A good friend not only likes to hang with you and have {#blank#}1{#/blank#}good time, but thinks about you and wishes good things for you when you're apart. A good Friend may not talk to you every day or even every week, {#blank#}2{#/blank#}can come up in a matter of minutes. A good friend will come to help you, even when you haven't talked to him in weeks. Time doesn't lessen a good friend's relationship with you.

    Beth is a friend of{#blank#}3{#/blank#} (I), I can for weeks without{#blank#}4{#/blank#} (talk) to her but then drop anything in minutes because {#blank#}5{#/blank#}her. She has no problem giving me some of her {#blank#}6{#/blank#} (suggest) either, Last week. I{#blank#}7{#/blank#} (buy) a pair of jeans which wasn't{#blank#}8{#/blank#}(exact) right for me. Some of my friend laugh at me. Beth would give a bees opinion, rather than leaving me hanging with my big jeans. She advised me{#blank#}9{#/blank#} (wear) this mini skirt instead because it made me look pretty.

    I believe that good friends also{#blank#}10{#/blank#} (be) the most honest with you, instead of looking down on you, showing off themselves or ignoring you. Beth is a friend like that. I feel so lucky to have such a friend.

    China reached a milestone in space exploration on January 3, 2019. Chang'e-4 {#blank#}1{#/blank#} (successful) landed on the far side of the moon's surface.

    This is the first time in history{#blank#}2{#/blank#} any country has performed a soft landing on the back of the moon. It is also a huge win for Chinese scientists who have been planning out this work for {#blank#}3{#/blank#} (year).

    Shortly after the lander's arrival, it sent back a photo of the Yutu rover (月球车) {#blank#}4{#/blank#} (roll) slowly across the moon's dusty surface. As{#blank#}5{#/blank#} (expect), the lander will conduct a number of challenging tasks. It will observe the low-gravity environment and explore {#blank#}6{#/blank#} there is water or other resources. Later, soil samples{#blank#}7{#/blank#} (collect) and returned to the earth. Scientists believe that the back of the moon is {#blank#}8{#/blank#} (ancient) than the front, so the soil age is valuable for studying the early history of the moon.

    Since the far side of the moon is quiet and free {#blank#}9{#/blank#} electromagnetic interference (干扰) from the earth, it's a perfect place to research the space environment. Everything {#blank#}10{#/blank#} (appear) to be working smoothly, and we can expect plenty of moon news out of China in the near future.

    People are being lured(引诱) onto Facebook with the promise of a fun, free service, {#blank#}1{#/blank#} realizing that they're paying for it by giving up plenty of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send{#blank#}2{#/blank#} (target) messages.

    Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea {#blank#}3{#/blank#} they're paying for Facebook, because people don't really know what their personal details are worth.

    The biggest problem, however, is that the company keeps changing the rules.  Early on, you could keep everything private. That was the great thing about Facebook -- you could create your own little private network. Last year, the company changed its privacy rules {#blank#}4{#/blank#} many things -- your city, your photo, your friends' names -- were set, by default(默认), to be shared with everyone on the Internet.

    According to Facebook's vice president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a “{#blank#}5{#/blank#} (satisfying) experience.”

    Some critics think this is more about Facebook looking to make more money. Its original business model, {#blank#}6{#/blank#} involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they are connecting with their friends online?

    So far the privacy issue {#blank#}7{#/blank#} (land) Facebook in hot water in Washington. In April, Senator Charles Schumer called on Facebook to change its privacy policy.  He also urged the Commission to set regulations for social-networking sites.

    I suspect that whatever Facebook has done {#blank#}8{#/blank#} (invade) our privacy is only the beginning, which is why I'm considering {#blank#}9{#/blank#} (cancel) my account.  Facebook is a handy site, but I'm upset by the idea that {#blank#}10{#/blank#} information is in the hands of people I don't trust. That is too high a price to pay.

    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.
