Listen to the following lectures. Then answer the questions.
Lecture 1
What is true about land turtle?
Correct
The land tortoises are the tortoises that don’t live in the water. They only come to water to drink or bathe.
A French explorer captured an adult tortoise, which is called Marion’s Tortoise, in 1766, and he transported the tortoise to the island of Mauritius in that year. It died in 1918. But is is not clear who old it was when id died. It is possible for a Tortoise to live 200 years.
لاک پشت های خشکی زی لاک پشت هایی هستند که در آب زندگی نمی کنند. آنها فقط برای نوشیدن یا استحمام وارد آب می شوند. یک کاوشگر فرانسوی در سال 1766 یک لاک پشت بالغ به نام “لاک پشت ماریون” را در سال 1766 در دام انداخت و آن را را به جزیره موریس انتقال داد. در سال 1918 لاک پشت درگذشت. اما مشخص نشد که لاک پشت چند سال سن داشت. ممکن است یک لاک پشت حدود 200 سال عمر کند.

Lecture 2
how do active poisoners differ from passive poisoners?
Correct
Active poison is initiated by the poisoner. while passive poison is initiated by the victim. There are two basic methods that cause passive poisoners to activate their poison. For one type of passive poisoner, the poison is activated when the victim makescontact with the passive poisoner. For the other types, the poison is activated when the victim consumes, or ingests, the passive poisoner. It is for a plant or an animal to be passive poisoners. Puffer fish is a type of passive poisoner that must be ingestedto be poisonous.
سم فعال توسط مسموم کننده آغاز می شود. در حالی که سم غیر فعال توسط قربانی آغاز می شود. دو روش اساسی که باعث می شود مسموم کننده های غیر فعال سم خود را فعال کنند به شرح زیر می باشد: یک نوع از مسموم کننده های غیر فعال هنگامی سم خود را سم فعال می کند که قربانی تماس با مسموم کننده غیرفعال برقرار کند. انواع دیگر هنگامی که قربانی مسموم کننده منفعل را مصرف می کند یا آن را قورت دهد. یک گیاه یا حیوان می تواند مسموم کننده غیر فعال باشد. ماهی پفی نوعی مسموم کننده غیرفعال است که باید قورت داده شود تا سم آن فعال شود.

Lecture 3
How long has Morse Code been around?
Correct
Morse Code has been around for more than a century and a half. Samuel Morse developed it in 1838. It used dots and dashes to show the letters. Because E is used more frequently than J, the sign for E in Morse code is shorter than the sign for J. The student homework assignment was to understand some words written in Morse Code.
کد مورس بیش از یک قرن و نیممورد استفاده قرار گرفته است.. ساموئل مورس آن را در سال 1838 توسعه داد. از نقطه و خطوط کرد برای نشان دادن حروف استفاده کرد. از آنجا که E بیشتر از J استفاده می شود، علامت E در مورس کوتاه تر از علامت J است. تکالیف دانش آموزان این بود تا بعضی کلمات را که به زبان مورس نوشته شده بفهمند. برای مثال برای کلمه pay چون a زیاد استفاده می شود از دو نقطهولی برای p و y چون کمتر استفاده می شود از سه نقطه استفاده می شود.

Lecture 4
What misconception did the Greek have about Europe and Asia?
Correct
Greeks named Europe and Asia; however, the Greek had a misconceptions about them whether they were one landmass or two. it is interesting that a German mapmakerapplied the name of America to the North American and Southern American continents.
The names of Arctic and Antarctica are also interesting. Both of them have names based on “bears” and their names were derived from Greek. Ifri were a group of people who lived on the Mediterranean coast of a land called Ifrikiya. Over time, the name evolved into Africa. Australiawas given a Latin name by Europeans:Terra Australia, which actually means “land of the south.”

Lecture 5
1. When did the earthquakes that the students were discussing occur?
Correct
Early in the nineteenth century big earthquakes occurred on the North American continent. The quakes were centered in the state of Missouri, in the Mississippi River valley. It occurred over three months. They were the most powerful earthquakes ever recorded in North America. As a result of the Mississippi earthquakes, some topographic changes occurred: The land sank and new lakes formed, including Reelfoot Lake in Tennessee.
Most earthquakes are explained by plate tecnic theory; however, 5 percent of the earthquakes occur in the middle of large plates, so 5 percent of them are not explained by the theory of plate tectonics. These earthquakes are called intraplate earthquakes. The Mississippi earthquakes are intraplate earthquakes because they occurred in the middle of a tectonic plate.

Lecture 6
1. Why did scientists used to believe that little life was possible at the bottom of the ocean? (2 answers)
Correct
For a long time, scientists used to believe that there was little or no life at the bottom of the ocean because of the lack of temperature and the lack of sunlight. But now they know that there’s a tremendous amount of life at the bottom of the ocean, sometimes as much as four miles down. It’s hard to believe that the ocean can be four miles deep.
life is able to exist on the bottom of the ocean because the black smokers, which look like volcanoes, heat up the water so that it’s not too cold. So, giant worms and giant shellfish are found at the bottom of the ocean but not little sharks. The life in the depths of the ocean is dependent on chemosynthesis rather than photosynthesis. So it’s dependent on chemicals rather than light.
دانشمندان مدت طولانی اعتقاد داشتند که امکان حیات در کف اقیانوس به دلیل عدم وجود درجه حرارت و نور خورشید وجود ندارد. اما اکنون آنها می دانند که در کف اقیانوس زندگی وجود دارد، گاهی اوقات اقیانوس حدود چهار مایل عمق دارد. باور اینکه یک اقیانوس می تواند چهار مایل عمیق باشد.دشوار است.
زندگی می تواند در کف اقیانوس وجود داشته باشد، زیرا سیگاری های سیگاری که آتشفشان شبیه هستند، آب را گرم می کنند، به طوری که آب دیگر خیلی سرد نیست. بنابراین، کرم های غول پیکر و ماهی های غول پیکر در کف اقیانوس ها یافت می شوند، اما کوسه های کوچک نمی توانند آنجا زیست کنند. . زندگی در عمق اقیانوس به جای فتوسنتز وابسته به شیمی سنتز است. بنابراین به مواد شیمیایی بستگی دارد نه نور.

1. What do archaeologists compare when using cross-dating?
Correct
cross-dating is a method of dating one archaeological area by extending relative dates from another area. Using cross-dating archaeologists compare one culture with known and one culture with unknown date to be sure about the date of another culture in the area and understand the dates of the second culture.
As an example, Archaeologists found two areas of ancient cultural development, one in northern Arizona and the other in southern Arizona. They were able to date the cultural development in the northern area scientifically, but they were unable to date the cultural development in the southern area in the same way. so they used tree-ring dating to determine the dates of the northern culture. so they scientifically determined that the culture existed from 700 to 900 A.D. Archaeologists determined the culture dates of the Southern area from cross-dating because they found pieces of northern pottery in the southern area.
تاریخ گذاری همزمانی روشی برای شناسایی منطقه باستان شناسی است که با تعمیم دادن تاریخ نسبی یک ناحیه به ناحیه دیگر انجام می شود. با با استفاده از تاریخ گذاری همزمانی قدمت یک فرهنگ شناخته شده را با یک فرهنگ ناشناخته مقایسه می کنید تا در مورد تاریخ فرهنگ دیگر اطلاعات کسب کرده و تاریخ فرهنگ دوم را حدس بزنند.
به عنوان مثال، باستان شناسان دو منطقه باستانی ، یکی در شمال آریزونا و دیگری در جنوب آریزونا را بررسی کردند. آنها توانستند به روش علمی توسعه فرهنگی منطقه شمالی را تاریخ گذاری کنند، اما آنها نتوانستند به همان روش توسعه فرهنگی منطقه جنوبی را مشخص کنند. بنابراین، آنها با استفاده از حلقه های درختی توانستند تاریخ فرهنگ شمال را مشخص کنند. آنها به روش علمی موفق شدند اعلام کنند که فرهنگ در آنجا طی سالهای 700 تا 900 وجود داشته است. باستان شناسان توانستند تاریخ فرهنگ منطقه جنوب را با روش تاریخ گذاری همزمانی تعیین کنند، زیرا آنها قطعات سفال مناطق شمالی را در منطقه جنوب کشف کردند

Lecture 8
1. Why were Roman soldiers asked to count the stars in the Big Dipper?
Correct
There were some customs in the Roman Military. For example, Roman soldiers asked to count the stars in the Big Dipper to determine if they could see well at long distances. The star at the bend of the handle of the Big Dipper is called Mizar. Mizar is a binary star. If you look closely, there is a second star called Alcor next to Mizar. Based on this eyesight test, it will be determined whether a soldier would fight as an archer or on the front line. Based on the “survival of the fitness” the soldiers in the physical shape tended to survive in the battle because they were not sent to the front line and they were given less dangerous positions from which to fight. In the next chapter Roman military battles will be discussed.
برخی آداب و رسوم در ارتش روم وجود داشت. به عنوان مثال، از سربازان روم خواسته می شد تا ستاره ها را در Big Dipper بشمارند تا تعیین کنند که آیا می توانند دید خوبی از فواصل دورداشته باشند. ستاره ای که در خم دسته Big Dipper قرار دارد، میزار نامیده می شود. میزار ستاره دوتایی است. اگر به دقت نگاه کنید، ستاره ای با نام Alcor در کنار میزار وجود دارد. بر اساس این تست بینایی ، مشخص می شد که آیا یک سرباز به عنوان تیرانداز مبارزه کند و یا در خط مقدم جبهه مبارزه کند یا. بر اساس “بقای تناسب اندام”، سربازانی که دارای شرایط فیزیکی خوبی بودند، معمولا زنده بمانند؛ زیرا آنها به خط مقدم فرستاده نمی شدند و معمولا پست هایی با درجه خطرپذیری پایین تری با دست می آوردند. در فصل بعدی، جنگهای نظامی روم بحث خواهند شد.

Lecture 9
1. What unit is the class beginning with this lecture?
Correct
This lecture introduces a unit on commercial cheese production. Cheese usually is made from cow’s milk, although many cheeses are made from goat, sheep, and even water buffalo and camel’s milk. But it is not made of Yak’s. White cheese and English tea were boycotted by the American colonists.
Some Bostonians preferred drinking hot water instead of tea to avoid paying taxes on English tea, and this hot water became known as Boston Tea.
To summarize, a series of events explained in the lecture as follows: (1) taxes on cheese by the English, preference of American for yellow cheddar, (2) decision to boycott English products, (3) addition of carrot juice to cheddar, preference of Americans for yellow cheddar, and (4) addition of carrot juice to cheddar.
In the next session, commercial production of soft cheese will be discussed.
این سخنرانی یک واحد تولید پنیر تجاری را معرفی می کند. پنیر معمولا از شیر گاو نهیه می شود، اگر چه از پنیر از شیر بز، گوسفند و حتی بوفالو آبی و شتر هم تهیه می شود.. پنیر سفید و چای انگلیسی توسط استعمارگران آمریکایی تحریم شد. بعضی از ساکنین ایالت بوستون به جای نوشیدن چای نوشیدن آب گرم را ترجیح م دادند تا از پرداخت مالیات برای چای انگلیسی جلوگیری کنند. این آب گرم به عنوان چای بوستون شناخته شد.
به طور خلاصه، یک سری رویدادها در این سخنرانی به شرح زیر بیان شده است است (1) مالیات بر پنیر توسط انگلیسیها، تمایل آمریکایی ها بر استفاده از چدار زرد ، (2) تصمیم به تحریم محصولات انگلیسی، (3) اضافه کردن آب هویج به چدار، تمایل آمریکایی ها به استفاده از چدار زرد، و (4) اضافه کردن آب هویج به چدار.
در جلسه بعدی، تولید تجاری پنیر نرم مورد بحث قرار خواهد گرفت.

Lecture 10
1. Which of the followings were mentioned in the lecture as types of American colonies? (2 answers)
Correct
A colony is a group of people living in a distant land but remaining under the jurisdiction of their native land. For example, corporate and proprietary are types of American colonies.
A royal colony was directly under the control of the King of England but Zero of them began as American royal colonies. A proprietary colony was under the control of an individual, the proprietor. Proprietary colonies tended to become royal company. Corporate colonies were governed under a charter received from the King of England by a company’s stockholders. Next week, we will begin discussing the Northern colonies.
مستعمره گروهی از مردم هستند که در سرزمین دوری زندگی می کنند اما تحت اختیار سرزمین بومی خود قرار دارند. به عنوان مثال، شرکت های بزرگ و اختصاصی انواع مستعمرات آمریکایی هستند.
مستعمره سلطنتی مستقیما تحت کنترل پادشاه انگلستان بود اما هیچ یک از آنها به مستعمرات سلطنتی آمریکا تبدیل نشدند. مستعمره اختصاصی تحت کنترل فردی مالک بود. مستعمرات مستقل تمایل به تبدیل شدن به شرکت سلطنتی را داشتند. مستعمرات شرکتی تحت منشوری که از سوی پادشاه انگلستان اعلام می شد وتوسط سهامداران شرکت اداره می شود. هفته بعد، ما در مورد مستعمره های شمالی بحث خواهیم کرد.

Lecture 11
1. What symptoms do victims of hypothermia exhibit? ( 2 answers)
Correct
Hypothermia occurs when the core body temperature falls below its normal range. Victims of hypothermia suffer from a decreased blood pressure, and below-normal temperature. In a severe case, the victim’s heart stops, the brain ceases to function, and death ensues. |You can see hypothermia in anyone who has been exposed to cold for an extended period of time such as snow Skiers, surfers, and rock climbers.
A less obvious place to look for hypothermia is among the elderly, who can even be affected indoors. There are three basic methods for warming a victim of hypothermia. One method is a bath. Another method is wrapping the patient in warm blankets. Finally, two people can lie as close as possible to the victim until help arrives.

narrator: Listen to a lecture in a music class. The professor is talking about George Gershwin.|
man: Good afternoon, class. Today we’ll continue our discussion of American composers.
The composer we’ll discuss has written a huge volume of works that are extremely well known today. You might not recognize this picture of him, but I’m sure you’ll recognize the titles of some of his pieces. How many of you know “Swanee,” “I Got Rhythm,” Porgy and Bess, “Rhapsody in Blue,” and “An American in Paris”? The composer is George Gershwin. He not only composed scores for musicals, films, and operas, but also concert pieces and piano pieces. This week in the listening lab, you’ll be listening to a selection of his music. Today in class, I’ll give you a brief introduction to George Gershwin.|George Gershwin was born in Brooklyn, New York in 1898. He began writing popular songs with his brother Ira when he was 15 years old. Ira wrote the lyrics, and George wrote the music. Al Jolson’s version of “Swanee” popularized the Gershwin brothers’ first real hit song.
|George and Ira began writing scores for Broadway musicals. Soon Gershwin musicals were a popular event in New York. Some felt that George Gershwin was able to capture in music the essence of New York in the 1920s. Certainly his music captured the hearts of Americans. It has become part of American folk music which is passed on orally from generation to generation. Many people don’t realize how many Gershwin songs they know by heart.|
Gershwin certainly did not limit himself to music for Broadway. Throughout his career, he wrote numerous other kinds of music, and he is well known today for music in a variety of genres. On the board is a list of three famous works of Gershwin’s, each from a different genre.|First, we have the jazz piece “Rhapsody in Blue.”
When Gershwin was 26 years old, he began experimenting with jazz and blues themes in orchestral pieces. “Rhapsody in Blue” is his most successful jazz piano concerto. It is a piece for solo piano and orchestra and has become the most frequently performed orchestral piece by an American. The first performance of this piece featured Gershwin himself on piano.|
After a trip to Europe in 1928, Gershwin tried composing “art music.” The result was the very popular piece, “An American in Paris.” This impressionistic composition lets the listener imagine he is in Paris.
| Finally, Gershwin also tried writing opera. One of the deepest ambitions of his life was to write a truly American opera, and this he did with Porgy and Bess. This opera, the most famous of his four operas, has become part of the worldwide repertory of opera.|
That’s all for today’s lecture. Before next class, your assignment is to go to the listening lab and listen to the selections by Gershwin. I’m sure you’ll find as you listen to George Gershwin’s work in the listening lab that you already know many of his pieces. Now, you’ll know the composer!
