16.Your smart phone may have hurt you before you realize it.Don't be addicted to it.Put your phone away,OK?
1.Cyber Sickness
Also called"digital motion sickness",symptoms that range from headaches to woozy feelings can occur when you quickly scroll on your smart phone or watch action packed video on your screen.(56)B.Your sense of balance is different from other senses in that it has lots of inputs.When those inputs don't agree,that's when you feel dizziness and sickness.
2.Text Claw
It is the unofficial term for soreness and muscle contraction felt in the finger,wrist and forearm after heavy smart phone use.(57)F.So if you're always on your phone,it makes sense to feel discomfort in your hands and forearms.
3.Eye Strain
Do you stare at a screen for hours on end?If you're reading this,you very well might.(58)G.Staring at your digital devices for a long time can lead to dry eyes,headaches and tiredness,which can decrease your productivity.Experts suggest taking screen breaks every 20minutes.
4.Text Neck
Similar to the claw,text neck---discomfort in the neck and spine happens when you spend a long time looking down at your smart phone.(59)DBeing mindful of how far your neck bends when you're on your phone----and bending it back to an upright position can help reduce the risk of text neck.
5.Pedestrian safety
Pedestrian deaths are on the rise because too many smart phone users engage in distracted walking.While focused on the cyber world,many of us can lose reality of the physical one.Elemental pedestrian safety knowledge is compromised by technology,and the risks are scary.(60)E

A.We should taking breaks for a while.
B.The sensation results from a mismatch between sensory inputs.
C.Remember that pedestrian safety is more important than smart phone.
D.The habit may lead to people requiring medical spine care at a younger age.
E.To avoid injury or worse,put your phone away until you've reached a safe spot.
F.Any specific motor activity can cause pain in the tendons (筋) and muscles when done repeatedly.
G.Any activity that requires active use of your eyes---driving and reading included---can cause eye tiredness.

7.During recent years,floods and flash floods have caused billions of dollars in damage each year.They are among the most common and widespread of all natural disasters.Even more importantly,they're No.1weather-related killer.A flood can happen anywhere along the Mississippi,in New England,even in the desert.
The following are some fascinating facts about floods and flash floods.
A flood(commonly called river flood)is high flow of water from a river or similar body of water,happening over a period of time too long to be considered a flash flood.Flooding is caused in many ways.Winter or spring rains,together with melting snows,can fill rivers too quickly.Heavy rains from hurricanes or other tropical(热带的)systems can also produce river flooding.The Mississippi River Flood of 1993was caused by repeated heavy rain from thunderstorms over a period of weeks.
Flash floods are quickly-rising floods which are usually the result of heavy rains over a short period of time,often only several hours or even less.They can also be caused by ice jams(冰塞)on rivers related to a winter or spring melting,or occasionally even a dam break.The constant influx(汇集) of water finally caused a great overflow to begin,powerful enough to sweep vehicles away,roll big stones into roadways,uproot trees,level(夷平) buildings,and knock bridges down.The speed of the rising of water is the most frightening.
Do remember:Move to higher ground and stay away from low areas during heavy rain.Stay out of flooded areas.Never allow children especially to play or walk in flowing water.Never drive your car into water of unknown depths.

32.What is the best title for the passage?B
A.The power of floods                 B.The facts about floods
C.The occurrence of floods            D.The damage of floods
33.The last paragraph is mainly aboutB.
A.the reasons for floods              B.flood safety tips
C.the waste water systems             D.the swift flood waters
34.According to the passage,people are afraid ofA most during flash floods.
A.the quick rising water
B.the sudden occurrence of flash floods
C.the constant influx of water
D.the great damage of flash floods
35.According to the passage,flash floods areD.
A.great floods resulted from heavy rains in a short time
B.floods happening over a long time
C.quickly-rising floods in a long time
D.floods rising quickly from heavy rains in a short time.

8.A few years ago I decided to grow vegetables in the backyard.I'm an organic(有机的) gardener.I helped run the three-generation-old family vegetables and fruit farm,so I believed I knew much about gardening.
