6.In 1985,a lionfish was caught off the coast of Florida.Now they can be found not only in the Atlantic Ocean but also in the Gulf of Mexico and the Caribbean Sea.And they are continuing to move south.Lionfish are native to the Indian and western Pacific Oceans.So how did they end up in the Atlantic?Scientists believe some pet owners abandoned their unwanted lionfish and poured them into the sea.Little did they know the trouble their actions would cause.
       The Atlantic Ocean turned out to be a comfortable home for lionfish.Their venomous spines (毒刺) prot ect them from sharks and other fish.Female lionfish can spawn (產(chǎn)卵) every few days,producing as many as 2 million eggs per year.Other big fish would have competed with lionfish for food.But overfishing has removed many of these large fish.As a result,the fish have eaten so much that they have grown to be more than three times the size of their cousins in the Pacific and Indian Oceans."They eat mostly fish,"says Stephanie Green,a scientist at Oregon State University.
       All that eating has caused great changes.Scientists have found that when lionfish are present somewhere,many other fish,which are small enough for them to eat,disappear.Some of the fish they eat are greatly missed in their habitats.For example,parrotfish eat certain plants off corals (珊瑚),which allows corals to grow better.But they are now disappearing due to lionfish.
       Scientists say lionfish are here to stay.But there are ways to deal with the problem.The key,says Green,is to keep lionfish numbers in check.In Florida,divers can now go through a special training program and get certified (授予合格證書) to catch lionfish in areas where fishing is not usually allowed.And a number of restaurants have added the fish to the menu."It's going to be a long-term battle,but the missing sea species will come back someday,"says Green.
25.What can we learn about lionfish?D
A.Most of them have gathered in the Atlantic.
B.All of them are almost the same size.
C.They eat other big fish and even sharks.
D.Its population is growing very quickly.
26.Parrotfish were mentioned to show lionfish'sB.
A.loneliness                       
B.harmfulness
C.weakness                        
D.carelessness
27.What is Stephanie Green's attitude towards the battle against lionfish?C
A.She doubts it.
B.She is worried about it.
C.She is hopeful of it.
D.She thinks it is against the law.

5.The public were shocked in March when the news that improperly stored vaccines (疫苗) worth millions of dollars were sold to patients all over the country.
China is trying to rebuild public confidence in vaccines after the news struck fear into the hearts of parents.
Chief government officials should be dismissed if serious vaccine violations (違規(guī)) took place in their jurisdictions (管轄區(qū)),according to a revised regulation (規(guī)定) approved by the State Council.The regulation was passed on Saturday and took effect immediately,the report said.It strengthens management rules for vaccines,including their transportation and storage,and increases punishments for violators.
The regulation requires B-class (non-compulsory) vaccines to be given out like A-class.It also requires disease control departments,hospitals and clinics to keep records of purchases and received inventory (存貨清單).China will establish a system to track vaccines,according to the regulation.Companies and user agencies must record use,so all vaccines can be tracked across their life cycle.
China will also raise the amount of compensation paid to those suffering abnormalities (反常) after receiving vaccines.Measures under consideration include the introduction of commercial insurance to improve fairness and efficiency in compensation.Commercial insurance is expected to play an important role in compensating people for any health problems connected with vaccines.In the past,responsibility for compensation belonged to vaccine producers or to the government.
Meanwhile,local authorities are trying to reduce public worries.At Zhcheng hospital,health workers were spreading vaccine information to parents on Monday.In Northeast China's Jilin province,authorities are pioneering a digital system that makes vaccines storage transparent to the public.In Hefei,capital of Eastern Anhui province,authorities have developed a smart phone application that shares vaccine information.
Immunization (免疫) is the most economic,effective and safest way of preventing,controlling and getting rid of communicable diseases,said Mao Qun'an,spokesperson for the National Health and Family Planning Commission.Although vaccines can provide immunization against certain diseases,they can also cause side effects and result in serious physical harm in some individuals because of a person's health condition,although the chances of developing problems are extremely low,according to experts.
Vaccines stand for the primary means in most countries to prevent and control infectious diseases,and parents should get their children vaccinated as required by the government,said Yu Wenzhou,an expert at the Chinese Center for Disease Control and Prevention.
