The pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. Pitch is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop.
The most famous version of the experiment was started in 1927 by Professor Thomas Parnell of the University of Queensland in Brisbane, Australia, to demonstrate to students that some substances that appear to be solid are in fact very-high-viscosity fluids. Parnell poured a heated sample of pitch into a sealed funnel and allowed it to settle for three years. In 1930, the seal at the neck of the funnel was cut, allowing the pitch to start flowing. Large droplets form and fall over the period of about a decade.
The eighth drop fell on 28 November 2000, allowing experimenters to calculate that the pitch has a viscosity approximately 230 billion (2.3×1011) times that of water.
The ninth drop is expected to fall in 2013!!

|December 1938||1st drop fell||96–107||8.0–8.9|
|February 1947||2nd drop fell||99||8.3|
|April 1954||3rd drop fell||86||7.2|
|May 1962||4th drop fell||97||8.1|
|August 1970||5th drop fell||99||8.3|
|April 1979||6th drop fell||104||8.7|
|July 1988||7th drop fell||111||9.3|
|28 November 2000||8th drop fell||148||12.3|

IF + SUBJECT + PAST PERFECT, SUBJECT + WOULD + HAVE + PAST PARTICIPLE
SUBJECT + WOULD + HAVE + PAST PARTICIPLE + IF + SUBJECT + PAST PERFECT
The third conditional (also called conditional type 3) is a structure used for talking about unreal situations in the past.
The first conditional and second conditionals talk about the future. With the third conditional we talk about the past. We talk about a condition in the past that did not happen. That is why there is no possibility for this condition.The third conditional is also like a dream, but with no possibility of the dream coming true.
Last week you bought a lottery ticket. But you did not win. :-(
condition result Past Perfect WOULD HAVE + Past Participle If I had won the lottery I would have bought a car.
Notice that we are thinking about an impossible past condition. You did not win the lottery. So the condition was not true, and that particular condition can never be true because it is finished.
We use the past perfect tense to talk about the impossible past condition. We use WOULD HAVE + past participle to talk about the impossible past result.
The important thing about the third conditional is that both the condition and result are impossible now.
Look at some more examples in the tables below:
IF condition result past perfect WOULD HAVE + past participle If I had seen Mary I would have told her. If Tara had been free yesterday I would have invited her. If they had not passed their exam their teacher would have been sad. If it had rained yesterday would you have stayed at home? If it had rained yesterday what would you have done?
result IF condition WOULD HAVE + past participle past perfect I would have told Mary if I had seen her. I would have invited Tara if she had been free yesterday. Their teacher would have been sad if they had not passed their exam. Would you have stayed at home if it had rained yesterday? What would you have done if it had rained yesterday?

«El Día Internacional de la Madre Tierra nos brinda la oportunidad de reafirmar nuestra responsabilidad colectiva de promover la armonía con la naturaleza en un momento en el que nuestro planeta se encuentra amenazado por el cambio climático, la explotación insostenible de los recursos naturales y otros problemas creados por el hombre. Cuando creamos amenazas para nuestro planeta, no solo ponemos en peligro el único hogar que tenemos sino incluso nuestra futura supervivencia. Celebremos este Día Internacional renovando nuestra promesa de honrar y respetar a la Madre Tierra.»
Mensaje del Secretario General, Ban Ki-moon
De un hombre en las Maldivas preocupado por trasladar a su familia ya que el nivel del mar aumenta, a un oso polar en el derretimiento del ártico, el cambio climático tiene muchas caras. Para celebrar el Día Internacional de la Madre Tierra, se han recogido en todo el mundo imágenes de personas, animales y lugares directamente afectados o amenazados por el cambio climático, así como imágenes de personas esforzándose para hacer algo al respecto.
La Madre Tierra es una expresión común utilizada para referirse al planeta Tierra en diversos países y regiones, lo que demuestra la interdependencia existente entre los seres humanos, las demás especies vivas y el planeta que todos habitamos. Por ejemplo, en Bolivia la llaman «Pacha Mama» y nuestros ancestros en Nicaragua se referían a ella como «Tonantzin».
La proclamación del 22 de abril como Día Internacional de la Madre Tierra supone el reconocimiento de que la Tierra y sus ecosistemas nos proporcionan la vida y el sustento a lo largo de nuestra existencia. También supone reconocer la responsabilidad que nos corresponde, como se expone en la Declaración de Río de 1992, de promover la armonía con la naturaleza y la Tierra a fin de alcanzar un justo equilibrio entre las necesidades económicas, sociales y ambientales de las generaciones presentes y futuras.
Reconociendo que la Madre Tierra refleja la interdependencia que existe entre los seres humanos, las demás especies vivas y el planeta que todos habitamos, la Asamblea General declaró el 22 de abril como Día Internacional de la Madre Tierra para destacar la necesidad de ayudar a mejorar las vidas de los niños y los adultos que sufren del desorden para que puedan llevar una vida plena y significativa.
23 April is a symbolic date for world literature for on this date in 1616, Cervantes, Shakespeare and Garcilaso de la Vega all died. It is also the date of birth or death of other prominent authors such as Maurice Druon, Haldor K.Laxness, Vladimir Nabokov, Josep Pla and Manuel Mejía Vallejo.
- Sleep well:
Go to bed early the day before the exam and get a good night’s sleep.
Have a healthy breakfast and avoid sugary snacks, because they will make you tired later on.
Pack your bag carefully:
You need a sharp pencil and an eraser for the exam. You should also take some spare pencils and a pencil sharpener.
Arrive early at the exam centre:
Leave your house early so you don’t need to worry about being late.
Always read the questions:
Reading the questions will tell you useful information that will help you understand the situations.
It’s OK to write on the question paper. You can underline parts of the reading text, or write things down while you listen.
Use your time well:
If you can not answer a question, move on and come back to it later. You shouldn’t spend all your time on one question. You need to answer as many questions as you can.
Check your answers:
After you finish, look back and check your answers. Make sure you have answered all the questions and check your spelling.
Answer all the questions:
Don’t leave any answers blank. If you’re not sure of the answer, guess!
Try to relax!:
Remember that you have studied hard and now you are ready for the exam.
