Dogs and cats are not for students who live in the dormitory. Just think about the noise, the smell and all that wild behaviorchewing on whatever they can get their teeth on, or knocking over the trash can. But don't feel sad. There are smaller and less destructive pets to make your dormitory life colorful.

Betta fish
They make great pets with their big personality and astonishing colors, ranging from bright red, dark blue to lemon yellow. Unlike many fish, most bettas react to their owner's presence and become more active when they are nearby, which is unusual in the fish world.

Chinchillas
Without bad smell, about the size of a rabbit and with fur so dense that they can't get pests such as fleas(跳蚤), the friendly creature originally from the Andes Mountains in South America makes an ideal indoor pet. Chinchillas are very social animals, so if you only have one, you will become its family. In cold winter days, in a glace at this fury pet in a dorm will bring you a lot of warmth.
Land hermit crabs

In a society where owners are often asked “Are they tasty？”， land hermit crabs are among the most unlucky animals commonly kept as pets. But they are easy to care for, inexpensive and fascinating to watch. And the fact that they don't cause any allergic reactions makes them perfect for college dormitories.

Redeared sliders
If you're interested in a lifelong friend, a redeared slider makes a wonderful pet. If well cared for, they can live for around 40 years. But there are a couple of things you should know. Redeared can grow to an adult size of up to 30cm! So you may need a larger tank quickly. In addition, you will need to provide UV lighting, water heater, and a swimming area and a basking (晒太阳) area.

Travel Unaccompanied
Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.
Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.
In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen. It is challenging. This is what drives young people to travel alone.It is seen as character building and a chance to prove that they can make it on their own.
Chris Richardson decided to leave his sales job in Australia to go traveling last year.He set up a website, The Aussie Nomad, to document his adventures. He said he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person，” said the 30yearold.
Richardson describes traveling alone like “a shot in the arm”， which “makes you a more confident person that was ready to deal with anything”. He said: “The feeling of having conquered something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”
The great 19th century explorer John Muir once said: “Only by going alone in silence can one truly get into the heart of the wilderness.”

Three Central Texas men were honored with the Texas Department of Public Safety’s Director’s Award in a Tuesday morning ceremony for their heroism in saving the victims of a serious twocar accident.
The accident occurred on March 25 when a vehicle lost control while traveling on rainsoaked State Highway 6 near Baylor Camp Road. It ran into an oncoming vehicle, leaving the occupants trapped inside as both vehicles burst into flames.
Bonge was the first on the scene and heard children screaming. He broke through a back window and pulled Mallory Smith, 10, and her sister, Megan Smith,9, from the wreckage.
The girls’ mother, Beckie Smith, was not with them at the time of the wreck, as they were traveling with their baby sitter, Lisa Bowbin.
Beckie Smith still remembers the sickening feeling she had upon receiving the call informing her of the wreck and the despair as she drove to the scene.
Bozeman and Clemmons arrived shortly after Bonge and helped rescue the other victims and attempted to put out the fires.
“I was nervous,” Bozeman said. “I don’t feel like I’m a hero. I was just doing what anyone should do in that situation. I hope someone would do the same for me.”
Everyone at the accident made it out alive, with the victims suffering from nonlifethreatening injuries. Mallory Smith broke both femurs(股骨), and Megan had neck and back injuries. Bowbin is still recovering from a broken pelvis(骨盆), ankle and foot.
The rescuers also were taken to the hospital and treated for cuts and smoke breathing, Bonge said.
In addition, Bozeman got to meet accident victim Anthony Russo in the hospital after the accident, where Russo presented him with a glass frame inscribed with “Thank you”, Bozeman said. Those involved in that fateful encounter on Highway 6 credited God blessing for bringing them together.
“Whatever the circumstances, Tuesday’s ceremony provided a time to be grateful for those who put their lives on the line for the lives of complete strangers,” Beckie Smith said, “We’re calling it The Miracle on Highway 6.”
What’s the main idea of the passage?

A．Three persons were awarded for rescuing victims in a car accident.

B．Three ordinary people were regarded as great heroes.

C．Several victims were carried to safety from the burning cars.

D．A car accident occurred on rainsoaked State Highway 6.

New findings from Queen’s University biologists show that in the plant world, bigger isn’t necessarily better.
“Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant,” says Queen’s Biology professor Lonnie Aarssen. “But our research shows it’s virtually the other way around.”
Previous studies showed that larger plant species monopolize(垄断) sunlight, water and other resources, limiting the number of smaller plant species that can exist around them. But the research has proved that this is not generally the case in natural vegetation.
In the Queen’s project, PhD student Laura Keating targeted the largest “host plants” of 16 woody plant species growing in the Okanogan Valley, British Columbia. The research team calculated the number and variety of plants that neighbored each large host plant. They then randomly selected plots without host plants and calculated the plant species there as well. The research showed that the massive trees have no effect on the number of species with which they coexist.
Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen notes. Larger species generate physical space niches under their shelters where smaller species grow well. Smaller plants are much more effective than large trees at using available resources. They also produce seeds at a much younger age and higher rate than their bigger counterparts, and settle down much more quickly—thuscompeting with the newly-born plants of larger species.

A．Smaller plants may have many advantages over their neighbors.

B．In the plant world, the bigger is better than the smaller one.

C．To be a good competitor in the forest, you have to be a small plant.

B．Smaller plants can limit the number of plant species around them.

C．Smaller plants produce seeds at a higher rate than their bigger counterparts.

D．Larger trees are more effective than small plants at using available resources.

Which is the CORRECT order in the Queen’s project?
