【題目】 In 1848 gold was found in California. Thousands of people rushed there to get some. Many people liked living there. But there wasn’t a whole lot between California (CA) and Missouri (MO), where the nearest trains ran. The train line to California wasn’t finished until 1869.

In I860 and 1861, the Pony Express was the fastest way to get news to and from the West. The trail that they rode was around 2000 miles long. It took most people weeks or months to ride that far. The Pony Express could make the trip in just ten days. Those speeds were unheard of at the time. So how did they do it? Well, they had a good system.

The Pony Express had 184 stations along the trail. The stations were around ten miles apart. This is about how far a horse could run at a gallop (疾馳) before tiring. The rider would switch to a new horse at each station. He would only take his mail pouch (郵袋) with him. Every 75-100 miles, the rider would get to a home station. At each home station, riders would rest. The mail never stopped moving, even while the horses and riders rested.

It was tough to ride for the Pony Express. Each rider had to weigh less than 125 pounds. Speed was the key. Most of the riders were teenage boys. They rode at a fast pace for up to 100 miles a day. If there were an emergency, one might have to ride 200 miles in a day.

The Pony Express filled an important role for a time, but it did not last. The Civil War started in April of 1861. On October 24th, 1861, the first telegraph line to California was finished. This linked them to the rest of the country. People could send messages in an instant. Two days later the Pony Express closed.

【1】Which happened first?

A.The Pony Express was started.B.The American Civil War broke out.

C.The train line to California was finished.D.Settlers rushed to California to find gold.

【2】How long did it take the Pony Express to send mail from CA to MO?

A.About 24 hours.B.About ten days.

C.About twenty days.D.About one month.

【3】What would a rider do at the home station?

A.Give his mail to a new rider.B.Rest a while and go on riding.

C.Collect new mail for customers.D.Feed the horse and check the mail.

【4】What is the author’s purpose in writing the text?

A.To prove communication industry develops rapidly.

B.To explain why horses were used to deliver mail.

C.To describe the I860 - 1861E Fastest Mail Service.

D.To tell the brave stories of the Pony Express.

【題目】 A few weeks ago, scientists at Ukraine's Vernadsky Research Base in Antarctica found their usually white surrounds were covered in a shocking blood-red. For such a mess, the culprits behind this horrible scene are tiny.

“Our scientists have identified them under a microscope as Chlamydomonasnivalis(雪地衣藻),” said the National Antarctic Scientific Centre of Ukraine in a Facebook post.

These green algae, a type of seaweed, are common in all icy and snowy regions of Earth, from the Arctic to high mountain regions. They lie still during the freezing winter, but once the sunlight warms enough to soften their world, the algae awake, making use of the melt water and sunlight to rapidly bloom.

“The algae need liquid water in order to bloom,” University of Leeds microbiologist Steffi Lutz told Gizmodo in 2016. “The algal blooms contribute to climate change,” the center stated.

A study in 2016 showed that snow algal blooms can decrease the amount of light reflected from the snow by up to 13 percent across one melt season in the Arctic. “This will surely result in higher melt rates,” the researchers wrote.

In 2017 environmental scientists calculated that microbial communities contributed to over a sixth of the snowmelt where they were present in Alaskan ice fields. Their experiments showed that areas with more melt water led to the growth of 50 percent more algae and places with more algae melted further.

This Antarctic summer has certainly seen a lot more melt water than usual. Temperature records keep changing, leading to rapid melting previously only seen in the Northern Hemisphere.

【1】What does the underlined word “culprits” in Paragraph 1 mean?

A.Risks.B.Chances.

C.Effects.D.Criminals.

【2】What can we know about Chlamydomonasnivalis?

A.They can be found anywhere.B.They are sensitive to temperature.

C.They grow slower than before.D.They survive only one melt season.

【3】What can be inferred from the last two paragraphs?

A.Ice and snow will soon disappear in the Antarctic.

B.Microbial communities bring about extreme weathers.

C.The Southern Hemisphere is warmer than the other parts.

D.Climate change and algae growth interact with each other.

【4】Which can be a suitable title for the text?

A.Why Snow Turned Blood-red.B.How Algae Began in the Arctic.

C.Why Climate Changes Greatly.D.How the Snow Reflects Sunlight.

Last weekend, I went hike with some friends. Setting off early in the morning, we gathered at the gate of a park in ours city. Then we headed for our destination. We have planned to climb a hill near the park. On the way, we talked, laughed or sang happily. It took us three hour to reach the top. The wonderfully view from the top made all the efforts worthwhile. We had a nice rest and picnic, sharing that we carried in our bags each other.

Generally speaking,people often return to a set level of happiness despite life's ups and downs,For instance,people who win the lottery tend to return to roughly their original levels of happiness after the novelty of the win has worn off.The same-is true for those who are in major accidents and lose the use of their legs.The change in ability can be damaging at first,but people generally return to their pre-accident levels of happiness after the habituation period.This phenomenon is called hedonic adaptation,a concept studied by positive psychology researchers.

There are activities that are more or less affected by hedonic adaptation.Some of these activities are known as pleasures.They can lift your mood and leave you feeling wonderful,but their effects can be relatively a short time.What's more,we get used to them relatively quickly.If you have the same meal every day for a week,for example,you may find it to be less pleasurable by the end of the week. Gratifications(滿足）are also such activities affected by hedonic adaptation.They can get us into a feeling of"flow”where we don't notice the passage of time,and where we're thoroughly engaged in what we're doing.Gratifications are activities that require more effort and thought,but the payoff is higher as well The more we engage,the more we enjoy!

Knowing that pleasures don't last long in their effects may make them seem less worth the effort than gratifications.There are reasons why they can be perfect for certain situations,however.First,they bring a quick lift in mood without a great deal of effort.This is actually quite valuable because there is significant research that shows that a lift in mood can lead to chain reaction of positive feelings.Second, gratifications do take more effort,so when you only have few minutes or a very limited amount of energy,pleasures are often the simpler and more accessible option.

Thankfully, we can do something to move away from the limiting effects of hedonic adaptation and engage in activities that can create a greater level of happiness in lie.For example,be sure to make time for hobbies!It doesn't really matter what the hobby is;as long as it's one you enjoy,you'll benefit from it,and these benefits will extend into the rest of your life.It's also a good idea to help other people. This can create greater meaning in your life, and thus create greater happiness.Enjoying your positive experiences is also a great way to maximize the positive in your life.So at the end of the day,a few days, a week,write about three things you enjoyed that day.Then,you'll be reliving these positive experience as you write about them,and can relive them again when you read.
