【推荐1】These days, are you spending more time feeling guilty about not working out than working out? If so, you’re probably the kind of lapsed boomer. You’ve joined the 4-in-10 adult Americans of all ages who admit they’re not physically active at all, according to the President’s Council on Physical Fitness and Sports.

Exercise experts like Richard Cotton and Cedric Bryant have heard it all before — busy boomers complaining that, between car pools and van pools and making ends meet, they hardly have time for a movie, much less regular exercise. Here are some of their best tips.

Prepare.

Plan your workout wardrobe so you’ll be comfortable. Consider the weather you will be walking in and decide: long pants, long sleeve, shorts, hat?

Don’t skimp (克扣) on shoes.

Which type? “If you are walking with the hope of jogging finally, buy running shoes,” says Cotton. If you plan to walk as your main exercise, get walking shoes.

Start slowly.

“Do much less than you think you are able to,” Cotton suggests. Take a 10-minute walk if you’re newly back to workouts. It’s not enough, “but it’s a start.” Consider walking as a good way to get back to exercise.

Do the talk test.

If you can’t talk without difficulty as you walk or jog, you’re going too fast and trying to do too much, Bryant says.

Consider getting an exercise buddy (同伴).

That could help increase your faithfulness to your new habit. “An exercise partner is always nice”, Cotton says, “especially if you can get someone who already has the habit. That’s a free ride.”

Be realistic about the payoff.

You might notice looser waistbands but no difference on the scale. “As you get up into 35-, 40- or 45-minute walks, you can expect weight loss,” Cotton says. “But even if you do not lose a pound, you are healthier if you exercise.” And quite possibly, that might put you higher up on Bush’s invite list, should he host another run.

【推荐2】For some people, holiday travel includes more than simply hitting the road or braving the airport to get to their destination.     1     . Whether it’s a way to save money, or spend more time with loved ones — it’s important to keep in mind that you’re a guest in someone’s home. Even if your host invited you to stay and said that it was “no trouble at all”, know that accommodating you does take time and energy (and possibly money).     2     . Here are a few mistakes to avoid when you stay in someone’s house.

Showing up unannounced

This really should go without saying and applies to any type of visit to someone’s home, any time of the year -- don’t show up at someone’s door unannounced, or assume you can stay with them without asking first.     3    , one of which is out of respect for your (potential) host, but if that’s not motivation enough, consider the possibility that they may not be home, or have made other plans, and may not be able to put you up.

Ignoring house rules

Did your host ask you to leave your outside shoes at the door? Or perhaps they requested that you say something in a low voice after 9 p.m.?     4     — which you should discuss with your host — you need to follow their house rules. If they didn’t mention any when you first arrived, initiate that conversation yourself.

    5    

When you’re an overnight guest in a friend or relative’s home, you cannot expect the service of a hotel. Your host is doing you a favor by letting you stay in their home for free, so don’t expect someone to make your bed or clean up after you, meals prepared for you, or to have the run of the place.

A．The least you can do is not make things harder for them

B．It also means overnight stays with family or friends

C．Unless you have an excuse

D．Acting like you’re staying in a hotel

E．If you have any unexpected arrangement

F．There are many reasons not to do this

G．Keeping the room tidy as a guest

【推荐1】Facebook is working on automatically flagging offensive material in life video streams, building on a growing effort to use artificial intelligence (人工智能) to monitor content, said Joaquin Candela, the company’s director of applied machine learning.

The social media company has been involved in a number of content moderation debates this year, from facing international outcry after removing a Vietnam War photo to allowing the spread of fake news on its side.

Facebook has historical relied mostly on users to report offensive posts, which are then checked by Facebook employees against company “community standards” . Decisions are especially troublesome content issues that might require policy changes are made by top executives of the company.

Candela told reporters that Facebook was increasingly to using artificial intelligence to find offensive material. It is “an algorithm (算法) that detects violence, or any of the things that are not according to our policies”, he said.

The company already had been working on using automation to flag extremist video content as Reuters reported in June. Now the automated system also is being tested on Facebook Live, the streaming video service for users to broadcast live video.

Using artificial intelligence to flag live video is still at the research stage and has two challenges, Candela said. “One, your computer vision algorithm has to be fast, and I think we can push there, and the other one is you need to prioritize (优先区分) things in the right way so that a human looks at it, an expert who understands our policies, and takes it down.”

Facebook said it also uses automation to process the tens of millions of reports it gets each week, to recognize copied reports and route the flagged content to reviewers with appropriate subject matter expertise.

Chief Executive Officer Mark Zuckerberg in November said Facebook would turn to automation as part of a plan to identify fake news. Ahead of the Nov. 8 U.S. election, Facebook users sulfate saw fake news reports incorrectly declaring that Pope Francis supported Donald Trump and that a federal agent who had been investigating Democratic candidate Hillary Clinton was found dead.

However, determining whether a particular command is hateful or bullying, for example requires context, the company said.

Yann LeCun, Facebook’s director of AI research, declined to comment on using AI to detect fake news, but said generally news feed improvements provoked questions on how to access the content. “These are questions that go away beyond whether we can develop AI.” said LeCun.

1. What has Facebook mainly used to monitor content in history?

A．Artificial intelligence.	B．Reporting from Facebook users.
C．Top executives’ judgment.	D．Facebook employees’ checking.

2. Which of the following statement is TRUE?

A．The company began to use automation last June.

B．The company has depended on AI to monitor content.

C．Opinions differ about the “community standards”.

D．Using AI to monitor content is a simple and easy way.

3. The following are the challenges in using AI to monitor content EXCEPT that                                          .

A．you have to make comments on the materials

B．things need to be prioritized in the right way

C．you need to understand the context of the content

D．the computer vision algorithm has to be fast

4. Which can replace the underlined word “provoked” in the last paragraph?

A．Hid.	B．Caused.
C．Discussed.	D．Answered.

【推荐1】In simpler times, we never had to consider a loved one’s privacy when gift-buying. But as technology has continued its high-speed advance and growth at all costs, many companies and the products they create have long been skirting (回避) adequate data and privacy protection, leaving users at risk. For example, the audiobook reader you give to your children to send them to sleep at night now captures data on what they like.

As we continue to integrate (整合) the Internet into more of our devices and cover our homes and lives with cameras, microphones and trackers, the lack of data protection and privacy is becoming dangerous. Very few companies are being honest about how they collect, store and use data, and the only loser is the very individuals who use these products.

But that, right there, is the one chance consumers have to turn the tide (扭转局势).

The change starts with us. Buying a small device isn’t simply buying a product any more; it’s a conscious decision about whether you trust the company behind it to work in your best interests and keep you safe. It’s your responsibility as a consumer to be aware of this choice and act on it. In an ideal future, it won’t require hours of research — whether done by the buyer or by organizations — to buy safe, responsible products. But for now, it’s the best option available as these companies continue to get a free pass.

We can demand more. We must demand more. We can demand that privacy and security be taken seriously by the companies who build the products we buy. Yes, technology has vastly improved our lives, but that shouldn’t come at the cost of our safety. So if you want to give someone a gift, give them the gift of privacy. It’s the only way to make the Internet — and our lives — a little safer in this digital world.

A．Gift-buying nowadays is much more complicated.

A．We can better protect our privacy.	B．They will make our life more convenient.
C．We are more likely to reveal our privacy.	D．More companies will keep watch on them.

3. What does the underlined phrase “get a free pass” in Paragraph 4 mean?

A．Do as they wish.	B．Mislead the users.
C．Shift the responsibility.	D．Offer services free of charge.

4. What is the main purpose of the passage?
