【正文】 periences in the ing decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”63. What are the first two paragraphs mainly about?A. The various patterns at the ocean surface.B. The cause of the changes in ocean colour.C. The way light reflects off marine organisms.D. The efforts to fuel the growth of phytoplankton.64. What does the underlined word “vulnerable” in Paragraph 3 probably mean?A. Sensitive. B. Beneficial. C. Significant. D. Unnoticeable.65. What can we infer from the passage?A. Phytoplankton play a declining role in the marine ecosystem.B. Dutkiewicz’s model aims to avoid phytoplankton changes.C. Phytoplankton have been used to control global climate.D. Oceans with more phytoplankton may appear greener.66. What is the main purpose of the passage?A. To assess the consequences of ocean colour changes.B. To analyse the position of the ocean food chain.C. To explain the effects of climate change on oceans.D. To introduce a new method to study phytoplankton.6366 BADCSection CDirections: Read the following passages. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.A. What you39。re born with isn39。t what you39。re stuck with.B. Where the difference was observed was in connectivity.C. Another more plicated mnemonic （助記憶符）technique is called a mind palace.D. Training in method of loci can physically change the way a person remembers.E. Eating and sleeping right will lead to optimal brain function, the flowon effect of which is a better memory.F. The improved memory observed after mnemonic training persists for as long as 4 months after training concludes.Life would be a lot sweeter if you were a memory athlete. Most of us however, are not wired that way. But don39。t be discouraged: thanks to neuroplasticity, anyone can transcend their fallible memory. 67 There are a few relatively simple things a person can do to help improve their memory function. First up, the basics: the foundation of good memory is good health. 68 Then there are more deliberate approaches like practicing mnemonics. A mnemonic device is a trick designed to make remembering things easier. So instead of remembering to buy eggs, rice, apples and dog food, it might be easier to think of READ, which stands for rice, eggs, apples, and dog food. This is the acrostic method. 69 Let39。s use the same shopping list as an example. Instead of focusing on the word ‘rice,’ this technique works by focusing on the image of rice thrown on the ground in a yard. For eggs, picture a hen pecking at the rice, followed by a nearby tree of apple blossoms, the petals falling around the hen, falling on a sleeping dog. Once the interconnected scene is created it’s a simple visual to ease your way around the halls of the grocery store with no list needed. This technique, where you base a memory around visual images, is more formally called 39。method of loci39。.A recent study published in Neuron has unearthed some interesting insights about the brains of petitive memorizers. The researchers invited 23 of the world39。s top 50 memory athletes to have their brains scanned in rest states, and while performing memory tests, and matched each champion to a control participant. Anatomically, the scans showed there was no difference in brain structure or region size between the groups. 70 And what39。s more, after they gave the 39。naive39。 control group training in the method of loci, their neural connectivity began to look more like that of the pros.6770 AECBIV.

Use your own words as far as possible.Much of the work in today’s world is acplished in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. Sports team owners spend millions of dollars attracting top talent. Is their money well spent?Several recent studies examined the role of talent in the sports world. They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent。 above that level, the team’s performance begins to decline. Interestingly, this trend isn’t evident in baseball, where additional individual talent keeps improving the team’s performance.To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate their actions. This task interdependence distinguishes baseball from football and basketball. In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, for example, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team’s performance. Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tugofwar（拔河比賽）, whenever a person is added, everyone else pulls the rope with less force. Building up a dream team is more plex than simply hiring the best talent. An Ateam may require a balance—not just A players, but a few
