You may have grown up living with sisters and brothers, or this may be your first time sharing your living space with someone else. Having a roommate surely has its challenges.{#blank#}1{#/blank#} Follow these tips to make sure you and your roommate keep things pleasant and supportive throughout the year.

    Be clear from the beginning.

    Maybe you hate it when someone interrupts you when you are sleeping every morning.{#blank#}2{#/blank#}, Let your roommate know about your preferences. It's not fair to expect him or her to pick up on them right away, and communicating what you need is one of the best ways to get rid of problems before they become problems.

    Respect your roommate's things.

    This may seem simple，but it's probably one of the biggest reasons why roommates experience conflicts. Don't you think he'll mind if you borrow his shoes for a quick soccer game for all you know, you just stepped over an uncrossable line.{#blank#}3{#/blank#}

    Be open to change.

    You should expect to learn and grow and change during your time at school. And the same should happen to your roommate, if all goes well.{#blank#}4{#/blank#}. Be comfortable addressing things that unexpectedly come up, setting new rules, and being flexible to your changing environment.

    {#blank#}5{#/blank#}

    Treat your roommate like you'd like to be treated. No matter what your relationship is at the end of the year, you can take comfort knowing you acted like an adult and treated your roommate with respect.

A. Don't borrow, use, or lake anything without getting permission first.

    Low-Cost Gifts for Mother's Day

    Gift No. 1

    Offer to be your mother's health friend. Promise to be there for any and all doctor's visits whether a disease or a regular medical check -up. Most mothers always say no need, another set of eyes and ears is always a good idea at a doctor's visit. The best part? This one is free.

    Gift No. 2

    Help your mother organize al1 of her medical records, which include the test results and medical information. Put them all in one place. Be sure to make a list of all of her medicines and what times she takes them. “Having all this information in one place could end up saving your mother's life,” Dr. Marie Savard said.

    Gift No. 3

    Enough sleep is connected to general health conditions. “Buy your mother cotton sheets and comfortable pillows to encourage better sleep.” Savard said. “We know that good sleep is very important to our health.”

    Gift No. 4

    Some gift companies such as Presents for Purpose allow you to pay it forward this Mother's Day by picking gifts in which 10 percent of the price you pay goes to a charity (慈善机构).Gift givers can choose from a wide variety of useful but inexpensive things many of which are “green”—and then choose a meaningful charity from a list. When your mother gets the gift, she will be told that she has helped the chosen charity.

    Winter is a really fun time of the year—it's great to have snowball fights and build snowmen. {#blank#}1{#/blank#} When it's cold outside and you're not prepared, you can feel uncomfortable. Lucky for you, learning how to stay safe is not difficult.

    {#blank#}2{#/blank#}Wearing thick clothes is the best way to stay warm in the cold. Depending on where you live and how cold it is, some kids may need more clothes, some less.

    Take that hat. You maybe wear a large overcoat and ready to go, but are you forgetting something?{#blank#}3{#/blank#}You'll stay much warmer with a hat than without one—tons of body heat escapes right from your head.

    Drink up. Sounds like advice for hot weather, not cold weather, right?{#blank#}4{#/blank#}When you're outside in the cold and breathing hard, your body loses a lot of water through your breath. And the best way to get that water back is to drink up!

    Take it easy. Sometimes if you're out having fun, it's easy to forget to pay attention to your body. But if your body temperature drops even 4 or 5 degrees while you're outside, it can make you feel terrible.{#blank#}5{#/blank#}And if you ever feel weak, those are signs that you have to take it easy indoors for a while.

How to Sleep Better

    If you're having trouble getting good sleep through the night (turning, waking up more than once, for example), this text will tell you what you can do to ensure a peaceful night's sleep.

    ⒈Get up on time. Changing your sleeping time by more than an hour can severely disturb (干扰) your sleep quality. {#blank#}1{#/blank#} For example, if you normally wake up at 6 am on weekdays to get to work, you might go to bed around 10 pm, because that's when you start to feel sleepy, and it's also a good time to ensure 8 hours of sleep. If, on the weekend, you sleep until 9 am, you probably won't be able to fall asleep that night until 1 am.

    ⒉{#blank#}2{#/blank#} Wait at least three hours after dinner before going to sleep. Digestion(消化) slows down while asleep, and a full stomach may interrupt(打搅) sleep. Similarly, you should avoid going to bed on an empty stomach, as a completely empty stomach may equally disturb your sleeping patterns(模式).

    ⒊{#blank#}3{#/blank#} Exposure(暴露) to light during the time when you're supposed to be sleeping can disrupt(扰乱) your body's internal clock. Turn your light off, or use a very dim night light. {#blank#}4{#/blank#}They include windows, LED clocks, computer lights and cable boxes.

    ⒋Change your sleeping position. You may think that it's impossible to control what position you sleep in since you don't fully understand what you are doing, but it is possible and it can make a big difference. {#blank#}5{#/blank#}

A. Try to avoid all sources of light.

B. Keep the room as dark as possible.

C. Make note of unusual circumstances (状况).

D. Be mindful of what you eat or drink before bed.

E. Sleep is considered to be adequate only when there is no daytime sleepiness.

F. In other words, sudden change of sleeping time will affect your “biological(生物的) clock”.

G. If you wake up in the middle of the night, make an effort to have a comfortable position.

    Our cities have never been denser, taller, or busier than they are now, and with that, comes the constant battle for land. But if we look at aerial images of any city center, we can quickly spot plenty of unused space — the rooftops.

    So what can we use this precious resource for? In a growing number of high-density cities, some of it is dedicated to recreation — everything from bars and pools, to soccer pitches and running tracks can now be found atop skyscrapers. But when a rooftop offers access to sunlight, there are two more obvious candidates for its use - agriculture and solar power.

    Green roofs have been growing in popularity for more than a decade, and in some cases, growing in scale too. Green roofs can provide a habitat for birds and insects in an otherwise hostile environment.

    Cities can be several degrees warmer than the surrounding countryside. Green roofs come with the added benefit of mitigating the dreaded urban heat island effect. Trees and green spaces can absorb shortwave radiation, and use it to evaporate water from their leaves — a kind of 'double cooling' effect.

    With food security and urban nutrition ever-higher on the agenda for the United Nations, there's also a worldwide movement of using green roofs for hyper-local food production. In regions with suitable climates, hundreds of different vegetables, fruits, and salad leaves can be grown on rooftops.

    But what about solar power? With so many cities now stopping using fossil fuels, and the costs of solar panels dropping dramatically, PV systems have become the 'go to' option for generating distributed power in built-up areas. And, even with standard commercial panels, the energy gains are dramatic. It is estimated that rooftop PV systems could generate almost 40% of electricity demands nationwide.

    There's no doubt that in both cases, a network of 'productive rooftops' could benefit the local community by supplying a portion of a necessary resource — either food or electricity — while also reducing their environmental burden. But is one better than the other?

    This was the question posed by researchers from MIT and the University of Lisbon in a recent paper in the journal Cities. Focusing on the rooftops of a mixed-use neighborhood in Lisbon, they carried out a Cost-Benefit Analysis. Starting with existing data on everything from installation costs and resources used, to carbon footprint and yield, they modelled the impact that each installation would have on the local community over a period of 50 years.

    And by looking at it that way, they concluded that for Lisbon, the use of rooftops for food production could yield significantly higher local value than solar PV energy generation. Of course, this is very site-specific. There is no one-size-fits-all solution to make cities more sustainable, and anyone who tells you otherwise is massively over-simplifying a complex issue. Now, all I hope is that some of those decision makers start using it.
