Summer is the season of mosquitoes. And mosquito bites are truly the worst-not only are they huge and painful, but they itch(发痒) like nothing else. And once you start scratching (挠), it’s hard to stop.

You can blame female mosquitoes for the trouble we all face. There is something that enters the skin while the mosquito is enjoying its blood meal. This is the protein that leads to the allergic reaction and itching. Basically, our immune systems see the protein as an enemy. This causes the local reaction we see as the bug bite. Our bodies are just particularly sensitive to mosquito bites. Other bug bites may not have the same effect on your immune system. Bees for example, are likely to produce more pain than an itch.

Scratching a mosquito bite is a double-edged sword. It feels so good, but it also makes the itch way worse. When you scratch, you may release more local histamine, the chemical in the skin that causes the itching, and you may also be spreading the allergen under the skin. If you tend to scratch until you bleed you’re putting yourself at risk for skin infections.

You’re not imagining it -mosquito bites do itch more at night. Most people itch more at night because we are less distracted as we try to fall asleep.

If you’ve ever wondered why some mosquito bites itch more than others, it totally depends on your body. Everyone responds differently to mosquito bites. While some people may have a minimal reaction, others may experience serious reaction. It just depends on your body’s immune system. People with so-called atopic traits, who are highly sensitive, are more likely to develop more serious local reactions after the mosquito bites.

1.What accounts for the itch you feel after a mosquito bite?

A.The blood type. B.The sensitivity of our skin.

C.The change of temperature. D.The protein from mosquitoes.

2.Why do mosquito bites itch more when scratch them?

A.Scratching them helps the blood to flow quicker.

B.Your skin will be infected after you scratch them.

C.Scratching them causes a special chemical to let out.

D.You focus more on mosquito bites when you are scratching them.

3.Why are some people bothered less by mosquito bites than others?

A.Their body’s immune system is less sensitive to the bites.

B.They pay less attention to the mosquito bites.

C.Their skin is thicker than others.

D.They get used to the bites.

4.What is the text mainly about?

A.The cure for mosquito bites. B.The itch caused by mosquito bites.

C.Why mosquito bites itch less than bee bites. D.How people respond to mosquito bites differently.

As ever, the Summer Movie Season is full of series and special effects. But if you’re prepared to look for them, you’ll find some smaller, odder films flying beneath the radar.

Book Club (May 18): A great quartet（四人组）of actresses (Diane Keaton, Jane Fonda, Candice Bergen, Mary Steenburgen) headline this comedy about a book club that gets back into a romantic mood after reading Fifty Shades Of Grey. It sounds ridiculous, but if that is a hook for a romantic comedy, it will be trying something new.

Tag (June 15): This comedy looks like it might share some DNA with The Hangover, as a group of friends reunite over the years to play a never-ending game of tag—Jeremy Renner, Jon Hamm, Hannibal Buress, Jake Johnson, Ed Helms, Leslie Bibb, Rashida Jones and Isla Fisher star. In other words: a lot of people we already know are funny, plus Jeremy Renner!

Uncle Drew (June 29): The attraction is that a young guy (Lil Rel Howery) has to renew a team of old men—played by NBA legends in old-age makeup—to play alongside his Uncle Drew (Kyrie Irving) in a big neighborhood game. This is such a strange idea for a comedy that I cannot wait to see it. Stars include Shaquille O’ Neal, Nate Robinson, Chris Webber, Lisa Leslie, Reggie Miller, J.B. Smoove and an up-and-coming comedy actress, Tifany Haddish.

Skyscraper (July 13): It wouldn’t be an action-movie season without Dwayne “The Rock” Johnson running off a crane（起重机）and leaping in a way that in reality would result in certain death but that in a movie results in a safe landing! I’m not here to tell you it’s more than it appears. I’m here to tell you it’s probably exactly as it appears. It comes out on July 13, so perhaps on the hottest day of the summer, forget your troubles and see The Rock save his family.

1.Which film can you enjoy this May?

A. Book Club.　　 B. Tag.　　 C. Uncle Drew.　　 D. Skyscraper.

2.What is strange about Uncle Drew?

A. A lot of people in old-age makeup are very funny.

B. A young man has to employ some NBA legends to play in a game.

C. Some current NBA superstars will star in the film.

D. The author cannot wait to see the film.

3.Which film is not a comedy?

A. Book Club.　　 B. Tag.　　 C. Uncle Drew.　　 D. Skyscraper.

Summer is the season of family travel. 1. Here are our top 5 things to teach your children before entering big crowds:

How Far They Can Go —　 2. For young children, you should establish a rule of always holding a parent’s hand. For older kids, you may be comfortable with a “I can always see you and you can always see me” rule.

To Call Your Real Name — Teach your children that you will find them, so it’s best if they stay in one place. Furthermore, teach them to call out your full name instead of “Mommy” or “Daddy” to help you more easily locate them.

How to Identify a “Safe Person” — Make sure your children know the best people to approach if they get separated from you. Employees working at the spot you’re visiting are generally always good, “safe people”. But what about places that may not have employees, like the beach? 3. Experts say that moms are often the most willing and best-equipped people to help kids.

What to Say — 4. Remember that if your children do get separated from you, they will likely be panicked, so don’t assume that they will know how to tell strangers that they are lost. Role-play getting lost and using simple sentences like, “I am lost” with your kids to help them know what to do if it actually happens.

Their Personal Information — Make sure your children know as much basic personal information as possible, including their full names, parents’ full names and telephone numbers and the address. 5.　　

A. Teach your children to look for a mom with kids.

Summer is the season to dive into new activities and relax. And right now is the time to make sure that you’re ready for the great outdoors, the holiday planning and travel, and the bathing suit beach days.

If you want to lose weight before summer, concentrate on dropping no more than a pound or two a week. 1.And when you trouble yourself, sooner or later you，re going to gain it back. Operate on a 500-calorie-a-day deficit (亏损). 2. So if you cut 500 calories a day for seven days straight, you’ll lose a pound a week right there.

Operating at a decrease of 500 calories a day should involve both eating less and moving more. For example, you could consume 300 fewer calories and bum 200 extra per day.

Include both healthy eating and exercise in your weight-loss plan, and break the 500-calorie goal into small groups to make it more reachable. 3.

To cut 100 calories: 4. Have vegetable pizza instead of pepperoni (意大利辣香肠). Use our Nutritional Needs Calculator to determine how many daily calories you should consume in order to lose, gain, or maintain your healthy goal weight. Once you’ve reached your goal, recalculate your nutritional needs for keeping extra weight off all summer long.

To burn 100 calories: spend 15 minutes biking. 5. Spend 20 minutes gardening. Keep on exercising at least 30 minutes daily a week. Reading food labels and counting calories or writing down what and when you eat can give you more control as well.

A. Here are some simple ways to get there.

B. Walk or run one mile.

C. A pound is 3,500 calories.

D. It is okay to have some snacks between your meals.

E. You should always make sure you get a lot of sleep.

F. Anything more than that usually means you’re troubling yourself.

G. Eat a chicken breast without the skin.

Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably, mosquitoes can do more than cause an itchy(发痒的)wound. Some mosquitoes spread several serious diseases, including Dengue, yellow fever and malaria.

Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.

Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains, use three senses to find a blood meal.

Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.

Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr Dickinson said, at first, the mosquitoes showed no interest in the objects at all.

“What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2, they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点).”

This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal, they also follow visual signals.

1.What do mosquitoes mainly use to find their targets?

A. Sense of smell. B. Sense of touch.

C. Sense of sight. D. Smart brains.

2.The first response of the mosquitoes to the objects in the experiment is 　　 .

A. to fly to the dark ones

B. to catch and stick to them

C. to take no notice of them

D. to attach themselves to them

3.How can we avoid being attacked by mosquitoes according to the text ?

A. Don’t let them see us.

B. Use dark objects to stop them.

C. Make them fly back and forth for hours.

D. Attract them to objects full of carbon dioxide gas.

4.What can be the best title for the text?

A. How Do Mosquitoes Survive?

B. Why Do Mosquitoes Need Blood?

C. How Do Mosquitoes Choose to Bite You?

D. Why Do Mosquitoes Attack the Human Being?

高二英语阅读理解简单题查看答案及解析

Mosquitos can infect you with Malaria, yellow fever, and dengue. All can kill you. So we spray large areas with pesticides (杀虫剂) .But this negatively affects the whole ecosystem and your health. Now there’s a new device, which claims to keep you and your loved one’s mosquito free.

The device was designed by two German engineers who were fed up with being bitten while camping. They found solutions containing ‘DEET’ — a damaging chemical which could be both harmful to us and the environment — worked best, but still only for 45 minutes maximum and that the traditional anti-pest devices didn’t work well! So, they designed the brand new type of bug killer, Moskinator.

Instead of trying to keep the mosquitos away, it actually attracts them, then catches and kills them! It lures (引诱) the flies and mosquitos near using a safe, completely harmless LED light. The flying pests (害虫) can’t resist the UV-PT light! Next to the LED light is a powerful, yet efficient reverse fan that sucks (吸) the insects through a one-way trapdoor. Once trapped in the drying basket they are dried to death by the fan a matter of 2 minutes. You can simply empty the dead bugs into the trash, without even touching them.

Does Moskinator really work in real life? We had some of our customers try it out in their homes. The results speak for themselves:

“My wife would complain she had a headache in the mornings whenever we used chemical pesticides. Now we use our Moskinator, and we wake up bite and headache free!”— Shane Maguire

“This Moskinator really works and you don’t have to worry about breathing any harmful chemicals.”— Jake Shearer

1.What is the name of the new device?

A.DEET. B.Moskinator  C.Malaria. D.UV-PT.

2.What is the function of the LED light?

A.It gives off natural light. B.It attracts flying pests.

C.It sucks pests inside. D.It dries pests to death.

3.Which of the following best describes the new device?

A.Innovative and effective. B.Traditional and cheap.

C.Power-saving and portable. D.Chemical free and soundless.

4.What is the purpose of writing the text?

A.To educate the readers. B.To entertain the readers.

C.To introduce a new device. D.To evaluate a new device.
