Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows,but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out. As a result,the temperature rises.
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it,the earth would be freezing,or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it,so people,plants,and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the each can get unusually warmer, and many plants,animals.and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat,and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually,people,plants,and animals would all die of hunger.
People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now,more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming,kids call do just as much.

A.explain how global warming happens.

[1] HEY boys, attention please! If you want to go to the US one day, you’d better be fully prepared, because, well, you and the boys in the US are a bit different. In my opinion, you’d better try to do the following things.
[2] Firstly, know how to knot a tie (打领带). In the US, every boy above school age wears suits when they go to weddings (婚礼). My friend Madison from Virginia said it shows respect to others. Do you know how to ____________? Learn how!
[3] Secondly, be a gentleman. I know in China some boys are still proud of being strong. But in the US, a good man should also be polite. Here are two examples: holding the door for people behind you and giving the seat on a bus to old people.
[4] The last is to learn something about football and baseball. Chinese boys like ping-pong, basketball and soccer, but American boys love football and baseball. They get very happy when they play and watch these sports. It’s not necessary to be a fan of football or fix (固定) your TV channel to baseball games. But in order to watch the sports with other boys, at least learning some rules would help.
[5] However, all this doesn’t mean that the American way is always the right way. We sometimes need to know the importance of another culture, but don’t feel you have to know that if it makes you uncomfortable. Have fun along the way!

Like many other places in the world, recently, Indiana education officials decided that the schools of the state will not be required to teach handwriting skills to students any longer. Instead, they will focus their energies on teaching students how to type. Is handwriting still an important skill? An online survey received some surprising responses.
Handwriting is not necessary. Students only need to know how to read it, and the only time that they must write something is to make a signature. Why stress them more than they need to be stressed? We already put so much pressure on them to perform on state tests. —Rita
Children don’t write letters now. They send e-mails or text messages. A lot of those old ways are going away. How many bills do you pay by writing a check anymore? —Brown
Although my son is not comfortable with writing, I bought a workbook for him to practice his handwriting. Can you imagine being an adult and not being able to sign a document? —Susan
What a shame! I guess one day it will be a lost art, because handwriting is that personal and beautiful. It has personality —Anna
The school where I worked dropped handwriting several years ago. Unless the students have computers in class, they will not be able to take notes at high speed. I have to speak very slowly and stop after a sentence or two because many students write very slowly. —Helen
The same thing happened here in Tennessee this past year. I think it’s a shame. I just received a handwritten letter from my stepmother and it meant that she spent time sitting and writing. Such a letter brought me a good feeling. —Kathy
Children should still learn writing, for the sake of having a skill that all people can communicate with. I certainly appreciate a handwritten note of thanks or news from my children and grandchildren. —Ruth

It’s good to make mistakes, and here is why.
First of all, mistakes are a clear sign that you are trying new things. It’s always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve? How can you expand? The simple answer is “You can’t.” Look around you. With very few exceptions, either everything you see in your world or every single detail of every single thing is the result of someone trying something new.
Another good thing about mistakes is this: When you are making mistakes, you are learning.Consider this: Edison failed 10,000 times before he perfected the light bulb. When asked how it felt to fail that many times, he said that he hadn’t failed 10,000 times, but rather had learned 10,000 things that didn’t work.
Finally, when you make a mistake you are much closer to success. Why? Because when all is said and done, you will have tried some numbers of things before you succeed.Every time you make a mistake you eliminate one of those things and are one step closer.But this all doesn’t mean that you should go ahead without considering the consequences(后果) of a mistake. Quite the contrary, when you try something new you have to be willing to set some reasonable limits so that in the event that it doesn’t work out the way you want it to, you will be in a position to try again.
We all have limited time and money so don’t blow them all on one approach to a problem. Realize that it probably won’t be perfect the first time and allocate (分配) these resources properly so you can learn, make corrections, and try it again.If you accept and use your mistakes in this way ,you can make great progress in your business and your career.
There is an old saying that goes, “If you’re not making mistakes, you’re not trying hard enough.”
So go ahead and make mistakes. And learn. And grow. And succeed.
From the second paragraph, we can conclude that _______.

A.mistakes are unnecessary for development
B.we are afraid of trying new thing
C.it’s common for people to make mistakes
D.mistakes are better than not trying

The underlined word “eliminate” means _______.

A.avoid B.remove C.accept D.solve

According to the article, one thing you should pay attention to about making mistakes is_____.

A.avoiding making the same mistakes
B.accepting the punishment willingly
C.taking consequences into consideration
D.trying things out one by one

What would the writer probably suggest we say to ourselves when we make a mistake?

A.Never mind, I can always try again.
B.I’d better stay out of trouble.
C.Ok! Now I can learn something.
D.Look at this mess. Anyone would be upset.

General Airport Tips
Plan to get to the airport at least an hour early, or two during holidays and other busy times; this will reduce the stress of the flight. If all goes well, you will have time to relax, shop for last-minute items, or have a meal before the flight.
Flight Delays
Find out why your flight is delayed. Call the free call numbers. Find out if other airlines are experiencing similar delays. If you believe the delay is due to something other than weather or air traffic problems, then mention your suspicion (怀疑) and ask the airline agent to book you on the next available flight, either on the same air-line or a competing one. This is called "Rule 240", and all airlines are required to do it. Use the lingo (行话); ask, "Can you 240 me?" when speaking with an agent. They will know what you mean.
Flight Cancellations (取消)
If your flight is canceled, then make a reservation on the next flight to your destination(目的地). Usually, air-line officials will try to book everyone on their next flight out. Often they will put you on a competitor's next flight only if you request it. If on-time arrival is important to you, when you check flights through our reservation system you can make your choices based on their on-time arrival records. Be sure to also check the weather conditions, as they often affect flight schedules.
Getting bumped (不能登机)
To avoid getting bumped, you must be at the loading gate at least 10 minutes ahead of scheduled departure(离开) for a U.S. Flight, 20 minutes to /from Bahamas, Canada, and Mexico and 30 to/ from all other international points. You must be at the loading gate, not the airport entrance.
