Read the following article and select the best answer. Article: My students often tell me that they don't have "enough time" to do all their schoolwork. My reply is often a brief "You have as much time as the president."I usually carry on a bit about there being twenty-four hours in the day for everyone, and suggest that "not enough time" is not an acceptable explanation of not getting something done. Once in graduate school,I tried to prove to one of my professors by saying that I was working hard.His answer to me was. "That's irrelevant .What's important is the quality of your work. " Since then I have had time to think carefully about the "hard worker" dodge ,and I have come to some conclusions--all relevant to the problem of how much time we have. If you analyze the matter, you can identify two parts of the prob1em:There is, of course,the matter of "time", which we call think of as fixed. Then there is the problem of "work" during that time. But, as my professor suggested, it's not how hard one works but the quality of the product that's important. That led me to a new idea: the quality of the work.That concept is perhaps best explained by a sign I once saw on the wall in someone s office: "Don't work harder. Work smarter." There is a lot of sense in that idea. If you can't get more time,and few of US can,the only solution is to improve the quality of the work.That means thinking of ways to get more out of the same time than we might otherwise get.That should lead us to an analysis of our work habits.Since "work" for students usually means "homework", the expression "work habits' should be read as "study habits". Then, as a smart student,you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better,there are big advantages that pay off in all your studies. Question: What's the passage mainly about? - Students don't have enough time. - Don't work harder; work smarter. - No one can get more time. - Read better and write better.
Don't work harder; work smarter.

Read the following article and select the best answer. Article: Linus Pauling,the only person who has won two undivided Nobel Prizes,was born in Portland,Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962,long after he had received his Bachelor's degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it. He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the "behavior" of molecules led him from physical chemistry to biological chemistry,especially of the human body. He began with proteins and their main parts,the amino acids ,which are called the"building blocks of life".In 1950,he constructed the first satisfactory model of a protein molecule,a discovery very important to the understanding of the living cell. During World WarII,Pauling was a member of the Research Board for National Security,for which he was awarded the Presidential Medal of Merit in 1948. However,the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules,he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures. From then on,Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts,The NuclearTestBan Treaty,declaring all nuclear tests to be illegal except underground ones,came into effect on October 10,1963,the same day Linus Pauling was awarded the Nobel Peace. Question: Which of the following things did Pauling pay much attention to at first? - The "behavior" of molecules. - Physical chemistry. - Biological chemistry. - The human body.
Physical chemistry.

Read the following article and select the best answer. Article: One of my longest-running battles with my kids is about manners specifically,about whether it's necessary to send hand-written thank-you notes for gifts.I say yes,and my children have continued throughout their teens to write the notes.But they grumble that I'm out of step with the times. If a new BabyCenter poll is any guide, _ .A surprisingly large number of parents still insist that their children practice such old-fashioned manners as putting pen-to-paper to say thank you,treating adults with respect and addressing adults as "Mr., Mrs.or Miss."A majority of the 1,000 parents surveyed also said they insist at dinner that children keep napkins in their laps,ask to be excused from the table and refrain from talking with a full mouth. Among the reasons cited most often by parents,BabyCenter says,is that "the world is a more free-wheeling place,and they want to give their kids a stronger moral compass to guide them."This thinking was affirmed by 64%of those surveyed.And 58%say they see so many badly behaved kids around them that they're determined to raise their children differently. This poses a particular challenge for parents who work outside the home and must find a sitter, nanny or other child-care provider who will insist on the manners they consider most important. Pediatrician Perri Klass wrote recently in the New York Times about her annoyance at a rude,demanding child who was among her longtime patients.Although she veiled her injunctions to the mother in euphemisms ,talking to her about "setting limits,"Dr.Klass wrote,"I do pass judgment on kids with bad manners and so does every pediatrician I know."Rude kids make her wonder whether there is something wrong with the family,among other things,she says."The whole 'manners' concept might seem a bit odd,"she says,"until you recast it as 'social skills' a hot-button child-development issue,as I wrote in a recent column." Readers,what manners do you insist upon for your children? Has other kids' bad behavior led you to toughen your standards? Do the... Question: According to Perri Klass,it can be inferred that_. - it is hard to help the rude children to get rid of the bad manners - parents ought to set up a good example for their children in good manners - it is the society that should take on the responsibility to educate children - parents and society don't have any influence over the rude children
parents ought to set up a good example for their children in good manners
