Hello，boys and girls!Today，I am going to talk with what you should do when a fire alarm go off．If you hear the alarm，stand in line at the door and wait your teacher to lead you outside．Stay close to your teacher and classmate．Don't panic or get out of line，and trying to remain quiet and calmly．Soon the firefighters will come and put out a fire．If it's a false alarm and there is no fire，your teacher will lead us back to the classroom．If you notice that when someone is missing and hurt，tell your teacher immediately．

9．A recent survey in the United States showed that the average family spent more money on its pets than on its children．Although rather shocking，it should not surprise anyone who has seen the doggy parlors（客厅） where loved pets rest．Are Americans unique in treating their little friends in this way？No，the English，too，pay more attention to their pets．
This can clearly be seen when we look at pet foods，which often contain more vitamins than human food．They certainly cost much．Last year the British public spent two hundred million pounds on pet food alone，to say nothing of veterinary bills or animal furniture．It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty，so it is not unusual for me to get hot under collarwhen I read an old man left all his money to his dog instead of his children．
There are a variety of reasons why I find pets-raising alarming．They cause physical problems．An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets．Many people find this funny，but in a number of large cities it is a major problem．Animals can cause disease，too．It is the threat of rabies-a disease with no known cure．
Another problem is the carelessness of pet owners．Most little children want a dog or a cat，and they continually push their mothers and fathers until they get one．It is only when the"sweet little thing"has been brought home that the parents realize how much time and money must be spent on"Rover"or"Bonzo"．Then they just abandon it．As a result，they are allowed to run free．English farmers lose hundreds of sheep a year，killed by someone's pet and you must have read of children being hurt by some pets of their own．
Lastly，I would only suggest that we have got our priorities wrong and that something should be done about it．In my view，it's time we stopped being sentimental about pets．I can see no reason why we should get upset when animals are cut up for medical experiments．This will lead us to discovering cures for serious human diseases，then I say，"keep cutting!"

8．The bed should be reserved as a place for sleep，but people tend to read an iPad a lot in bed before they go to sleep．
Charles Czeisler，a professor at Harvard Medical School，and his colleagues got a small group of people for an experiment．For five days in a row，the people read either a paper book or an iPad for four hours before sleep．Their sleep patterns were monitored all night．Before and after each trial period，the people took hourly blood tests to paint a day-long picture of just how much melatonin （褪黑激素） was in their blood at any given time．
When subjects read on the iPad as compared to the paper books，they reported feeling less sleepy at night and less active the following morning．People also took longer to fall asleep on the iPad nights，and the blood tests showed that their melatonin secretion （分泌） was delayed by an hour and a half．
The researchers conclude in today's journal article that given the rise of e-readers and the increasingly widespread use of e-things among children and adolescents，more research into the long-term consequences of these devices on health and safety is urgently needed．Czeisler and colleagues go on，in the research paper，to note："Reading an iPad in bed may increase cancer risk．"
However，software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day，and there are also glasses that are made to filter （过滤） short wavelengths．While they seem like a logical solution for the nighttime tech users，it needs more research．

A．sit in a row and receive the strict tests

A．remove the blue light from your devices completely
B．help prevent eyes being harmed by short wavelength
C．weaken the harm done by doing nighttime e-reading
D．be used in all the e-things widely and safely
31．Which of the following can be the best title for the text？A
A．No e-reading in bed before sleep
B．New software for night e-readers
C．Wrong behaviors before bedtime
D．No games on iPad in bed．

7．Passenger pigeons once flew over much of the United States in unbelievable numbers．Written accounts from the 18^th and 19^th centuries described flocks（群） so large that they darkened the sky for hours．
It was calculated that when its population reached its highest point，there were more than 3billion passenger pigeons-a number equal to 24to 40percent of the total bird population in the United States，making it perhaps the most abundant bird in the world．Even as late as 1870when their numbers had already become smaller，a flock believed to be a mile wide and 320miles （about 515kilometers） long was seen near Cincinnati．
Sadly，the abundance of passenger pigeons may have been their undoing．Where the birds were most abundant，people believed there was an ever-lasting supply and killed them by the thousands．Commercial hunters attracted them to small clearings with grain，waited until pigeons had settled to feed，then threw large nets over them，taking hundreds at a time．The birds were shipped to large cities and sold in restaurants．
By the closing decades of the 19^th century，the hardwood forests where passenger pigeons nested had been damaged by Americans'need for wood，which scattered （驱散） the flocks and forced the birds to go farther north，where cold temperatures and spring storms contributed to their decline．Soon the great flocks were gone，never to be seen again．
In 1897，the state of Michigan passed a law prohibiting the killing of passenger pigeons，but by then，no sizable flocks had been seen in the state for 10years．The last confirmed wild pigeon in the United States was shot by a boy in Pike County，Ohio，in 1900．For a time，a few birds survived under human care．The last of them，known affectionately as Martha，died at the Cincinnati Zoological Garden on September 1，1914．
24．In the 18^th and early 19^th centuries，passenger pigeonsD．
A．were the biggest bird in the world
B．lived mainly in the south of America
C．did great harm to the natural environment
D．were the largest bird population in the US
25．The underlined word"undoing"probably refers to the pigeons'B．
A．escape
B．ruin
C．liberation
D．evolution
26．What was the main reason for people to kill passenger pigeons？C
A．To seek pleasure．
B．To save other birds．
C．To make money．
D．To protect crops．
27．What can we infer about the law passed in Michigan？B
A．It was ignored by the public．
B．It was declared too late．
C．It was unfair．
D．It was strict．
