Many parents want to give their children chances to experience a variety of situations.  {#blank#}3{#/blank#}.

    Children, especially boys are expected to be energetic and assertive(果敢的). That doesn't mean, though, that they are allowed to "run wild" in public. {#blank#}4{#/blank#}, particularly in public places and in the homes of others. When a child misbehaves badly, only the child's patents may discipline(约束) him. Other adults should not interfere （干涉） unless the child is doing something which may be harmful to himself.{#blank#}5{#/blank#}. While beating a child's buttocks(屁股), is acceptable to some people, any punishment that wounds the child or leaves a mark is considered child abuse(虐待) and is against the law.

A. The relationship between American parents and their children is harmony

B. In the US, a few religious groups think it is important to have a large family

C. Most parents discipline their children by rewarding good behaviors, not by punishing bad behaviors

D. Having many children would leave the couples and their children less freedom

E. American children are expected to accept invitations to a formal party

F. They bring their children with them to church, to sporting events, to stores, and to social events

G. Parents are expected to keep their children under control at all times

    I was ten when I first sat with my grandmother behind the cashier（收银台）in her general store. {#blank#}1{#/blank#} I quickly learned the importance of treating customers politely and saying “thank you.”

    At first I was paid in candy{#blank#}2{#/blank#} I worked every day after school, and during the summer and on weekends and holidays from 8 a.m. to 7 p.m. My father helped me set up a bank account. {#blank#}3{#/blank#}

    By the time I was 12, My grandmother thought I had done such a good job that she promoted me to selling cosmetics（化妆品）. I developed the ability to look customers directly in the eye. Even though I was just a kid, women would ask me such things as “What color do you think I should wear?” I took a real interest in their questions and was able to translate what they wanted into makeup（化妆）ideas. {#blank#}4{#/blank#}

The job taught me a valuable lesson: to be a successful salesperson, you didn't need to be a Rocket scientist—you needed to be a great listener. {#blank#}5{#/blank#} Except they are no longer women purchasing cosmetics from me; instead, they are kids who tell me which toys they would like to see designed and developed.

    Having bad feeling about world? “Cheer up.” says science writer Matt Ridley. “The world has never been a better place to live in, and it will keep on getting better both for humans and for nature.”{#blank#}1{#/blank#}

1 ) {#blank#}2{#/blank#}

    It is reported that there are more than ten billion different products for sale in London alone. Even allowing for the many people who still live in poverty, our own generation has access to more nutritious food, more convenient transport, bigger houses, and better cars. {#blank#}3{#/blank#} This will continue as long as we use these things to make other things. The more we specialize and exchange, the better off we'll be.

2)Brilliant advances

    One reason we are richer, healthier, taller, cleverer, longer lived and freer than ever before is that the four most basic human needs—food, clothing, fuel and shelter—have grown a lot cheaper. Take one example. In 1800 a candle providing one hour's light cost six hours' work. In the 1880s the same light from an oil lamp took 15 minutes' work to pay for. {#blank#}4{#/blank#} Today it's half second.

3 )Let's not kill ourselves for climate change

    {#blank#}5{#/blank#} A child that dies from indoor smoke in a village, where the use of fossil-fuel (化石燃料) electricity is forbidden by well-meaning members of green political movements trying to save the world, is just as great a tragedy as a child that dies in a flood caused by climate change. If climate change proves to be mild, but cutting carbon causes real pain, we may well find that we have stopped a nose-bleed by putting a tourniquet (止血带) around our necks.

A. Ridley calls himself a rational optimist—rational, because he's carefully weighed the evidence.

B. Overreaction to climate change could prove just as damaging to human welfare as climate change itself.

C. Shopping fuels invention.

D. And, of course, we earn more pounds and dollars than any who lived before us.

E. In 1950 it was eight seconds.

F. It's high time that we took immediate action to fight climate change.

G. Here's how he explains his views.

    After a long day at work, coming home is a breath of fresh air. Home is a comfortable place to sit back and relax. {#blank#}1{#/blank#} Below are a number of things we can do to create a healthy home environment that will help to ease the workday stress and promote our physical and mental health.

    Cleaning the house regularly is the first thing we should do. It may seem like a tiring thing to clean but there is a reason for doing so. We can remove dust by cleaning the house. Leaving layers of dust everywhere means that there is a build-up of dust. And where do these layers of dust go?{#blank#}2{#/blank#}

    Making sure the rooms are full of sunlight is also important. We may not realize it but sunlight is an important part of our growth. We all know that sunlight promotes better working conditions. {#blank#}3{#/blank#} Think about using a Parans system where sunlight does not reach. This technology gathers the sunlight by using solar panels. It can send out sunlight wherever we are.

    {#blank#}4{#/blank#} Going green will help to remove toxins(毒素)in the air. They also give off oxygen, which can lower stress and improve our moods.

    Along the lines of being green, it can also be vital to think about what things we are bringing into the house. Try to avoid specific plastics that are harmful to health. {#blank#}5{#/blank#} They may contain poisonous chemicals that can be breathed in, or simple absorbed through the skin.

A. However, is it as healthy as it can be?

B. Is our home as comfortable as it used to be?

C. Into our lungs.

D. The same thing applies to certain carpets and paint.

E. Besides, it can reduce both stress and high blood pressure.

F. It is also a good idea to add more plants in our house.

G. It is acknowledges that a greener lifestyle is linked to better health.

    Futurologists (未来学家) predict that life will probably be very different in 2050.

    TV channels will have disappeared. {#blank#}1{#/blank#} Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers and books will come to us by computer.

    {#blank#}2{#/blank#} Cars will have computers to control the speed and there won't be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination.

    {#blank#}3{#/blank#} Many factories already use robots. Big companies prefer robots—they don't ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

    {#blank#}4{#/blank#} Today, there are devices (设备) that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again with the help of new technology.

    Scientists will have discovered how to control genes. {#blank#}5{#/blank#} By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?

How to make the most of your time with your host family

Living and studying abroad can be a meaningful and enriching experience. And living with a host family is one of the best ways to immerse（沉浸） yourself in the culture. {#blank#}1{#/blank#} Here are some tips on making the most of your time with your host family.

 {#blank#}2{#/blank#}. You have to understand that host families are sharing the living space with others just because they want to give a kid the opportunity to live abroad. They are willingly changing their lives so you can experience this! With their support, things become easier.

Many people struggle to feel comfortable with their host families at first. This is a completely normal feeling! You've just left everything you've known for years behind to start a new life. It's okay to be confused. {#blank#}3{#/blank#} While you may know the language, some expressions can be hard to understand at first. Be patient with yourself and remember that you will adapt but it will take some time.

Feeling at home can be difficult at the beginning. That's why spending time in common areas is necessary. If you spend all your time in your room, it's going to be hard to feel like you belong . Joining in everyday activities with your host family will help you create a family bond. For example, some families like having dinner together on weekends. Make time for those moments. {#blank#}4{#/blank#}.

Communication is key. If you are unsure about something, ask! It's normal to know few customs and habits at first, so instead of doing things blindly, just ask. Your host family will understand and help you. {#blank#}5{#/blank#} When you are out with your host family, ask them about these, and keep learning them when you are on your own!

A. The language barrier（障碍） can also be a struggle.

B. Showing gratitude will take you a long way.

C. Keep in mind that when in Rome, do as the Roman s do.

D. Then, you'll have chances to expose yourself to their language.

E. It's also normal not to know a lot about unspoken social rules of the country.

F. Not only will they appreciate it but you will also feel like a part of their world.

G. However, living with a foreign family can be difficult and adapting to it can take some effort.
