【3】
The more you can research before your trip, the easier it will be to keep a healthy lifestyle while travelling. To stay on track with your food, try to find a nearby grocery store or healthy food store, look up a couple of good restaurants that offer some healthy choices, and try to stay somewhere with a fridge or a kitchen.
Walk every day
Exploring where you want to travel on foot is an amazing way to take some exercise. Walk through nature to enjoy its beautiful scenery, listen to the sound of nature and take some wonderful pictures. 【4】
Rent a bike
Cover more ground while burning calories by renting a bike.

22、 English is full of funny expressions that don’t always make sense. What do they mean? How do we use them? And where did they come from? Idioms are phrases and sentences that do not mean exactly what they say. Even if you know the meaning of each word you see or hear, you may not understand the idiom because you don’t understand the culture behind it. Here are some English idioms based on animals.
When children jump around and act silly, for example, their parents may tell them to stop “monkeying around”. To “monkey around” means to do things that are not useful or serious, or to simply waste time.
But spending time playing with their family pets wouldn’t count as “monkeying around”. Many American families have a pet dog, which keeps the children company and makes them happy. Bu for some reason, which American language experts do not know, Americans use “dog” in a phrase that means to feel unwell. If you are “as sick as a dog”, you’re really, really sick and will have to stay home and rest or even go and see a doctor.
Apart from dogs, cats are also beloved in U.S. households. Sometimes you may hear them mentioned in Americans’ conversations, “I told you to keep that secret, but you have just ‘let the cat out of the bag’!” You probably guessed it — that idiom means to reveal a secret or tell facts that were previously unknown.
Dogs and cats don’t always get along, but they appear side by side in a commonly used idiom. When it rains heavily, people might say it’s “raining cats and dogs” outside.
Bad weather often ruins people’s plans for outdoor activities. But on a lovely day, they can go on an outing or have a picnic in the park. If a swarm of tiny bugs decide they love your picnic food and start to hover (盘旋) around you and your friends, then it would be really annoying, wouldn’t it? That experience perfectly explains why people often tell someone who keeps bothering them to “stop bugging me”.
Idioms are very common in both spoken and written English, so learning them is very important. If you need to understand English, or if you want to speak or write natural-sounding English, you have to learn idioms.
【1】According to Paragraph 1, idioms are_____.
A.phrases and sentences based on animals
B.expressions with rich cultural background
C.funny expressions that always make sense
D.the total sum of the meanings of the words
【2】“Monkeying around” can be used to describe children_____.
A.jumping around and wasting time
B.doing something useful and serious
C.playing with monkeys with their parents
D.spending time playing with their family pets
【3】What can be learned from the text?
A.Dogs and cats are friends by nature.
B.Bugs can be used to show your annoyance.
C.Americans believe cats can give away secrets.
D.Americans know the origin of the idiom “as sick as a dog”.
【4】How does the text mainly develop?
A.By sharing experiences. B.By making comparisons.
C.By providing examples. D.By quoting experts' words.
23、 [1] It happens countless times a day. A flower’s bright color and the smell of sweet nectar (花蜜) attract a bee. The bee stops by for a quick taste and small grains of pollen (the powder produced by a flower) stick to its body. The bee then travels to another flower of the same type and leaves the pollen as it has another meal. This is an example of animal pollination (授粉) — a process extremely important to plant reproduction.
[2] It’s not only plants that depend on animal pollination — humans do, too. Worldwide, nearly a thousand plants that we grow for food, spices, clothing fibers, and medicine depend on it. If pollination suddenly stopped, we would have no apples, tomatoes, coffee, and many other goods.
[3] This important process is carried out by more than 200,000 different animal species known as pollinators. Flies and beetles - the original pollinators - date back 130 million years to the first flowering plants. Birds, butterflies, and ants also do their part. Even nonflying mammals help out: monkeys tear open flowers with their hands, accidentally spreading pollen into the air and onto their fur.
[4] Pollinators are therefore important, but they are also at risk. Climate change, habitat loss, and invasive predators (入侵捕食者) all threaten them. The United States, for example, has lost over 50 percent of its honeybees over the past ten years. A serious threat facing bees is colony collapse disorder, when worker bees mysteriously disappear from their colony. Scientists are still trying to identify its cause.
[5] There is a quote attributed to Einstein that if bees ever disappeared, man would only have four years left to live. Whether that’s true or not does not really matter, says wildlife photographer Louie Schwartzberg: the key point is that there is a real danger. “The healthiest food we need to eat,” he says, “would disappear without pollinating plants. It’s pretty serious.”
【1】What might be left on flower B, as is shown in the picture?
A.Nectar.
B.Pollen.
C.Leaves.
D.Fur.
【2】What can be inferred from the text?
A.Pollination means a lot to fruits and grains.
B.Nearly a thousand plants depend on pollination.
C.Monkeys are the only nonflying mammal pollinators.
D.There are more than 20,000 different species of pollinators.
【3】What threat are honeybees faced with?
A.Climate change. B.Habitat loss.
C.Invasive predators. D.Colony collapse disorder.
【4】What does the underlined “a real danger” in the last paragraph refer to?
A.Bees are disappearing. B.Humans can only survive 4 years.
C.Food shortage is serious. D.No pollinating plants, no healthy food.
【5】Which might be the best title?
A.The Importance of Pollinators B.The Creator of Nature
C.The Wonder of Reproduction D.The Secret Life of Bees
24、It may come as a surprise that human beings are not alone in having invented vaccination. Work just published in the Journal of Experimental Biology by Gyan Harwood of the University of Illinois confirms that honeybees got there first.
Being social insects, honeybees are at a constant risk of diseases sweeping through their living places — the beehives. Most animals which live in crowded conditions have particularly strong immune systems, so it long puzzled insect experts that honeybees do not.
Part of the answer, discovered in 2015, is that queen bees vaccinate their eggs by passing into them, before they are laid, little bits of proteins from disease-causing virus. These will activate the development of a protective immune response in the developing young. But that observation raises the question of how the queen receives her antigen supply in the first place.
To find it out, Gyan Harwood teamed up with a group led by Heli Salmela. Together, they collected about 150 nurse bees and divided them among six queenless mini beehives equipped with groups of baby bees to look after. They fed the nurses on sugar-water, and for three of the beehives they mixed the sugar-water with P. larvae, a virus that causes a deadly disease.
In this case, to stop such an infection happening, Dr. Harwood and Dr. Salmela heat-treated and so killed the virus in advance. And, sure enough, it’s confirmed that some bits of P. larvae were getting into royal jelly produced by those bees which had been fed with the mixed sugar-water. Moreover, examination of this royal jelly revealed increased levels, compared with royal jelly from bees that had not been fed with P. larvae, of defensin-1, which is thought to help bee immune systems defend the bees from virus infections.
These findings suggest that nurse bees are indeed, via their royal jelly, passing antigens on to the queen for vaccination into her eggs. They also mean, because baby bees, too, receive royal jelly for the first few days after they hatch, that the nurses are vaccinating as well. It seems protective.
【1】What has long puzzled insect experts concerning honeybees?

【2】When does the queen transfer the antigen to the young bees?
A．After they hatch.
B．Before the eggs are laid.
C．When they are growing up.
D．Before her immune system is activated.
【3】What is the most important in protecting the young bees from virus infection？
A．The sugar-water.
B．Royal jelly free from antigens.
C．Increased defensin-1.
D．Care from the professors.
【4】Which of the following can be the best title for the text?
A．Sweeping Diseases Threaten Honeybees
B．Baby Bees Are Vaccinated by the Nurse Bees
C．Vaccination Strengthens Honeybees
