¡¡¡¡4. According to the passage£¬ one advantage that neutrinos have for studies in astronomy is that they
¡¡¡¡£¨A£© have been detected for the last twenty-five years
¡¡¡¡£¨B£© possess a variable electric charge
¡¡¡¡£¨C£© are usually extremely massive
¡¡¡¡£¨D£© carry information about their history with them
¡¡¡¡£¨E£© are very similar to other electromagnetic particles
¡¡¡¡5. According to the passage£¬ the primary use of the apparatus mentioned in lines 24-32 would be to
¡¡¡¡£¨A£© increase the mass of a neutrino
¡¡¡¡£¨B£© interpret the information neutrinos carry with them
¡¡¡¡£¨C£© study the internal structure of a neutrino
¡¡¡¡£¨D£© see neutrinos in distant regions of space
¡¡¡¡£¨E£© detect the presence of cosmic neutrinos
¡¡¡¡6. The passage states that interactions between neutrinos and other matter are
¡¡¡¡£¨A£© rare
¡¡¡¡£¨B£© artificial
¡¡¡¡£¨C£© undetectable
¡¡¡¡£¨D£© unpredictable
¡¡¡¡£¨E£© hazardous
¡¡¡¡7. The passage mentions which of the following as a reason that neutrinos are hard to detect£¿
¡¡¡¡£¨A£© Their pervasiveness in the universe
¡¡¡¡£¨B£© Their ability to escape from different regions of space
¡¡¡¡£¨C£© Their inability to penetrate dense matter
¡¡¡¡£¨D£© The similarity of their structure to that of nucleons
¡¡¡¡£¨E£© The infrequency of their interaction with other matter
¡¡¡¡8. According to the passage£¬ the interaction of a neutrino with other matter can produce
¡¡¡¡£¨A£© particles that are neutral and massive
¡¡¡¡£¨B£© a form of radiation that permeates the universe
¡¡¡¡£¨C£© inaccurate information about the site and circumstances of the neutrino's production
¡¡¡¡£¨D£© charged particles and light
¡¡¡¡£¨E£© a situation in which light and other forms of electromagnetic radiation are blocked
¡¡¡¡9. According to the passage£¬ one of the methods used to establish the properties of neutrinos was
¡¡¡¡£¨A£© detection of photons
¡¡¡¡£¨B£© observation of the interaction of neutrinos with gamma rays
¡¡¡¡£¨C£© observation of neutrinos that were artificially created
¡¡¡¡£¨D£© measurement of neutrinos that interacted with particles of seawater
¡¡¡¡£¨E£© experiments with electromagnetic radiation
