American school system. Secondary school in the US usually covered seven years, grades six to twelve. At the end of twelfth grade, American student receive the high school diploma. Students need a high school diploma if they want to go to the college.

    The school year is dividing into two semesters, the first of that is September through December, and the second January through May. We have a long summer vacation! We start school in 7: 50 am and we finish at 3 pm.

    I take part in many amazed after­school activities—I play football, basketball, volleyball, table tennis and I went to theater club.

    Will you tell me something about your summer vacation and the Chinese school system in your next letter?

    Looking forward hearing from you soon.

    Rob Marshall

    You may not have noticed it before, but many people often sit with a hunched (驼背的) back when they are in a difficult situation, such as trying hard {#blank#}1{#/blank#} (solve) a math problem. But there's a reason for this: this body position helps to reduce pressure.

     However, according to Erik Peper, a health professor at San Francisco State University, poor posture (姿势) may make our brains work not as well as they {#blank#}2{#/blank#} (normal) do.

    Peper and a team of researchers {#blank#}3{#/blank#} (study) 125 students' performance in a math test and their different postures. The team found that good posture—for example sitting up straight—could help people perform better {#blank#}4{#/blank#} bad posture when they feel stressed.

    Another professor Richard Harvey further explained in Science Daily that sitting with bad posture might make us feel more {#blank#}5{#/blank#} (comfort), but it actually increases our pressure levels.

    So the next time you have to take a test, try sitting upright and taking a deep {#blank#}6{#/blank#} (breathe). If Peper's study is correct, this small change may have {#blank#}7{#/blank#} great influence on you.

    There are many things {#blank#}8{#/blank#} lead to poor posture. The good news {#blank#}9{#/blank#} (be) that posture can be improved at any age by {#blank#}10{#/blank#} (make) just a few simple corrections in the way one stands, sits and moves.

What does "barking (犬吠) up the wrong tree" mean? In this article, let's learn the {#blank#}1{#/blank#} (express).

The phrase "barking up the wrong tree" means {#blank#}2{#/blank#} (follow) a mistaken plan of action. The phrase comes from the old hunting (捕措) practice in which dogs would bark to show they have made other animals up trees unable {#blank#}3{#/blank#} (run) away. Sometimes the dogs were mistaken, and the animals had {#blank#}4{#/blank#} (actual) run away. When this happened, the dogs were barking up the wrong tree.

This phrase first began appearing in {#blank#}5{#/blank#} (write) works after the 1820s, and was later widely used by western writers. It was used to describe anyone {#blank#}6{#/blank#} was following a wrong lead. Below is an example of how to use the phrase. Recently {#blank#}7{#/blank#} friend of mine needed a large amount of money {#blank#}8{#/blank#} his new business idea. So he went to an event to meet possible investors (投资者). However, the people he met {#blank#}9{#/blank#} (be) those also looking for money. Then we can say that he was barking up the wrong tree!

When using the phrase, avoid {#blank#}10{#/blank#} (mistake) in spelling. For example, don't write it as "barking up in the wrong tree".
