Solutions to Climate Change
There are personal lifestyle changes that you can make and that,to some extent,can help reduce your carbon impact.Not all are right for everybody.But applying just a few of them could make a difference.
Move closer to work.
Transportation is one of the leading sources of greenhouse gas emissions. (1)CC One way to dramatically cut transportation fuel needs is to move closer to work,use mass transportation,or switch to walking,cycling or some other modes of transport that does not require anything other than human energy.
Consume less.
(2)FF Whether by quitting an automobile or employing a reusable grocery sack,cutting back on consumption results in fewer fossil fuels being burned to extract,produce and ship products around the globe.
(3)AA
A potentially simpler and even bigger effect can be produced by doing more with less.Citizens of many developed countries are energy-wasters,whether by speeding in a gas-wasting vehicle or leaving the lights on when not in a room.Similarly,employing more efficient refrigerators,air conditioners and other appliances can cut electricity bills. (4)DD You can turn the lights or your computers off when you leave the office.
Stop cutting down trees.
When purchasing wood products,such as furniture or flooring,buy used goods or,failing that,wood proved officially to have been sustainably harvested.The Amazon rainforest and other forests are more than the lung of the earth. (5)EE
A.Be energy efficient.
B.Use few electrical appliances.
C.But it doesn't have to be that way.
D.Such efforts can also be usefully employed at work.
E.They may also be humans' short-term hope for limiting climate change.
F.The easiest way to cut back on greenhouse gas emissions is simply to buy less stuff.
G.Citizens spend more money on electricity to power devices when they're off than when they're on.

1.All routes to STEM (science,technology,engineering and mathematics) degrees run through calculus (微積分) classes.Each year,thousands of college students take introductory calculus.But only a small number ultimately complete a STEM degree,and research about why students abandon such degrees suggests that traditional calculus courses are one of the reasons.With scientific understanding and innovation increasingly central to solving 21st-century problems,this loss of talent is something society can ill afford.
Math departments alone are unlikely to solve this dilemma.Several of the promising calculus reforms were spearheaded by professors outside of math departments.STEM faculty are prioritizing cooperation across disciplines to transform math classes to cultivate a diverse generation of STEM researchers and professionals.
This is not uncharted territory.In 2013,life sciences faculty at the University of California,Los Angeles,developed a two-course sequence that covers classic calculus topics,but also emphasizes their application in a biological context.Creating this course,Mathematics for Life Scientists,wasn't easy.The life sciences faculty involved,none of whom had a joint appointment with the math department,said they turned to designing the course themselves after math faculty rejected their request for cooperation.
In Ohio,Wright State University's Engineering departments also revised math offerings.Rather than changing the content of the calculus course,they focused on preparing students for calculus by emphasizing "engineering motivation for math." The approach enhanced opportunities for students with weaker math backgrounds to succeed in engineering and doubled the average graduation rate of engineering students without reducing the average grade of graduates.Math learning is fundamental to all STEM fields,but the opposite also appears to be true.
(1)What problem is mentioned in paragraph 1?
A.Increasing STEM dropout rate.
B.The reform of calculus courses.
C.Shrinking admission to STEM majors.
D.The shaken belief in the role of calculus.
(2)What does "spearheaded" in paragraph 2 probably mean?
A.challenged
B.evaluated
C.cancelled
D.initiated
(3)What do we know about the calculus course reform according to the text?
A.STEM departments made calculus content easier to improve students' grades.
B.Math departments sought cooperation with STEM counterparts to urge reforms.
C.Placing calculus learning in specific STEM contexts is a workable approach.
D.Removing calculus is the key to increasing graduation rate of STEM students.
(4)What does "the opposite" in the last paragraph refer to?
A.The STEM fields may be the foundation of other science subjects.
B.The STEM fields may be central to making math learning effective.
C.Math learning may set barrier for science study in the STEM fields.
D.Math learning may make way for science study in the STEM fields.發(fā)布:2025/1/1 17:30:2組卷:24引用:3難度:0.5 -
2.I once thought that outer beauty is the only factor to become a great person.When I was young,I read many kinds of books,most of which described characters who are handsome or beautiful.So I think that being beautiful is the only way to become a success.
As I grew up,the story of my best friend made me realize that outer beauty was not so important to make a person successful.She is so beautiful a girl that every classmate liked to chat with her,but she was very arrogant(傲慢).In her opinion,she could get all she wanted because of her beauty,but all of her friends left her one by one!Only then did she come to know the importance of the beauty in a person's heart,which changed her attitude and she made friends again.
Turning on TV,we can see many advertisements,most of which seem to give us a feeling that,physical attractiveness is the most important thing. There seems to be a boom in plastic surgery.It is surprising that more and more people,especially girls and women,try it like the first man-made beauty in China,Hao Lulu.It is a common sense that attractive people can easily find work.Most good-looking guys,usually get higher scores in the job interviews.But what is real beauty?I want to say that is inner beauty because those who have beauty in their soul are really beautiful persons.
As is known,the beauty judged with eyes is temporary,so we should concentrate on inner beauty.And if we make the efforts to make our minds beautiful,we'll live a happier life.
(1)Why did the author want to have a good appearance when she was young?
A.Because she wanted to follow the example of her friend.
B.Because she wanted to be one of the characters in the book.
C.Because she wanted to get higher scores in the job interviews.
D.Because the successful characters in the books she read were attractive.
(2)Why did the writer refer to her friend's story?
A.To show how beautiful her friend was.
B.To show how important outer beauty is.
C.To show the importance of inner beauty.
D.To show how terrible to be a beautiful girl.
(3)What does the underlined sentence in the third paragraph mean?
A.Surgery is becoming more and more popular.
B.More and more people pay attention to outer beauty.
C.More people can afford the price of doing plastic surgery.
D.The living standard has been improved over the past years.
(4)Which of the following covers the passage best?
A.Inner beauty is the real beauty.
B.How do attractive persons become successful?
C.The key factor to find a good job is being attractive.

(5)What do we know from the passage?
A.If you are too beautiful,all your friends will leave you out of envy.
B.If you have a good appearance,you must get higher scores in the job interviews.
C.Without the TV advertisements,there wouldn't have been a boom in plastic surgery.
D.Those who have good appearances should also develop the beauty in their hearts.發(fā)布:2025/1/1 18:0:1組卷:12引用:2難度:0.6 -
