Bees play a vital role in the world. Unfortunately, bees are dying by the second.
The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption, it is essential to the insects. Honeybees store honey in their hives (蜂巢) in order for the bees to have energy for their flight muscles and for heating the hive during the winter period. They collect pollen (花粉) which supplies protein for young bees to grow.
According to Honey, com, the increased production and quality of agricultural crops as a result of honey bee pollination is valued &t more than1 $14/ 6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.
So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides (农药). Honeybees who are exposed to pesticides result in the damage to their neurological (神经的) functions, specifically memory or behavior. And that's why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes to the decline of bees, including the destruction of natural habitat, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population.
Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting bee-friendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.
1.Why do honeybees store honey in their hives?
A. To provide enough honey for human to consume.
B. To draw protein out of honey for young bees.
C. To help attract other insects and make hives stronger.
D. To strengthen bee muscles and heat hives in winter.
2.Apples and beans are mentioned in the third paragraph to show that _.
A. bees supply human beings with basic food
B. bees mainly live on these agricultural crops
C. bees are of great importance to fruits and vegetables
D. bees can bring in more money for famers every year
3.What is most likely to cause the worker bees to leave their hives behind?
A. The lack of food.
B. The abuse of pesticides.
C. The fighting among bees.
D. The destruction of the habitats.
4.What would the author probably discuss in the paragraph that follows?

Despite the vital role they play in many ecosystems, animals considered to be “ugly” are being ignored by scientists. A study had found uglier animals attract less attention and less funding when it comes to conservation efforts and research. This could mean the ugliest animal population could be under threat.
The study was conducted by wildlife biologists Trish Fleming and Bill Bateman in Perth, Australia. They looked at research publications concerning 331 Australian mammal species that broadly fell into categories they labeled as “the good, the bad and the ugly”. It turned out that studies into “the good group” and “the bad group” were carried out while the “ugly group” was ignored.
Ugly animals, such as the fruit bat and the tree bat, are being ignored by conservationists. And some animals are even becoming endangered because of how they look. The Madagascan lemur(狐猴)called the aye---aye is so ugly that the natives have long seen them as a bad sign, or a sign of death, so they kill them whenever they see them. Other ugly animals under threat include the dugong(儒艮)and the proboscis monkey(长鼻猴).
Despite making up 45% of the 331 species studied, the ugly animals have attracted little attention from scientists. “We know so little about the biology of many of these species,” said Trish Fleming. “For many, we have catalogued their existence, but when it comes to understanding what they eat, their habitat needs, or how we could improve their chance of how we could improve their chance of survival, we are still in the dark.”
With Bill Bateman, Trish Fleming has called for improved funding for the lesser known mammals. “It would be ‘tragic’ if humans ended up causing the extinction of more species without even knowing anything about them,” they said.
1.Based on the text, the “ugly” animals _________
A. are increasing in number
B. get more conservation funds
C. play an important role in the ecosystem
D. cost quite a great deal of money in research
2.Which of the following is true according to the text?
A. People see the dugong as a sign of death
B. More attention has been paid to “the ugly animals”
C. There was not enough study about “the ugly animals”
D. Trish and Bill did research on 331 Australian mammals
3.The main reason for some animals’ being endangered may lie in _________.
A. their unpleasant looks B. their broad categories
C. their economic values D. their lovely appearances
4.The best title for the text would be _________.
A. The Ugliest Animal in the World
B. The Ugly Species Are under Threat
C. The Living Habits of the Ugly Species
D. The Proboscis Monkey Is Endangered

Bees and butterflies are active during the daytime. They get a lot of attention for their roles as pollinators(传粉者).But moths(蛾)aren't given the prominence they deserve.
Actually, moths are seen much less often, because they're active at night. Moth bodies often seem furry. Pollen—a yellow powder in the center of most flowers, from one flower sticks to their bodies and falls off when they move to other flowers. Scientists studied insects around nine ponds on farmlands in the United Kingdom. They visited these ponds once a month from March to October.
They studied three groups of insects: moths, bees that normally work together, like honey bees, and flying insects which work alone, such as butterflies. At the ponds, the scientists caught these flying insects and died to collect pollen from their bodies. In all, the scientists checked 838 moths, 632 other insects which work alone, and 1,548 honey bees.
By studying the pollen they collected, the scientists were able to see which plants the insects had visited. The moths had pollen from 47 different kinds of plants, including seven plants that bees don't normally visit. The honey bees had pollen from 46 different kinds of plants. The other insects that work alone had visited 45 different kinds of plants. Richard Walton, who led the study, says that bees usually choose the plants with the most nectar(花蜜)and most pollen. However, moths pollinate many different plants, filling in the gaps left by the daytime pollinators.
Not only do moths pollinate plants, they also provide important food for birds and bats.
But, like many other insects, moth numbers have dropped greatly in the last 50 years, mainly because of pesticides and the loss of natural lands. Just like bees and butterflies, moths are worth protecting. "Moths are by no means less important," says Dr. Walton.
1.What does the underlined word probably mean in paragraphl?
A.Praise. B.Chances.
C.Concerns. D.Future.
2.What is the second paragraph mainly about?
A.Moths and other insects' living habits.
B.Research on insects' spreading pollen.
C.Classification of insects by scientists.
D.The ways in which moths carry pollen.
3.Compared with bees, which best describes moths?
A.They are less choosy. B.They eat less in the daytime.
C.They are more diverse. D.They carry more pollen.
4.What is the best title for the text?
A.Moths Pollinate Plants Strangely
B.Moths Are More Vital Than We Think
C.Moths Help Bees to Pollinate Plants
D.Moths Visit Some Flowers Bees Skip

Most people have heard the sound of bees among flowers. Bees live almost everywhere in the world except in the Arctic areas.
Many kinds of agriculture depend on these small, social insects. Without bees, fruit and nut growers as well as many other farmers would not have a crop.
There are more than 20,000 kinds of bees. But only honey bees make enough honey for people to use. Honeybees are highly-organized social insects. They work together in a group, called a colony（群体）. Each colony lives in a hive（蜂房）. It contains one queen bee -- she lays all the eggs from which the members of the colony come. Each colony has only a few hundred males, called drones. The majority of all bees in a colony are workers, which are all females.
Bees even have a special stomach, called a honey stomach, which is used to store sweet fluid that the bees gather from flowers. Bees also have long hairs on their body and legs. These hairs capture pollen（花粉） as bees go from flower to flower. Some of the pollen is taken back to the hive. Some, however, is passed to the next flower. This is how many plants are fertilized. Pollen is the reproductive material of plants. Many important agricultural crops depend on bees for fertilization.
Inside their hives, bees store sweet liquid from flowers and pollen as well. They may even gather sweet liquid from some other kinds of insects. These kinds of sweet liquid are also stored in the hive.
Bees make honey through a process. They add liquid from their own mouths to sweet liquid into simple sugar. As the honey is stored, it dries. It becomes thicker and darker.
Although bees are often thought of as honey makers, they provide a surprising number of products. Also, their greatest economic value is in fertilizing crops-not in making honey.
1.The passage is mainly about________.
A．bees and their colony
B．the way for bees to pass pollen
C．bees and agriculture
D．the process for bees to make honey
2.Honeybees are social insects because________.
A．they work in groups B．there is queen bee in every colony
C．they live in a hive D．each of them does the same job
3.The most valuable thing honeybees do for people is in ________.
A．making honey B．fertilizing crops
C．making flowers grow better D．producing pollen
4.The word “fertilize” in the sentence “This is how many plants are fertilized” probably means “________”.
A．to make plants strong and productive
B．to make soil rich for plants
C．to start the development of young flowers
D．to introduce pollen into plants

Birth order plays a vital role in deciding the characteristics of a child. And when it comes to the middle child, it certainly plays a huge role. The middle children go through some things only they can understand. 1.
Mostly, middle children have to share a room. 2. They need to share a room with an elder one because they're too young to sleep alone. And just when they think they'll finally have a room of their own, a voice is heard saying, “Dear, please share the room with your younger one, as he's too small to sleep alone.”
Middle children tend to share clothes with their siblings (兄弟姐妹). Their cupboard is full of handmedowns from their older sibling, and they need to wear his clothes. 3. They can always show off their elder sibling's clothes and things at school. Also, they get to pass their own clothes to their younger sibling.
4. They're liked by both, because they can relate well to both generations. On one hand they can recall how much fun it was watching Garfield and Friends, and on the other hand they can talk about the latest video game released in the market.
Siblings' talking is one interesting thing about a middle child. They are not as boring as they appear.5. Also, thanks to the divided attention at home, middle children are independent and need not rely on anyone.
A．Instead, they are very artistic and creative.
B．But this comes with its own advantage too.
C．Here are some things a middle child can relate to.
D．They rarely enjoy the experience of having their own room.
E．And the dream of having their own room is completely destroyed.
F．They're the problem solvers between their older and younger siblings.
G．As a middle kid, they are the bridge between their younger and older siblings.

Technology is playing a vital role in preservation and ecology research. Drones (无人机) hold huge _______ in the fight to save the world’s remaining wildlife from extinction. So researchers can now track wild animals through dense forests and monitor whales in vast oceans. It’s estimated that up to five living species become extinct every day, making it urgent that universities develop new technologies to capture the data that can persuade _______ to act.
The British International Education Association hosted a conference in January to _______ the importance of technological solutions in protecting vulnerable (易受伤害的) species and ecosystems. Speakers underlined how technology can help _______: drones can circle high above the ocean to spot whales, while certain cameras can identify members of an individual species.
According to Claudio Sillero, biology professor at Oxford University, technology is changing how preservation research is done — but it’s in a(n) _______ way. As technology gets better and cheaper, researchers become better at doing what they were already doing. _______, remote sensing used to be a very technical tool but is now widespread, and everyone uses global positioning system (GPS) for surveying.
But teaching preservation and ecology courses in university _______. Some teach drone surveying methods in depth while others don’t even mention them. “The fact is, using drones is quite a(n) _______ to the interdisciplinary (跨学科的) ‘unknown’ of engineering, and potentially an area where lecturers may not feel confident to teach yet,” Serge Wich, an expert in primate biology says. “Students are taught about _______ technologies such as automatic sound recorders, but drones are often missing from university teaching. Consequently, drone use among researchers is still fairly ________ and focused on getting photos.”
Wich’s team of researchers used techniques to develop a fully automated drone technology system that ________ and monitors the health of endangered animals globally. It’s designed to be cheap, stable and simple to use, so that local communities in developing countries can operate it ________ without technical background. Yet it’s not more widely used on the grounds of researchers’ lack of skills to use this technology. In biology, where drones are used, few can program an algorithm (算法) specifically for their preservation or research problem. “There’s much that needs to be done to ________ those two worlds and to make AI more user-friendly so that people who can’t program can still use the technology,” Wich says.
________, the sad truth is that better technology alone will not save any more species from dying out, Greengrass warns. “As human populations increase, so do threats and pressure on wild places. Preservationists are ________ for not doing enough but it’s often an issue of people, conflict and governance.” Technology may help provide far greater knowledge, but governments still need to act.
