18．A solar bag is a long plastic bag made from very thin plastic and colored black to take in solar energy．The heated air inside the bag causes the bag to float．Although the solar bag looks similar to a regular black trash bag，the key difference is the thickness of the plastic．A great science experiment might be testing bags of different thicknesses to see which one floats the highest!
Materials
v  Solar bag
v  Solar bag string
Notice that the bag is made out of a lightweight plastic material．Be careful when dealing with the bag since the pla stic will tear easily．
Carefully take the plastic bag from the packaging and hold one of the op en end of the bag．Tie this end with string．
The best time for a launch is in the cool morning．We have not had much success with a launch in the middle of a hot day．
Choose a proper place for the launch．Find a field clear of any buildings，trees and power lines．Choose a day to do the experiment when it is sunny and free of any wind．
Put the solar bag onto a soft surface like grass．Have one person hold the bag open as you begin to run around and fill the bag with air．
Fill the bag with air until about 2 feet remains without air so that you can hold it in your hand．Close the end and use a string to keep it on the ground．
The last part of the work is done by the sun．Gather around the giant bag but try not to touch it-sharp fingernails will easily break the thin plastic．Be careful!The outside of the bag also gets very hot to the touch．It's important to remember that it may t ake as long as ten minutes for the air inside to heat up enough to cause the bag to float．

16．Professor David Agus，one of leading scientists at the medical revolution，says that he believes that with our current technology humans have the potential to regularly live into their ninth or tenth decade．
Craig Venter，co-founder and CEO of Human Longevity Inc．，says there might be no supposed limit to how long we can live，but that"we need to make sure we can support extra long life on this planet．"Huge advancements at the intersection （交叉领域） of medicine and technology，such as big data，are making these kinds of developments in aging possible．
Venter explained that when he first studied the human genome （基因组） 15 years ago，there was nothing for him to compare it to．For example，we now know that we vary about 3% from the 6.4 billion letters of DNA that we get from our parents．Ten years ago，Venter said he wouldn't have thought that we'd be able to predict someone's age from their genetic code．We also now know that our genetic code is constantly changing，he says．Men，for example，start losing Y chromosomes （染色体） in their 40s and 50s．"To help crack （破解） the big data code in medicine，my team have hired the engineer who designed Google Translate，"says Venter．"We're using machine learning to try to understand and translate all that data，"he explains．"We now have the ability to produce a photo of someone straight from their genetic code．"
Therefore，will all this data automatically extend our lifespan？That's a bit more complicated．"We're learning new things every six months，"Agus says．"These new things make us more complex．That means we're never going to totally understand disease，"he adds．"But we don't need to understand it to control it．"
32．What is the belief that David Agus holds？C
A．There will be no disease in the future．
B．Our life expectancy will slowly increase．
C．Everyone can live a long life in the future．
D．Advance in technology can make us stop aging．

C．guess his appearance                   
D．stop him from aging

13．As time goes on，people have come to realize the importance of protecting the environment．But they can't deal with everything by themselves．Take small steps，and you can make a difference．
●Think Green．Think about the environment as you live your life．If you turn off lights and TV when leaving the room，you'll save energy．If you take shorter showers，you will save water．
●Shop Green．Shopping is fun，but buying things you don't need is wasteful and even bad for the earth．Before you buy something，ask yourself how much you will use it，and whenever possible，buy things locally made instead of those shipped from far away．
●Dress Green．What really matters is not the colour．It's how the clothes were made．So look for products made from environmentally friendly（环保的） materials．
●Study Green．What's better than learning about the environment？Save it while you learn．It can be as simple as using both sides of a piece of paper before you recycle it．
25．What does the writer want us to do？D
A．Know some facts．

20．Cheektowaga Central Middle School can be a lot of fun．It has game nights and student dances，after-school activities，and sports teams．However，students must earn the right to join in the fun．If they don't behave well，they're banned from participating in after-school activities．
Teachers and parents say the threat （威胁） of being excluded （排除在外） appears to be working．Kenny says it taught him that actions have consequences："I learned that I need to be balanced in both my work and athletics to be rewarded for working hard．"Parent Sondra LaMacchia told The New York Times that her 14-year-old daughter is learning responsibility at Cheektowaga Central．She used to perform poorly in her studies，so then she was banned from a school dance．The message got through loud and clear．"It's nobody's fault but hers，"LaMacchia said．
Although exclusion（排挤）may help teach responsibility，some psychologists say it can also be threatening，especially for students who often cause，or may cause，trouble in school．They might become more aggressive and antisocial，which is exactly what schools like Cheektowaga Central want to prevent．
Should schools exclude students from activities to get them to behave well？I believe teens need school activities and that inclusion（包含） can be the answer．For some troubled students，activities can be their motivation to stay in school．"Activities such as sports may be the only thing keeping certain students in school，"says Duace Wood，a teacher at Mohonasen High School in Rotterdam．Getting involved in after-school activities keeps troublesome students in class．Even if they don't do as well as their classmates，they are still learning．The more time they spend at school，the less time they have to think about starting trouble．Teams also provide support and role models，and they help build the confidence that students need to succeed．If students who don't behave well are banned from activities，they might give up on school altogether．

17．The reason why he was fired isthathe was too careless．
18．Overall，gender（性别）differences in math tend to be small．Statements like"Boys do better than girls in math"should not be read as one that all boys perform better than all girls in math．In some recent studies almost no differences have been found．For example，in the national Assessment of Educational Progress study，there were no great difference in the average scores of eighth and twelfth grade boys and girls．
As a math teacher，I hope to do everything in my power to encourage girls to have more confidence in math．Of course I want every girl and boy in my class to see that they can succeed in math．I do not allow boys monopolize（垄断）the answering of questions in my classroom．I call on girls and boys equally and I don't let any student get away by saying"I don't know"or by shrugging their shoulders．I will guide students to a solution．
In one project I assign to my 8th grade algebra（几何）students，they have to research a mathematician and report to the class．I encourage as many students as possible，boys and girls，to research some of the famous female mathematicians．When the girls see how much women had to do to study mathematics years ago，it helps them to see how fortunate their opportunities are today．In this way I provide girls with positive math experiences．
