A twofootlong spike sticks out of her side. Its a piece of fishing equipment that the
8、 shark ate carelessly. After travelling into her body, the spike punctured (刺) the sharks stomach.A man swimming in the water notices the shark. Then, he warns Sea World Marine Park in the nearby town of the Gold Coast. Sea World sends a 12person team from its rescue centre to where the shark has be

Soon, they find her lying on the seafloor. “Shell die without help, ” says Trevor Long, leader of the rescue centre.Using an onboard crane (吊车), the rescuers move the shark into their boats 13footlong tank (缸). Then Dr David Blyde gives the shark medicine an
10、d performs an operation to remove the spike. After that, the team sails with the shark to Sea World 33 miles away. They place the fish in a 49footlong tank and wait to see if she gets better.To give the sharks stomach some time to get better, she isnt fed for the first few days. A week after her ope
11、ration, Long offers the shark a small, dead fish. The animal refuses to eat. But days later when he drops another fish into her tank, the shark enjoys her meal. By now the sharks wounds have got better.Two weeks after her rescue, they take the shark back to the boat and return her to Moreton Bay Mar
12、ine Park. As the fish is lowered by the crane to the waters surface, two rescuers jump into the ocean and guide her into the sea.

16、ping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood.Then, months later, just before a competition, you can reinject (再注射) the old blood for a boost. As the redbloodcell count goe
17、s up, so does an athletes ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to burn off and the better you are able to perform.Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver me
18、dal. Best of all, “extra blood” was never something WADA tested for.But WADA wasnt going to sit by and be fooled. What it came up with in response might be a solution to stopping doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athle
19、te through testing done at regular intervals. The biological passports partial implementation (实施)recording blood and steroid levelsbegan in January 2014.When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect (检测) a drug. It
20、 will only have to detect resulting changes in the body. In the case of blood doping, if an athletes normal redbloodcell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.WADA is confident that the biological passport could even prevent genetic chan
21、gesthe ultimate, everlasting enhancementwhich are surely coming next. If an athlete inserts a performanceenhancing gene, it will probably leave detectable changes in the body, which would differ from the athletes features in the biological passport.5What does the underlined word “boost” in Paragraph

DRecovery.6What words can be used to describe the athlete biological passport?AComplex and expensive.BSimple and thorough.CFlexible and popular.DControversial and confusing.7What is the writers attitude towards the solution of antidoping mentioned in th

DUnconcerned.8What can we infer about the athlete biological passport?AIt can only be used to test blood doping.BIt has been completely adopted by WADA.CIt is the excellent alternative for many athletes.DIts a good choice to ensure fairness in sports.CAt 9：30

He added a function to the app that informed him whenever his screen time
27、was more than 40 minutes.“My phone would make a sound like a bee, and Id go and do something else. It was like something pushing me in the right direction，” he said. Holesh figured that if the system worked for him, it would work for others, and later that year he made Moment a free app. To date, it
