The Internet has become part of teenage life. There’s a report on 3,375 students aged from 10 to 18 in seven Chinese cities. It says that 38 percent of them believe they use the Internet often. While most of them get useful information and use the Internet to help in their studies, some are not using it in a good way. Many are playing online games too much. A few even visit websites they should not look at. Bad things can happen if young people spend too much time on the Internet.

In order to help young people use the Internet in a good way, a textbook on good Internet behavior has started to be used in some Shanghai middle schools this term. It uses real examples to teach students all about good ways of using the Internet. It gives useful advice such as it’s good to read news or find helpful information to study. Some students also make online friends. But if you are meeting a friend offline, let your parents know.

Teachers and parents all think the book is a very good idea. It will teach students how to be a good person in the online world. It will be a guide for teens to use the Internet and keep students away from bad sites.

10.In its early history,Chicago had floods frequently,especially in the spring,making the streets so muddy that people,horses,and carts got stuck.An old joke that was popular at the time went something like this:A man is stuck up to his waist in a muddy Chicago street.Asked if he needs help,he replies,"No,thanks.I've got a good horse under me."
The city planner decided to build an underground drainage (排水) system,but there simply wasn't enough difference between the height of the ground level and the water level.The only two options were to lower the Chicago River or raise the city.
An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt.This raised the level of the city's streets by as much as 12feet.
This of course created a new problem:dirt practically buried the first floors of every building in Chicago.Building owners were faced with a choice:either change the first floors of their buildings into basements,and the second stories into main floors,or hoist the entire buildings to meet the new street level.Small wood-frame buildings could be lifted fairly easily.But what about large,heavy structures like Tremont Hotel,which was a six-story brick building?
That's where George Pullman came in.He had developed some house-moving skills successfully.To lift a big structure like the Tremont Hotel,Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation.One man was assigned to operate each section of roughly 10jackscrews.At Pullman's signal each man turned his jackscrew the same amount at the same time,thereby raising the building slowly and evenly.Astonishingly,the Tremont Hotel stay open during the entire operation,and many of its guests didn't even notice anything was happening.Some people like to say that every problem has a solution.But in Chicago's early history,every engineering solution seemed to create a new problem.Now that Chicago's waste water was draining efficiently into the Chicago River,the city's next step was to clean the polluted river.
51.The author mentions the joke to showB.
A.horses were fairly useful in Chicago
B.Chicago's streets were extremely muddy
C.Chicago was very dangerous in the spring

A.It went on smoothly as intended.
B.It interrupted the business of the hotel.
C.It involved Pullman turning ten jackscrews.
D.It separated the building from its foundation.

15.Scientists this week announced that lightning can travel much farther and last much longer than previously thought.
The conclusion is based on observations of a storm in Oklahoma(hat produced a lightning bolt(霹雳)nearly 200 miles long.nearly half the width of the state.The longest-lasting flash was observed in southern France.where a single flash in 2012 lasted for 7.74 seconds.Most lightning bolts last less than a second and travel only a few miles.
"We should be more aware of lightning if wc can have lightning (hat can travel 200miles."said Randy Cerveny,the spokesman on weather and climate extremes for the World Meteorological  Organization,which added.for the first time,lightning to its list of extreme weather events.This list includes records for heat,cold,wind speed,rainfall and other events.
Scientists said that the Oklahoma lightning bolt shot from Tulsa,Okla.,westward,nearly to the Texas border.It touched the ground in several places.
The lightning can start tens or hundreds of miles away and then come back to where we are.That's why we have to be careful of where the lightning is coming to ground,even though the storm is past.
Of course not all storms have extreme lightning like that observed in Oklahoman and French storms.The Oklahoma bolt came in the midst of a particularly bad patch of weather early on June 20,2007.
"Most lightning will strike within the 30-30rule,"said Dr.Cerveny."The 30-30 rule is one that we still want to stress and make sure people are aware of…but it does confirm that lightning can hit far from where the storm actually is."
The"30-30"rule stipulates(规定)that if thunder follows lightning within 30 seconds,people should go inside for 30minutes.If it lakes longer,it's safe to stay outside.
Studying lightning is important because it can be fatal when it strikes.This year,35 deaths have been blamed on lightning striker,according to data from the National Oceanic and Atmospheric Administration.That's the highest death toll related to lightning strikes in any single year since 2007,reports The Weather Channel-
Though thunder is just the sound of lightening,the rumble(隆隆声)arrives after the  light flash during a storm?because light travels much faster than sound.The booming sound is a shock wave caused by the rapid expansion of air suddenly heated by the lightning holt.

B.parallel hurricanes in their harm to humans
C.impact on people in a larger area than rains

A.when we can carry out observations on lightning bolts
B.what the relationship is between lightning and a storm
C.where lightning may possibly reach and cause damage
D.how we might keep ourselves safe from a lightning bolt
63.We can conclude from the passage thatA.
A.the longer distance a bolt covers,the more dangerous it may be
B.lightning bolts tend to take place in extremely hot summer days
C.we mustn't stop caring about the bolts until I hey come to an end
