    When high temperatures are around the country, some things also go up. Here are four things expected to rise along with our desire to stay indoors and best the heat.

    ①Sales of goods that keep you cool.

    Malls are high on the list of places where people often go for free air conditioning outside home in summer.{#blank#}1{#/blank#}Goods related to keeping cool, like air conditioners, fans or sun care items, are very popular.

    ②{#blank#}2{#/blank#}

    Pests like stink bugs(椿象) grow fast during summer heat waves, and many agriculture experts are expecting a repeat of last year's incident that harmed fruit and crops, particularly on the East Coast.

    ③Energy bills

    {#blank#}3{#/blank#}With all those air conditioners and fans working, it makes sense that energy bills will be higher than average.{#blank#}4{#/blank#} “Not only are people going to have extremely high energy bills for July, it will also put increased stress on power plants, and we're going to see more air pollution because of it,” says Angela Fritz.

    ④Violence

    Heat waves may cause violence, right?

    Not necessarily, says Richard Larrick, a researcher. He took a unique look at the relationship between violence and heat through baseball. Larrick and his research team examined 57,294 Major League Baseball games taking place between 1952 and 2017 and found that while heat may increase violence, there always has to be a motive. “{#blank#}5{#/blank#}Instead, heat affects a specific form of violence,” he said.

A. Air pollution

B. Pest population

C. Rising heat is the expected response in any summer

D. Heat does not directly lend to more violence in general

E. More and more people are worried about their expenses

F. As more energy is used, air-quality problems may occur

G. So it's not a surprise that some sales jump during heat waves.

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

    Schedule yearly exams. {#blank#}1{#/blank#}Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eye- glasses.

    Protect against UV rays . Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. {#blank#}3{#/blank#}Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#}As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight.

    What do the world's most successful people all have in common? The researchers found that high achievers like Robert Moses turn out to be all alike:

    Busy！Busy!

    {#blank#}1{#/blank#} in a study of general managers in industry, John Kotter reported that many of them worked 60 to 65 hours per week-which translates into at least six 10-hour days. The ability and willingness to work difficult and tiring hours has characterized many powerful figures. Energy and strength provide many advantages to those seeking to build power.

    {#blank#}2{#/blank#}

    The difference between successful people and very successful people is that very successful people say “no” to almost everything. And that's what gives them the time to accomplish so much. {#blank#}3{#/blank#}. And focus means saying “no” to a lot of distractions（分散力）.

    Know what you are

    Ignore weakness and keep improving your strengths. Don't waste time exploring skill areas where you have little competence. Instead, focus on-and build on-your strengths. {#blank#}4{#/blank#}

    {#blank#}5{#/blank#} Wiseman created a “luck school” to test these ideas-and it was a success. In total, 80 percent of people who attended luck school said that their luck bad increased. On average, these people reported that their luck had risen by more than 40 percent.

    {#blank#}4{#/blank#} People often won't take "No" for an answer. If you say "No" to someone，they may give you various reasons to try and change your mind. Stay determined for your decision and do not give in easily.
