(London)If it really is what's on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn't surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body's communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.

【解析】
文章大意:本文讲述了很多表面很瘦的人实际上内部器官里的脂肪不一定就少,号召人们要通过锻炼来减肥,而不是仅仅是节食。
1.A 细节理解题。根据文章第3段“Being thin doesn't surely mean you are not fat,”以及第4段According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.可知瘦并不意味着你就不胖,很多节食但是不锻炼的人实际上在内部也有很多的脂肪。故A正确。
2.2】D 主旨大意题。根据文章1,2段If it really is what's on the inside that counts, then a lot of thin people might be in trouble.和Some doctors now think that the internal fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily可知在人体内部堆积的脂肪对人的健康也有很大的威胁。瘦的人的体内也可能有很多脂肪。故D正确。
3.3】A 推理判断题。本文只是讲述很多表面不胖的人,实际上也可能在内部器官里堆积了很多的脂肪。并不是说患心脏病的人体内都含有很多的脂肪。故A说法是错误的。

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.
Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牵牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meateating plants,” they added.
1.Tomatoes and potatoes kill insects to ________.
A.get more sticky hairs
B.make themselves grow better
C.make their roots stronger
D.avoid falling down to the ground
2.The word “carnivorous” in Paragraph 3 most probably means ________.
A.fastgrowing B.harmless

Pupils remember more and behave better when 3D images areused in lessons,research suggests.They are quicker to learn andabsorb new concepts,and display higher levels of concentration.
Professor Anne Bamford,of the University of the Arts,London,studied the effectiveness of 3D content in 15 schools across seven countries,including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks,improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding,increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology90 percent of those in the study had seen a 3D film.Schools would need 3Denabled projectors(投影仪),laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
But Danny Nicholson,an educationist,said the technology would be impractical to use inschools and could be costly.He said,“While I think the idea of 3D technology is very interesting,I worry that 3D is a bit of an expensive gimmick(小玩意儿).There are a few cases where a true3D image might help,but most of the time,good 2D models that can be moved would be just aseffective.”
In the US,one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
1.What is the main idea of the first three paragraphs?
A.There are slight differences between 3D and 2D images.
B.Pupils perform better when 3D images are used in classes.
C.Schools have difficulties in making full use of 3D technology.
D.3D technology is always more effective than 2D technology.
2.Danny Nicholson holds the view that 3D ________.
A.is of no help in classes
B.has a bright future in classes
C.is more practical than 2D models
D.may not be affordable for schools
3.What can we learn from the last paragraph?
A.3D technology will replace 2D models in the future.
B.Many pupils are now more Interested In science than before.
C.Teachers will use the 3D technology through specific training.
D.3D will soon be put into use in one school district in Colorado.

On May 23rd the United States Department of Agriculture will meet to discuss the pressing topic of wild pigs. These beasts, which number 6 million or so, are an increasing bother. At their worst, they can damage crops, spread diseases, attack humans and kill farm animals. And things are getting worse: a study show that they are likely to double in number over the next 3 years. Why is it so hard to control wild pigs?
Introduced to America in the 16th century, and related to the wild pigs found in Europe, wild pigs can be found in 75% of all states. No single law exists to control them and regulations differ between states: while in Missouri they can only be shot if met by chance, in Texas hunting is actively encouraged. A “pork chopper” law allows Texan hunters to shoot wild pigs from helicopters, and some people in Louisiana have even built their own pighunting drone(无人机). As well as being popular with hunters, wild pigs are cheaper for game raisers to breed(饲养)than deer. In Michigan and Pennsylvania suggested bans on the private breeding of pigs for hunting have caused quarrels between game raisers and wildlife officials.
Wild pigs' double nature——considered pests by farmers, but valued by hunters——makes it hard to pass laws to control them. Two other factors also contribute. Nearly 70% of land in America is privately owned. And it is difficult for lawmakers to impose(强加)breeding and hunting laws on private landowners. Secondly, it is hard to define a wild pig.
In some states, laws are being introduced to redefine the term “wild animal” to keep out wild pigs. This is good news for those raising pigs for hunting, but less are to those who consider them pests whose number should be limited. Meanwhile, discussions continue over how to deal with this problem.
1.People are not permitted to hunt wild pigs freely in ________.
A.Texas B.Michigan
C.Missouri D.Louisiana
2.Why do the game raisers prefer raising wild pigs to deer?
A.It's difficult to raise deer.
B.Wild pigs are in large numbers.
C.Deer are not popular with hunters.
D.They can benefit more from wild pigs.
3.Which is NOT the reason for the difficulty in controlling wild pigs?
A.The difficulty of passing effective laws.
B.The high percentage of land owned privately.
C.The farmers' unwillingness to shoot wild pigs.
D.The popularity of raising wild pigs in many states.
4.What is the best title of the text?
A.Why are wild pigs so hard to control?
B.Are wild pigs pests or wild animals?
C.Wild pigs——an increasing danger in the US.
D.How to deal with the problem of wild pigs?
