When Renae was 14, her father got a new job and the house needed to be free of noise. “Chloe liked barking,” Renae says. “I didn’t want to lose my dog but I didn’t have any _________ as a kid.” With no easier _________, the family sent Chloe to a humane society(动物保护协会).

2 . Sounds from human activity flood across the oceans, causing trouble to ocean creatures. And climate (气候) change may make some places even louder.

Researchers have expected the oceans to get noisier because of increasing human activity. “The more goods you buy, the more shipping you have, so the more noise you have.” says Luca Possenti, a scientist studying sound in the ocean at the Royal Netherlands Institute. But Possenti and his co-worker realized that climate change might also influence how sound travels through the water.

Human-caused climate change is changing ocean temperatures, salt levels and acidity (酸度). So Possenti’s team used computers to model how those factors (因素) influence noise levels across the world’s oceans.

When waters become more acidic, they can’t take in sound at some wavelengths as well, so those sounds can travel further, adding to the noise in some areas. This effect is relatively small. Other changes impact the sound level more, the researchers found. Changes to temperature and salt levels can change how well different layers (层) of the ocean mix, which, in turn, impacts how sound travels.

The team predicted (预测) models of the world in about 70 years if climate change continues. And then they compared them with models of the world now. In the North Atlantic, they saw an increase in sound levels in the upper 125 meters of the ocean. This was caused mostly by ice melting (融化) off of Greenland, forming a cold layer of water near the ocean’s surface. Sound traveling through water tends to go toward the coldest area. As a result, sound waves tended to get stuck in the cold top layer-spreading further out across the water, instead of traveling deeper. That increased the noisiness at this depth in the North Atlantic. The models suggested that a single ship could sound about five times as loud underwater because of this. Considering all the ship traffic between Europe and North America, that may stress animals, many of which communicate, and catch food with sound.

6 . Keeping plants at home is a healthy and comfortable way of life. The following houseplants can create a most beautiful piece of green for your home.

Bird’s Nest Fern (蕨)

The bird’s nest fern is a good choice for anyone with a house that wouldn’t support sun-loving species. It’s a hardy fern variety adapting to living on forest floors, where the air tends to be cool and damp. It likes to be misted as well, but this doesn’t always mean you need a misting bottle—spraying (喷洒) it in the sink or hanging it near a shower often works as well.

Chinese Money Plant

This is a flowering species that might be most appropriate for experienced plant gardeners looking for a new challenge. It prefers a moderate amount of indirect light, and tends to dry out slightly between watering sessions. It produces new plants easily without any input, directly from its root system. These can coexist in the same pot for a time.

Resurrection Plant

This native of the Mexican desert has adapted to surviving in extreme drought by curling (蜷缩) into a ball and remaining in seemingly lifeless state for years, if necessary. In this form, it can be transported by the wind across the dry landscape to areas with water. It will revive within hours in a shallow bowl of water, unfolding and transforming into a fresh and green moss (苔藓).

Snake Plant

This is a striking houseplant that can be an especially good option for new plant owners who you might not trust to keep a plant alive. It grows happily in almost any condition. While it prefers bright light, it doesn’t mind shade or even artificial light. Plus, thanks to its thick, fleshy leaves, it stores water with remarkable efficiency, which makes it survive without water in the earth.

1. What is special about the bird’s nest fern?

A．It prefers shade.	B．It is sun-loving.
C．It tends to grow in the sink.	D．It can return to life after death.

2. Which plant will test its owner’s gardening skill most?

A．Bird’s nest fern.	B．Chinese money plant.
C．Resurrection plant.	D．Snake plant.

3. What do resurrection plant and snake plant have in common?

A．They demand attentive owners.	B．They are very drought-tolerant.
C．They will curl for self-protection.	D．They can store water for drought.

7 . New research shows that removing black rhinos’ horns (犀牛角) to make them less attractive to illegal hunters is reducing their territory (领地) sizes and making them less sociable with each other.

The study, published in the journal PNAS, found that de­horned South African rhinos have home ranges that are 45 per cent smaller than those of complete animals, and that they were 37 percent less likely to engage in social interactions.

“The big, dominant bulls that used to have very large territories that overlapped with a lot of females may now have much less territory and much less reproductive (繁殖的) success,” says Vanessa Duthé, who led the work at Switzerland’s University of Neuchâtel.

“It’s really hard to predict the effects of this,” she says. “It doesn’t mean that population success will necessarily decline, because it might open up gaps for younger males that would not have had the space or the means before.” Indeed, a University of Bristol study published last year showed that de­horning (去角) does not negatively affect populations overall.

But such unintended behavioral consequences necessarily feed into judgments about whether this highly invasive procedure is worthwhile. Remarkably, perhaps, there is little hard evidence either way. “No one’s put all the data together to say whether it’s a really effective measure,” says Duthé.

“What is clear is that the introduction of de­horning and a decline in illegal hunting has occurred at the same time,” she adds. “But de­horning has been accompanied by other conservation measures that may be more effective.”

“It’s incredibly complicated,” says Lucy Chimes, a member of the Bristol team. “There are so many other factors involved. You have to consider what other security measures are being carried out — fencing, patrols, staff numbers — and poverty levels surrounding parks, their nearness to national borders and whether there is community engagement.” Chimes is currently planning a project that aims to separate these and other factors. In the meantime, Duthé believes that de­horning is a worthwhile tool of last course of action. “A rhino that is behaving a little bit strangely is better than a dead rhino.”

1. What is the purpose of removing the horns of black rhinos?

A．To make them less sociable.	B．To protect them from being hunted.
C．To reduce their home ranges.	D．To affect their reproductive success.

2. What does the underlined phrase “invasive procedure” in paragraph 5 refer to?

B．Various factors lead to the decline in illegal hunting.

C．De­horning is the last action researchers will take.

D．Rhinos are supposed to behave a little bit strangely.
