    【题目】 People feel good about recycling, maybe even more so when it comes to electronics. While electronics recycling isn't bad, making it a panacea(万能药) for the e-waste problem we currently have certainly is. Unfortunately, that's how we think of recycling — and companies to jump on that trend to appear more “green”.

    A case in point: Apple. In 2016, there was lots of report on Liam, a robot able to dismantle(拆卸) an iPhone in just 11 seconds — a good way to recycle 1.2 million units a year. That sounds amazing until you take into account the fact that Apple had actually sold 231 million new iPhones the year before. Liam, actually, is the perfect symbol for recycling in the field of high-tech: a drop of green water in an ocean of pollution.

    According to a recent UN report, the US produces about 6.3 million tons or 14% of the world's electronic waste. Worldwide, almost 45 million tons of electronic waste were produced in 2016. Among them, only 20% had been recycled in some shape or form. The remaining 80% made its way to a more environmentally damaging end at the landfill(垃圾填埋场).

    Of course, we can say it's time to double our recycling efforts. However, the huge amount of e-waste is impossible to cope with. The UN report points out that while there is an increased focus on recycling today compared to the past, the effort to reuse used devices simply can't keep pace with the high consumption rates for new devices.

    In their environmental responsibility report, Apple admits that 77% of the carbon footprint of their electronics comes from their manufacture, versus(相对于) 17% comes from its actual use. The environmental effect of replacing a device, even if it is recycled after, remains significant.

    【1】Which of the following can best describe Liam?

    A.It's useful but can't make a big difference.

    B.It's energy-saving but too expensive.

    C.It's well-made but won't become popular.

    D.It's advanced but impractical.

    【2】What caused the e-waste recycling problem?

    A.Few high-tech companies.

    B.Not enough recycling efforts.

    C.High demand for new electronics.

    D.Difficult recycling processes.

    【3】What does the author think of the electronics recycling?

    A.It is very effective.

    B.It is quite good.

    C.It is environmentally damaging.

    D.It is far from “green” recycling.

    【4】What can be the best title for the text?

    A.A Recent UN Report on E-Waste Problem

    B.The Limitation of Electronics Recycling

    C.A Good Way to Cope With E-Waste

    D.The Responsibility for Apple to Decrease E-Waste

    【题目】 We often hear such statements: “I spilled (洒出) juice, but it wasn’t my fault.”, “I got in trouble at school, but it wasn’t my fault.” or “I was in a car accident, but it wasn’t my fault.” That “It’s not my fault.” is a go-to response for so many people and especially teenagers.

    Parents complain they are tired of the “excuse”. The reason why variations of “It’s not my fault.” are so popular is that it lets us off the hook from guilt and blame. I’m a fan of not owning responsibility for things that I can’t control. Teens who often say “It’s my fault.” when something bad happens tend to be highly self-critical, perfectionistic and more easier to be troubled by anxiety and depression.

    While it is important to recognize lack of reason to blame oneself, many teens over-rely on “It’s not my fault.” When trying to get them to take responsibility, parents usually attempt to convince their teens that something is their fault. The approach tends to be ineffective and turn into a power struggle. No one wins. A more effective approach can be to stress significant drawbacks to consistently focusing on removing our responsibility with this phrase.

    Overuse of the phrase can result in feelings of lack of ability to control their own lives. This sense has been shown to cause low motivation. Besides creating feelings of lack of ability, overuse of “It’s not my fault.” focuses a teen’s attention on what is done as opposed to what needs to be done.

    People may not have caused all their problems but they have to solve them anyway. The example I frequently share with teens is the question of what one will do if he is pushed into a deep lake. One can certainly stay in water, yelling, “It’s not my fault.” However, that won’t get him out of water. He needs to swim to the shore, regardless of the fault.

    If you take a proper approach to communicating with your teens, you can help them avoid over-reliance on “It’s not my fault.”

    【1】What phenomenon is described in Paragraph 1?

    A.The teenagers’ dislike for school life.

    B.The common trouble faced by teenagers.

    C.The reasons for blaming others for accidents.

    D.The tendency for people not to be responsible for mess in life.

    【2】What type of teens tends to suffer great mental pressure according to the text?

    A.Those lacking confidence and ambition.

    B.Those allowing others to find excuses.

    C.Those unable to get along well with others.

    D.Those often blaming themselves for some incidents.

    【3】What’s the author’s attitude to parents’ usual way of guiding children?

    A.Supportive.B.Negative.

    C.Ambiguous.D.Neutral.

    【4】What lesson is conveyed in the example often shared by the author?

    A.We should try to avoid troubling others.

    B.We should focus on how to solve problems.

    C.We should dare to point out others’ mistakes.

    D.We should be self-critical as much as possible.
