sagers.cynthia sagers is a biology professor at the university of arkansas.meredith schafer is a graduate student.they were traveling in the state of north dakota on a project.they noticed pretty yellow flowers.they recognized them as canola.farmers grow canola for seeds to make cooking oil.but the canola plants they saw were not growing in farm fields.they were growing along the road.the researchers decided to test the plants.they had brought along special testing papers for the project they were working on.the results showed that the weedy canola plants contained genetic changes.if a plant is genetically modified,that means its genes have been changed to produce desired qualities.this summer,the researchers from arkansas went back to north dakota.this time they went on a road trip to find canola.they traveled more than 5 thousand kilometers.what they found,they say,was the first discovery in the united states of wild canola plants with modified genes.the scientists found canola plants in almost half of the places they investigated.they tested a total of 288 plants.they found that 80% of those plants contained genes from genetically engineered canola.some crop plants are modified to resist damage from the chemicals that farmers use to kill weeds.there are 2 proteins that can give canola the ability to resist 2 commonly used weed killers.one protein gives resistance against glyphosate.the other protein gives resistance against glufosinate.1.which of the following about meredith schafer is not true?a.meredith schafer is a female.b.meredith schafer is a graduate student.c.meredith schafer is the first person who discovered wild canola plants with modified genes in the us.d.meredith schafer comes from the state of north dakota.2.why were the canola plants tested by meredith schafer and cynthia sagers growing along the road?a.because the weather there was special.b.because they were wild canola plants.c.because their genes had been changed.d.because they were planted there by farmers.3.how many plants tested by the scientists contained genes from genetically engineered canola?a.about 58 plants.b.about 230 plants.c.288 plants.d.more than 5,000 plants.4.where most probably can we find this passage?a.in a fashion magazine.b.in a sports newspaper.c.in a comic book.d.in a science book.bare you feeling blue?an american study suggests that being surrounded by happy friends and neighbors could have more of an effect on your happiness than money.that is the finding of researchers from harvard university and the university of california at san diego.nicholas christakis and james fowler studied the emotional health of more than four thousand seven hundred people.they used information from the framingham heart study.that study began sixty years ago in the american community of framingham,massachusetts.it was started to learn more about the risks of heart attack and stroke.for the new study,the researchers examined the emotions of the men and women in the framingham heart study.the information was gathered from 1983 to 2003.the researchers found that friends of happy people had a greater chance of being happy themselves.that means that happiness spreads,or has a contagious effect,among people.and,the smaller the physical distance between friends,the larger the effect they had on each others happiness.for example,a person was twenty percent more likely to feel happy if his/her friend living within one and a half kilometers was also happy.having a happy neighbor who lived next door increased an individuals chance of being happy by thirty-four percent.the effects of friends happiness lasted for up to a year.another finding was that people who worked together or were married did not have as much of an effect on happiness levels as friends did.the researchers said this was often true among friends of the same sex.a report on the findings was published this month in the british medical journal.americas national institute on aging helped to pay for the study.some researchers who were not involved with the study questioned its findings.they said the results could be disputed(争议) unless a separate study showed similar findings.5.what does this text mainly tell us?a.how to live a happy life.b.ones happiness influences others.c.how to keep emotions healthy.d.a scientific experiment.6.from this text we know that .a.nicholas and james based their findings on the study of a medical researchb.nicholas and james have been doing their research for more than twenty yearsc.a person with a happy friend has more chance of feeling blued.a happy person is more likely to suffer from heart attack7.the underlined word “contagious” in the third paragraph means .a.contacting b.embarrassingc.spreadingd.frightening8.according to this text,which of the following four persons may have a larger effect on mrs smiths happiness?a.mr green,smiths former classmate.b.mr thomas,smiths colleague.c.a friend in another city.d.a happy single lady next door.七选五why do we forget things?when it comes to having perfect memories,it is apparent that we humans must have had some faults in our blueprints!why dont we remember everything that we want to remember?it makes us feel upset and get discouraged.1 however,its true that we are all forgetful.2 these are stored in what we call our “long-term memory”.what about before age three?sigmund freud,a doctor of vienna,discovered the fact that we forget most of our early childhood.3 they have different opinions.a very good theory,born from the results of experimentation with babies,is that absence of language ability at the time of an event stopped us from describing it to others.4 experts say that you can keep about seven things in your memory at once for up to three days.during that time,you may forget something in order to put something else in its place,or you put it into long-term memory.what goes into short-term memory are things youve learned about recently,in the past day or two.5 for example,you may have met your favorite star last week,and this week you can tell all the details to a friend.a simple example to explain your short-term memory is to look at a list of twenty words for a minute or two.you will discover that you cannot remember more than about seven of them and that they are the ones in the beginning and at the end of the list because your mind has judged them to be more important than those in the middle.a.scientists now know that it may take longer to remember things for the old.b.however,it is widely recognized that short-term memory can be improved.c.sometimes,it even causes us to lose self-respect or others to think less of us.d.psychologists have been studying what causes this forgetfulness since freuds time.e.most of us have vivid memories of our lives from about age three to our present ages.f.only if something really unusual happens does it stay in your short-term memory for longer.g.the other type of memory,the “short-term memory”,is what we are usually referring to when we say,“i forgot.”.语法填空w:peter,where is your car?i havent seen you drive to
