If you'd love to be more eco-friendly but don't know where to begin, start with a few small changes.  {#blank#}1{#/blank#}

    Adjust your thermostat（恒温器）to save on heating and cooling costs.  {#blank#}2{#/blank#}In summer, set your thermostat to 78 ℉when you're at home and raise the temperature when you're away. In winter, turn your thermostat to 68 ℉ and lower it by 5°-10° when you're sleeping or out of your house. To stay warm in winter, put on a sweater or another layer instead of turning up the thermostat.

    Turn off lights and unplug power strips that you're not using. {#blank#}3{#/blank#}Some devices can still use energy even when they're turned off. So, turn off the power strips at night to completely cut off energy use. If you need to leave your computer or TV on, try setting it to sleep mode.

    Make your taps and toilets low-flow. Cut back on water waste by installing flow restrictor(节流装置) inside your taps and installing a low-flow shower head in your bathroom. This can save 3 to 4 gallons of water for every minute. If you're replacing a toilet, look for a low-flow one to save thousands of gallons of water a year.  {#blank#}4{#/blank#}

    {#blank#}5{#/blank#} Adjust your washing machine to use cold water instead of warm. Since more energy is spent drying the clothes, skip the machine and hang your washed clothes on a clothesline. If you don't have space for a clothesline or can't hang clothes outside, set up a clothes drying rack that you can use inside. Try running your clothes through an extra spin cycle to remove even more water from the clothes. This will make them dry quicker.

    Understanding body language can lead to closer relationships. Noticing the signals that people send out with their body language and being able to effectively read them is a very useful skill.

    Watch for crying. Usually crying is considered a sign of sadness, but crying can also be an expression of happiness. {#blank#}1{#/blank#} Thus, when judging crying, you'll need to look for other signals to determine the real meaning of the crying.

    Look for signs of anger. Signs of anger include v-shaped eyebrows (眉毛), and wide eyes.{#blank#}2{#/blank#} Arms tightly crossed over the other is a common sign that the person is angry and is closing himself off to you.

    {#blank#}3{#/blank#} Studies have found that when people are engaged in an interesting conversation, their eyes remain focused on their partner's face about 80% of the time.

    Look for expressions of embarrassment. Embarrassment can be signaled by turning the eyes or head away, and forcing smiles. If someone looks down at the floor a lot, they are probably shy, or embarrassed.{#blank#}4{#/blank#} People are often thinking and feeling unpleasant emotions when they are in the process of staring at the ground.

    Notice any sense of pride. People express pride by showing a small smile, moving their head backward, and putting their hands behind their backs.

    As a general rule, people are best at reading facial expressions, and then body movements, and, finally, personal space and touch.

    {#blank#}5{#/blank#} People are generally better at reading body movements that are pleasant rather than unpleasant. One study finds that individuals are better at accurately interpreting (领会) happiness, and excitement, compared to anger, sadness, and fear.

A. Read interest from eyes.

B. Look for signals of anxiety.

C. However, different body movements have different meanings.

D. Down-turned mouth is also a sign of being angry.

E. People also tend to look down when they are upset.

F. Crying can also come about through laughter and humor.

G. However, not all body movements are equally easy to understand.

    {#blank#}1{#/blank#}You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here's how.

    Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. {#blank#}2{#/blank#} A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

    Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.

    Make good use of your time in class. {#blank#}3{#/blank#} Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

    Study regularly. When you get home from school, go over your notes. Review the important points that your teacher has mentioned in class. If you know what your teacher is going to discuss the next day, read that material. {#blank#}4{#/blank#} If you do these things regularly, the material will become more meaningful, and you'll remember it longer.

    Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so don't be over worried.

    {#blank#}5{#/blank#} You will probably discover them after you have tried these.

A. There are other methods that might help you with your studying

B. Don't forget to set aside enough time for entertainment.

C. Take advantage of class time to listen to everything the teacher says.

D. No one can become a top student unless he or she works hard.

E. Maybe you are an average student.

F. Make full use of class time to take notes of what the teacher says in class.

G. This will help you understand the next class.

    Who hasn't wished that they were just a little smarter? Maybe you're in school and just want to get a better grade on a test. {#blank#}1{#/blank#} Here are some ways you can go about boosting your brainpower.

    Sleep is one of the easiest things to do, yet one of the ones that most of us don't do. We live in a busy age and often it seems that we don't have enough time to get everything done. So many of us sacrifice our hours of sleep to accomplish our daily tasks. {#blank#}2{#/blank#}

G. Learn something new and then teach someone else how to do it.

    Now VAR technology is fully combined with the global game of soccer and made its debut (首次亮相) at the 2018 World Cup. {#blank#}1{#/blank#}. It is actually a team who work together to review certain decisions made by the main judge by watching video replays.

    The VAR team supported the judges from a centralized video room. The operators selected and provided the best angles from the relevant broadcast cameras plus two additional offside cameras. {#blank#}2{#/blank#}. They will communicate with the judges only for clear and obvious errors or serious missed incidents. The judge can delay the restart of play at any time to communicate with the VAR team. {#blank#}3{#/blank#}, the judge would start an official review. Then they will make a decision based on the information received from the VAR team.

    {#blank#}4{#/blank#}. Some fans believe that VAR causes too many interruptions, disrupting the flow of the game. But others just want a fair match and to see the correct call no matter what. They argue disruptions already take place as angry players crowd around a judge following a controversial decision. {#blank#}5{#/blank#}.

Tips for healthy travel with children

    Children make up a small but important group of travellers. Their smaller bodies and developing immune(免疫) systems make their travel health needs important. {#blank#}1{#/blank#}.

    Vaccines(疫苗) for children

    In general, there is a higher risk for most vaccine-preventable diseases when travelling abroad. {#blank#}2{#/blank#}. If you are planning to travel, check whether your child's normal vaccine schedule needs to be changed to make sure that they are fully protected before travelling.

    Malaria(疟疾) and children

    {#blank#}3{#/blank#}. Children are particularly at risk of developing severe malaria. If you must travel with children to a malaria risk area, visit a doctor to determine if anti-malarial medication is recommended. If anti-malarial medication is allowed to take, keep them in child-proof containers and out of reach of children.

    Transportation risks

    Air travel is safe for healthy children. {#blank#}4{#/blank#}. Some airlines will not allow newborns to fly. Ear pain caused by changes in pressure during landing is more common in children than in adults. To lessen the pain, babies should bottle or breast feed. Older children can chew gum or be encouraged to swallow or yawn.

    {#blank#}5{#/blank#}

    Signs and symptoms(症状) of altitude sickness in children are often mistaken for other illnesses. A child with altitude sickness may throw up, hate to eat, or be anxious. Older children may also show headaches, or difficulty breathing.

A. High altitude sickness

B. Pack a travel health kit

C. Avoid taking children to areas with a risk of malaria

D. And these diseases tend to be more severe (严重的) in children than in adults
