The first diagram indicates the stages and equipment in the process of making cement, and the cond one illustrates how cement and other materials are mixed to produce concrete for building purpos.
Cement production involves the following steps. The first step is to put limestone and clay on two different conveyors. Then, the two types of materials are presd into the crusher which breaks them into powder. After that, the powder is poured into a mixer, and then mixtures are transmitted into a rotating heater which works with heat. The following step is that a band carrier leads the heated powder to a grinder where the cement comes out. Finally, cement is packed into bags,and the process is finished.
Concrete production is much more simple. Four different kinds of materials are needed in different prop
ortion. Gravel accounts for the largest part, at 50%, followed by sand, which is 25%. Cement and water contributes 15% and 10% respectively. The four materials are then mixed and poured into a concrete mixer and after a period of whirling, concrete is produced.
In conclusion, making cement has more complex process than making concrete though concrete needs more materials than cement.

The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.
Summari the information by lecting and reporting the main features, and make comparisons where relevant.
The first diagram shows that there are four main stages in the life of the silkworm. First of all, eggs are produced by the moth and it takes ten days for each egg to become a silkworm larva that feeds on mulberry leaves. This stage lasts for up to six weeks until the larva produces a cocoon of silk thread around itlf. After a period of about three weeks, the adult moths eventually emerge from the cocoons and the life cycle begins again.pets3口试
The cocoons are the raw material ud for the production of silk cloth. Once lected, they are boiled in water and the threads can be parated in the unwinding stage. Each thread is between 300 and 900 metres long, which means they can be twisted together, dyed and then ud to produce cloth in the weaving stage.
Overall, the diagrams show that the cocoon stage of the silkworm can be ud to produce silk cloth through a very simple process.black lives matter

Summari the information by lecting and reporting the mainfeatures and make comparisons where relevant.
The diagram shows how chewing gum is produced. Firstly the ingredients of gum are put into a container and was heated until they form a single mass. This is then strained until all of the liquid has been eliminated. Next, the gum is pasd into another container/place and the desired flavorings, sweeteners and softeners are added This mixture is blended until all of the ingredients are mixed together. The gum then
travels/pass to a different machine which us rollers to flatten out the gum. Finally the thin sheets of gum are cut into rectangular shapespptp
and broken into parate pieces then the gum pass / travels along a conveyor belt where it is enclod in packaging ready for distribution.四
The diagram below shows how fruit is canned.
Summari the information by lecting and reporting the main features and make comparisons where relevant.
The diagram shows the process of canning fresh fruit. First the fruit is picked from trees by hand. It is then transported to the cannery by large trucks. At the cannery the fruit is washed and quality checked, and any poor quality fruit is rejected. The good quality fruit is put into cold storage. When it is ready for canning the fruit is weighed and graded. The grading ensures that fruit of a similar size is kept together. After this the fruit is peeled and the cores are removed. It is then sliced into the required sizes and put into cans. Juice or syrup is also added to the cans. Once the cans have been filled, they are aled and cooked over heat to ensure that the cans are sterilized. When the cans are cool, labels are attached and they are placed into storages. The canned fruit is now ready to be
despatched to supermarkets and sold.

The diagram below shows the process of making chocolate.
Summari the information by lecting and reporting the main features and make comparisons where relevant.
Chocolate's varied flavours, colours, shapes and textures result from different recipe traditions. Which have evolved in different parts of the world. The esntial ingredient in all chocolate is cocoa, which is made from the cream-coloured beans that grow in pods on the cacao tree. The cacao tree, which grows in equatorial regions such as South America,
Africa and Indonesia produces a fruit about the size of a small pineapple, Inside which are the tree's eds.
After harvesting, the cocoa beans arc removed from the pods and piled in heaps that are left for veral days to dry. The dried beans are then transported to factories where they are sorted and roasted. The shells are then removed and the beans are ground into chocolate liquor - a thick brown mp3 lrc
liquid which forms a solid at about room temperature. This liquor contains a high percentage of fat cocoa butter, which is removed by using press. The solid block of cocoa that remains is then made into a powder which can be ud to make a hot chocolate drink, or is mixed back with some of the cocoa butter, sugar and other flavour such as vanilla to make the different kinds of chocolate.

The process by which bricks are manufactured for the building industry can be outlined in ven concutive steps.
First the raw material, clay, which lies just below the surface of soil in certain clay-rich areas has to be dug up by a digger.
Then the lumps of clay are placed on a metal grid, in order to break up the big chunks of clay into much smaller ones, which fall through the metal grid onto a roller, who motion further gregates t
he bits of clay. Sand and water are added to make a homogenous mixture, which is then either formed in moulds or cut into brick-shaped pieces by means of a wire cutter.
The fresh bricks are then kept in a drying oven for at least 24 and a maximum of 48 hours, veral dozens if not hundreds of bricks at a time. The dried bricks are then transferred to a also-called kiln, another type of high temperature of 200℃- 980℃, then at a high temperature of 870℃- 1300℃. This process is followed by cooling down the finished bricks for 48 to 72 hours in a cooling chamber.
Once the bricks have been cooled down and have become hard, they get packaged and delivered to their final destination, be it a building site or storage.

The diagrams below show the process of how uranium is ud in the production of nuclear power.

This diagram describes how uranium is mined, procesd, ud and then discarded.
北京主持人培训
Uranium is found under the ground and so it must be mined. Once the mined uranium has been extracted, it is taken to a processing centre. Here the uranium is converted into a form that can be ud as a fuel in a nuclear power station. To do this, the uranium is changed into a gas and enriched before it is reformed as U-235 fuel pellets.
The fuel pellets are then ud in nuclear power stations to provide up to 7 billion kilowatts of electricity from just one station. After the fuel has been ud for about four years it is removed from the power station and stored. Some of the ud fuel can be re-procesd and re-ud in a power station to produce more electricity.
