The Disappearing Honeybee
- Honeybees do more than just make honey. They fly around and pollinate flowers, plants, and trees. Our fruits, nuts, and vegetables rely.....................these pollinators. One third.....................America’s food supply is pollinated.....................the honeybee.
Have you seen or heard a honeybee lately? Bees are mysteriously disappearing in many parts of the world. Most people don’t know about this problem. It is called “colony collapse disorder” (CCD). Some North American beekeepers lost 80% of their hives from 2006-2008. Bees in Italy and Australia are disappearing too.
The disappearance of the honeybee is a serious problem. Can you imagine never eating another blueberry? What about almonds and cherries? Without honeybees food prices will skyrocket. The poorest people always suffer the worst when there is a lack of food.
This problem affects other foods besides fresh produce. Imagine losing your favourite ice cream! Haagen Daaz is a famous ice cream company. Many of their flavours rely on the hard working honeybee. In 2008, Haagen Daaz began raising money for CCD. They also funded a garden at the University of California called The Haven. This garden helps raise awareness about the disappearing honeybee and teaches visitors how to plant for pollinators.
Donating money to research is the most important thing humans can do to save the honeybee. Some scientists blame CCD on climate change. Others think pesticides are killing the bees. Commercial bee migration may also cause CCD. Beekeepers transport their hives from place to place in order to pollinate plants year round.

Analyze the sentences below about ‘Reading Comprehension Strategies’.
1. Skimming is one of the strategies that you have to make inferences about the text to find the correct answers.
2. Making predictions is a reading comprehension strategy in which the reader uses information from a text (including titles, headings, pictures, and diagrams) and his/her own personal experience to anticipate what the text is about .
3. If you want to read a text rapidly in order to find specific facts, you are using the Scanning Strategy.
Choose the alternative which contains all the correct affirmatives:
In order for collection of sentences and utterances to succed effectively, the discourse needs to be organised or conducted in such a way that it will be successful. In written English this calls for both coherence and cohesion. For a text to be coherent, it needs to be in the right order. (…)
No matter how coherent a text is, however, it will not work unless it has internal cohesion. The elements in that text must cohere or stick to each other successfully to help us navigate our way around the stretch of discourse. One way of achieving this is through lexical cohesion, and a way of ensuring lexical cohesion is through the repetition of words and phrases. (…) We can also use interrelated words and meanings to bind a text together (…)
Another similar cohesive technique is that of substitution, using a phrase to refer to something we have already written. (…) Writers also use linkers such as and, also, moreover (…)
These features are also present in spoken language, which also shows many examples of ellipsis (where words from a written-grammar version of an utterance are left out without compromising the meaning of what is said). (…)

There is a danger in paying too much attention to learners’ errors. While errors indeed reveal a system at work, the classroom language teacher can become so preoccupied ________ noticing errors that the correct utterances in the second language go unnoticed. In our observation and analysis of errors – for all that they do reveal about the learner – we must beware of placing too much attention on errors and not lose sight of the value of positive reinforcement of clearly expressed language that is a product of the learner’s progress of development. While the diminishing of errors is an important criterion ______ increasing language proficiency, the ultimate goal of second language learning is the attainment of communicative fluency.
Another inadequacy in error analysis is an overemphasis on production data. Language is speaking and listening, writing and reading. The comprehension of language is as important as production. It so happens that production lends itself to analysis and thus becomes the prey of researchers, __________ comprehension data is equally important in developing an understanding of the process of SLA.

Classes which are arranged in a circle make quite a strong statement about what the teacher and the students believe in. With all the people in the room sitting in a circle, there is a far greater feeling of equality than when the teacher stays out at the front. This may not be quite so true of the horseshoe shape, where the teacher is often located in a commanding position, but, even here, the rigidity that comes with orderly rows, for example, is lessened.
With the horseshoe and circle seating, the classroom is a more intimate place and the potential for students to share feelings and information through talking, eye contact or expressive body movements (eyebrow-raising, shouldershrugging, etc.) is far greater than when they are sitting in rows.

1. What is an analog-digital converter?
An Analog-Digital Converter (ADC) is a widely used electronic component that converts an analog electric signal (usually a voltage) into a digital representation. The ADCs are at the front-end of any digital circuit that needs to process signals coming from the exterior world. Its schematic symbol is:
The output of a microphone, the voltage at a photodiode or the signal of an accelerometer are examples of analog values that need to be converted so that a microprocessor can work with them.
2. How does the ADC convert a signal?
Many ways have been developed to convert an analog signal, each with its strengths and weaknesses. The choice of the ADC for a given application is usually defined by the requirements you have: if you need speed, use a fast ADC; if you need precision, use an accurate ADC; if you are constrained in space, use a compact ADC.
All ADCs work under the same principle: they need to convert a signal to a certain number of bits N. The sequence of bits represents the number and each bit has the double of the weight of the next, starting from the Most Significant Bit (MSB) up to the Least Significant Bit (LSB). In a nutshell, we want to find the sequence of bits bN−1, bN−2, ..., b0 that represents the analog value Vin as Vin=∑n=0N−1bn2nVref2N.
