Einstein was born in 1879 in Germany. As a child, he was slow to learn to talk. As a pupil, he was backward. But when he was fourteen years old， he became clever. He taught himself math from textbooks. He studied hard because he wanted to be a physicist.
In 1901，Einstein began teaching. In 1902 he continued his studies at the University of Zurich. Several years later, he formulated (系统地阐述)his famous Theory of Relativity (相对论). To most people the law of relativity is difficult to explain. But once Einstein explained it very well to a group of young students. He said, "When you sit with a good girl for two hours, you think it is only a minute. But when you sit on a hot stove for a minute, you think it's two hours. That is relativity."
After Hitler came into power in Germany, Einstein went to America. In 1940 Einstein became an American citizen. In 1955， Einstein's life ended at the age of seventy-six. The law of relativity is ______ .
| A．very hard for most people to understand |
| B．too hard for Einstein himself to explain |
| C．too hard to explain to anybody except Einstein |
| D．easy to understand only for the young students |

Did you get a flu shot this year？For the first time，the Centers for Disease Control and Prevention in the US is recommending that all children aged from 6 months to 18 years receive the flu vaccine.
Vaccines battle diseases caused by bacteria and viruses.A weakened form of the germ (病菌) is introduced into the body.The body makes special substances called antibodies (抗体) to fight the germs.If the actual germs were to attack，the antibodies would fight.Because there are many kinds of flu viruses，scientists must create a new vaccine formula (处方) each year.Researchers must make a prediction.
It is like forecasting the weather.Sometimes they are right on，and sometimes they are off.But even when the vaccine does not closely match circulating flu types，it can make the illness less serious.
“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles vaccine，” says Dr.William Schaffner of Vanderbilt University School of Medicine.“It’s not a great vaccine，but it is in fact quite a good vaccine.”
But a flu vaccine doesn’t work for everyone.There are certain people who should be careful about taking it，because the vaccine is produced in eggs.Those who are allergic (过敏的) to eggs should not take it.If you have a fever，you should wait until you recover.
Some people are afraid that they might get the flu from the flu shot.Scientists say that it is not possible，because the viruses in the flu shot are inactivated.But some minor side effects such as lowgrade fever and body ache could occur.If they do，they begin soon after the shot and usually last only one to two days.
Did you know？Smallpox was the first disease people tried to prevent by putting a virus into a healthy person.In 1796，English scientist Edward Jenner placed some infected material under a boy’s skin.The underlined word “vaccine” (in Para.1) refers to________.
| A．virus used for fighting against disease |
| B．antibody to fight the germs |
| C．formula to fight against disease |
| D．germ to be injected into the body |
By saying “It’s not a great vaccine，but it is in fact quite a good vaccine.” (in Para.4)，William Schaffner means the flu vaccine________.
| A．is as effective as the polio and the measles vaccines |
| B．is worse，compared with the polio and the measles vaccines |
| C．does help to make illness less serious |
| D．is quite good because it works for everyone |
We can infer from the passage that________.
| A．those who are not allergic to eggs can take the flu vaccine |
| B．not all the flu vaccines are effective for everyone |
| C．you should go to a doctor if you have a fever after taking the flu vaccine |
| D．it is possible that some people might get the flu from the flu shot |
When people take the flu vaccine，________.
| A．they’ll be allergic to eggs |
| B．their bodies will ache for 5 days |
| C．they probably have a low fever |
| D．they won’t catch a flu ever after |
As you can see，water works hard in your body every day.That’s why it’s important to give your body the water it needs to carry out all its different jobs.On a regular day，your body loses 2 to 3 quarts of water—enough to fill a 2liter soda bottle.You probably guess that water is lost when you sweat—especially on a hot day.
But your body also loses water in an almost invisible way—evaporation (蒸发)．Water escapes from your body through your skin and in your breath.How？Your breath contains droplets (小滴) of water that are usually too tiny to see.They become visible for a quick second in the cold when you can “see your breath”．But water evaporates this way all year round.Your skin also contains water，which escapes in tiny droplets that go into the air.The water in your skin evaporates into the air，but fortunately，your body can replace the water it loses so your skin doesn’t dry out.
Eating and drinking is one way to replace the water your body loses.Most foods have a lot of water in them，especially fruits and vegetables.Grapes，watermelons，oranges，and cantaloupes are delicious and full of water.
But you can’t rely_on food alone to get that water back，and that’s why it’s also a good idea to drink water every day.You might have heard someone say that people need to drink 6 to 8 cups (1.4 to 1.9 liters) of water each day.Depending on how much water you’re getting from foods and other liquids,6 to 8 cups might not be necessary.If you eat a lot of fruits and vegetables，or you like to eat soup every day，you’ll get some of the water your body needs.You should drink enough water every day because________.
| A．your body needs too much water |
| B．water does all kinds of jobs in your body |
| C．your body loses a lot of water every day |
| D．the more water you drink the better you feel |
Water in your body loses by the following ways EXCEPT________.
| A．breathing | B．evaporating |
| C．sweating | D．eating |
Your body has to give enough water to your skin in order to________.
| A．keep the water in your skin clean |
| B．stop your skin from drying out |
| C．stop the water from losing |
| D．keep your skin clean all the time |
What does the underlined phrase “rely on” in the fourth paragraph mean?
| A．Eat up. | B．Receive. |
| C．Depend upon. | D．Digest. |
Several parents and children escaped the summer heat and enjoyed a refreshing “Leap Into a Good Book”．About 30 children and parents gathered as volunteers for both agencies.
After the readings，refreshments (点心) were offered and children and parents were given books，a gift bag and a bookmark with information on adult literacy (读写能力) programs.
Learn to Read of Northwest Florida Inc.and Even Start coordinated the event with hopes that combining their programs will help target functionally illiterate adults and their families.A functionally illiterate adult is one who has reading skills below a seventhgrade level.That often means they have difficulty filling out job applications，understanding a lease，reading medication labels or to their children.
Merelin Hernandez,9，a fourthgrader at Warrington Elementary School，understands the importance of reading.She also says it makes her happy when she is bored.“Reading helps me go to another grade，”she says.“I feel proud when I get a B because then I know I am reading well.”Monae Walker,7，a student at Oakcrest Elementary School，says reading teaches her and makes her happy.
Learn to Read of Northwest Florida Inc.provides oneonone tutoring for basic reading and writing skills to adults 16 and older who are not in school.Tutors go through a 12hour workshop and tutor their students 3 hours per week.The program currently has 150 active tutors.
Even Start is a family education program at McMillan Learning Center，which offers adult education classes and infant，toddler and prekindergarten services at no cost to families.Linda Harris，a teacher in charge of the Escambia Even Start program，says the program equips parents so they can help their children.The event “Leap Into a Good Book”________．
| A．was mainly held by Learn to Read |
| B．targeted functionally literate parents |
| C．was attended by about 30 volunteers |

William Henry Bragg was born at Westward，Cumberland，on July 2,1862.He was educated at Market Harboroagh Grammar School and afterwards at King William’s College，Isle of Man.Elected as a minor scholar of Trinity College，Cambridge，in 1881，he studied mathematics under the wellknown teacher，Dr E．J.Routh.He studied physics in the Cavendish Laboratory during a part of 1885，and at the end of that year he was elected to the Professorship of Mathematics and Physics in the University of Adelaide，South Australia.
His research interests dealt with a great many fields and he was skilled at picking up a subject，almost casually，making an important contribution，and then dropping it again.However，the work of Bragg and his son Lawrence in 1913～1914 founded a new branch of science of the greatest importance and significance，the analysis of the crystal structure by means of Xrays.It is true that the use of Xrays as an instrument for the systematic revelation of the way in which crystals are built was entirely due to the Braggs.This was recognized by the award of the Nobel Prize jointly to father and son in 1915.
He was an honorary Doctor of some sixteen universities，and a member of the leading foreign societies.Many other medals and awards were bestowed upon him among which may be mentioned the Rumford Medal in 1916 and the Copley Medal (its premier award) in 1930.
He was the author of many books，including Studies in Radioactivity，XRays and Crystal Structure，The World of Sound，Concerning the Nature of Things，Old Trades and New Knowledge，An Introduction to Crystal Analysis，and The Universe of Light.His favorite hobby was golf.After a life of astonishing productiveness，Sir William Bragg died on March 10,1942.William Henry Bragg was awarded the Nobel Prize because________.
| A．he succeeded in using Xrays to find out the crystal structure |
| B．he was the first to use Xrays to help to do his experiment |

Electric cars are dirty.In fact，not only are they dirty，they might even be more dirty than their gasolinepowered cousins.
People in California love to talk about “zeroemissions vehicles”，but_people_in_California_seem_to_be_clueless_about_where_electricity_comes_from.Power plants mostly use fire to make it.Aside from the new folks who have their roofs covered with solar cells，we get our electricity from generators.Generators are fueled by something—usually coal，oil，but also by heat generated in nuclear power plants.There are a few wind farms and geothermal(地热的) plants as well，but by far we get electricity mainly by burning something.
In other words，those “zeroemissions” cars are likely coalburning cars.It’s just because the coal is burned somewhere else that it looks clean.It is not.It’s as if the California Greens are covering their eyes—“If I can’t see it，it’s not happening.” Gasoline is an incredibly efficient way to power a vehicle；a gallon of gas has a lot of energy in it.But when you take that gas(or another fuel) and first use it to make electricity，you waste a nice part of that energy，mostly in the form of wasted heat—at the generator，through the transmission(传送) lines，etc.
A gallon of gas may propel your car 25 miles.But the electricity you get from that gallon of gas won’t get you nearly as far—so electric cars burn more fuel than gaspowered ones.If our electricity came mostly from nukes；or geothermal，or hydro，or solar，or wind，then an electric car truly would be clean.But for political，technical，and economic reasons，we don’t use much of those energy sources.
In addition，electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill.And finally，when cars are the polluters，the pollution is spread across all the roads.When it’s a power plant，though，all the junk is in one place.Nature is very good at cleaning up when things are too concentrated，but it takes a lot longer when all the garbage is in one spot.What does the underlined part mean in Paragraph 2?
| A．People see the California Greens everywhere. |
| B．People in California love to talk about zeroemissions vehicles. |
| C．People in California love to have their roofs covered with solar cells. |
| D．People in California have no idea that so far electricity mainly comes from burning coal，oil，etc. |
What is the main idea of the text?
| A．Electric cars are not clean at all. |
| B．Electric cars are better than gasolinepowered ones. |
| C．People cast doubts on electric cars’ batteries. |
| D．Gasoline is an efficient way to power a vehicle. |
The electricity we get from a gallon of gas may make our car run ________.
| A．not less than 25 miles |
| B．as far as 50 miles |
| C．as far as 25 miles |
| D．not more than 25 miles |
It can be inferred from the text that ________.
| A．being green is good and should be encouraged in communication |
| B．electric cars are not clean in that we get electricity mainly by burning something |
| C．zeroemissions vehicles should be chosen to protect our environment |
| D．electric cars are now the dominant vehicle compared with gasolinepowered cousins |
