A: Not everything about Halloween has to be dark and scary, it can also be green and eco-friendly. Here with some great ideas is Danny Seo, living-green contributor for Better Homes and Gardens. Hello, Danny ! Happy Halloween to you !
B: Same to you.
A: Let’s start with your solar power ghosts.
B: Yeah, can we all have solar lights And they are as super energy-efficient because they use the power less on the charge-up. So why not just take an old bed sheet Look what I’m gonna do. You hang it over the solar light, you take a little sharpie, draw on the face of ghost, look, you’ve got an illuminated ghost. So at night, when the sun goes down and solar lights turn on you’ve got these glowing ghosts hanging in the trees.
A: Look at that. Isn’t it beautiful That’s how it looks like, that’s pretty awesome.
B: And kind of spooky and it uses the power of super energy-efficient lights in a very creative way.
A. how to have a happy and interesting Halloween
B. how to deal with treats and candies after Halloween
C. how to be environment-friendly on Halloween
D. how to get along with kids on Halloween

Virtually everything astronomers know about objects outside the solar system is based on the detection of photons-quanta of electromagnetic radiation. Yet there is another form of radiation that permeates the universe: neutrinos. With (as its name implies) no electric charge, and negligible mass, the neutrino interacts with other particles so rarely that a neutrino can cross the entire universe, even traversing substantial aggregations of matter, without being absorbed or even deflected. Neutrinos can thus escape from regions of space where light and other kinds of electromagnetic radiation are blocked by matter. Not a single, validated observation of an extraterrestrial neutrino has so far been produced despite the construction of a string of elaborate observatories, mounted on the earth from Southern India to Utah to South Africa. However, the detection of extraterrestrial neutrinos are of great significance in the study of astronomy. Neutrinos carry with Their information abou
A. get through,
B. pass by.
C. interact with.
D. derive from.

Neutrinos can thus escape from regions of space where light and other kinds of electromagnetic radiation are blocked by matter. Furthermore, neutrinos carry with them information about the site and circumstances of their production: therefore, the detection of cosmic neutrinos could provide new information about a wide variety of cosmic phenomena and about the history of the universe.
But how can scientists detect a particle that interacts so infrequently with other matter Twenty-five years
A. have been detected for 25 years.
B. possess a variable electric charge.
C. are usually extremely massive.
D. record information about their own origin.
