When we think about the dreams we have, it is surprising to see how many people failed even if they could have succeeded. So today I'm going to tell you five ways to kill your dreams.

    Believe in overnight success.

    Everyone knows the story of a tech guy who built a mobile app and sold it for a lot of money. {#blank#}1{#/blank#} If you investigate further, you will find that he is well educated and has been working on the project for 20 years. Therefore, your overnight success is always a result of what you've done in your life.

    {#blank#}2{#/blank#}

    Constantly, people around you always have opinions on which path you should take. But whichever way you choose, there are other ways you have to pick as well. And one day you need to solve those problems yourself.

Decide to rest when success is guaranteed.

When your life is going great and everything is set— time to rest. Actually, when you're growing towards a peak, you need to work even harder and find yourself another peak. If you were content with what you've accomplished, it would stop you from a greater success.

    Believe the fault is someone else's.

    I constantly see people saying, “I created this great product, but the market is so bad.” If you have dreams, it's your responsibility to make them happen. Yes, the market may be bad. But if no one bought your product, surely there is something there that is your fault.

     {#blank#}4{#/blank#}

    Believe that the only things that matter are the dreams themselves.

    Achieving a dream is a short moment, but your life is not. {#blank#}5{#/blank#} And the only way to really achieve all of your dreams is to fully enjoy every step of your journey.

A. When we face difficulties, believe in ourselves.

B. The overnight success inspires so many people.

C. The story may seem real, but I bet it's incomplete.

D. Be responsible for your own dreams.

E. Life is never about the goals themselves.

F. There's no time to settle down.

G. Believe someone else has the answers for you.

Get a Better Night's Sleep

    You're trying to get a good night's sleep, but why do you still find yourself staring at the ceiling? It's time to listen to what some unexpected experts have to say.

Get the Basic Equipment Right.

    There's really good study on the basic equipment for sleep. {#blank#}1{#/blank#}Firstly, most people prefer a mattress （床垫）that is not too hard and not too soft. Secondly, if your mattress is eight to ten years old, you should get a new one. Seventy-two percent of people said they slept better on their new mattress than they did on their old one.

{#blank#}2{#/blank#}

    Watching TV at night may seem relaxing. However, it beams light into your eyes, which is a “warning” signal for the brain.{#blank#}3{#/blank#}Besides, the cooler white and blue light from a computer screen encourages brain activity and makes your brain difficult to calm down. Download the software at stereopsis.com /flux. It gradually makes your screen less bright at sunset, turning its colors a warmer red one.

Keep you Cool.

    One of the best signals from the body to go to sleep is a decrease in body temperature. I suggest sleeping in a very cool environment, about 19℃. A hot bath will increase your skin temperature, which finally decreases your main body temperature. {#blank#}4{#/blank#}

Make Sleeping Pets Lie.

    Sometimes your dogs might need the noise of machines. Many dogs are sensitive to noises outside, like other dogs barking or neighbors coming home late. A noisy machine will drown out the noises that are keeping your pet up, which keep your pet from waking you. {#blank#}5{#/blank#} If you keep them awake during the day, they're more likely to sleep at night.

 A. Read a book before bed instead.

 B. Take a bath a half-hour or so before bedtime.

 C. You also learn dogs sleep when they're bored.

 D. The dog is very loyal to his master.

 E. It proved two theories.

 F. You don't need a really beautiful mattress.

 G. Switch off the Box.

    If you plan to go abroad for your further education,first you should read something about the custom of the country.For example,in the United States,it is not customary to telephone someone very early in the morning.If you telephone him early in the day,while he is shaving or having breakfast,{#blank#}1{#/blank#}.The same meaning is attached to telephone calls made after 11:00 p.m.If someone receives a call during sleeping hours,he assumes it's a matter of life or death.So{#blank#}2{#/blank#}.

    In social life,time plays a very important part.In the U.S.A. guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date{#blank#}3{#/blank#}.In other areas of the world,it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten.{#blank#}4{#/blank#}.Thus,misunderstandings arise between people from cultures that treat time differently.Being punctual is valued highly in American life,for example.If people are not punctual,{#blank#}5{#/blank#}.In the U.S. no one would think of keeping a business associate waiting for an hour,it would be too impolite.A person who is 5 minutes late is expected to make a short apology.

A.they will not be trusted

B.But it is not true in all countries

C.Different races understand it differently

D.the time chosen for the call communicates its importance

E.they may be regarded as impolite or not fully responsible

F.The meaning of time differs in different parts of the world

G.the time of the call shows that the matter is very important and requires immediate attention

Meat-free Mondays

    In the United Kingdom, vegetarianism (素食主义) is becoming very popular, with around 3 million people in the UK vegetarian.{#blank#}1{#/blank#}However, here in France, I often struggle to find a meat-and-fish-free choice on a menu, which can make eating in restaurants a bit of a challenge.

    People are often curious why I choose to limit my diet in the way I do. There are many reasons why people may choose to be vegetarian. Many people give up meat or fish simply because they do not enjoy the taste. {#blank#}2{#/blank#} They believe it has a bad effect on the environment or it is bad for health. Furthermore, many people are vegetarians to avoid wasting food. In addition, some religious beliefs forbid eating certain meats. {#blank#}3{#/blank#}

    {#blank#}4{#/blank#}However, although sometimes vegetarian food requires a little more creativity, it is very easy to enjoy a healthy and balanced diet as a vegetarian especially when meat substitutes (替代品) are becoming much easier to get.

    Meat-free Mondays is a campaign (运动) to encourage every family to eat just one main meal a week which does not contain meat or fish. {#blank#}5{#/blank#}This is a great challenge for anyone who would like to try out some vegetarian cooking and is a wonderful way to contribute to slowing down climate change.

A.   Young kids prefer meat and fish than vegetables.

B.   Some feel that killing animals for meat is wrong.

C.   Vegetarian food can be delicious and easy to prepare.

D.  The city where I grew up is known as the „vegetarian capital' of the UK.

E.   Overall, vegetarians usually have different reasons for choosing their lifestyle.

F.   The purpose of the campaign is to protect the environment and to improve health.

G.  A common misunderstanding about vegetarian food is that it is not tasty or healthy.

Mystery of Mosquito Flight

    The mosquito is a troublesome and dangerous insect. Their bites itch and can carry dangerous diseases, like malaria, Zika virus and yellow fever. Recently, researchers from Britain and Japan discovered how mosquitoes fly. {#blank#}1{#/blank#}

    Mosquito wings are small and have an uncommon shape.{#blank#}2{#/blank#} So, how is their flight possible? The team of scientists from Britain and Japan solved the mystery. They used high-speed cameras and computer images to understand the mechanics of how the insect moves its wings to stay in the air.

    {#blank#}3{#/blank#} They set up eight super-high speed cameras that take 10,000 images each second. Simon Walker, a researcher at the University of Oxford, explains that normally at least two cameras are needed to record an insect, so they've got enough views of an insect. With two camera views they can then take any point on an insect and calculate its 3-D coordinates (三维坐标).

    Mosquitoes can spread diseases. The insect has two antennae, or tall, thin organs on its head that it uses to feel things. But its antennae and six legs make it difficult to take clear images of the wing movements. {#blank#}4{#/blank#} The extra cameras let the researchers see that the mosquito's wings move eight hundred times each second. That is four times faster than many insects of a similar size.

    Mosquitoes fly by moving their wings in several different directions. The thin top edges of their wings move forward first and then they change direction and move down. The movement looks as if the wings are drawing the number eight. {#blank#}5{#/blank#} Walker says that existing unmanned flying devices do not work very well outside because wind can affect their flight.

    "Insects, on the other hand, deal really well with even quite windy conditions. So understanding how they can do this is going to be advantageous to us." These researchers say that understanding how mosquitoes fly might help find ways to stop them from spreading diseases.

A. Because of this, it is hard to believe that they are able to fly.

B. Mosquitoes evolved from other insects about 226 million years ago.

C. So, the team needed to use eight cameras to view the wings from many directions.

D. Researchers at the University of Oxford took images of mosquito wing movements.

E. Many measures have been tried for mosquito control, for example, getting rid of breeding places.

F. This knowledge, they say, help find ways to stop mosquitoes from spreading diseases in the future.

G. The research team believes the mosquitoes' wing movements could help inventors design new flying devices.

After building some "standard"cargo bikes， {#blank#}1{#/blank#} ，this time with something very special. I wanted to build an ideal cargo bike combining the stability of a three-wheeler with the possibility to change directions like being on two wheels. 
The first step was to do extensive research {#blank#}2{#/blank#} .An incredible source of technical inspiration was the online Tilting Group.Although primarily-concerned with tilting（倾斜） concepts of engine driven constructions，the group is surely the best place to find information about constructing a tilter. 
    After researching and outlining a few ideas，I grabbed some parts and started with a very simple prototype（雏形）.Building such a vehicle needs a high degree of accuracy，which was not the case with my prototype {#blank#}3{#/blank#} .So I made a few more sketches（草图），which led to an improved version of the driving and tilting mechanism. 
    Then I started building the tricycle.Building the structure was quite straightforward.As usual I took an old bike apart for the back triangle and then added the front part.After adding a cargo basket to the structure， {#blank#}4{#/blank#} . 
    Now came the hard part：the driving mechanism.I started with the usual design used for two-wheel cargo bikes，but it took me quite some time to figure out how to pass the driving force to both wheels without allowing the whole thing to lock itself in any angle {#blank#}5{#/blank#} ， but I'm sure I can use the knowledge I gained one way or another. 

A.The project was demanding 
B.I decided to get my hands dirty again 
C.I fell in love with three-wheeler bikes 
D.I put all the parts together for the first time 
E.It took me quite some time to understand the ideas behind it 
F.The engine driven constructions were always the most difficult to fix 
D.The consequence was that the driving mechanism locked itself occasionally
