2、ce lots of methane by breaking down the grass,Now scientists have shown that the pollution fromcows canbe reduced by adding a little seaweed to their food.Scientists first discovered that seaweed could help control methane from cows several years ago.But thiswork was done in a laboratory,there were
3、many questions about whether the idea could work in real life.In the lab studies,the cows were given quite a bit of seaweed,and they would cause losing weight.Thatwasnt helpful,since cows are often sold by weight.It also wasnt clear if the seaweed would stop working if it wasused for a longer period
4、 of time.Now,scientists from the University of California,Davis have answered several of these questions.The researchers studied 21 cows on a farm for about five months.They taught the cows to get their foodfrom inside a special hood,which allowed the scientists to measure the methane that the cows
5、were giving off.This time,they used a much smaller amount of seaweed,which they mixed with the cows food.The results were surprisingly good.In some cases,the cows produced 82%less methane.The improvementdepended on the kind of food the cows were given,but even the worst-polluting cows produced 33%le
6、ssmethane.Over the five months,the scientists didnt see any signs that the cows stomachs were getting used to theseaweed and starting to produce more methane again.Another surprise came when they looked at the weight of the cows.The cows that were fed seaweed gainedjust as much weight as the other c
7、ows,but they didnt need as much food.But there are still some big problems with the idea of feeding cows seaweed.For one thing,theresnotadequateseaweed to feed all of the cows in the world.So farmers would have to figure out a way to grow lotsof seaweed.A bigger problem is that for most of their liv
8、es,cows live in fields,where they eat the grass.That meanstheres no chance to feed them seaweed every day.These problems need to be taken seriously if the world isgoing to avoid the worst effects of the climate crisis.Still,its true that something as simple as feeding cows seaweed can help reduce so
9、me of the pollutioncausing the climate crisis.1.Why did the scientists do the experiment on the farm?A.To control the amount of seaweed.B.To record the weight cows gained.C.To confirm the effect of seaweed in real life.D.To measure the amount of seaweed cows ale.2.The underlined word“adequate”means

11、ndary school subjects.For that reason,someparents and some students feel that the compulsory study of English literature is misguided and disadvantageousto students,particularly if they are second language learners of English.However,there are still good reasons forthe study of English literature.St
12、udents of English language sometimes fail to see the point of studying English literature,especially if theyhave no plans to study English or translation at university.But English literature can introduce students to a rangeof aspects,not only of the English language but also the culture of English-
13、speaking countries.There are aspects of English culture that are summarised by English literature.Of course,this is quite obviouswhen studying the works of Shakespeare or of writers,poets and playwrights of the eighteenth and nineteenthcenturies.It is,however,also true when studying other works of E
14、nglish literature.Students can learn about goodstories and references to different aspects of English culture.They can also learn the context and meanings offamous quotes and phrases.Studying literature does not confine the students to the traditions ofEnglandbut includes the possibility ofintroduci
15、ng them to traditions which inform English literature,such as the study of Ancient Greek drama,and toliterature in other contexts,such as American literature.An enjoyment and appreciation of literature will give students the ability to develop this into an interest inbooks and reading as they move a
16、way from their studies and into the adult lives.They will have the confidence toapproach and cope with new forms of books and writing,since they were exposed to a range of literature duringtheir school days.When studying literature,students can learn not only language aspects such as vocabulary item
17、s but also thelanguage aspects which can be used for specific purposes.For example,if the students are familiar with theconcepts of beat and rhythm of English poems,they can improve their own writing as they are able to appreciateand apply these ideas.Finally,the study of literature can provide stud
18、ents with a fresh and creative angle,from which the studentscan approach their studies in particular and their lives in general.So the next time you are reading a newspaper article complaining of the lack of creativity and initiative in thelocal workforce,remember that in a small way the study of En
19、glish literature can help to add a refreshing andfurther dimension to a persons life.4.The author may agree that the study of English literature_.A.has a long-lasting influence on studentsB.is misguided and has more disadvantagesC.is not necessary for second language learnersD.only allows the studen

24、 years old,the settlement is the work of aculture too simple to have left behind many buried treasures.The single most precious find,to date,is afinger-length sculpture of a silkworm.Nor is the setting lovely:an area surrounded by deafening insects,betweena highway and two power stations.Rather,the
