12．It happens every spring．Flowers come out everywhere on the same day．But how do plants"know"when to flower？
For years，it has been．difficult question for scientists．But a US research group may have finally answered it-the secret lies in a protein（蛋白质）called FKF1．This helps plants to know when the days become long and when they get short．Then they can tell the seasons are changing．
Researchers found the FKF1protein when they were studying a plant called Arabidopsis．It is sensitive to sunlight，and can be made active by sunlight．
Plants produce this protein every day in the late afternoon all year．If there is no light at this time，for example in winter when the sun goes down early，the protein won't be active．But when spring comes and the days get longer，the FKF]protein can he made active by day light and the plants"know"it is time to flower．
"If there is light in the late afternoon，plants will know that the days are getting longer and that it is the best time for flowers to come out，"explained Takato Imaizumi，leader of study．But when conditions are poor for growing，such as during autumn or winter when the weather is cold and days are short，plants won't flower．
Although researchers have only studied how the FKF1protein works in the Arabidopsis，they believe
that it is the same with many other plants，including crops such as rice and wheat．This could be useful to the agricultural industry．
"1f we can control when flowers come out，we might be able to increase crop production．"lmaizumi said．

2Health
A good night's sleep
Do you get the sleep you need？
When the morning sun looks in through our window，do you jump out of bed or go on lying？
Having enough sleep can make the difference between a great day and a terrible one!
Here are the tips for a good night's sleep：
First，go to bed and get up at the same time，even if you haven't gotten a good night's sleep．Sleeping late for just a few days can change your body clock to a different cycle．
Also，avoid big meals at night．Eating heavy，rich food within two hours of bedtime can keep you awake．Your stomach works hard because of those fatty foods，and that may keep you up．
Your body produces a chemical called melatonin that helps you sleep．Light changes the amount of melatonin．It produces more in the evening and less in the daytime．So at night turn off your TV and PC．Also，don't read from a backlit device（有背光的设备） like an iPad．Some scientists think that light from those devices stops your body from making melatonin．So turn those screens off at least an hour before bedtime．
After a good night's sleep，you'll be able to face a new day．

11．Teachers say that the digital age has had a good influence and a not-so-good influence on American teenagers．More than 2，000middle school teachers took an online survey．Researchers also spoke with teachers in some groups．Most teachers think the Internet and digital search tools have had a mostly positive （积极的） influence on their students'research habits and skills．But at the same time，some teachers also point out some problems in teenagers'using digital search tools．
The Pew Internet Project did the survey with the College Board and the National Writing Project．Judy Buchanan is the director of the National Writing Project and a co-writer of the report．She says digital research tools are helping students learn more，and learn faster．"Both teachers and students really welcome these tools because they make learning exciting．And the goal（目的）is to really help students become creators of something meaningful，and not just users of the online information．"
But one problem the survey found is that these technologies make teenagers have short attention spans （持续时间）．As there is lots of information about different subjects on the Internet，teenagers'attention is easily drawn away from their research．
Another problem the survey found is that many students trust the information they find on the Internet too much．Judy Buchanan says these students have not developed the skills to judge （判断） the online information．They need to learn a lot to tell if the information is believable．It's something that really has to be paid attention to．
One more problem the survey found is something that might not seem like a problem at all：being able to quickly find information online．Many students think"doing research"now means just doing a quick search on Google．Teachers say the result is a drop in the wish and ability of their students to work hard to find answers．That is，they are depending too much on search engines and do not make enough use of printed books or research librarians．
Many teachers also say that the Internet makes it easy for students to copy work done by others instead of using their own abilities．

38．The result of the survey showsB．
A．digital search tools need to be greatly improved
B．digital search tools are generally good for teenagers
C．teenagers have difficulty in using digital search tools
D．American teachers enjoy using digital search tools
39．Using digital search tools makes teenagersD．
A．less trusting of online information
B．more independent in doing research
C．more willing to work hard to find answers
D．less able to pay full attention while searching
40．To do better in research，teenagers shouldC．
A．spend more time searching online
B．ask their teachers for more advice
C．make better use of printed materials
D．learn more knowledge of search tools
41．The passage mainly tells usD．
A．all the students like using digital tools
B．the Internet is playing an important role
C．teachers encourage their students to use digital tools
D．digital tools bring about something helpful and problems．
