M: Arm exercises Is that because our arms are too fat or flabby W: Actually, that’s not the main reason. They say that arm exercises are an ideal way to become physically fit. M: But don’t arm exercises raise your blood pressure W: That they do. But the article I read mentioned ways to compensate for that. M: How W: By adding leg exercises, so the arms don’t do all the work. Arm exercises alone aren’t enough to increase metabolism before fatigue sets in it.

International corporate law firm Milbank has discontinued its funding of student events at Harvard Law School, after some of the money was used to pay for pizza at a discussion hosted by a group that supports a one-state solution to the Israeli-Palestinian conflict.Milbank, one of Harvard’s major donors, in 2012 pledged 1 million over the course of five years to help support student-run activities at the prominent law school, located near Boston in the northeastern U.S. But Milbank asked the school to use the money elsewhere “to avoid creating any misimpressions that the firm endorses the viewpoints expressed by any particular organization or journal,” according to a Harvard statement.The move comes after the student group Justice for Palestine held in October discussion called “The Palestine Exception to Free Speech: A Movement Under Attack” aiming to put international pressure on Israel to end its occupation of Palestinian areas.1.What did Milbank do after its fund was used to support an event hosted by the group Justice for Palestine?A) Ask Harvard Law School to withdraw the money.B) Terminate its support for Harvard Law School.C) Stop sponsoring student events at the prominent law school.D) Clear any misinterpretation of their endorsing similar political viewpoints.2.What can be inferred from the student group’s discussion subject?A) They are pro-Israel.B) They hold pro-Palestine viewpoints.C) They stay neutral.D) They suppress advocates of an independent Palestine.

The terms "global warming" and "climate change" are used by many，seemingly interchangeably.But do they really mean the same thing？ Scientists shaped the history of the terms while attempting to accurately describe how humans continue to alter the planet.Later，political strategists adopted the terms to influence public opinion. In 1975，geochemist Wallace Broecker introduced the term "climate change" in an article published by Science.In 1979，a National Academy of Sciences report used the term "global warming" to define increases in the Earth's average surface temperature，while "climate change" more broadly referred to the numerous effects of this increase，such as sea-level rise and ocean acidification（酸化）. During the following decades，some industrialists and politicians launched a campaign to sow doubt inthe minds of the American public about the ability of fossil-fuel use，deforestation and other human activities to influence the planet's climate. Word use played a critical role in developing that doubt.For example，the language and polls expert Frank Luntz wrote a memo encouraging the use of "climate change" because the phrase sounded less scary than "global warming，" reported the Guardian. However，Luntz's recommendation wasn't necessary.A Google Ngram Viewer chart shows that by 1993 climate change was already more commonly used in books than global warming.By the end of the next decade both words were used more frequently，and climate change was used nearly twice as often as global warming. NASA used the term "climate change" because it more accurately reflects the wide range of changes to the planet caused by increasing amounts of greenhouse gases in the atmosphere. The debate isn't new.A century ago，chemist Svante Arrhenius started one of the first debates over the potential for humans to influence the planet's climate.Arrhenius calculated the capability of carbon dioxide to trap heat in the Earth's atmosphere，but other chemists disagreed.Some argued that humans weren't producing enough greenhouse gases，while others claimed the effects would be tiny.Now，of course，we know that whatever you call it，human behavior is warming the planet，with grave consequences ahead.（1）Why did politicians use the two terms "global warming" and "climate change"？ ______A.To sway public opinion of the impact of human activities on Earth.B.To more accurately describe the consequences of human activities.C.To win more popular votes in their campaign activities.D.To assure the public of the safety of existing industries.（2）As used in a National Academy of Sciences report，the term "climate change" differs from "globalwarming" in that ______A.it sounds less vagueB.it looks more scientificC.it covers more phenomenaD.it is much closer to reality（3）What did industrialists of the late 20th century resort to in order to mislead Americans？ ______A.Made-up survey results.B.Hired climate experts.C.False research findings.D.eliberate choice of words.（4）What is the author's final conclusion？ ______A.Global warming is the more accurate term.B.Accuracy of terminology matters in science.C.Human activities have serious effects on Earth.D.Politics interferes with serious scientific debate.
