【题目】阅读理解。
Enough “meaningless drivel”. That’s the message from a group of members of the UK government who have been examining how social media firms like LinkedIn gather and use social media data.
The House of Commons Science and Technology Committee’s report, released last week, has blamed firms for making people sign up to long incomprehensible legal contracts and calls for an international standard or kitemark (认证标记) to identify sites that have clear terms and conditions.
“The term and conditions statement that we all carelessly agree to is meaningless drivel to anyone,” says Andrew Miller, the chair of the committee. Instead, he says, firms should provide a plain-English version of their terms. The simplified version would be checked by a third party and awarded a kitemark if it is an accurate reflection of the original.
It is not yet clear who would administer the scheme, but the UK government is looking at introducing it on a voluntary basis. “we need to think through how we make that work in practice,” says Miller.
Would we pay any more attention to a kitemark? “I think if you went and did the survey, people would like to think they would,” says Nigel Shadbolt at the University of Southampton, UK, who studies open data. “We do know people worry a lot about the inappropriate use of their information.” But what would happen in practice is another matter, he says.
Other organisations such as banks ask customers to sign long contracts they may not read or understand, but Miller believes social media requires special attention because it is so new. “We still don’t know how significant the long-term impact is going to be of unwise things that kids put on social media that come back and bite them in 20 years’ time,” he says.
Shadbolt, who gave evidence to the committee, says the problem is that we don’t know how companies will use our data because their business models and uses of data are still evolving. Large collections of personal information have become valuable only recently, he says.
The shock and anger when a social media firm does something with data that people don’t expect, even if users have apparently permission, show that the current situation isn’t working. If properly administered, a kitemark on terms and conditions could help people know what exactly they are signing up to. Although they would still have to actually read them.
【1】What does the phrase “ meaningless drivel” in paragraphs 1 and 3 refer to?
A. Legal contracts that social media firms make people sign up to.
B. Warnings from the UK government against unsafe websites.
C. Guidelines on how to use social media websites properly.
D. Insignificant data collected by social media firms.
【2】It can be inferred from the passage that Nigel Shadbolt doubts whether _______.
A. social media firms would conduct a survey on the kitemark scheme
B. people would pay as much attention to a kitemark as they think
C. a kitemark scheme would be workable on a nationwide scale
D. the kitemark would help companies develop their business models
【3】Andrew Miller thinks social media needs more attention than banks mainly because _______.
A. their users consist largely of kids under 20 years old
B. the language in their contracts is usually harder to understand
C. the information they collected could become more valuable in future
D. it remains unknown how users’ data will be taken advantage of
【4】The writer advises users of social media to _______.
A. think carefully before posting anything onto such websites
B. read the terms and conditions even if there is a kitemark
C. take no further action if they can find a kitemark
D. avoid providing too much personal information
【5】Which of the following is the best title of the passage?
A. Say no to social media?

【题目】阅读理解。
A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.
Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.
The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.
Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.
Night milk quickened the start of sleep and caused the mice to sleep longer.
While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.
Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.
Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.
【1】According to the text, the mice fed with daytime milk_______.
A. started sleep more easily
B. were more anxious
C. were less active
D. woke up later
【2】Which of the following is true of melatonin according to the text?
A. It’s been tested on mice for ten years
B. It can make people more energetic
C. It exists in milk in great amount
D. It’s used in sleeping drugs
【3】What can be a suitable title for the text?
A. Night Milk and Sleep
B. Fat Sugar and Health
C. An Experiment on Mice
D. Milk Drinking and Health
【4】How does the author support the theme of the text?
A. By giving examples.
B. By stating arguments.
C. By explaining statistical data.
D. By providing research results.

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Everyone knows that fish is good for health. 【1】 But it seems that many people don’t cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn’t difficult. 【2】 This text is about how to buy and cook fish in an easy way.
【3】 Fresh fish should smell sweet: you should feel that you’re standing at the ocean’s edge. Any fishy or strong smell means the fish isn’t fresh. 【4】 When you have bought a fish and arrive home, you’d better store the fish in the refrigerator if you don’t cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn’t as tasty as the fresh one.
There are many common methods used to cook fish. 【5】 First, lean it and season it with your choice of spices(调料). Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time.) Then, it’s ready to serve.
A. Do not buy it.
B. The easiest is to steam it.
C. This is how you can do it.
D. It just requires a little knowledge.
E. The fish will go bad within hours.
F. When buying fish, you should first smell it.
G. The fats in fish are thought to help prevent heart disease.
