北师大版(2019)高中英语必修三Unit 8 Green Living综合能力测试卷
Do you want to know how to live an environmentally friendly lifestyle? Here is a short list of ways that you can help protect the environment.
Prevent energy leaks (泄漏) at home.
Heating and cooling can make up to 50 percent of your energy bill each month. So you'll save money and reduce your influence on the environment.
Plant trees in your yard and community.
Everyone knows that planting trees can help the environment. Trees cool your home, reducing the energy used for cooling. Trees improve mental health. Trees reduce noise pollution.
If you use ceiling fans during hot summer days, you can create a cooling environment. A few ceiling or regular fans properly placed in your home can reduce the amount of time you spend with the air conditioning on.
Use solar energy more often.
There are lots of inexpensive solar products you can try out. For example, solar-powered lights. How about solar cell phone chargers? Additionally, there are many forms of passive solar energy that can help you take advantage of the sun.
Think about green transportation.
Just sit and think about a few environmentally friendly ways you can get from one place to another. You can walk or bike to the corner store. Walking instead of driving to a store is a great way to help the environment!
A. Trees have many good influences.
B. Use natural wind to dry your clothes.
C. There are many ways to use solar power.
D. Use ceiling fans to cool off in summer.
E. You can take a bus when going to the movie theater.
F. Turn off lights and electronic devices when you're not using them.
G. You can heat and cool your home more efficiently by fixing leaks.
The main cause of death and disability in the US
Stroke (中风) is the main cause of death and disability in the United States. Every 45 seconds, someone in America has a stroke. {#blank#}1{#/blank#} It is the nation's third leading cause of death, ranking behind diseases of the heart and all forms of cancer. The following is something more about stroke.
Definition and description of a stroke
Stroke is a type of cardiovascular disease. It affects the arteries(动脉) leading to and within the brain. A stroke occurs when a blood vessel(血管) that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. {#blank#}2{#/blank#} So stroke forms.
{#blank#}3{#/blank#}
The American Stroke Association has identified several factors (因素) that increase the risk of stroke. The more risk factors a person has, the greater the chance that he or she will have a stroke. Some of these you can't control, such as increasing age, family health history, race, and previous stroke. {#blank#}4{#/blank#} Factors resulting from lifestyle or environment can be improved with a healthcare provider's help.
Breakthroughs in treatment
{#blank#}5{#/blank#} In fact, about 600,000 people have strokes every year. For many years, there was no hope for those suffering a stroke. However, recent breakthroughs have led to new treatments. For the treatments to work, the person must get to a hospital immediately.
A. Risk factors of a stroke. B .Warning signs of a stroke. C. Every 3.1 minutes, someone dies of one. D. A stroke can happen to anyone at any moment. E. But you can change or treat other risk factors to lower your risk. F. When that happens, part of the brain cannot get the blood and oxygen it needs. G .The more common kind of stroke is caused by a blood clot that blocks a blood vessel in the brain. |
A. It's not a simple matter to determine the nature of talent. B. Sports team owners spend millions of dollars attracting top talent C. The group interaction and its effect drew the researchers' attention. D. Stars apparently do not follow this basic principle of sportsmanship. E. Several recent studies examined the role of talent in the sports world. F. Building up a dream team is more complex than simply hiring the best talent. G. This task interdependence distinguishes baseball from football and basketball. |
Much of the work in today's world is accomplished (完成) in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. {#blank#}1{#/blank#} Companies spend millions hiring top business people. Is their money well spent?
{#blank#}2{#/blank#} They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team's performance.
To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate (协调) their actions. {#blank#}3{#/blank#} In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team's performance. Young children learning to play team sports are often told, "There is no I in TEAM." {#blank#}4{#/blank#}
Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war (拔河比赛), whenever a person is added, everyone else pulls the rope with less force.
{#blank#}5{#/blank#}. An A-team may require a balance-not just a players, but a few generous B players as well.
