Only thus ________ finish the task ahead of time.
[ ]
A technique that controls immediate gas explosions by spraying them with large droplets of water is being tested by scientists at the University of Wales, United Kingdom．Instead of using the traditional fine water sprays when a gas leak is detected, the researchers have discovered that large droplets help to draw in some of the force of any explosion and provide a better way of controlling fire．
The research is based on studies made of the Piper Alpha oil rig （油井） explosion that occurred in the North Sea nine years ago killing 167 workers．The Welsh team found that by covering the gas-leak area with water droplets, the explosion and its effect can be greatly reduced．
Dr Gerand Thomas, a good lecturer in physics at the university’s Center for Explosion Studies, said that it was impossible to deal with gas explosions in the same way as fires because the whole event may only last a quarter of a second and normal water sprays do not have time to be effective．
Using the droplets of water to hold explosions resulted in the water being turned into a mist that allows some force of the explosion to be reduced．The mist slows down the combustion （燃烧） process and can stop a large amount of the gas igniting （点火,燃烧）, thus greatly reducing damage by limiting pressure development．With such a system, the operator has to decide at what point after a gas leak to activate the sprays．
The Center for Explosion Studies is the first of its kind in the UK and has been purposely-built for the study and implication of industrial explosions on land and sea．Research is developed to the causes of accidental explosions and they might be prevented．Full-sized imitative buildings can be built at the center where explosions and fires are created to test preventative equipment using sensors to monitor their efficiency．
Another area that the Welsh researchers have been looking at is how materials respond to explosions．The center also carries out research requested by individual customers．
Which of the following would be the best title for the passage?
A．Piper Alpha Oil Rig Explosion
B．Large Droplets of Water
C．A New Way of Controlling Gas Explosions
D．The center for Explosion Studies
The research finds that _____ in holding immediate explosion．
A．small water sprays are better than large droplets of water
B．small water sprays are not as good as large droplets of water
C．both small water sprays and large droplets of water are good
D．neither small water sprays nor large droplets of water is good
Dr Geraint Thomas implies that ______．
A．normal water sprays can put out fire effectively
B．gas explosions break out more quickly than fires
C．fires are easier to be held than explosions
D．gas explosions break out so quickly that there is no way to control it
Which of the following is not included in the research area of the Center for Explosion Studies?
A．To test the result of gas explosion．
B．To get some implications of industrial explosions on land and sea．
C．To find out how materials respond to explosions．
D．To find out when material respond to explosions．
“How to Train Your Dragon” by British author Cressida Cowell is one of the best pieces of children’s literature. A child can make a whole alternative universe with a vivid imagination and Toothless, the hero’s hunting dragon, thus turning a rainy day into an adventure of a lifetime. However, if you have never read the book but instead choose to see the film version, you might think you were seeing a new-age war movie meant for adults rather than children.
Let’s look at “Where the Wild Things Are” for further discussion. The story centers around a lonely eight-year-old boy named Max, who sails away to an island. Creatures living there declare Max their king.
What an amazing piece of children’s literature! A treasure for every child’s library. Yet, children were crying in the movie theatre. Owls were falling from the sky, chicken’s arms were being torn off, and a child was running around a dark abandoned world fighting evil as the only human. It was almost as if Hollywood could not imagine children enjoying a movie for its basic literature content. Hollywood might be right. But more and more its audiences are complaining that there is an increased amount of violence in children’s stories today than in the past.
While there appears to be a trend in our society to make more violence more accessible to younger children, books and literature are generally an exception. I truly believe that children’s literature has become more vivid, and more colorful. This is a great treasure for the children, and is certainly not violent. What has changed the children’s stories of today is not the writers, but the film industry. In some way, children’s literature is just being strangely twisted. I wonder how much influence the author have over this.
1.The Text is mainly about ________.
A. two good books for children
B. how a book is adapted into a film
C. whether children should go to movies
D. whether children’s literature is getting more violent
2.It can be inferred that the film “Where the Wild Things Are” is _______.
A. moving B. frightening C. interesting D. amazing
3.According to the text, the author thinks that ________.
A. the film industry’s treatment of children’s literature is wrong
B. writers should provide more colorful works for children
C. there is an increase in violence in children’s literature
D. children should read books rather than see films.
4.How does the text mainly develop?
A. By inferring. B. By giving explanations.
C. By providing examples. D. By making comparisons.
