Coffee is one of the most popular drinks throughout the world today. In fact, according to some estimates, over 30% of all adults in the world drink coffee at least once a day on the average.　 Coffee contains a kind of drug called caffeine. Caffeine is a chemical that stimulates (刺激) the nerves of the body. Drinking coffee tends to make people a little bit more awake―at least for a short time―because of this stimulating effect on the nervous system. A cup of coffee has, on the average, about 3% caffeine in it.

One story of the discovery of the coffee plant relates to this effect of caffeine. According to the story, coffee was discovered in East Africa. The story says that coffee was first found by a goat farmer named Kaldi. This was about the year 850. Kaldi was leading his animals through the mountains and the goats were stopping repeatedly to eat the plants near the path. Suddenly, some of the goats started jumping up and down in a very strange way. Kaldi figured out that the goats were acting this way because of the plants they were eating. Kaldi himself tried eating some of the green beans (豆荚) that the goats had been eating. He, too, felt the stimulating effect of the beans.　　 Kaldi wanted to prove what had happened, so he picked some of the beans and took them back to the village, where he told his story.

The green bean got the name "Kaffa" and later "coffee" because the beans were discovered in a place called Kaffa in Africa. Then for years, people used to eat a few of the green Kaffa beans when they were in the mountains and needed extra energy to do their work. It was later found that the coffee beans could be picked and then dried until they turned brown, and then they could be stored. If the beans were dried and stored, they could be used at any time.

1.What is the purpose of drinking coffee?

A. To become more awake.　　　 B. To become more healthy.

C. To become more happy.　　　 D. To become more clever.

2.How did the goats react after eating the plants?

A. They fell asleep.

B. They could not find their way home.

C. They started jumping up and down.

D. They wanted to eat more.

3.Why did the green bean get the name "Kaffa"?

A. Because Kaldi loved his home village very much.

B. Because Kaldi's goats loved the green bean very much.

C. Because the beans were discovered in a place by this name.

D. Because the beans could be picked and dried.

A handshake is one of the most common ways to greet others, but US President Donald Trump’s unusual method has been put under the microscope lately.

Much like an arm wrestler in a match, the recently-elected leader has a habit of yanking (猛拉) people’s hands toward himself during handshakes. And while a typical handshake is only brief, the one between him and Japanese Prime Minister Shinzo Abe on Feb 10 lasted a full 19 seconds.

Simply having a strong hand is not the explanation here. According to Darren Stanton, a body language expert from the UK, while handshakes are usually an exchange of kindness, Trump uses his as a way to show power and control, regardless of how uncomfortable it makes people. “It is as if to say, ‘Hey, I’m in charge, don’t mess with me,’ ” Stanton told The Independent.

Apart from Trump’s “yank-shake”, there are other ways people display power with their hands. At business talks or political meetings, for example, some people may rotate (旋转) their wrists during handshakes so that their hand ends up on top instead of underneath. Some may squeeze so hard that it leaves the other person’s hand in pain.

According to Stanton, by pulling people into his personal space, Trump is also testing whether they are willing to cooperate with him. “For example, if someone was resistant to being yanked towards him and stood their ground, he would know that he has work to do with them before he got what he wanted,” Stanton told Express.

This is probably why on Feb 13 when Canadian Prime Minister Justin Trudeau visited the White House, all eyes were on how he was going to handle Trump’s handshake. Fortunately, Trudeau managed to avoid the embarrassment by grabbing Trump’s shoulder to stop himself being pulled in. Afterward, some Twitter users wrote that this proved Trudeau’s strong leadership, with one even calling the moment “one of Canada’s greatest victories”.

Vice magazine summed up the exchange between the two leaders as: “... no regular handshake. This was the first shot in a bloodless war.”

1.According to Darren Stanton, Trump uses his “yank-shake” to _____.

a. show his kindness

b. gain control

c. remind people of his status

d. see if people are cooperative

e. get people to lower their guard

A. bcd　　 B. abc

C. ace　　 D. bde

2.The phrase “stood their ground” in Paragraph 5 probably means _____.

A. going ahead　　 B. standing still

C. turning around　　 D. pulling out

3.According to the text, the way Trudeau reacted to Trump’s handshake _____.

A. annoyed Trump　　 B. displayed his power

C. was considered rude　　 D. was likely to start a war

4.What can be concluded from the text?

A. Some people spin their wrists during handshakes to show extra respect.

B. Handshakes are the most preferable way for political leaders to greet others.

C. The way someone shakes another person’s hand can have different meanings.

D. The longer two people shake their hands, the better their relationship is.

One way to prevent anxiety from getting out of control is to recognize its benefits. It is a mistake to think that we'd make better decisions if only we keep our feelings under control. Instead, a mix of feelings like anxiety and logical(合逻辑的) thinking leads to sound decision- making. It's true that there is plenty of research showing that higher levels of anxiety can make us more likely to avoid risks in our decision-making. There is also evidence that anxiety can increase the attention you pay to relevant information.

Recent studies have shown that people who are anxious about their relationship (for example, they fear to be abandoned) tend to be better at recognizing people who tell lies and are more likely to raise the alarm when danger is present.

In the real world though, it's worth realizing that feeling anxious once in a while is extremely common. It communicates to others that you care, and what's more, it's probably a sign that you are intelligent. At least two published studies have identified that people who score higher on measures of anxiety also tend to perform better on intelligence tests. This seems reasonable: if you're a thinker, you are sure to be always thinking about the future and imagine possible plots, including bad ones.

The important thing, if you are a worrywart (杞人忧天者) , is not to let your fear destroy your dreams. And don't bury your head in the sand. Instead, act on your fears — do the research as well as preparation, so rather than walking blindly into that which you fear, you meet the challenge in full readiness.

When anxiety beats you, or casts a shadow over your life, this is a serious problem. No one is denying that. But like everyday anxiety of this kind that you feel before a presentation or interview, you needn't see it as your enemy. Anxiety is an important feeling, developed through evolution. As for people who are fairly anxious by nature, there is reason for cheer, too. Your nerves (神经紧张) are a sign of your watchfulness. Listen to them and act on them. Then you can turn your nervousness into your advantage.

1.What can we infer from the first paragraph about anxiety?

A.It can enable us to be more focused.

B.It can stop us from thinking logically.

C.It can make us more willing to take risks.

D.It can be the only reason for all bad decisions.

2.What can we learn from the passage?

A.Anxious people are less sensitive to danger.

B.Anxious people have difficulty discovering liars.

C.Feeling anxious is more likely to put people at risk.

D.Feeling anxious occasionally is a sign of intelligence.

3.How should we deal with anxiety in the author's opinion?

A.Regard it as our enemy. B.Take action to control it.

C.Avoid being defeated by it. D.Treat it as a minor feeling.

4.What is the theme of the passage?

A.Effective ways to prevent anxiety. B.Unexpected benefits of anxiety.

C.Tips on how to keep a good mood. D.Common misunderstandings about anxiety.

Does your pet have a slim figure? According to the Association of Pet Obesity Prevention (APOP), about half of all dogs and nearly 60% of all indoor cats are overweight. Larry Kornegay, president of the American Veterinary Medical Association, says he sees an overweight pet nearly every day, and unusually the owner is overweight. So talking about the topic can be touchy. “I talk about their pet’s health. Still, some clients take it personally.”

Here are some tips for pet weight loss:

See the vet(兽医). Have your vet put together a plan and treat any existing medical problems. Pain relief and diet changes may be required for arthritic(患关节炎的) pets, which will allow for exercise to at least begin.

Skip the crash diet (an attempt to lose weight quickly by strictly limiting the diet). A special weight-loss diet may be suggested. For example, look for the supplement which burns fat and builds muscle mass in foods. Never place any pet on a crash diet, especially cats, which can suffer a potentially fatal liver disease as a result. There’s a safe weight-loss drug for dogs you can ask your vet about.

Dine alone. “Cut out treats and resist temptation by keeping pets out of the room you’re dining in,” says Chicago vet Sheldon Rubin. You can buy low-calorie treats for dogs and cats. Rubin also recommends mini carrots, small apple slices or blueberries for dogs. What’s important is finding other ways, aside from food, to show your love. Play with your cat using an interactive toy, and take your dog for walks. Walks are great for bonding, and good for you. Studies show people are actually more willing to lose weight themselves if it also will help their pet.

Feed pets at special times. Pre-measure food carefully—don’t give them a larger meal than ever—and leave it in various places, so pets sniff it out and use the stairs. It’s fun, and it’s good exercise.

1.The underlined word “touchy” in Paragraph 1 probably means__________

A. sensitive            B. exciting           C. moving          D. pleasant

2.What can be inferred from the passage?

A. Overweight people usually like overweight pets.

B. Pets’ weight is easier to lose than humans’.

C. Cats have a greater chance of serious liver disease.

D. Overweight people often ignore their pets’ weight.

3.Which of the following methods is healthy for your pets?

A. Providing them with mini carrots or blueberries.

B. Keeping them with you when you’re dining.

C. Supplying them with larger meals or drinks.

D. Leaving the food in a fixed place for your pets.

4.What does the passage mainly tell us?

A. How to feed pets without a crash diet.

B. The importance of pet weight loss.

C. How to help pets lose weight.

D. The problems that pets will meet.
