Trampolining

What’s more fun than standing still? Jumping up and down on a springy piece of fabric (織物)! This activity is known as trampolining and it’s sweeping the nation．

The idea of trampolining is ancient．Eskimos have been throwing each other in the air for thousands of years．Firemen began using a life net to catch people jumping from buildings in 1887.1.

A gymnast named George Nissan and his coach Larry Griswold made the first modern trampoline in 1936.They got the idea by watching swing artists bouncing off of a tight net at the circus．They named their equipment after the Spanish word trampolín, which means diving board.

2. In 1942 they began making trampolines to sell to the public.

3.Experts find that more than 100,000 people hurt themselves while using one each year．Clubs and gyms use large safety nets or other equipment to make it safer．Most trampoline injuries happen at home．Since trampolines are more affordable than ever, injuries are even more common.

These injuries happen for many reasons．People may bounce too high and land off of the trampoline or onto the springs．4.Perhaps the worst injuries happen when untrained people try to do flips (快速翻轉(zhuǎn))．Landing on your neck or head can cause injuries or even kill you.

But don’t let all that bad news keep you down．There are many things that you can do to practice safe trampolining．Trampolines have been around for a while now．They have brought a lot of joy to many people．They can be a good source of exercise and activity．5.But they can also be deadly．It is important to follow some professional guidance．Be sure that you are practicing safety while having a good time．Happy bouncing!

A． They can help people improve their balance and moves.

B． Trampolines may be fun, but they can also be dangerous.

C． The men wanted to share their idea with the whole world.

D． Injuries also happen when many people are jumping at the same time.

E． You can surround your trampoline with a net so that people don’t fall off of it．

F． They found a winner when they performed a piece of spring across a steel frame.

This was Larry’s another underwater expeditions(探險(xiǎn)). However, this time, it was quite different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.

Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.

After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.

Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different spots for free. Larry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.

Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than Lorry had been then. This was the key to a successful underwater expedition.

1.In what way was this expedition different for Larry?

A. His daughter had grown up.

B. He had become a famous diver.

C. His daughter would dive with him.

D. His father would dive with him.

2.What can be inferred from Paragraph2?

A. Larry was lucky to have got such a chance to dive.

B. Larry liked the rented diving suits.

C. Ten-year-old children were permitted to dive.

D. Divers had to buy diving equipment.

3.Why did Larry have to stay in a cage underwater sometimes?

A. To take photos more conveniently.

B. To dive into the deep water.

C. To admire the underwater view.

D. To protect himself from danger.

4. What can be learned from the underlined sentence?

A. Larry didn’t wear a watch.

B. Larry enjoyed the adventure.

C. Larry had a poor memory.

D. Larry was not good at math.

5.What did Larry expect his daughter to do?

A. Make a good diving guide.

B. Have longer hours of training.

C. Take a lot of photo underwater.

D. Become a successful diver.

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death．Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage．The organism can still be revived(復(fù)活)．Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues．Death is then unchangeable and final．
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs．The best method developed so far involves cooling of the organism, combined with narcotic sleep．By slowing down the body’s metabolism(新陳代謝), cooling delays the processes leading to biological death．
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta． The scientist put Keta to sleep with a narcotic． Then they surrounded her body with ice-bags and began checking her body temperature．When it had dropped to 28 degrees the scientists began draining blood from an artery．The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in．For twenty minutes Keta remained in this state．Her temperature dropped to 22 degrees．At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing．After two minutes Keta’s heart became active once more．After fifteen minutes, spontaneous(自發(fā)的)breathing began, and after four hours Keta opened her eyes and lifted her head． After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room．Her behavior differed little from that of a healthy animal．
1.For a person who suffers from the clinical death, _________．
A． his most important organs are damaged．
B． he still has the possibility of getting back to life．
C． he can not avoid final death．
D． he is still very much alive
2.Scientists try to make the time of clinical death longer in order to __________．
A． slow down the body’s metabolism．
B． bring vital cells and tissues back to active life．
C． cool the organism．
D． delay the coming of biological death．
3. How did the scientists put Keta into clinical death?
A． By putting her to sleep, lowering her temperature and draining her blooD．
B． By surrounding her body with ice-bags and draining her blood．
C． By lowing her blood pressure and stopping her heart from beating．
D． By draining her blood, lowering her blood pressure and stopping her breathing．
4. All of the following indicate that the monkey has almost restored to her original physical state except the fact that__________．
A． her heart beat again．
B． she regained her normal breath．
C． she rejected a penicillin injection．
D． she acted as lively as a healthy monkey．

Directions：Read the following three passages．Each passage is followed by several questions or unfinished statements．For each of them there are four choices marked A, B, C and D．Choose the one that fits best according to the information given in the passage you have just read.

LT123 Workshops

‘I’m pleased to say that 2015 is our third year sponsoring the IATEFL information desk．This year, we are running three workshops covering some of the key areas of our wide-ranging special skills: testing, editing and vocabulary．We how to see you.’

—— Russell Whitehead Director

Vocabulary testing: why, what and how? By Felicity O’ Dell & Russell Whitehead
Saturday 11th April 3:50-4:35 pm Charter 4
Should vocabulary be one of the language features that we test and, if so, why? What vocabulary - and what aspects of vocabulary - should we focus on in our tests? What methods can we use to test vocabulary?
We will discuss answers to these questions, considering the strengths and weaknesses of different types of vocabulary test for different teaching contexts.
There’s something missing from your project - the editor! By David Baker & Fiona MacKenzie
Sunday 12 April 10:25-11:10 am Charter 8
Big publishing companies no longer offer the single route to publication．Whether you are self-publishing, a teaching institution developing its own materials, or a digital start-up, in a highly competitive environment it isn’t enough to write something and just put it out there.
Quality still matters - you can’t afford to forget one of the key roles in successful publishing.
Vocabulary levels: which words are at which level? By Stephen Bullon
Monday 13th April 1:35-2:20 pm Charter 8
While students develop their competence in the four skills and in their ability to master grammatical structures, they are together building their vocabulary.
We will try to establish the standards involved in selecting appropriate vocabulary at the various levels students pass through: frequency, teaching requirements, and register are all factors that need to be weighed in the balance.
LT123 is the new name for Language Testing 123, and we are proud sponsors of the 49th Annual
International IATEFL Conference and Exhibition.
Manchester, April 2015.

The Entropia Universe

The Entropia Universe is a virtual world on the Internet, which seems very like our real life．It is set in a distant future and based on a planet called Calypso．Entropia was the brainchild of a group of Swedish computer lovers who decided to see if they could create a three dimensional (維度的) virtual world that could be placed on the Internet．They did manage after they received the financial backing they needed．

The game can be played for free, but nearly all in-game activities require personal resources that you have available to use．Although there are various activities to keep you busy on Calypso, what most people do first is to find themselves a profession, such as hunting the fierce animals on Calypso, mining the precious minerals and making tools．Then they can think about buying their virtual house or paying a visit to a virtual nightclub or doing any of the other activities that make life bearable．

Entropia has its very own economy (經(jīng)濟(jì)) and its own currency, the PED (Project Entropia Dollars)．Players move real world money into PED which they then use to pay for their life on Calypso．However, the virtual things inside Entropia do have a real value in the outside world, and careful business deals mean that players can actually make real money there．PED can be changed into dollars any time at a rate of 10PED to 1US$．

What’s so impressive about The Entropia Universe is the number of players; currently more than 600,000 representing over 220 countries from planet Earth．A number of players insist that it’s a good way to make money．However, the reality of Entropia’s economic system is that most people end up paying more than they earn and it’s not uncommon to find players who are paying up to $200 a month into their PED account．This might not be the most economical way of spending one’s free time．However, some people say that for them the fact that they can escape the realities of the earthbound life and become a different person with a completely different life for a few hours every week is worth the use of money, even if they don’t get any interest rates on it．

1.What can we learn about The Entropia Universe?

A． It costs nothing to join．

B． It focuses on business plans．

C． It is designed for computer lovers．

D． It presents what life is like on other planets．

2.What does Paragraph 2 mainly talk about?

A． What people do on Calypso．

B． When people buy houses there．

C． How people make life bearable．

D． Why people often find a job first．

3.According to the author, playing on The Entropia Universe ______．

A． may be very annoying

B． can be quite expensive

C． is a cheap way to kill time

D． is a good way to earn money

4.What can be inferred about The Entropia Universe?

A． It is technical．

B． It is satisfying．

C． It is ridiculous．

D． It is educational．
