Set 2 General Training book, Practice Test 7

Writing Task 2

You should spend about 40 minutes on this task.

Write about the following topic:

Some of today’s schools insist that all students have their own laptop computer in class to assist in their education.

Do you feel that this would be an advantage to students’ education or would it be an unnecessary complication?

Give reasons for your answer and include any relevant examples from your knowledge or experience.

You should write at least 250 words.

Several schools around the world insist that all students should bring their own private laptop to class to assist in their education. Technology has become a significant component of educating children and is considered beneficial in many ways. Nonetheless, there are likewise many disadvantages to using private technological equipment in classrooms.

Bringing a private laptop to class offers a variety of benefits for students. Firstly, laptops can be used to take notes in classes where teachers sometimes speak at a high speed. Many children find that they can type faster than they can write by hand and therefore prefer typing their notes in class so as to not miss any important information. Teachers could furthermore make use of learning programs and websites during class, as students would have the possibility of using these websites on their private laptops. Moreover, students can use periods meant for working on assignments effectively, because they can work on their assignments digitally right away and not have to type up handmade notes later on. Information can additionally be distributed more easily to students, as for example hand-outs can simply be emailed or shared electronically and do not have to be printed.

Although bringing private laptops to class offers these various advantages, it also creates several disadvantages. Laptops firstly are fairly expensive, meaning that families with more than one child will have to spend a large amount of money to purchase laptops for all their children. Furthermore, laptops can easily be damaged during class and outside of class as well as stolen, which could create future costs for families. During class laptops can also distract students, because they can surf the Internet or look at non-class-related work during class periods. The amount of time students are exposed to technological equipment is also increased by incorporating laptops into classrooms, which can result in several health-related problems.

In conclusion, bringing a private laptop to class involves several advantages and disadvantages. Nonetheless, I personally believe that if used wisely, a laptop is an extremely useful tool in lessons and therefore I would support this initiative.

5 thoughts on “IELTS Band 9 essay, topic: Some schools insist that students have laptops in class (advantages / disadvantages)”

How can I improve my writing skills.I really do not have many ideas regarding environment, technology, science and other things that we mostly have to write in IELTS easy topics.Can you guide me what is the best way to improve my writing skills?How can I merge different ideas in whole easy.And how can I think more about things smoothly and write it immediately.

It seems as though lack of ideas and vocabulary for those ideas is the main issue, the reason why it is hard for you to write. Reading high-scoring essays on these problematic topics should help with both ideas and expressions to use in your own essays. I recommend starting with a list of topics that you would consider hard, and writing just essay plans for them. An essay plan can consist of just 4-5 items – what would you talk about in the introduction? in the 1st body paragraph? the 2nd body paragraph? and so on. If you can write a plan, that means you have enough ideas to talk about. Then you need to check if you have the appropriate vocabulary, and if you don’t – research it. I hope this help!

In this modern world, many educational institutes emphasise students use their own laptops during the study. However, it is caused a burden on the students. To my opinion in this matter is that there are various benefits for students of holding a laptop while taking classes.

Students should bring their electronic devices to the lectures because they become familiar and used to with these technologies. For example, some students follow the instructions of the professor when they are attending lectures. This could make it more convenient to use and understand. Furthermore, some class activities require networking devices for doing experiments. If a learner has access to gadgets, they could do some experiments and analyze the results. Hence, the learning process of the student could be faster and adoptable. There are some other advantages of carrying a laptop in the university, such as working on different projects and assignments. In other words, many students utilize their free time to work on paid projects to expand their knowledge. Similarly, they also work on class assignments while they are free lectures during study hours. The most important point is that students can save time if the library laptop is occupied. Thus students have the independency of whether to work on the previous lecture or continue to work on the last project. I am convinced that using their laptop in class has significant positive points.

To conclude, many universities are forced to buy laptops for class work; however, it has many justifications. Considering the benefits, I personally believe that using computers during lectures definitely assists learners in following tutors’ instructions.

I guess it is 6 or maximum 6.5 essay

I’d be really interested to find out how you can substantiate your claim. What are you basing your analysis on?

Solar Storm Intensifies, Filling Skies With Northern Lights

Officials warned of potential blackouts or interference with navigation and communication systems this weekend, as well as auroras as far south as Southern California or Texas.

By Katrina Miller and Judson Jones

Katrina Miller reports on space and astronomy and Judson Jones is a meteorologist.

A dramatic blast from the sun set off the highest-level geomagnetic storm in Earth’s atmosphere on Friday that is expected to make the northern lights visible as far south as Florida and Southern California and could interfere with power grids, communications and navigations system.

It is the strongest such storm to reach Earth since Halloween of 2003. That one was strong enough to create power outages in Sweden and damage transformers in South Africa.

The effects could continue through the weekend as a steady stream of emissions from the sun continues to bombard the planet’s magnetic field.

The solar activity is so powerful that the National Oceanic and Atmospheric Administration, which monitors space weather, issued an unusual storm watch for the first time in 19 years, which was then upgraded to a warning. The agency began observing outbursts on the sun’s surface on Wednesday, with at least five heading in the direction of Earth.

“What we’re expecting over the next couple of days should be more significant than what we’ve seen certainly so far,” Mike Bettwy, the operations chief at NOAA’s Space Weather Prediction Center, said at a news conference on Friday morning.

For people in many places, the most visible part of the storm will be the northern lights, known also as auroras. But authorities and companies will also be on the lookout for the event’s effects on infrastructure, like global positioning systems, radio communications and even electrical power.

While the northern lights are most often seen in higher latitudes closer to the North Pole, people in many more parts of the world are already getting a show this weekend that could last through the early part of next week.

As Friday turned to Saturday in Europe, people across the continent described skies hued in a mottling of colors.

Alfredo Carpineti , an astrophysicist, journalist and author in North London, saw them with his husband from the rooftop of their apartment building.

“It is incredible to be able to see the aurora directly from one’s own backyard,” he said. “I was hoping to maybe catch a glimpse of green on the horizon, but it was all across the sky in both green and purple.”

Here’s what you need to know about this weekend’s solar event.

How will the storm affect people on Earth?

A geomagnetic storm watch or warning indicates that space weather may affect critical infrastructure on or orbiting near Earth. It may introduce additional current into systems, which could damage pipelines, railroad tracks and power lines.

According to Joe Llama, an astronomer at Lowell Observatory, communications that rely on high frequency radio waves, such as ham radio and commercial aviation , are most likely to suffer. That means it is unlikely that your cellphone or car radio, which depend on much higher frequency radio waves, will conk out.

Still, it is possible for blackouts to occur. As with any power outage, you can prepare by keeping your devices charged and having access to backup batteries, generators and radio.

The most notable solar storm recorded in history occurred in 1859. Known as the Carrington Event, it lasted for nearly a week, creating aurora that stretched down to Hawaii and Central America and impacting hundreds of thousands of miles of telegraph lines.

But that was technology of the 19th century, used before scientists fully understood how solar activity disrupted Earth’s atmosphere and communication systems.

“That was an extreme level event,” said Shawn Dahl, a forecaster at NOAA’s Space Weather Prediction Center. “We are not anticipating that.”

Unlike tornado watches and warnings, the target audience for NOAA’s announcements is not the public.

“For most people here on planet Earth, they won’t have to do anything,” said Rob Steenburgh, a space scientist at NOAA’s Space Weather Prediction Center.

The goal of the announcements is to give agencies and companies that operate this infrastructure time to put protection measures in place to mitigate any effects.

“If everything is working like it should, the grid will be stable and they’ll be able to go about their daily lives,” Mr. Steenburgh said.

Will I be able to see the northern lights?

It is possible that the northern lights may grace the skies this week over places that don’t usually see them. The best visibility is outside the bright lights of cities.

Clouds or stormy weather could pose a problem in some places. But if the skies are clear, even well south of where the aurora is forecast to take place, snap a picture or record a video with your cellphone. The sensor on the camera is more sensitive to the wavelengths produced by the aurora and may produce an image you can’t see with the naked eye.

Another opportunity could be viewing sunspots during the daytime, if your skies are clear. As always, do not look directly at the sun without protection. But if you still have your eclipse glasses lying around from the April 8 event, you may try to use them to try to spot the cluster of sunspots causing the activity.

How strong is the current geomagnetic storm?

Giant explosions on the surface of the sun, known as coronal mass ejections, send streams of energetic particles into space. But the sun is large, and such outbursts may not cross our planet as it travels around the star. But when these particles create a disturbance in Earth’s magnetic field, it is known as a geomagnetic storm.

NOAA classifies these storms on a “G” scale of 1 to 5, with G1 being minor and G5 being extreme. The most extreme storms can cause widespread blackouts and damage to infrastructure on Earth. Satellites may also have trouble orienting themselves or sending or receiving information during these events.

The current storm is classified as G5, or “extreme.” It is caused by a cluster of sunspots — dark, cool regions on the solar surface — that is about 16 times the diameter of Earth. The cluster is flaring and ejecting material every six to 12 hours.

“We anticipate that we’re going to get one shock after another through the weekend,” said Brent Gordon, chief of the space weather services branch at NOAA’s Space Weather Prediction Center.

Why is this happening now?

The sun’s activity ebbs and flows on an 11-year cycle, and right now, it is approaching a solar maximum. Three other severe geomagnetic storms have been observed so far in the current activity cycle, which began in December 2019, but none were predicted to cause effects strong enough on Earth to warrant a watch or warning announcement.

The cluster of sunspots generating the current storm is the largest seen in this solar cycle, NOAA officials said. They added that the activity in this cycle has outperformed initial predictions .

More flares and expulsions from this cluster are expected, but because of the sun’s rotation the cluster will be oriented in a position less likely to affect Earth. In the coming weeks, the sunspots may appear again on the left side of the sun, but it is difficult for scientists to predict whether this will cause another bout of activity.

“Usually, these don’t come around packing as much of a punch as they did originally,” Mr. Dahl said. “But time will tell on that.”

Jonathan O’Callaghan contributed reporting from London.

An earlier version of this article misstated the radio frequencies used by cellphones and car radios. They are higher frequencies, not low.

Title: on the effect of geometry on scaling laws for a class of martensitic phase transformations.

Abstract: We study scaling laws for singular perturbation problems associated with a class of two-dimensional martensitic phase transformations and deduce a domain dependence of the scaling law in the singular perturbation parameter. In these settings the respective scaling laws give rise to a selection principle for specific, highly symmetric domain geometries for the associated nucleation microstructure. More precisely, firstly, we prove a general lower bound estimate illustrating that in settings in which the domain and well geometry are incompatible in the sense of the Hadamard-jump condition, then necessarily at least logarithmic losses in the singular perturbation parameter occur in the associated scaling laws. Secondly, for specific phase transformations in two-dimensional settings we prove that this gives rise to a dichotomy involving logarithmic losses in the scaling law for generic domains and optimal linear scaling laws for very specific, highly compatible polygonal domains. In these situations the scaling law thus gives important insight into optimal isoperimetric domains. We discuss both the geometrically linearized and nonlinear settings.

The book has been designed around seven broad themes, i.e. Food, Materials, The World of the Living, How Things Work, Moving Things, People and Ideas, Natural Phenomenon and Natural Resources. The Physics, chemistry and biology disciplines are not separately defined in Class 9 Science; instead, they have been provided in the form of chapters.

The best way to study Science is to read a particular topic before it is taught in class. Then during the class, they should listen carefully to what the teacher is explaining. This will clear all their doubts and make the concepts more clear. Next, they should answer the questions that are provided at the end of each chapter. In case they cannot find the answer to any question, they must refer to the NCERT Solutions of Class 9. We have also provided the weightage of each unit of Science in the table below.

Sponge is solid, but we can still compress it, why?

A sponge is solid, but we can still compress it because the sponge contains tiny pores in it that are filled with air. Hence, when a sponge is pressed, the air filled in these pores would be expelled from the holes making it highly compressible.

Thanks BYJU’s
